PVC membrane installation in Olympia, WA
Olympia Roofing delivers complete PVC membrane installation for commercial and residential low-slope roofs across Olympia and Thurston County. This single-ply thermoplastic system creates a fully welded, watertight surface suited to the region’s frequent heavy rain and wind events. Homeowners and property managers contact us when existing EPDM or built-up roofs show widespread granule loss, seam failures, or recurring leaks that asphalt options cannot resolve long-term.
Local roofing context
Olympia’s marine climate produces over 50 inches of annual rainfall plus occasional hail and high winds from Pacific storms. Many 1970s-1990s homes and light commercial buildings in the South Capitol, Eastside, and Tumwater areas feature low-slope sections that perform best with heat-welded PVC rather than traditional shingles. Thurston County requires permits for membrane work over 100 square feet; Olympia Roofing handles all plan submittals and final inspections to keep projects code-compliant.
How PVC membrane installation works and who it’s for
Property owners need PVC membrane installation when flat roof sections exhibit ponding water, failed flashings, or insulation damage that allows moisture into the deck. The process begins with tear-off of the old system, followed by deck inspection, new insulation boards, and fully adhered or mechanically fastened 60-mil PVC sheets. Seams are hot-air welded on-site for monolithic waterproofing that resists the constant moisture common in zip code 98513.
