Types of Commercial Roofing

Commercial Roofing Downingtown PA plays a vital role in protecting businesses, investments, and people from the elements. The roofs of commercial buildings are a complex mix of materials and installation methods.

There are many types of commercial roofs, but shingles, TPO and PVC membranes, and seamless elastomeric coatings are among the most popular choices.

Single-ply membranes


Single-ply membranes are a durable and cost-effective solution for commercial roofing. They are lightweight, long-lasting, and can resist harsh challenges such as intense UV rays, high winds, chemical residue, and thermal shocks. With proper installation and maintenance, they can last for decades.

These systems are available in a variety of styles, materials, and technologies depending on your needs. The most common types are polyvinyl chloride (PVC), thermoplastic polyolefin (TPO), and ethylene propylene diene monomer rubber (EPDM). PVC is a popular choice because it has reflective properties that can help reduce air conditioning costs, as well as resistance to chemicals, flames, and water. TPO and EPDM are also durable roof membranes with heat-weldable seams.

However, as with any roofing system, it’s important to read the manufacturer’s warranty carefully before committing to purchase and install one. There are usually two separate warranties: a manufacturer’s warranty on the roofing membrane, and a labor and installation warranty that covers any issues that arise during the project. The labor and installation warranty should be issued by the roofer who installed your roofing system and will typically include a detailed checklist of what is and isn’t covered.

While it’s true that some sharp objects can puncture single-ply membranes, regular inspections and maintenance should curb this problem. It is important to check the condition of the membrane, including the seams and attachment points. If you notice any signs of damage, like blisters or shrinkage, these should be addressed immediately.

In addition, many single-ply membranes are made to be resistant to certain chemicals, making them an excellent option for a commercial building with a chemical processing plant or similar facility. This durability means that you’ll save money on frequent repairs and replacements, and the roofing system will remain in good condition for longer than many other roofing options.

Although there are a number of benefits to using single-ply membranes, it’s crucial that you consult with a roofing professional before making a decision. They can guide you to a roof that will best suit your business’s unique requirements and climate conditions. They can also explain the differences between these different roofing systems, and which will offer the most value for your business.


Shingles are commonly used in residential roofing, but are also a popular choice for commercial roofs. They are attractive and durable, and come in many different styles and colors to match any business. These roofs are usually less expensive than other roofing materials, making them an excellent choice for businesses looking to upgrade their appearance without spending a lot of money.

When selecting shingle roofing, it is important to consider the type of weather in your area. High winds, heavy rains, and frequent hail can shorten the lifespan of a shingle roof. Additionally, hot temperatures can cause the shingles to break down. If you are considering a shingle roof, be sure to invest in high-quality shingles, and have it properly installed by a professional.

Asphalt shingles are the most common shingle type used in commercial roofs. These are a good choice for most commercial buildings, as they are easy to install and maintain. The most common type is the three-tab shingle, which has an agreeable price point and requires minimal maintenance. Other options are architectural shingles, which have a more unique look and offer a longer lifespan.

These shingles are thicker and have more layers, making them more durable and wind-resistant than three-tab shingles. They can be more expensive, but they can also have lifetime warranties from the manufacturer. If you are planning to use a shingle roof in an area with high temperatures, heavy rainfalls, or frequent hail, it may be worth the investment.

It is also important to note that shingle roofs aren’t suitable for every commercial building. They can’t support the heavy equipment that is often used on commercial properties, and they aren’t designed for low-slope roofs.

If you are interested in using shingles on your commercial property, be sure to contact the experts at GSM Roofing.

Metal is a durable and affordable material that can be used in a variety of commercial roofing applications. It is available in many colors, styles, and materials, including copper, aluminum, steel, and galvanized tin. MBCI metal roofs and wall panels can be customized with exposed or hidden fasteners to suit different architectural styles. These options provide a visual aesthetic for the building while providing durability and low maintenance costs.

Stainless steel is another option for commercial roofing, especially in hotter climates. It can effectively reflect thermal temperatures away from a building, which reduces cooling costs and energy usage. Stainless steel is also durable and can last for 60+ years, making it an excellent choice for a commercial roof.

The upfront cost of a metal roof is higher than traditional roofing, but the service life of a metal roof far exceeds other types of commercial roofing materials. In addition, the longevity of a metal roof reduces overall building expenses by eliminating maintenance costs and repairs. Additionally, the material is fire resistant, and the insulation can improve energy efficiency in a building.

There are a variety of different types of metal roofing, including EPDM (Ethylene Propylene Diene Monomer) and TPO (Thermoplastic Olefin). These types of commercial roofs offer durability, versatility, and resistance to extreme weather conditions.

Other types of metal roofing include standing seam and corrugated metal. Standing seam metal is made from rolls of metal that are joined together, creating a seamless surface. This type of metal roofing is often installed with concealed clips, which eliminates the need for drilling holes into the surface of the building.

Corrugated metal is a popular choice for flat or low-sloped commercial roofs because it allows water to drain quickly. It is also highly durable and can withstand high winds and other extreme weather conditions. It is also lightweight, reducing the burden on the structural structure of the building. However, this type of roofing can be difficult to install correctly. It requires extensive expertise to ensure that the roof is protected from water and wind damage. In addition, it is important to choose the right thickness of the metal for your project.

Seamless elastomeric coatings

Elastomeric roof coatings are a combination of different products mixed into one compound to create an extremely strong and durable roofing material. They are typically used to cover existing roofing materials and protect against moisture, sunlight, fungus, wind, debris, and other environmental elements. They are also highly versatile and can be applied to flat or sloping surfaces. This makes them an excellent choice for a wide range of commercial roofs.

In order to work, these types of roof coatings must be applied to a clean and dry surface. This is why the experts at TRICO PAINTING recommend regular inspections of your home or managed HOA property to identify and repair cracks in the elastomeric coating. It is important to follow the manufacturer’s recommendations for preparation to ensure that the product will offer proper protection.

Once the elastomeric roof coating is fully dried and cured, it will be extremely durable. This type of roof coating is able to expand and contract with temperature changes, so it will not crack or break as easily as traditional roofing materials. This flexibility also helps prevent leaks and reduces the need for frequent repairs.

There are three main types of elastomeric roof coatings, and each has unique properties that make it a great option for different kinds of roofing structures. Acrylic elastomeric coatings are very popular due to their low cost and versatility. They are easy to clean and provide good insulating properties. They are also resistant to algae and fungus. However, they are not as water-resistant as other elastomeric roof coatings.

Silicone elastomeric coatings are more expensive than acrylics, but they offer greater impact resistance and can withstand ponding water. They are also more resistant to weathering, making them a great choice for steep-sloped roofs.

Urethane elastomeric coatings are the most durable of the three types, and they can resist even the most severe weathering conditions. They are not as flexible as silicones, but they are still much more durable than acrylics and silicones.

No matter which type of elastomeric roof coating you choose, it is crucial to have it properly installed by an experienced contractor. The right application method will ensure that the roof coating offers maximum durability and will last for many years.
