Flat Roof Repair
Flat roofs that hold standing water long enough will rot the deck beneath them. We diagnose the drainage problem, repair or replace the membrane, and waterproof parapets and all penetrations — not just the visible wet spot.
Flat roof failures are almost always a systems problem, not a single point of damage. Alliance investigates the full drainage picture: parapet height, scupper sizing, internal drain condition, and membrane seam integrity. We repair or replace EPDM and TPO membranes, re-flash parapets and curbs, and can add tapered insulation to correct chronic ponding situations. We document everything with photos before and after.
