Professional flat roof repair for Mercer Island property owners. Lapolla Industries delivers lasting results with industry-leading SPF technology.
Flat roofs in Mercer Island, WA fail at predictable points: seams, flashings, penetrations, and areas where water ponds. Lapolla Industries diagnoses the specific failure mechanism on your roof using infrared scanning and visual inspection, then applies a targeted repair that addresses the root cause — not just the symptom.
In Mercer Island, WA, the difference between a spray foam job that lasts and one that fails comes down to the contractor. Lapolla Industries applies the same quality standards to every flat roof repair project that earned us a reputation as one of the nation's most trusted SPF specialists — proper surface prep, correct foam thickness, and factory-specified coating application.
Every flat roof repair project we complete in Mercer Island is backed by both manufacturer material warranties and our own workmanship guarantee. We document every step with photos and measurements, provide you with a detailed project report, and remain available for warranty service and maintenance throughout the life of your SPF system.
Our proven process ensures quality results on every spray foam project.
Our assessment process goes beyond a visual check. We examine substrate conditions, drainage patterns, existing insulation performance, and structural integrity. This data-driven approach ensures we recommend the right spray foam solution for your specific property.
Our preparation process includes substrate inspection, cleaning, moisture testing, and priming. We mask all areas not receiving foam, set up containment where needed, and verify that temperature and humidity conditions are within specification for application.
Our factory-trained crews apply spray polyurethane foam using calibrated equipment that ensures consistent thickness, proper density, and complete coverage. The foam expands on contact, fills every gap, and bonds permanently to the prepared substrate.
The final step is applying a protective topcoat that shields the SPF from UV exposure and provides the weather surface. We select the coating type based on your roof slope, ponding conditions, and desired service life. After coating, we clean up completely and review the finished project with you.
