Flat & Commercial Roofing in California
Flat and low-slope roofs fail differently than pitched roofs. Water does not run off — it sits, and any low spot becomes a pond that works at the membrane and the seams. Patio covers, additions, and commercial buildings all share this problem, and the fix is a system built for standing water, not a pitched-roof material laid flat.
We install and repair TPO, modified bitumen, and roof coating systems, and we address the real cause of low-slope failure: ponding, tired seams, and flashing at the parapet and penetrations.

Flat & Commercial Roofing — Questions & Answers
Why does my flat patio roof keep leaking?
Low-slope roofs pond after rain, and standing water finds every tired seam and flashing. The fix is a proper low-slope membrane and better drainage, not more sealant.
Do you do commercial buildings?
Yes — low-slope commercial roofs including TPO, modified bitumen, and coating restoration. We scope around your operating hours where we can.
Can a coating save my existing flat roof?
If the membrane is still sound, a reflective coating can extend its life and cut cooling costs. If it is saturated or failing, a coating only buys a little time.
