Commercial Roofing Materials Explained

If commercial roofing is done right, you won’t have to worry too much about it. But it’s always good to know that you’re getting the best value for your money. Here is a quick list of the most common commercial roofing materials and how they work.

Built-Up Roofing

This type of roofing takes a layered approach to insulation. More layers mean better protection against extreme temperatures and moisture. Its name comes from the fact that roofers build up layers of felt and bitumen before laying down a surface layer.

Bitumen is a powerful adhesive, but modified bitumen is a mixture of bitumen and asphalt. It is an even stronger adhesive than regular bitumen alone.


EPDM is a rubber roof coating that roofers lay down in strips. It comes in rolls, and is very tough. It is actually like a protective membrane. The seams between rows are covered by waterproof tape or another material that is waterproof.


Thermoplastics (PVC and TPO) keep your roof very safe from storm damage. They are similar to EPDM in application, but its seams are welded instead of taped.
