Flat roofs don't drain like sloped roofs. Water sits instead of running off. That fundamental difference means flat roofing requires specialized materials, installation methods, and drainage solutions. Mill Valley Roof Repair installs and repairs TPO, PVC, EPDM, and modified bitumen flat roofing systems throughout Mill Valley.
PVC membrane is the only flat roofing material that resists animal fats and chemical exposure from rooftop grease exhaust. If you own a restaurant or commercial kitchen in Mill Valley, PVC is the right choice. TPO and EPDM will deteriorate when exposed to kitchen grease venting.
Every flat roof Mill Valley Roof Repair installs includes proper drainage design. Tapered insulation, cricket saddles around rooftop equipment, and properly sized drains or scuppers ensure water moves off the roof, not into your building. Ponding water voids many manufacturer warranties. We eliminate it.
Our Flat Roofing Process
Free Evaluation
Our inspector checks every detail: ponding areas, seam separations, flashing failures, clogged drains, UV degradation, and blistering. Core samples test insulation moisture content. You get photos and an honest assessment.
Your Options
We present options, not ultimatums. If a repair extends your flat roof 5-10 years, that might be the smartest investment right now. If the insulation is waterlogged and the membrane is failing, replacement is the answer. We lay out the facts.
