Commercial Roofing Attachments

(Adco Roofing) Commercial Roofing Attachments

Roofing is typically attached to commercial buildings in one of two ways; full adhesion or mechanically. There may be other methods that you have heard of but these are the most popular ways to fasten a roof. Regardless of the method you use, there will be a layer of insulation beneath the roof and a metal deck below that, which is fixed to the structure below. It is important to understand the differences and to know what your building needs. Failure to match your roofing with the needs can cause you to pay for value that you don’t actually need.

Mechanically attached roofing

Taking up almost 80 percent of the market, mechanically attached roofing is the most popular option for commercial buildings. These systems can be installed quickly and are less expensive. They also have the advantage of being easy to inspect, which means they can quickly be validated by verifying the fastener pattern and their correct installation.

Most buildings have a metal deck, a layer of insulation and then a roof. Installation of a mechanically attached roof involves rolling the membrane down and applying screws directly through the insulation boards into the metal deck. The screws will be driven in at the edge of the membrane and are then covered with the edge of the next sheet to be rolled out. The membranes are heat-welded together to create a watertight seal, and you end up with a flat, waterproof surface with no gaps.

Fully adhered roofing

These roofing systems are glued directly to the insulation layer below it. This means that the insulation boards act to insulate and secure the roof to the metal deck, which requires more screws. This is a more expensive method and more time-consuming. Because large quantities of glue need to be applied at the same time and at the right temperature, this method is more challenging than people realize. Once the glue has dried to form the right tackiness, a roller is used to press the membrane to the insulation.

This roofing option is often chosen because it is thought to be more resistant to leaks. Builders believe that if water was to get through a hole, it would travel under the membrane past the glue. The problem with this is that you will not even realize there is a hole until water has pooled and the glue has become degraded. This causes bigger problems than knowing about a leak right away as the accumulated water can spread and damage a larger area of the roof.

Final thoughts

Fully adhered attachments also provide higher Factory Mutual wind-uplift ratings. These are ratings assigned to commercial properties by a large insurance firm. As beneficial as it is to have these higher ratings, there is really not much need for them in areas outside of coastal or high-wind areas. At this time mechanically attached roofs dominate the market but there is still a demand for fully adhered roofing too. Contact us to determine which roof attachment type will work best for your budget and building.

What Are The Benefits of Reflective Roof Coating?

Reflective Roof Coating

Your building is likely to be the largest investment you make in your life. You need to make sure you protect your investment which includes regular maintenance and keeping the roof in optimal condition. Poor roofing can lead to serious building damage inside and out, which lowers the value, costs you money and ruins your investment. A well-kept building is also the best way to catch someone’s eye should you need to sell in the future.

Benefits of Reflective Roof Coating

The weather in the Los Angeles area can vary throughout the year, but for the most part, we see sunny days. The sun can be your biggest enemy and can take years off the life of your roof. The best way to protect a roof in warm and sunny climates is by installing reflective roof coatings. Even if you have not yet seen any wear and tear, reflective coating is a great way to preserve the life of your roof and saves on future repairs. These coatings create a seamless white membrane which prevents leaks, keeps your roof cooler, and protects from the elements.

The coating can repair any minor damage that your roof currently has and provide future protection. By reflecting the light away your roof will last longer. Keeping the heat away as well as the light also keeps your building cooler, and this means lower utility bills. There are a number of reasons to look into getting reflective roof coatings.

  • A great alternative: Coatings are a good alternative to full replacement which can be expensive. A few leaks or cracks do not mean you necessarily need to replace your roof. A simple coating can take care of this. Have a professional come and inspect your roof to determine if a coating can help you. It will save you money to have minor repairs done and a coating added versus installing a whole new roof.
  • Extended life: By adding a roof coating, the lifespan of your roof will increase by 5-7 years. Your roof will stay leak free and be protected from the harsh sun and other elements for longer, which gives you time to save up for when replacement will eventually be necessary.
  • Saves money: Roof coating costs half the amount of re-roofing. Because the installation of a roof coating is not as invasive or time consuming as roof replacement, you will not lose any business time. By not having to tear the roof off, there is not as much disruption, and less labor required.
  • Lower utility bills: Most roofing materials are dark in color, and in the sun this absorbs heat, making your building hotter. You spend more on air conditioning than you would like. A reflective roof coating will keep the light and heat away, keeping your building naturally cooler and your bills much lower.
  • Tax credit: Coating of your roof can earn you a federal tax credit, where a full re-roofing may not. You could qualify for a 10% credit on the cost of your roof, not including labor costs.

The Reflective Coating Process

Roof coating takes less time than re-roofing. The time required depends on the building size but it typically can take less than a day. Larger buildings may require a few days for completion. Your roof is cleared of all debris first and then the coating is applied. It has to be left to dry for 24 hours but during the time the building can be used, so there is no loss of business time or if a residential home, you can still come and go as you please.


Reflective coatings are the environmentally friendly and economical choice for today. It is a relatively small investment that will deliver big returns. You save on energy bills and reduce the overall maintenance costs that your roof will need. By extending the life of your roof, you get more overall in terms of the investment you made on the whole building. Contact us today for an inspection and we can get started on coating your roof today.

How Your Roofing Choice is Affected by Climate?

How Your Roofing Choice is affected by Climate

We live in a large country and the weather changes in each state from day to day and from coast to coast. Rhode Island could be saturated with humidity while Alaska is in subarctic conditions and Florida is like a tropical rain forest. Regardless of climate, your house or business need roofing that can endure all seasons. It is important to keep the climate in mind when choosing a roofing system and even more important to understand how the weather can impact your roof.

How Your Roofing Choice is Affected by Climate?

Rain, snow, winds and the sun all impact your roofing. Sunshine and extreme heat can cause materials to dry out and crack and humidity can allow unwanted moisture to seep under roofing materials. Winter months are troublesome because snow and ice can build up and ice dams allow water to pool, once any snow begins to melt. Once you have pooled water, leaks can occur into the interior of the building causing rot and mold. Before picking your roof, there are a few things about the weather you should remember.

  • High Winds: Even if you don’t live in a city that is notorious for winds like Chicago, you can still expect high winds from time to time, especially as seasons change. Strong gusts can blow under the roofing materials causing bubbles and wrinkles. This allows moisture to creep in and collect. Once warm weather arrives, you end up with mildew and rot. Winds typically cause damage first around the edges, so be diligent about checking these areas after strong gusts. If you catch the damage early enough it can be repaired easy enough. You can also choose to use fully adhered membranes, which are securely tacked down across every square inch.
  • Wet Weather: The wet or cold seasons bring rain, hail, sleet and snow and even the sunniest states like California are not exempt from some downpours. Sloped roofing allows water to trickle away but flat roofing allows pooling, so need to be more effective at drawing water away. Traditional roofing used tar and gravel, but this came with serious risks, fatal injuries and noxious fumes. As a replacement, roofing companies now choose single-ply membranes for flat roofing and these are not only more flexible but durable too.

When it comes to selecting roofing, knowing the weather in your area matters. Even though the sun can cause damage by drying out materials, the biggest concerns are precipitation and winds. For a seasonal roof that goes the distance, you may want to consider PVC which is durable and lasts up to 30 years. Call us today to discuss your roofing options and we will help you find the best solution for the weather your building has to endure daily.

Commercial Roofing: Flat or Sloped?

Flat or Sloped Roof Commercial Building

Houses typically come with pitched or sloped roofing and commercial buildings are built with flat roofs. Is there something that determines that one style of roof is better for a particular building? As it happens there are a few things to consider when choosing the roof style for any project. Flat roofing offers more usable space which is why it is preferred for industrial projects. If you had a flat roof on your home, just think how much more attic space you would have. Space really does matter and business owners aim to use as much space as they can. This means they can increase storage without the need for offsite storage units which can be expensive.

Commercial Roofing: Flat or Sloped?

In addition to space, many businesses have large air conditioning units to cool the entire building. They may also have other bulky equipment that needs a place and because building codes are very specific, there are limits as to where this machinery can go within the building. All this big, loud equipment can easily be stored on a flat roof, so there is nothing unsightly on the work floor and there is no noise pollution.

As important as space is, money is even more of a priority and flat roofing is usually more expensive than sloped roofing. There are more steps and component involved in the installation and they also require insulation to be included. Depending on the project, the amount of insulation will vary; 1” is needed between an old roof and a new one, but for new construction as much as 5” is required to meet energy code requirements. Insulation may save you money in the long term, but up front, it makes flat roofing more expensive.

Sloped roofs typically last longer than flat roofs because of the sheer assortment of materials that can be used. Wood shingles, concrete, tiles and composition or dimensional shingles all last longer than the materials typically used for flat roofing systems. The weather also takes a greater toll on a flat roof because without the slope to direct water and ice away from the roof, it can build up and cause damage.

Despite the few advantages of sloped roofing, the reality is that commercial buildings are large and would require several slopes, so flat roofing is more efficient. Working on a flat roof is also much safer. Flat roofs also provide perfect spacing and layout for solar panels because they can lay out flat and easily catch the sun rays. Angled solar panels on a sloped roof miss out on the sun at certain times of the day. Flat roofing has one final advantage in that they allow for gardens and recreational space. To keep your current workforce happy and attract new interest, an environmentally-friendly building is the way to go.

Sloped roofing does have its advantages, and when it comes to residential housing, the sloped appearance fits well into a neighborhood setting. When it comes to commercial buildings, however, the need for space, efficiency, accessibility, and maintenance all favor a flat roof. When you can add on the green garden, there really is no other option.

Why Use Membranes Over Tar and Gravel on Your Commercial Roof?

Why use membranes over tar and gravel

When it comes to commercial roofing, tar and gravel system shave been the industry norm for quite some time. They gained popularity after crude oil found a place in the economy and have worked out pretty well for commercial roofing. They are cheap and pretty effective and until recently dominated the industry when it comes to flat roofing systems. Recently, scientific discoveries have found new systems for flat roofing that may prove to be even better than these single ply roofing systems.

Why Use Membranes Over Tar and Gravel

  • Membranes are much lighter. Compared to an EPDM (rubber) roof that has insulation and fasteners with it, plastic membranes are more lightweight. Rubber systems can weigh close to 2 pounds when all is said and done, but modified bitumen or plastic membranes are more efficient thanks to being lighter.
  • Tar and gravel systems involve a hot kettle to melt large chunks of solid tar so there are an inherent danger and high insurance liability. The fumes produced are also very noxious and fatal roofing accidents have occurred in the past with exploding kettles and scorching spills. Because of the risks and dangers, many commercial roofing companies prefer to use membranes instead of tar and gravel and smaller companies are following suit because they cannot cover the insurance policies required to cover the risks.
  • All membrane roof products are available in a white color option. This means the suns light and heat is reflected away, keeping the building interior cooler. When you re-roof with a single ply system it is very easy to first lay down a thick layer of foam board insulation, which helps this system maintain great energy efficiency.
  • When tar begins to age, it shrinks and cracks and because it is essential to the waterproofing aspect of the roof, leaks can occur more frequently. This would be an easy fix except that the gravel often covers the cracks and they are ignored. Additionally, water can run a long way from where it starts so when you notice it, you may have no way of identifying where it started.
  • A built-up roof (tar and gravel) can typically last between 20 and 30 years, depending on how much was spent on it. Membrane roofing systems can last a solid 20 years or longer if not damaged.

The types of membrane roofing systems we install include PVC and TPO. Either of these are great replacements for tar and gravel and will ultimately benefit your commercial building in no time. Contact us today for a consultation and we will help you find the right single ply membrane roof for you.

Roof Inspections as Part of the Selling Process


The condition of your roof matters whether you are selling your commercial building or not. When it comes to selling, however, the roof holds substantial value and any weakness can cost you money. A quick inspection by a professional contractor is the perfect solution. Damage can occur to roofing systems all year round, so regular inspections should be part of your normal maintenance anyway. Even if the roof looks good to you, a professional eye can detect structural weakness or potential problems that could mean lower selling prices for you.

It is important to get your roofing inspected before putting your building up for sale. There are a few key things to remember when looking to get a professional inspection.

What to expect

A professional contractor will check the interior first to identify any structural problems. They will provide you with an accurate and detailed assessment of what is needed to ensure long-term safety and durability. They also evaluate your ventilation, insulation, and moisture as it relates to your roofing. The exterior will then be inspected and checked for shingle damage, leaks and any weather damage. Inspectors also check the flashing to identify any deeper problems in the structure of the valleys, rakes, and eaves. The chimney will also be checked, should you have one to make sure there are no potential issues.

The whole package

An inspection involves an assessment of the structural integrity as well as gutters and they will also look for any rotting areas. Substantial damage can lower the value to the building if it is not deemed fit for long-term sustainability. Nobody wants to buy a commercial building with poor roofing. You want to provide your inspector with as much information as possible. Always choose a bonded and licensed professional for the job because the sale depends on the quality of their assessment.

If a damage is identified, you want to take care of this before listing your building. Hire an inspector to catch repairs before it is too late. Give the roof the attention it deserves and contact us for an inspection today. Our evaluation will help to add value to your building.

Main Benefits Of Installing A Flat Roof

Adco Main Benefits Of Installing Flat Roof

All about the flat roof design

Owning a home by building or purchasing one is probably among the most important decisions that you’ll make in life since that’s a significant project that carries with it a huge monetary value. Not only will it be important because of the financial value involved, but also because a house is at times a lifetime investment that needs to be taken seriously. Generally speaking, you’ll have to consider a majority of your house’s components, if you’re to end up with the house you’ve been dreaming of.

Talking of the parts of that house, one of the major parts to consider will be the roof, which has several factors to consider like roofing styles and techniques. Basically, you’ll have to choose between the flat and the pitched rooftop designs. This article will focus more on the flat roof design, since it’s becoming more popular, not only for office or industrial roofs but also residential roofs.  This means that flat roofing obviously has some benefits that make it the style to choose.

Benefits of using a flat roof

Ease of access

Whenever you need to get to the top of a flat roof, all you may need is a ladder or steps, which in most cases are fixed to the building, so you won’t have to carry climbing equipment around. You don’t require any professional skills to climb and walk on the roof as might be required with alternative designs. This makes it easier to conduct a routine inspection on the roof and helps to maintain better condition of the roof. As the building owner, you could climb to the roof once in a while, conduct an inspection, and identify problems before they even progress. This way, you can call in professionals to get your roof repaired before the damage gets out of hand and more expensive.

It increases usable outdoor space

Do you need to set up some solar panels to save electricity, find a place to relax, or do some gardening? You could do all of this and more, on your flat roof. You can move these items to your roof instead of overcrowding and complicating your backyard. You could even install a green roof comfortably, which can be an excellent way to insulate your home and increase its value.

Increased interior space

If you need more space in your house, you should definitely consider a flat roof, because it has no slopes that “eat up” the interior space. This design would be the best for buildings where the maximum amount of interior space is needed.

Flat roofs are less costly

One thing you will love about flat roofs is that they cost less to install and maintain over their lifespan compared to other styles. Things like labor will even be cheaper since there is less risk involved in installing a flat roof. These roofs are faster and easier to install, resulting in less labor risk and costs. Other than that, these roofs have fewer complications in terms of damage, meaning that the maintenance costs will be lower over time.

Final thoughts

You can conclude that flat roofs are highly convenient when it comes to adding that protective cover to your home. The only challenging task you might have is choosing the best professionals for that job and this is easily solved by conducting some research first.

Commercial Roof Maintenance Checklist

Adco Seasonal Roof Maintenance Tips

Proper maintenance of your building’s roof is essential for the safety of the occupants and to ensure longevity. Extensive damage that is not taken care of can result in structural damage to both the interior and exterior of your building. The best way to avoid these costly damages is to perform annual inspections. You can look over your roof initially to identify any trouble areas, but ideally, you need to hire a professional to thoroughly inspect for serious and underlying problems.

Most people do not realize that much of a roof’s damage comes from the inside so checking the condition of the attic is essential. Make sure all insulation is in optimal condition and repair or replace any areas that need upgrading. Humidity can become trapped in a poorly insulated attic, and this leads to structural damage to the roof and building interior. Adding additional insulation is also a great way to prevent humid air from collecting and lowers your energy bills.

When it comes time to look at the exterior roofing, there are a few key things to look for. Should you notice any problems such as those listed below, contact a professional roofer to come and perform a full inspection. These are troublesome signs that you need to bring to a roofer’s attention right away:

  • Broken or curled shingles, especially around the edges of the roof where they are more prone to lift and wear
  • Buildup of debris along the surface and at the edges or gutters, which can interfere with proper water drainage. Pooled water causes leakage into the interior of the building
  • Look for moss growth which could indicate the presence of rot below the surface
  • Cracking or missing sealant along the vents, skylights and flashing
  • Blistering of materials, which indicates insulation problems as well as material defects
  • Loose, broken or missing shingles will leave exposed spaces and should be repaired or replaced right away

If the repairs are small such as repairing missing or broken shingles, then you can likely handle this yourself. For any more extensive damages or wear, you need to bring in a professional to conduct an additional inspection. Often a complete roofing replacement is needed and this is best left to us. Call us today if you notice any roofing problems and we will perform an inspection and offer the best solution for you.

Commercial Roofing Systems You Need To Know

Types of Commercial Roofing Systems

The only way to get value for your investment and keep your property safe is to find and use the best roofing materials.  There are several things you should know when selecting a roof or changing your current one. Although many will focus on price, there are other features such as the lifespan of the roof, the climate in your area, and maintenance requirements. You can select from the many types offered on the market and get one that best suits your roofing needs.

Commercial roofing systems

It is imperative to know the available roofing systems types when planning to design a new building. The same applies when you have plans to change the roof of your building. You need to familiarize yourself with the three components of each one of them, beginning with the low slope commercial roofing systems.

  • Watertight layers: This is an essential element. It helps to block water from entering the roofing system that could damage and cause it to rot quickly.
  • Surfacing: These components assist in defending and strengthening the watertight seal. It shields the roof materials from sunlight and weather. It also enhances fire resistance and possesses solar reflective properties.
  • Reinforcement: These are components that enhance stability, strength, as well as puncture resistance to the membrane. They are also long-lasting.

Thermoplastic systems

The popularity of Thermoplastic roofing systems is growing fast due largely to their durability. Thermoplastic systems are made from durable materials and have several beneficial properties. These include resistance to ultraviolet lights, ozone, and chemical exposure. Thermoplastic roofing systems are designed to last more than 20 years as they can withstand high temperatures and exposure to harsh elements. The most common thermoplastic systems are PVC and TPO.

Green roofs

Although thermoplastic systems are growing fast in popularity, green roof has had the highest popularity surge. It is likely that the significant increase is due to the benefits it offers, including:

  • Conserves energy
  • Lowers the urban heat island effect
  • Increases the longevity of roof membranes
  • Reduces noise and air pollution

Due to the continuous upsurge in electricity bills, renewable energy is becoming more preferred and  widespread in recent years. Most home owners are using these developments to make sure they have excellent roofing structures such as Photovoltaic Solar Panels. The PV solar boards are utilized to save energy while saving you money. Its key roles are to convert light into energy so that it can light up the house.

Modified bitumen systems

The roofing industry faced further remarkable improvements that transformed asphalt. The advances resulted in the development of SBS (Styrene-butadiene-styrene) and APP (Atactic polypropylene). These are referred to as modifiers. Due to their inclusion, it became easy for builders to benefit from the improvement in the old asphalt roofing structures. This meant installation of industrial roofing with higher performance membranes. There continue to be changes in this sector resulting in further innovative methods that use this technology.

Built-Up (BUR) system

BUR system acquires its name from base sheet built constructions. The roofing systems are constructed from the ground up onsite and include smooth asphalt built-up, either hot or cold, and ballasted asphalt built-up. All types are generally comprised of three parts: bitumen material, ply sheets, and one or more surfacing materials. The type of surface coating used can be instrumental in cost and durability.

EPDM roofing system

This is among the most straightforward roofing systems. EPDM structures are considered superior in terms of permanency, versatility and are known to have a lengthier lifespan when compared to others.

Whether you want to have SBS and APP modifiers, Green Roofs, BUR, Thermoplastic or EPDM roofing, they are all good for commercial roofs. Before you decide, make sure you know the difference between the roofing systems, as this can help you to identify the key benefits as well as any drawbacks that you may encounter after installing them.

The type of the roofing system you choose can contribute a lot and make a great difference in terms of expenditure and first investments. Not only that, but it will create a difference in the cost of your maintenance and repairs. As a building owner, you should consider the cost savings over the years and select a roofing system that works to decrease effects such as urban heat island effect. Protect your investment and the people you love with the best roofing material.

Why Is My Flat Roof Leaking?


It is possible to have residential buildings with flat roofs although flat roofs are mainly used in commercial and industrial buildings. Most people are familiar with pitched roofs as they are typically used in residential buildings. It is important to understand that, although pitched and flat roofs serve the same function, they are different in designs. If your flat roof is leaking, you may have a different problem than if your pitched roof is leaking. There are a few key reasons why your flat roof might be leaking that you should be aware of:

Chimney and exhaust pipe sealant

Since flat roofs are installed mostly in commercial and industrial buildings, these buildings have chimneys to release the gases produced by the heating system. In addition, these buildings have exhaust pipes that allow gases produced by the plumbing system to escape. Chimneys and exhausts require a pipe sealant to ensure they are leak proof but this  can become a weak point. If the sealant is not inspected, maintained and replaced regularly, your roof might start to leak. However, there are modular systems available to seal chimney and exhaust pipes. One of these modular systems is the boot which seals the chimney and/or exhaust pipes for 20 to 30 years. The boot is used alongside a tar sealant which needs to be replaced each year. Its exposure to weather conditions and its age will determine how soon it needs to be replaced.

Maintenance and repair of older roofs

Flat roofs can last long if they are properly maintained over the years. Although they do not require regular maintenance like pitched roofing, flat roofs should not be left unattended for years.  This can allow a problem to develop which means you may end up facing costly repairs. In most cases, flat roofs have gravel added on top of the membrane to provide additional protection. The gravel should be spread out at least once a year because it will become uneven after exposure to strong winds, heavy rainfall, snow, and ice. The gravel should protect the membrane and redistribute it regularly will ensure that your roof lasts longer.

Physical damage

It is possible to have physical roof damage especially due to large hailstorms, wind or if a tree or branches fall on your roof. When this happens, your roof may develop drainage problems depending on the intensity of the damage. You need to hire a professional to assess the degree of damage and determine what needs to be done to repair the roof. You may have to repair the roof but in the event of serious physical damage, replacing the entire roof could be the better option. Physical damage no matter how small can cause leaks, damage to gutters and drains as well as scuppers.

The age of your roofing system may also predispose it a too early deterioration. Most felt roofing systems start to deteriorate after 15 to 20 years, although this varies depending on the materials used, the design and how often the roof was maintained. If the commercial roof of your building is showing signs of leaking or moisture, don’t hesitate to contact a commercial roofing contractor to identify and fix the problem as soon as possible to avoid further damage and costs.
