APP and SBS Modified Bitumen Roofing
Modified Bitumen Roofing uses modified bitumen membrane roofing sheets made of asphalt.
They are either modified with plastic (atactic polypropylene or APP) or rubber (styrene-butadiene-styrene or SBS)— ensuring more flexibility, durability, and longevity for your roof.
If you’re looking for a roofing material that is uniform and has a vast temperature range, then modified bitumen might be for you.
We here at Sam’s Roofing Materials carry APP and SBS modified bitumen roofing materials that we think will be perfect for your roofing needs.
