A flat roof that ponds water is a flat roof with a problem. Standing water degrades membrane material, compresses insulation, and finds every weak point in the system. Twain Harte Roofing & Maintenance solves ponding with tapered insulation that creates positive drainage, minimum quarter-inch per foot slope to drains, scuppers, or roof edges.
Modified bitumen is our recommendation for residential flat roofs and high-traffic commercial applications. Two-ply torch-applied SBS system with a granulated cap sheet handles foot traffic, thermal cycling, and CA UV exposure. It's the toughest flat roof membrane for everyday abuse.
Our Flat Roofing Process
Membrane Assessment
We inspect the membrane surface, seam integrity, flashing condition, penetration seals, drain function, and overall drainage pattern. Core samples reveal whether the existing insulation is dry or waterlogged. Full findings provided in a written report.
Your Options
Based on inspection findings, we recommend the right solution: targeted repair, a coating system, or full replacement. Each option is priced with material specs, warranty terms, and expected lifespan.
Professional Installation
Flat roof installation requires specialized equipment and training. Our crew uses calibrated hot-air welders for TPO and PVC, torching equipment for modified bitumen, and proper adhesive systems for EPDM. Every seam, flashing, and penetration detail gets individual attention.
Final Inspection
Your flat roof gets a completion package: installation documentation, warranty certificates, drainage verification, and maintenance recommendations. We stand behind every flat roof we install in Twain Harte.

Why Choose Twain Harte Roofing & Maintenance for Flat Roofing?
Electronic Leak Detection
We use electronic testing to pinpoint flat roof leaks without destructive investigation. Find the source, fix the source, move on.
Maintenance Programs
Semi-annual flat roof inspections keep your warranty valid and catch problems early. Drain clearing, seam checks, and flashing inspection, all documented.
Core Sampling & Testing
Before recommending replacement or coating, we core sample the roof to check insulation moisture. Waterlogged insulation means tear-off. Dry insulation means options.
