Flat and low-slope roofs need a different system from shingles: a membrane such as TPO, EPDM or PVC rubber, a built-up roof, or modified bitumen. They cover garages, porches, additions, commercial buildings and the flat sections of some homes. The roofers below install or repair them.
Ask which membranes each roofer installs and how the seams are joined, how they handle drains and edges where water collects, whether they add insulation under the membrane, and what the membrane maker's warranty and their own workmanship warranty cover.

Ask how the new roof will drain and how it is built to carry snow, and have it looked at after a heavy winter.
Common questions about flat and low-slope roofing
Which flat roof systems do these roofers install?
Each listing page shows which systems that company names, such as TPO, EPDM, PVC or rubber membranes, built-up roofs or modified bitumen. Ask the roofer to confirm which they recommend for your roof.
Can a flat roof be repaired instead of replaced?
Often, if the membrane is sound and the problem is a seam, a drain or a flashing detail. Ask the roofer to check the whole roof and tell you plainly whether a repair will last.
Do these roofers also do commercial flat roofs?
Several do. Check the commercial roofing page, or look for commercial roofing on each listing.
