Used on a wide array of commercial flat roofs, from warehouses, to restaurants, offices, medical, industrial, etc. Anytime there is a flat or low slope roof, EPDM, TPO, or PVC is a great option.  

EPDM (Ethylene Propylene Diene Monomer) - EPDM is cheaper than PVC, and it has a longer, more successful track record than TPO, but it is not quite as strong. We typically prefer PVC or TPO on these flat roofs.

PVC (Polyvinyl Chloride) - While PVC is a little more expensive than TPO and EPDM, it tends to be more durable and lasts longer.

TPO (Thermoplastic Polyolefin) - This is one of the most widely used roofing materials in the industry, and it is also the least expensive. If price is the #1 consideration, this is a good option. It isn't as strong as PVC, but it is still better than EPDM.

Modified Bitumen

This is asphalt roofing application, again used on the flat and low slope commercial/industrial roofs. There are several different applications of this product, from torch-down, to self-adhesive and more. It is a very durable roofing application and can provide many advantages of durability and longevity, though sometimes it becomes hot due to its dark color, and can raise the temperature of the building and thus weaken the roof over time. But coating it with a UV protectant is also another viable option to prevent any UV damage. 

Standing Seam Metal

Metal roofs are some of the strongest and most durable in the industry. It can withstand a wide array of bad weather, from strong winds, to hail, flying debris, fire and even some can withstand tornadoes. For commercial buildings with sloped roofs and residential houses, metal roofs are an aesthetically appealing and very sturdy roofing solution. 


Tile roofs are both durable and beautiful, and can be a great architectural addition to any commercial, or residential building. There are many different types of clay, concrete, and even metal tile shingles that are popular, and some tile roofs can last up to 75-100 years.

Liquid Coatings

Roof coatings can be applied to a variety of roof types to protect and seal the underlying roofing material, help stop and prevent leaks, and limit future weathering. They are designed to move with your roof and be more forgiving rather than remain rigid, which makes them especially durable. Some coatings are also designed to cool the building.

Roof coatings can be used on many industrial and commercial roof types such as metal roofs, concrete roofs, bitumen, modified bitumen or BUR roofs, EPDM roofs, or as a sealant over new PUF roofs.
