Our Commercial Roof Restoration Process in Portland
Eligibility Inspection & Moisture Scan
A certified Portland restoration contractor inspects membrane, seams, flashings, drains, and penetrations to confirm eligibility. Infrared or electronic moisture scanning identifies wet insulation. This inspection is free and includes a written cost comparison versus full replacement.
Surface Cleaning
The entire roof is pressure-washed to remove dirt, debris, and biological growth. Given Portland's constant rain, moss and algae growth, and wind storms, roofs often accumulate significant contamination that must be fully removed — coatings applied to dirty surfaces fail prematurely and void warranties.
Substrate Repairs
Before coating: open seams are re-welded, membrane punctures patched, failed flashings replaced, wet insulation removed and replaced. These repairs ensure the coating system performs for its full warranted life in Portland.
Coating Application
Silicone, acrylic, or elastomeric coating is applied in 2–3 coats at specified thickness. Seams and flashings receive reinforced fabric embedded in the base coat. Most Portland restorations complete without interrupting building operations.
Inspection & Warranty
Final inspection verifies dry film thickness and waterproof integrity. You receive contractor workmanship warranty and manufacturer-backed coating warranty (10–20 years) formatted for Portland property management files.
