Flat Roof Replacement (TPO & EPDM) in San Bruno, CA
Flat and low-slope roofs fail differently than pitched roofs: they live or die by drainage and seams. Our flat roof replacements in San Bruno start with correcting the fundamentals — slope, drainage, and penetrations — then install a modern single-ply membrane (TPO or EPDM) as a fully adhered or mechanically attached system with heat-welded or taped seams.
What This Service Includes
We tear off the failed membrane down to the deck or insulation, address any ponding areas with tapered insulation, replace damaged substrate, and install the new membrane with new flashing at every curb, vent, and parapet. The result is a monolithic waterproof surface with far fewer failure points than the built-up or modified-bitumen roofs it replaces.

- Ponding water that stands more than 48 hours after rain

- Leaks around vents, skylights, or parapets
- An aging built-up (tar and gravel) roof past 20 years
How We Do It Right
We install 60-mil TPO (white, reflective, heat-welded seams) or 60-mil EPDM (black, extremely durable, ideal for certain exposures) depending on the building and budget. Every replacement includes tapered insulation design where drainage needs help, new metal edge details, and a thorough reseal of every penetration. Expect 20 to 30 years from a properly installed single-ply system.
Flat Roof Replacement (TPO & EPDM) for San Bruno Homes
San Bruno's persistent marine-layer fog, salt air, and gusty Peninsula winds are brutal on flat roofs: ponding, UV breakdown, and seam stress. Our replacements correct drainage first, then install membranes engineered for this exposure.

Frequently Asked Questions
TPO or EPDM — which is better for my building?
TPO's white reflective surface cuts cooling costs and its heat-welded seams are exceptionally strong. EPDM has a longer track record and handles building movement well. We recommend based on your roof's specifics, not on what we happen to stock.
Can you fix ponding water during replacement?
Yes — this is one of the best reasons to do a full replacement. We design tapered insulation layouts that create positive drainage to scuppers or drains, eliminating the ponding that killed the old roof.
