About flat and low-slope roofs
Flat and low-slope roofs do not shed water the way a pitched roof does, so the membrane and its seams do all the work. The common choices are TPO and PVC single-ply membranes, EPDM rubber, modified bitumen, and coatings that extend the life of a sound roof. Ponding water, blocked drains and failed seams cause most leaks. A flat roof needs a look every year or two.
What to ask a contractor
- Which membrane do you recommend for my roof, and why?
- How will you deal with ponding water and the drains?
- Are the seams heat-welded or glued, and how long is the seam warranty?
- Can the existing roof be coated instead of replaced?
