Asphalt or Built-Up Roof

The most common type of commercial roof is made up of hot asphalt and then most common covered with gravel. There are other types of material as well that don’t require the gravel coating, but if not properly installed can cause improper seals and seams which could lead to leaks and more maintenance. This type of roof is heavier and also helps deflect UV exposure. If using the gravel coating and you can look down on the roof, maintenance on keeping the gravel up to date is something to think about. These types of roofs can last 15-20 years if properly maintained. Our Mighty Watchdog Maintenance Program gives you that peace of mind with data to prove it.


EPDM is made mostly of flat synthetic rubber pieces that are welded together at the seams to form one continuous membrane. This material reflects the UV rays and it resists expansion and contraction. This material is lighter and thinner and attached directly to the decking so gravel or other materials are not needed to hold it down. This type of roof can last up to 25 years if properly maintained.

TPO roofs

Thermoplastic Membranes (TPO)

TPO roofs are usually white which is great to reflect the UV rays and also flame retardant which makes this a great choice for longevity of your roof. Since it can be fully adhered to the decking or mechanically fastened, this type of roof can be very cost effective. TPO roofs can last up to 25 years if properly installed and maintained.
This type of roofing material, modified bitumen, is made from asphalt with a mineral-based surface and many modifiers and solvents. The modified bitumen roofing materials reflect UV rays and also resist expansion and contraction. The application process can be more labor intensive which in turn makes it more expensive. Our Mighty Dog Roofing specializes in consulting on commercial roofing product choices and application processes.
