We diagnose flat roof leaks by membrane type first, since a TPO seam fix and an EPDM patch use completely different materials and methods.

These are the specific reasons Sonora customers pick us for Flat Roof Repair work over a general handyman or an out-of-town crew.
We match the repair method to the actual membrane installed, not a generic patch approach that works on none of them well.
Ponding water accelerates membrane failure over time, and fixing the drainage issue often matters more than patching the symptom.
Commercial flat roof repairs get scheduled around your operating hours whenever possible, minimizing disruption to tenants or business activity.
We use water testing and seam inspection to confirm the actual leak source before cutting into a membrane, since flat roof leaks often travel before showing up inside.
Every category below is handled by our own Flat Roof Repair specialists, not a generalist crew or a subcontractor, which keeps the diagnosis and the fix consistent.
Heat-welded patches and seam repairs restore the membrane's watertight seal using the same welding method as original installation.
Adhesive-seamed patches and seam tape repairs address punctures and failed seams on EPDM rubber membrane systems.
Repairing modified bitumen requires matching the original application method, torch or cold-process, for the patch to properly bond.
Tapered insulation or additional drains get added where standing water is accelerating membrane wear.
Roof penetrations, vents, HVAC curbs, drains, get resealed or reflashed where membrane separation has opened a leak path.
Where damage exceeds what a patch can address, a full section gets replaced and welded or seamed into the surrounding membrane.
