Flat and low-slope roofs rely on membranes and drainage rather than overlapping shingles. The main systems, TPO, EPDM, modified bitumen and built-up roofing, differ in their seams, surface and cost.
- TPO seams are heat-welded; EPDM seams are taped or adhered.
- Standing water shortens a membrane's life, so drainage and tapered insulation matter.
- Compare membrane thickness and attachment method when you compare bids.

From the reference
Flat roofs are standard on commercial buildings and increasingly common on modern homes, low-slope additions, and garages. Choosing the right flat roofing material and contractor is critical — a poorly installed flat roof can fail within years, while a quality installation can protect your building for 20–30 years with minimal maintenance. This guide covers everything you need to know.
Flat roofing has evolved significantly. Modern single-ply membranes and modified systems offer superior performance over older built-up roofing.
