A low slope roof holds water where a pitched one sheds it, and Pittsburgh metro.
At a glance
- Shingles do not belong on a low slope. Water sits and gets under them.
- Ponding that lasts more than two days is a drainage fault, not weather.
- EPDM is the black rubber. TPO is the white sheet that reflects heat.
- Most low slope leaks are at a seam, a drain, or where the roof meets a wall.

Common questions
How long does a flat roof last
A well installed membrane gives twenty to thirty years. Standing water and foot traffic are what shorten it.
Can I walk on my flat roof
Some membranes take traffic and some do not. Ask before you put anything up there.
