Whether it's a residential flat section over a room addition, a garage with a flat top, or a full commercial building, Mill Valley Roofing handles flat roofing in Mill Valley with the same attention to detail. TPO for reflectivity, EPDM for budget, PVC for chemical resistance, modified bitumen for foot traffic.
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 Roofing 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
Your proposal includes membrane type, insulation R-value, drainage design, and warranty coverage. If multiple options make sense, we price all of them so you can compare and choose what fits your budget and goals.
Expert Flat Roof Crew
Insulation board cut and installed with staggered joints. Membrane installed over insulation per manufacturer specs. All penetrations (pipes, vents, HVAC curbs) receive custom-fabricated flashing. Drains and scuppers cleared and properly connected to the new membrane system.
Warranty & Drainage Test
Final roof inspection with drainage verification. Warranty paperwork provided. We recommend a maintenance plan to keep your flat roof performing and your warranty valid for its full term.
