Mountain flat roofs are rare (most mountain homes are pitched). Where present (mostly detached accessory structures), modified bitumen handles snow load better than single-ply TPO.
How long does a TPO roof last?
Properly installed TPO lasts 15–25 years in San Diego. UV and thermal cycling are the main aging factors. White (reflective) TPO lasts longer than colored. Proper drainage is the single biggest factor — ponding water cuts TPO life in half.
Why does my flat roof have ponding water?
Two reasons usually: incorrect slope at install (code requires 1/4 inch per foot minimum toward drains), or deck sag from age and weight. Ponding accelerates membrane breakdown and is a code issue. We assess during inspection and correct slope with tapered insulation during replacement.
