Understanding Differences Among Low-Slope Roof Membranes

Adco-Understanding-Differences-Among-Low-Slope-Roofing-Membranes

When it comes to low-slope roof membranes there are differences you should be aware of. As a building owner, it can be helpful for you to understand the characteristics of the roof membranes on your building. EPDM is the most common membrane and is a black synthetic rubber roof membrane. EPDM roof membrane can be secured in a number of ways. You can use large stones or concrete pavers, known as ballast, to cover the EPDM membrane. The weight of the ballast secures the above-deck roof insulation and roof membrane. If there is no ballast, the system mechanically adheres. A mechanically adhered system has round plates that are aligned a few inches inside the laps in the membrane.

Understanding Differences Among Low-Slope Roof Membranes

You can easily identify a mechanically adhered roof by dragging your foot across the membrane and if it wrinkles in front of the foot, it is likely mechanically attached. These systems more readily show the joints in the cover boards and will likely have plates visible beneath the membrane. EPDM membranes are also typically are joined at the seams with two-sided adhesive tapes. TPO roof membranes are usually white and can be ballasted, fully adhered, or mechanically attached. The vast majority are mechanically attached. TPO membranes have become more common over the past several years and much of this popularity has to do with being thermoplastic. This means the seams are welded together to provide a mostly homogeneous membrane. PVC membranes are similar in appearance to TPO membranes in that they are typically white. They also are thermoplastic but happen to be more pliant than TPO membranes and will conform with substrate changes more readily. If a roof system is not a single-ply roof membrane, then you likely have bituminous membrane, which is asphalt- or coal tar pitch-based. Bituminous membranes typically present as built-up roof (BUR) membranes or polymer-modified bitumen membranes. BUR membranes can be hot tar pitch membranes or constructed using “cold process” adhesives.

BUR roof systems are multi-ply roof systems that are constructed by a roofing crew. BUR membranes usually have one of three surfacings. They are either bitumen and gravel, mineral-surfaced cap sheets or a liquid-applied roof coating. The benefit of a roof coating is to provide reflectivity, ultraviolet protection, and to withstand tough weather conditions. Polymer-modified bitumen membranes usually consist of an unsurfaced base layer of polymer-modified bitumen membrane which is adhered to a substrate and a cap sheet.

The most common methods for installation of polymer-modified bitumen membrane application are hot-applied, which is using hot asphalt, cold-applied which involves using cold adhesives, or torch-applied. Cap sheets can be surfaced with minerals, granules or foil facer, or a protective coating, such as an aluminum coating, over the cap sheet can be applied. Understanding the differences between low-slope roof membranes will help you to make an informed decision when it comes to having roofing discussions with your hired contractor.

Why Should You Hire a Roofer for Your Flat Roof?

ADCO why should you hire a roofer

 

Maintaining the appearance and quality of a flat roof requires regular maintenance. By investing in this, you can ensure that your roof stays safe and can withstand harsh environments and weather conditions. Your roof will naturally age with time, but with regular maintenance and repairs, it will be guaranteed to last longer which protects your investment.

Hiring a Roofer for Your Flat Roof

There are a few key problems you will face with your flat roof, and hiring a roofer ensures these can be taken care of efficiently.

  • Flat roofing is susceptible to ponding. This is when water from rain or melted snow pools in areas of the roof. If this ponding is not corrected right away, it can weaken the roof materials causing leaks and structural problems. Once the exterior is compromised, you may also experience internal structural damage which can be expensive, so you need to contact a roofer as soon as you notice the ponding.
  • Over time, roofing systems can crack along the membrane. Lengthy cracks will appear spongy and are caused after periods of alternating freezing and thawing. An experienced roofer can inspect your roof after each season to identify any cracks or splits and repair them before they spread.
  • Flat roofing typically is layers of substrate and felt, and air can become trapped within these layers. When this happens, the roof can blister which makes it unstable. You can identify blisters as elevated pockets in your roof surface. Call a roofer as soon as you see this and they can remedy the situation and prevent further and more expensive damage.
  • Ridges can also occur when a bituminous buildup occurs within the joints of the roof insulation. This typically happens when moisture condenses under the felt layers. Ridges appear as long, narrow crevices and they most likely can be seen along membranes that are not securely attached.

These issues are common with flat roofing systems, but with regular inspections and maintenance, they can be avoided or repaired once identified. We recommend that you call us to inspect your roof even if you have not noticed any of these problems. With a regular check, we can prevent these problems from occurring before they cause too much damage. Preventative maintenance will be the best way to protect your roof, your building, and your investment.

Tips to Find and Fix a Leak

roof leaking

Roofing leaks are the most common roofing problem as a result of wear and tear or weather changes. Sadly, many people do not realize they have leaks until it is too late. If you notice any water damage inside the building, chances are you have a leak. Tracking the source of a leak can be challenging, so you should call a roofing contractor to help. Once you know where the leak is, repair is not as challenging.

Tips to Find and Fix a Leak

If you think you have a leak, the first place to check is any penetrations, such as vents, ducts, or dormers. These are common places for leaks to start. Check the building for water stains, mold, and black marks. If you notice these, you likely have a leak and need to contact a roofer to inspect the property and repair any damage. Some leaks can be tricky to find. A professional roofer can find these by soaking the roof with water and watching for leaks on the inside. In some cases, the drips or water appear far away from the actual leak. This is common in roofs where plastic vapor barriers are installed within the insulation. A roofer will be able to move this aside and find the smallest leaks that could be hiding from your eyes.

  • Check the vents: Plumbing vent boots can be made from plastic, metal, or both. Plastic can crack and metal seams can open, so the vent boot is a good place to start looking for any leaks. Any broken seams or cracked plastic pieces should be replaced immediately before serious leaks happen. When you are replacing the broken or cracked vent, you should replace all nails with screws as these interfere less with the roofing material.
  • Dormers: Water can leak from above the roofing, especially if the weather is severe. Cracks in windows, dormers, and siding are all possible and will allow water to reach the inside. Before calling a roofer, check the edges with a knife to identify any leaks. The caulk will need to be replaced by a roofer if any cracks are found.
  • Flashing: Most buildings have flashing installed where the walls intersect the roof. Flashing helps to move water away from the roof and with time they can rust, weaken and allow leaking. If you see any damaged or rusted flashing, it needs to be repaired immediately.

Call us today to inspect your roofing and we will help you to find any leaks. We have the experience and skills to get every leak fixed to keep your roof in optimal condition for longer.

Is Your Commercial Roof Ready For The Rainy Season?

Is Your Commercial Roof Ready for The Rainy Season

Is Your Commercial Roof Ready For The Rainy Season?

The rainy seasons can damage your commercial roofing and this damage will be worse and cost even more money if there were pre-existing cracks or tears before the weather gets here. It is important to ensure your roof is repaired and in optimal condition before the rain and snow arrive. Failing to get the roof fixed ahead of time will not only cost you more money but the damage could end up being irreparable. Commercial roofing has a flat design that puts it at greater risk for damage. Cold weather can easily make worse existing cracks and these cracks or tears increase the risk of internal damage as well. Roof repairs are not cheap, but they will definitely be more affordable when done before the rainy season. Protect the value of your building and your investment by ensuring your commercial roof is in optimal condition before the winter arrives.

Prepping For The Cold

Repairs before rain and snow damage are cheaper than a full roof replacement. During the winter, the continuous cycle of water thawing and freezing causes the most damage to your commercial roof. Existing damage to the outer material allows melted snow or rain into the roof and as the weather gets colder, this water can freeze. Water also collects on flat roofing very easily and can freeze into a lake of ice overnight. This additional weight can be too much for your roof to bear. Icy roof lakes can cause serious structural damage and the water that made its way through the cracks into the internal parts of the roof causes further cracking as it freezes and expands. Water that reaches the internal components of a roofing system also causes mold and other interior damage. Ceiling and interior repairs are costly and more challenging than repairing the flat exterior of a flat roof, so you want to ensure all repairs are complete before the weather turns cold.

To ensure that your flat commercial roofing lasts through the winter months, contact a specialized commercial roof contractor to inspect and assess the condition of your roof. We identify any weakness or damage using infrared imaging and we can restore your roof to its original condition so it is ready for whatever the winter has to offer.

5 Things You Need to Know When Replacing Your Roof

(Adco) 5 Things You Need to Know When Replacing Your RoofReplacing a roof is a big decision and requires thought and preparation. There are a number of options for you so you need to research all possibilities to get the best service on your budget. Your roof is susceptible to everyday wear and tear and with changing weather conditions through the year, the damage is likely to occur over time. Before you replace your roof, there are a few things you should consider.

5 Things You Need to Know When Replacing Your Roof

  • Re-roofing: You can decide to re-roof over existing roofing rather than removing the old roof and installing a new one. This is usually cheaper but it can cause additional problems. Heat can build up between the old materials and the new ones, which will create moisture which will build up and may cause serious damage.
  • Measure first: You need to measure your roof first before replacing it to make sure you do not pay any more than necessary. A professional roofing contractor will provide accurate measurements so you only buy the materials that you need. Once you know the measurements you can decide on the material and style you want and chose what fits in your budget.
  • Ventilation: Making sure you have proper ventilation is the best way to ensure that your roof will last. Ventilation helps keep temperatures regulated in the attic area. In the summer, the roof will be cooler and during the winter, moisture cannot build up. Find out what ventilation options are available so you can get the one that will keep your roof in optimal condition for longer.
  • Materials: Many materials go into roofing solutions. There are wood and sealant under rubber membranes and a top material of your choice. Placing new materials over the older underlying ones, without care can cause damage. You need a roofer to inspect the full condition of the roof before replacing it. If the underlying foundations are weakened, the new top materials will be a waste as damage can still occur below.
  • Reputation: For any roofing project, you need to work with a reliable, experienced, and professional roofer. There are many to choose from, so do some research and hire a roofer that has the experience to make sure your roof is installed or repaired correctly. Have a roofer come and inspect the property and provide an estimate before hiring anyone. You can also check reviews from previously satisfied customers to find a quality roofer for the job.

Before investing in an expensive roof replacement make sure you need one. You need to contact a licensed and experienced roofer to inspect the property so they can advise if you need repairs or replacement. We will evaluate your roofing situation and advise the best solutions for your roof and your budget. We can also offer you roof maintenance plans so you can get the most from your roof and delay any needed replacement.

Cover Unsightly Rooftop Equipment with Roof Screens

Many commercial and industrial buildings have equipment on the roof. The roof is an ideal place to keep bulky equipment out of the way and for the most part, out of sight. Depending on where you stand, the equipment can be seen and can look unsightly. Big bulky units can detract from the appearance of your building.

Cover Unsightly Rooftop Equipment with Roof Screens

As important as it is to find space for your equipment, it is equally important to remember that the appearance of your building matters to partners, investors, business prospects, and customers. Your brand and reputation could be damaged by the appearance of bulky roof units. The good news is that you can easily remedy this. Ventilation, heating, and electrical equipment are necessary components of a building, but it is possible to hide them. Investing in roof screens allows you to protect your brand and image, by effectively hiding the unsightly equipment that your building requires.

What Screens Can Hide

Having roof screens can hide equipment from sight, thus protecting the appearance of your building and the appeal of your brand. There is a lot of equipment that can be hidden with the installation of a quality roof screen.

  • Roof Exhaust Ventilation Fans: Roof Exhaust Ventilation Fans are needed to pull dirty air from the building and allow fresh air inside. The bigger your building, the more of these you have, and the uglier your building can look.
  • HVAC Units: HVAC units are typically bulky and lined up in rows, but are necessary for climate and temperature management for the building interior.
  • Cooling Towers: Cooling Towers are used to extract unwanted heat from various places like HVAC units, to reduce the temperature of water. What makes then hard to look at is the rust they are often covered in.
  • Ducts and Pipework: Ducts and Pipework are always associated with HVAC units and other roofing equipment. You can often see ducts and pipes from ground level.
  • Service Walkways: Service Walkways are often used on flat roofing and are necessary for accessing roof equipment. While functional, these are usually located near building edges, so are not that great to look at.
  • Platforms: Platforms are typically part of most types of equipment. Used to raise units from the roof surface, the framework and equipment becomes more visible and when they also have guard rails, they are even more distracting.
  • Communication Systems: Communication systems require antennas, cellular communication units, and satellite dishes. While necessary for communication, these do nothing for the building appearance. You may not be able to hide a tall antenna, but a screen will cover the bulky equipment at the base.
  • Solar Panels: Solar Panels are becoming more popular, so many buildings invest in them. While the panels are not ugly in themselves, the supports, frames, and electrical connections are not pleasant to look at.

The equipment discussed above is necessary and will be a part of any commercial or industrial building. They can take away from the appearance of your property and potentially your image. Investing in roof screens helps to protect your image as they will keep the equipment from sight. There are a number of screen designs and materials available, so you can choose what suits your building and brand best. Consider adding your company logo to the screens for an extra special touch. Reach out to us today to discuss your options and we will find the best screen coverage to protect your equipment and your brand.

What You Need to Know About the California Solar Mandate

(Adco Roofing) What You Need to Know About the New California Solar Mandate

They may not be fun to read, but the building codes and mandates are something that every building owner needs to understand and become familiar with. The more you understand, the better you can maintain your buildings and protect your investments over time. They also help keep your buildings up to code, which will bring you more success in the long term. The 2019 Building Energy Efficiency Standards are designed to get California into solar power without inconveniencing too many people. The main points you need to know are discussed below.

What You Need to Know About the California Solar Mandate

The time to recoup money spent on solar installation has been a time-consuming challenge for building owners, and the process is still not a cheap one. The California Energy Commission (CEC) estimates that new construction of an up-to-code building will increase by $9,500 but you will save $19,000 on energy and maintenance costs. On top of this, if multiple buildings are constructed within the same neighborhood, labor and transportation costs can be combined which will lower the per-unit installation cost.

  1. It is important to understand that not all buildings are covered by the new solar mandate. Multi-family homes fewer than three stories in height are included. Industrial, commercial and high-rise residential buildings are not. There are also new climate-zone specifics to be enforced which state that common areas in all multi-family buildings are not included in the sizing calculations for energy usage that gets compensated.
  2. Multi-family developments and builders will now need to consider solar installation on any new projects. Previously, there was not much incentive for this, but now owners can include solar power so installation and maintenance will need to be factored into rental prices and planning costs. There may be resistance when it comes to renters not wanting to cover the increased costs with solar power. Owners have to be creative when accounting for solar system needs and time to recoup the costs to keep everyone happy.
  3. The ‘duck curve’ charts energy usage throughout the day compared to energy generation. During the day the potential for generation always exceeds the demand and in the evening more energy is needed but less is produced. This updated mandate includes compliance credit to reduce the impact of this curve. The installation of batteries during the day allows power to be stored during times of high generation and used later when demand is high, but little energy is being produced.
  4. Solar systems will lose functionality without proper maintenance so customer education will be critical for this. The new code includes that it is now mandatory that an update to the building owner be provided as to how the system is operating. These updates need to be completed and the builders of these new solar-powered buildings must include warranty and maintenance costs in their plans.
  5. Since not all buildings are the same, flexibility is important. The idea is to use community solar and not individual rooftop units, and by having a single solar garden, labor costs can be reduced. However, the tenants will not benefit from net metering of this solar arrangement. There are also rules in place stating that if a roof can not sustain solar panels for any reason, builders have the option of trade-offs and storage credit to consider.
  6. Local authorities have the ability to make codes more stringent, so you should always refer back to them when you want to build. If they are able to demonstrate that changes to the code will reduce energy consumption the CEC will allow their changes to be made. This is great in terms of flexibility but it means that you need to verify all designs with local authorities to make sure any changes have been incorporated into your design.

Final thoughts

These are the main points of the new mandate and there are more details available in the full 2018 California Solar Mandate code. Understanding the new solar changes coming into place will be essential for your success.

If after plenty of research, you’ve determined that you want to invest in solar panels, don’t start researching solar installers just yet. First, we suggest checking to make sure your roof is as ready for a solar panel installation as you are. There are three main factors you should consider:

  • The age of your roof
  • The roofing material
  • Possible obstacles for the solar panels

If you’re not sure whether your roof is ideal for solar panels, give us a call and we’ll evaluate the condition of your roof at no charge.

Tax Cuts on Re-Roofing Projects

(Adco) Tax Cuts on Re-Roofing ProjectsBuilding maintenance is not cheap but is always necessary. Owning a building is a huge investment and you are responsible for maintaining the integrity of the building at all times. Regular service, maintenance, and improvements are needed to do this and the costs of these add up. Taxpayers can breathe a sigh of relief now, as changes to the Tax Cuts and Jobs Act expanded its definition of qualifying property, giving individuals a chance to expense more of these maintenance costs.

 

 

Tax Cuts on Re-Roofing Projects

The Tax Cuts and Jobs Act of 2017 recently expanded the definition of qualified property that will be eligible for full expensing. Under section 179 of the tax code, qualified properties can include improvements to non-residential roofing projects as eligible for tax cuts. The information below can help you to determine if your company is eligible for this preferential tax treatment when you make improvements or upgrades to your nonresidential roofing.

What is Section 179?

This section of the tax code allows taxpayers to expense the costs of qualifying property immediately rather than having to recover it over several years of depreciation. There has been a significant increase in expensing limits with the maximum amount now being $1 million. Additionally, there is a phase-out threshold of $2.5 million. These limits are effective only for qualifying property that is placed into service during taxable years after December 31, 2017.

Roofing is Now Qualifying Property

Improvements to roofing of non-residential property is now included in the definition of qualifying property along with heating, ventilation, fire protection, alarm systems, and air conditioning. With this expansion of the definition, taxpayers can now include roofing upgrades and improvements and can choose to fully expense the costs of the work done. This can include full re-roofing projects. All costs for these qualifying projects can now be expensed in the year of purchase by any taxpaying individual that is eligible to deduct expenses under Section 179 of the tax code. If you have any questions you should contact your tax professional. Find out if your company is eligible to start enjoying this more favorable tax treatment, and start saving money today.

The Importance of Roofing Insulation

(Adco) The Importance of Roofing InsulationThe insulation of a roof is just as important as the outer material. Insulation is important to the longevity of your roofing system and has been used for centuries. Over the years, insulation has changed and adapted, but its purpose is the same; keeping heat inside when you need it and outside when you don’t.

The Importance of Roofing Insulation

Insulating the roof of your building saves you money every year. By controlling the internal building temperature insulation saves the need for energy. You no longer need as heating and air conditioning. Insulation reduces the amount of energy needed to run the building. Using less energy means you are keeping money in the bank and protecting the environment by leaving behind a smaller carbon footprint.
Roofing is exposed to more environmental pressures than any other part of the building, especially weather. Rain, snow and sun exposure wears away roofing and can cause damage which interferes with insulation and energy savings.

To get the best insulation for your roofing system, you should speak with a professional roofer. This way you can get the best fit for your building and the local weather. There are a few choices for insulation including polyisocyanurate, EPS (expanded polystyrene), HD coverboard, fiberboard, and tapered. HD coverboards are the best options for snow and tapered works best for rainfall. Preventing water from pooling prevents dangerous leaks and damage to the building interior.

Reflective roofing is also a popular choice for areas with high sun exposure. However, reflective roofing and insulation can benefit your building in all seasons. Regardless of the outside temperature reflective coating and insulation can help heat to escape the inside, where temperatures can rise due to machines and equipment. Temperature control is the best way to keep costs down and keep building occupants comfortable.

Conclusion

Insulation installments have increased dramatically over the last 5 years and in many states, insulation is part of building codes and is required. Any new building must have insulation installed. Roofing projects are expensive so many people think of insulation as an option and choose against it. With it being important to energy savings, and as part of many building codes now, insulation is clearly more than an option. Contact us today to discuss your insulation options so we can get you saving money and energy right away.

How To Inspect Your Commercial Roof?

How to Inspect Your Commercial Roof

The roof is a valuable part of your building. It does more than just protect you from the elements; it also adds value to your home. A poorly installed or maintained roof can damage the overall value to your building as well as damage the property. Your roofing system is an investment, so it is important to maintain it regularly and schedule inspections and repairs as necessary. The number of repairs or upkeep you need to perform will depend on the quality of the initial installation, the quality of the materials, and the weather the roof is exposed to. It is important to understand the different materials available for roofing. Depending on the material of your roof, you can have a better idea of what potential problems may occur. When you know what to look out for, you can take better care of your roof.

Roofing Materials

  • Asphalt: This is the most common material used because they have a long lifespan and are easy to install.
  • Metal roofing: Now offered in recycled version, metal roofing is becoming more popular. Copper, aluminum, and steel are most commonly used and all are lightweight and durable. Metal roofs are resistant to harsh weather changes. Check often for dents and scratches to identify damage.
  • Clay or concrete: Tiles made from clay or concrete offer long lifespans are energy efficient and very durable. The extra weight of the tiles can be a burden on roofing structures, so proper installation is necessary.
  • Wood shakes: These are classic and beautiful in appearance but also high maintenance. Wood can crack easily so be sure to check often for signs of cracking and rotting in the event moisture does seep through any cracks.
  • Thermoplastic membranes (TPO): – TPO involves the use of a roofing membrane that expands and contracts as the weather changes. These types of roofs do not have any negative impact on the environment, and do not degrade under UV radiation. These membranes are available in a variety of colors. White roofing material is highly recommended in areas with high temperatures because it reduces the heat island effect and solar heat gain in the building.
  • Thermoplastic membranes (PVC): – PVC sheets contain plasticizers and stabilizers, as well as other additives to impart flexibility and achieve other desired physical properties. Some membranes are available with nonwoven fleece backing adhered to the underside of a sheet.

How To Check The Roof?

If you think it may be time for a roofing inspection, then you should first conduct your own before bringing in a professional. On average, inspections are recommended twice a year because the weather can change and cause damages. Ideally, you want to look over your roof before and after the typical wet season for your area. Check for obvious signs of wear after cold spells such as curling around the roof edges. Shingles that have become brittle from cold weather will have surface cracks and bubbles that can indicate ventilation issues.

Make sure you walk around the entire building and check the top, sides and insides sections of the roof. Look inside the attic space for any leaks or interference to the ventilation system. When your attic has ventilation issues, you reduce the overall lifespan of your roofing system. You also need to check all gutters and downspouts because if these are clogged, you risk water buildup on the roof surface and increased the chance of leakage. Checking the gutters after heavy rainfall is advised in the event any clogs developed.

During your inspection, should you notice any issues with dampness or moisture, you are better off hiring a professional to take a look. It is not advised to take your roof apart to identify the problem. You could cause more damage if you are not trained to identify the source. Professional roofers use three techniques to identify moisture in your roofing system:

  • Infrared scans: the scans are used to detect if any heat is being lost and how much. In doing, so they can identify areas of moisture and leakage.
  • Nuclear isotopic meters: This scanner identifies hydrogen atoms, and as hydrogen is the main component of water, the more that is found, the more chance of a leak you have.
  • Electrical resistance: Since water is highly conductive if your roof is acting like a good conductor, it likely has a leak and water buildup.

Conclusion

Professional roofing contractors are better trained and equipped to identify a number of potential problems. We can then offer the best maintenance solutions for you or a new installation plan that will solve problems and extend the life of your roof and house.
