How Do Green Roofs Create Value?

green-roof-benefits-alta-roofing-los-angeles

 

Discover all the positive effects a green roof can have for energy costs, ecology, community and well-being. Read on to find out about the convenience of vegetation blankets, for rapid installation of a full-coverage green roof requiring negligible maintenance.

A Natural Air and Water Purifier

Your green roof will contribute to purifying and de-polluting the air, producing oxygen out of carbon dioxide and filtering particulates. It purifies rainwater too, and facilitates evaporation from the plants.

The plants and the substrate and drainage layers around them also provide a rainwater buffer. This has benefits for the local groundwater and sewage systems, delaying rainwater discharge and reducing the load and risk of flooding after heavy rainfall.

Cooling Effect

The plants on a green roof reduce the ambient temperature. They absorb one half of the sunlight that reaches them, and reflect another 30%. That makes a pleasantly cool climate, reducing temperature in the building’s immediate neighborhood.

Inside, the building’s cool air systems have less work to do, reducing energy bills and extending the life of your air conditioning. And if you use solar panels already, or take the opportunity to install them with your green roof, you’ll find the cooler roof surface provides conditions for the panels to operate more efficiently. Energy is channeled into your power supply instead of being lost as heat, and your energy costs are further reduced.

A Roof Saver

Upgrading to a green roof won’t just preserve your aircon. It could triple the lifetime of the roof itself. Protected from the strongest sun, rain, temperature extremes and wind the weather can throw at it, a roof structure can be good for 60 years. In maintenance costs alone, a green roof can recoup your investment in as little as 8 years.

Quieter, More Pleasant Environment

A green roof will act as a sound barrier, absorbing external noise with particular appeal in urban areas. It makes for a quieter environment outside as well as within the building. It’s a more relaxing space that promotes well-being. Greenery offers a positive environment that encourages people to unwind and reduce their stress level, whether it’s at the end of the working day or for convalescent patients. People can tolerate pain a little more in a healing, green environment and require a shorter stay at the hospital.

Plants, herbs and grasses in a green roof encourage biodiversity. It provides a habitat for birds, butterflies and other insects and will attract more life than any gray, concrete and glass building.

Brings People Together, Reduces Vandalism

Everyone living in a green environment has a higher perception of their space and quality of daily life. They’ll naturally work together to maintain it. An environment people take pride in has positive social effects: more interaction and cohesion in the community. Greener areas are proven to suffer less violence, aggression and vandalism.

Vegetation Blankets Save Time And Maintenance

Direct-green mats pre-cultivated with greenery are delivered with 90% coverage, way quicker and easier to install than establishing a green roof with individual plug plants. An attractive green roof can be realized in a very short time.

Vegetation blankets bring great benefits going forward too. They make a solid top layer for the green roof that resists erosion, protecting substrate from blowing away in a storm. The nearly-full coverage means weeds struggle to get established, and very little effort and cost is required for maintenance.

Adding Value to the Building

A building with a green roof gains an attractive appearance with much more appeal than grey, man-made structures. Its strong, sustainable image adds value, as do the reduced energy and maintenance bills.

A green roof brings much more than just visual appeal to your property. It’s a sound economic investment which brings multiple savings in energy costs, maintenance and repair costs. You and other residents will benefit from clearer, cooler air, reduced noise and better climate proofing. And a green roof gives back to the local area, encouraging biodiversity and doing its bit to regulate the wastewater supply and ambient temperature.

Your Roof’s Condition Can Affect Your Property Insurance Coverage

Roof-Affect-Property-Insurance

 

 

You may not know this but if your roof is in poor condition your insurance company may require that an actual cash value percentage of the room is excluded from your insurance policy.

If your roof is not in the top position than this cash value can be a lot less. They may exclude coverage for the entire roof. Other companies may only cover portions of the roof that tend to be newer or in good conditions. Many insurance companies state that a pre-coverage inspection of the roof is required for a new policy or the renewal of an existing policy. Someone from the insurance company will come to the home and inspect the roof before a policy is issued. For many years commercial buildings were required to have a roof inspection as part of the insurance underwriting process. If the roof of a commercial building was in poor condition it was considered to be a high risk. If a customer got hurt due to the condition of the roof the insurance company would have to pay out a settlement. Many insurance companies are new requiring roof inspections for residential insurance policies. They want to reduce the risk of a payout and repair to the roof. These repairs can be very expensive. There are some insurance companies that will cancel your policy if your roof is in poor condition.

Many people do not pay attention to their roof unless there is an issue such as a leak. You may not have looked at your room in a long time. Every so often an insurance company will send an inspector to check out your property. This will walk around and take some pictures. If they see there is an issue with the roof they want threaten to cancel the policy. Some insurance companies will give you a chance to make any needed repairs to your roof. If the repair are not made within a certain period of time and proof is not sent to the insurance company your policy will be canceled.

To understand what your property insurance policy is going to cover and the areas that it is not going to over you need to contact your insurance agent or the insurance carrier. This information is very important. If something happens to your home you need to know what the insurance company is going to cover and what is not going to be covered under your policy. The coverage for the roof will depend on the age of it and the condition that it is in. Older roofs are a higher risk for the insurance company. The average lifespan of a roof is around 20 years. If the roof is nearing this age the insurance company will view it as a risk for replacement and may not cover it in the policy. It is essential that you know what your property insurance covers and what is not covered in the policy. While it is a good idea to read the coverage options that are listed in your policy speaking to someone will give you the best results. They will also be able to answer any questions that you may have about your coverage.

Replacing your roof or even restoring the existing roof is very expensive and will take up a lot of time. It is important to take steps to prevent the roof from becoming damaged. These preventative measures can improve the lift of your roof. There are little things you can do to extend the life of your roof. The roof should be inspected annually. This way small repairs can be made to help prevent bigger problems. You also want to remove anything that is clogging the gutter. This will help prevent backup into the home. Be sure to check the shingles if you have them and make sure they are secure.

You need to remember that property insurance is not a warranty on the home. This policy is a risk that is shared between the owner of the property and the insurance under writing company. It is in your best interest to keep your roof in good condition and have it inspected annually.

6 Factors that Affect Your Roof’s Life Expectancy

roof-life-expectancy

Even if you have a high quality roof, which will protect your home for a couple of decades, they do not last forever. You should always have regular inspections by a roofing contractor as well as periodic maintenance. Contractors can let you know when you can expect to have to replace the roof.

Regular maintenance is the best way to ensure your roof lasts a long time but there are six key factors that determine how soon and how often your roof may need repair or replacement.

  1. Roof Material

Each roofing material has different endurance and offers different life expectancy. If you have asphalt shingles you can expect the roof to last a few decades. The materials that provide even longer cover include clay or concrete tiles, slate shingles and membrane systems. When it comes time to replace your roof, consider using materials that have longer life expectancy. Work with you roofing contractor to determine the best materials to use for your building and local environment.

  1. Weather

Not something you can control but can be prepared for is the weather. Most systems are designed to endure heavy rains, strong winds even snow and hail, but this does wear them down. Extreme weather conditions can really take their toll on your roof, so depending on where you live your roof may be exposed to severe conditions that damage the structural integrity. Consider the climate you live in and keep your roof maintained accordingly. Perhaps check with local contractors for protective tips if you live in areas prone to harsh weather.

  1. Sun Exposure

The damaging UV rays of the sun can hurt your roof just like they hurt us. Some materials like metal or EPDM rubber membranes are more resistant to the ultraviolet exposure. Most roofing material will degrade with the repeated radiation. Continued sun exposure weakens the structural integrity of a roof by heating it. This causes thermal shock to the materials as well as contraction and expansion. Once this happens, the material degradation is accelerated causing roof repair and replacement to be sooner than expected. Since the sun is not something you can control, it is advised to check with professional roofers for any tips or protective additions that can be utilized.

  1. Roof Pitch

Longevity of a roof is also affected by its pitch or angle. Roofs that are flat and low do not get rid of water easily so it builds up. When rain or snow are allowed to accumulate on the surface it starts to wear away the materials. Pools of water cause the materials to lose strength which can cause leakages. A good way to offset the damage is to install gutter systems and make sure they are kept clear of debris build up, so they can efficiently remove water away from the roof.

  1. Ventilation

Every building should have proper ventilation. Regular air circulation through the house and attic prevents moisture from accumulating and also reduces the external temperature. When ventilation is poor, roof materials are weakened and not as effective. It is wise to consider which option works out better in the long run, replacing materials more frequently or investing in a good air ventialation system.

  1. Proper Installation

A quality installation goes a long way in roofing. When cheap or inexperienced roofers are used it is not uncommon for there to be premature repairs and replacement. While you save money in the beginning, you will have unexpected costs with leaks and other damage that occurs without proper installation. The use of lower quality materials also contributes to early degradation. You want to be sure you hire a licensed professional that uses high quality materials and ensures their work is up to all codes. In the event a genuine error occurs, professional contractors are always willing to return and make it right.

Roofing repairs and replacement is not cheap, so you want to make sure you get the most out of the roof you have. By investing the time to care for it and considering the above factors, you can expect to get more longevity from your roof.

Would You Trust a Drone Service for Your Roof Inspection?

drone inspection

You really shouldn’t invest in a new building or home until you’ve had a roof inspection, even if you think you’ve found the one. You don’t want to buy a building or home with weak or damaged roofing, then find yourself with hefty bills to repair leaks and structural damage.

One of the latest technologies inspectors are often using to evaluate a roof involves using a drone.

But roofing contractors perform this importantl task differently, preferring a close-up, hands-on examination. Can you trust a drone inspection? Or should you hire a roofing contractor instead?

How Roof Inspections Work with a Drone

Many home inspectors today don’t actually get up on the roof to check its condition. And many of those who do climb up may stay on the ladder and look at the roof from there. The high cost of liability insurance is the most common reason cited for this worrisome trend.

So to avoid injury to the inspector — and to prevent damage to the building — many roof inspections are performed with a drone.

How does that work? A drone pilot flies a helicopter-like machine, that’s outfitted with a camera. The drone can be adjusted to view different angles, and it can hover to zoom in on selected areas on the roof. As the drone flies, it takes photographs and videos to allow the inspector to evaluate the roof’s condition.

How Roof Inspections Work with a Professional Roofing Contractor

A professional contractor doesn’t rely on drone photos or videos to determine the structural integrity of your roof.

Roofing contractors actually climb up on the roof to look at the roofing materials, underlayment and, if applicable, the roof decking itself.

During a professional roof inspection, the contractor also evaluates the condition of the flashing around the chimneys and vents as well as the soundness of the rain gutters, drains and downspouts. He also examines the deck and structural supports from the attic side.

Professional Roof Inspection vs. a Drone Inspection

A drone inspection gives results that are easy for inspectors to review. And pictures or videos often speak louder than words. With a drone inspection, buyers and sellers can see any roof damage for themselves.

That said, relying on a drone service may not be the best plan. Overhead photos cannot adequately assess any underlayment or deck issues, nor can drones check from inside for water damage or structural support problems.

A roofing contractor will perform a much more in-depth analysis of the roof, manually testing the strength and flexibility of the shingles or tiles as well the other materials. Drone pictures can let you see the rooftop, but only a professional roof inspection will provide you a clear view of the structure’s condition.

How To Avoid a Roofing Scam

how-to-avoid-roofing-scams---commercial-roofing-los-angeles

Good roofs are a great investment. Not only do they protect you better from harsh weather but they also make your building more valuable. For this reason, you do not want inexperienced or illegitimate roofers handling the repair of your roofs, and we cannot deny that we live in a world full of scammers, who can come to you claiming to be professional roofing contractors. How do you know that you are dealing with a scam, and what ideas should raise the red flag that you are being scammed? Read on as in this text are some of the signs to tell you that you are dealing with a scam.

  1. Roofers who offer to repair your roof at no charge

This is the first tip to tell you that you are dealing with a scam. No roofer should come knocking on your door and offer to repair your roof on the basis that your insurance company will pay for it. After all, how would anyone know about your insurance policy? A reputable roofer should come to your office or home and inspect the damaged roof even before the repair. Moreover, if your insurance company will pay for the expenses, it shouldn’t happen fast and without being notified. You need to be there and sign the documents required before the roofer repairs it. So be aware of storm chasers and do not allow anyone who claims to be a roofer to fix your roof until you can guarantee that the contractor is genuine.

  1. Contractors who say that they want to inspect your roof

You need to be aware of roofers who come claiming that they want to inspect your roof when they do not have the necessary licenses. No roofer should come to you home requesting to examine the extent of the damage, while they cannot tell you the company they work with or if they do not have the licenses. Avoid allowing any roofer to get to the roof as some scammers want to damage your roof so that they have something to repair. Also, do not believe any repair man who comes down with some pictures claiming that that is the extent of damage after inspecting the roof. Some people come along with pictures just to convince you that you need a fast repair so that you do not hesitate to hire them.

  1. Roofers who request to assist with your insurance

Some scammers will come and ask to sign your insurance benefits, on the claim that they are well connected with your insurance company and that they can make your compensation fast. Avoid falling a victim of such scams. While this deal may seem great and one to save you much time and money, avoid to accept it. You might end up losing your entire compensation to such people, and even end up losing contact with them.

  1. Roofers who want you to sign a contract immediately

Be wary of a contractor who asks you to sign a contract with them once you meet them. Think about it, why should someone seem to be pressuring you to repair your roof? Maybe, their service quality is not that good, or they do not offer quality material meaning that they just want you to help them earn as they do not get many customers. So, do not sign a contract until you have visited the company’s place of work and even talked with a variety of clients who have benefited from the services of your roofer. Also, do not sign any contract without fully reading and understanding it. Remember, once you sign a contract without agreeing with several issues stated in it, you will be held liable. So, stay away from people who ask you to sign their contract unless you fully agree to it, and you are sure that you are dealing with legit roofers.

  1. Roofers without the proper credentials

Reputable roofing contractors always walk with their business cards, licenses, and insurance. So, do not fall prey of people who come requesting to help repair or replace your roof, while they cannot provide you with these documents. How do you prove that such a person is authorized by the state to repair your roofs, and how can you be sure that you will be insured should a damage result? So, if someone who proves to be a roofer cannot prove that he is, do not allow him/her to your roof. Also, if such roofers come with a vehicle that isn’t branded with the company’s name, that should be an indication that they are not legit.

  1. contractors who promise to replace your roof at a very low cost

This is another trick that scams use. It is no doubt that many homeowners will prefer to hire a contractor who can repair or replace a roof at a low cost, as most people look at the saving factor. However, do you know that you might end up losing more money and even spending more by undertaking such an action? Avoid persons who promise low prices, as this may be an indication that they are not qualified, or that they use inferior materials. You need to research the authenticity of such persons thoroughly. Ask them for references and their certifications. If they cannot provide you any of these, stay away as you do not want to fall a victim.

 

If you come across contractors with these behaviors, you should have the idea that you are probably dealing with a scam. Always be cautious and avoid giving in to such individuals. Do not let promises blind you, as giving in to promising people may just be the beginning of your problems. Take time to assure yourself that you are dealing with reliable people, and only then, sign an agreement.

With any commercial or industrial roofing investment it is crucial that property managers and business owners across Southern California are able to receive both a return of investment and long-term benefits on their spending. There are distinct advantages in replacing an old flat roofing system with a modern system. Newly installed flat roofing systems, if installed right will be more dependable and require less maintenance in the long run and whether you choose PVC or Modified Bitumen roof, you may benefit from higher energy savings and efficiency.

By working with us, an experienced commercial roofing contractor, we will be able to strategize and form a long-term relationship with you from the beginning of the new install to the end of the flat roof’s service life. This allows for a historic knowledge of the flat roofing system and easy maintenance. With this planning you can avoid the headaches and stresses when it comes to roof management and flat roof leaks.

As soon as the new commercial roof is installed, your building is worth substantially more than it was under the old, deteriorating roof. The building will be more secure, more weather-tight, and more attractive.

But exactly how much can you get in return from a new flat roofing system?

There is no question that a flat roof replacement is expensive. Seeing the total price for a professionally completed replacement can cause eyebrows to raise and hearts to skip beats. However, when property managers grasp a true understanding of where the money on a new flat roofing system is being spent, they will see saved dollars in the long-term and how a flat roof replacement is a true investment.

For those considering on selling a commercial property,  installing a brand new flat roofing system could be very profitable. If the sale of your commercial or industrial property is a step you are looking to take, you should take into consideration what prospective buyers expect from a flat roofing system and building efficiency. Low maintenance costs, durability and a long life cycle flat roof is ideal.

By replacing a flat roof with a durable and reliable flat roofing membrane, you not only reduce future spending on flat roof repairs, but you also eliminate costs associated with the damage a leaking roof can cause. With green roof bylaws that require energy saving credentials, you could end up saving thousands of dollars more than the costs required to achieve it.

How To Get Your Roof Ready For Solar Panel Installation

solar-panels-on-flat-roof-los-angeles

When you’re planning solar panel installation at your home or business, you must make sure that your roof can support your sustainable energy goals.
Take these three simple steps before installation of your new photovoltaic array, and you can rest assured that your roof will be ready to support your solar panel installation.

Step One: Contact a Licensed Roofing Contractor and Schedule a Free Roof Inspection

Do you know if roof can support the weight of a photovoltaic array? Solar panels are pretty heavy — each weighs about 40 pounds, not including the mounting racks and hardware. To provide enough power for your building, you may need dozens of solar panels. And your roof must have the right structural support in place to bear the weight of all that equipment. The best way to figure out if you have enough structural support is to schedule a roof inspection. A licensed roofing contractor can assess your roof’s condition.

Step Two: Get The Roof Repaired Before Installing Solar Panels

If during inspection the roofing contractor finds that your roof has some obvious damages, you need to address those problems now. It’s important that you have all repair work done before installing a photovoltaic array. Solar panels last at least 25 years, and most continue to provide power for much longer than that. Therefore, your roof must be in good condition if you want it to last for the life span of your photovoltaic array. Don’t be tempted to skip roof repair if the damage is slight. Small problems can easily grow into big and costly problems over time. And if you need repairs in the future, it will be expensive to remove your photovoltaic array to address the problem. You’ll have to have the solar panels reinstalled, which will cost you even more.

Step Three: Address Roof Obstacles before Solar Panel Installation

Shading can largely affect your photovoltaic array’s output. Roof penetrations like chimneys can result in unwanted shading, and they can also interfere with panel placement. To reap the most solar energy production, it’s important to address these issues now rather than later.

During your roof inspection, ask your contractor to see if any of the roof fittings or penetrations are likely to affect your solar panels. Some, like antennas and satellite dishes, can usually be moved to a better position if needed. Chimneys and vents can be more difficult to move, but may be possible.

Contact us to schedule an inspection to be sure your roof is ready for solar panel installation.

Types of Commercial Roofing Systems

Most low-slope commercial roofing systems have three principle components:

  • Weatherproofing layer or layers — the weatherproofing component is the most important element because it keeps water from entering a roof assembly.

  • Reinforcement — reinforcement adds strength, puncture resistance and dimensional stability to a membrane.

  • Surfacing — surfacing is the component that protects the weatherproofing and reinforcement from sunlight and weather. Some surfacings provide other benefits such as increased fire resistance, improved traffic and hail resistance, and increased solar reflectivity.

If you’re in the process of constructing a new building, or planning the replacement of an outdated roof on an existing building, there are five main types of commercial roofing systems to consider:

Thermoplastic Roofing

TPO roofing systems are among the fastest growing commercial roofing systems. Made of an especially durable material with a low-temperature flexibility and a high-temperature tolerance, these roofs are exceptionally resistant to ultraviolet, ozone and chemical exposure. TPO roofs can be expected to have a lifespan of 20+ years, and also feature a high resistance to fire, punctures, chemicals and high winds.

EPDM Roofing

EPDM roofing offers superior durability and versatility, making it one of the longest lasting types of commercial roofs available. EPDM commercial roofing systems are also typically easier to install, maintain and repair than most other types of commercial roofs.

BUR (Built-Up Roofing) System
A traditional built-up roofing (BUR) system derives its name from the building of a roof on-site using layers of base sheet, interply sheets and cap sheet or other surfacing such as gravel or liquid coating.

Hot asphalt (bitumen) is the bonding and waterproofing agent between layers. BUR is suitable for most low slope roofing applications. The higher the quality of the BUR materials and asphalt used and the greater the number of plies (and separate asphalt moppings), the more superior the roofing system.

APP and SBS modified bitumen
In the 1970s, technological advances in asphalt sciences led to the development of modifiers such as APP (atactic polypropylene)and SBS (styrene-butadiene-styrene) which, when added to unblown (unoxidized) asphalt, impart either plastic (APP) or rubber (SBS) characteristics. These additives provide enhanced performance characteristics to traditional asphalt. When coupled with reinforcements, such as polyester (superior elongation abilities) or fiber glass (high tensile strength), they create high-performance roof membranes.

APP modified bitumen membranes are self-adhering when heated using a roofing torch. SBS modified bitumen membranes can be formulated for torch application, but are more commonly applied using hot asphalt or cold SBS modified bitumen adhesive. The result is a BUR system with significantly enhanced performance capabilities. Continuing improvements in technology have also resulted in self-adhering SBS roof membranes.

When an SBS or APP cap sheet is combined with traditional BUR base sheets and interply sheets, the result is a hybrid roof offering the best of both systems – multiple plies and superior performance and longevity.

Photovoltaic Solar Panels

As energy costs continue to rise and America looks towards green and sustainable energy, many building owners are turning to solar energy roofing systems. PV solar panels installed over a rooftop or used with glass, membrane and roof-mounted tile, absorb sunlight and convert it to energy that can be used to power a building. Although not in wide use, PV panel roofs offer great potential to conserve energy and control skyrocketing costs.

Green Roofs

Perhaps of all the types of commercial roofs available today, green roofing systems have experienced the greatest surge in popularity in the last few years. Sedum green roofs are typically flat roofs that are partially or completely covered with vegetation and soil and planted over a waterproofing membrane. Green roofing systems reduce the urban heat island effect by soaking up heat and also are found to dramatically improve a roof’s insulation value – lengthening the lifespan of the roof by as much as two to three times longer and saving on heating and cooling costs.

All of these commercial roofing systems are excellent choices for industrial, institutional and residential low slope roofing. In choosing, factors such as site access, structural load, finished appearance, desired warranty and performance criteria should all be considered. Your ADCO project manager can help with more information.

Negative Impact of Ponding Water on Roofs

Without proper design, installation, and maintenance, a roof can suffer from ponding water, which can create a variety of adverse effects for the building.

According to the Asphalt Roofing Manufacturers Association (ARMA), ponding water is defined as the water that remains on a roof 48 hours or longer. The ARMA recommends that roof designs provide adequate slope (a minimum of one quarter-inch per foot) to guarantee the roof drains properly throughout the building’s life.

Typical issues that arise from ponding water on roofs include…

  • Accrual of dirt, debris and other impurities, which can mar the roof’s membrane.
  • Distortion of the roof deck’s construction, as ponding water can significantly swell the load. As water gathers, deck deflections can intensify, producing more ponding water that may adversely influence the structural integrity of the deck.
  • The emergence of algae and vegetation. If water is in place for extended intervals, algae and vegetation will probably result, triggering roof membrane damage. Furthermore, these materials can obstruct drains, often causing more ponding.

Ponding water often brings about hastened erosion and weakening of the membrane surface, leading to the roof system’s breakdown. Permitting even comparatively small quantities of moisture under the roof membrane may lower the insulation’s thermal efficiency. Plus, moisture invasion can cause severe impairment to the deck, insulation, membrane, and building interior.

Contact us for more information on how to eliminate the worry of your roof being negatively impacted by ponding water.

 

Why Are Commercial Roofs Typically Flat?

If you look at commercial roofs throughout Southern California (and the rest of the country, for that matter), you will notice that most of them are flat.

Why are most schools, grocery stores, factories, hospitals and other industrial buildings designed with flat roofs? Why aren’t they sloped or peaked like most residential roofs?

If you guessed that cost is the reason, you have only part of the answer.

Flat Commercial Roofs Are Cost-Effective

Yes, budget is a big concern in the design and construction of commercial buildings, particularly since these structures typically have large footprints.

Simply put, flat commercial roofs are cheaper to install because they require fewer materials. Adding peaks and valleys would necessitate a more complex design and result in extra framing costs.

Just like your home, retail and industrial buildings require effective drainage systems to facilitate the runoff of rainwater and melting snow. This increases the cost of the roof, but in most cases, installing a flat roof with a drainage system is still less expensive than any other design.

But commercial buildings don’t have perfectly flat roofs. They may look flat from the ground, but they have a very slight slope (about 2 percent). This prevents water and snow from accumulating, which would add weight to the roof and potentially cause damage.

Steep Slopes Aren’t Practical for Most Commercial Roofing

Building size matters when it comes to designing and constructing a commercial roof.

To design a sloped roof for a large building, the peak would need to be extremely tall or feature multiple peaks and valleys. Neither of those options is practical in most cases.

In addition, building codes in many cities and municipalities impose height restrictions for commercial structures.

Retail and industrial facilities must maximize their square footage, so it doesn’t make sense to invest in expensive sloped roofing. That money is better spent creating usable square footage.

Finally, a peaked roof on a large commercial building is usually unacceptable from an aesthetic perspective. Imagine how strange a familiar “big box” store would look with a tall, sloping roof!

Commercial Roofs Require Space for Equipment

Large commercial buildings require industrial heating and cooling equipment. Mounting this equipment outdoors at ground level is not typically allowed by code, and it can pose a variety of safety and security challenges. While the machinery can sometimes be tucked away in a basement or storage room, that takes up valuable indoor space and may also pose safety, noise or comfort issues.

Flat roofs are the perfect solution, because they provide a secure and remote location for air conditioners, heaters and other types of industrial machinery. Installing these fixtures on a rooftop poses some risks, however, as it leaves the machinery exposed to the elements. Despite this, commercial roof space is typically the location of choice for large equipment.
