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. Snoqualmie Roofing & Maintenance solves ponding with tapered insulation that creates positive drainage, minimum quarter-inch per foot slope to drains, scuppers, or roof edges.
Our Flat Roofing Process
Membrane Assessment
Before recommending repair, coating, or replacement, we inspect the entire flat roof system. Membrane condition, insulation integrity, and drainage patterns all factor into our recommendation.
System Recommendation
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.
Expert Flat Roof Crew
Our flat roof crew installs per manufacturer specifications and NRCA guidelines. TPO seams hot-air welded and probe-tested. Modified bitumen torch-applied in two plies. EPDM fully adhered with proper lap adhesive. Tapered insulation installed to create positive drainage.
Warranty & Drainage Test
After installation, we verify drainage by checking water flow to all drain points. No ponding. Every seam tested. Manufacturer warranty registered, 15-20 year coverage depending on system and build-up.

Why Choose Snoqualmie Roofing & Maintenance for Flat Roofing?
Drainage Solutions
We solve ponding water with tapered insulation systems. Minimum quarter-inch per foot slope to drains or edges. Ponding is the number one flat roof killer. We eliminate it.
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.

Flat roofing requires different skills and equipment than sloped roofing. Our flat roof crew does this work every week, hot-air welders, torch kits, and adhesive systems are their daily tools.

About Our Snoqualmie Flat Roofing Services
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 WA UV exposure. It's the toughest flat roof membrane for everyday abuse.
Roof coatings can extend the life of an existing flat roof by 10-15 years for a fraction of replacement cost. Silicone coatings over TPO, EPDM, or metal work well when the existing membrane is still in decent condition. We core sample and moisture scan to make sure coating is the right call before recommending it.
