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. Tomales Roofing & Maintenance solves ponding with tapered insulation that creates positive drainage, minimum quarter-inch per foot slope to drains, scuppers, or roof edges.
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 Tomales, PVC is the right choice. TPO and EPDM will deteriorate when exposed to kitchen grease venting.
Our Flat Roofing Process
Flat Roof Inspection
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
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.
Professional Installation
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
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 Tomales.
