Commercial Roofing Contractor in Seattle
A leak over a store floor, a server room or a tenant’s unit can’t wait. We keep flat and low-slope roofs around Seattle watertight through the months of rain.
Commercial roofing for Seattle buildings
When a commercial roof leaks, it’s inventory, equipment and tenants on the line. As a commercial roofing company we work with owners and property managers on commercial roof repair, upkeep and full commercial roof replacement.
Flat roofs in a wet climate need drains, scuppers and seams that work every week from October to April. Clogged drains, ponding water and debris are where most commercial leaks we look for begin.

Flat roof repair, replacement and installation
Flat roofing has one job in Seattle: move months of rain to the drains before it finds a seam. Most flat roof repair we do starts at a clogged drain or scupper, a lifted seam, a blister or a spot where water ponds for days.
Commercial flat roof repair usually means opening up the failed area, drying it out and patching with matching membrane. When the membrane is worn across the whole roof, flat roof replacement with new insulation and taper to fix the ponding is the better spend, and flat roof installation on new buildings and additions follows the same rules.
Commercial roofs kept watertight through the rainy season, with honest advice on repair or replacement.

Often. After an inspection we tell you straight whether repairs or a coating will buy more years, or whether replacing is the better spend.
