Modified bitumen roof coating extends the life of the torch-down and cold-process roofs you see on so many strip centers and small commercial buildings in O Brien, OR. Mod bit fails slowly. Granules wash off, the asphalt underneath dries out in the sun, and cracks start at the laps.
Asphalt roofs have one quirk that trips up a lot of coating jobs: bleed-through. Oils in the asphalt can migrate up and stain a white top coat brown. We use a bleed-blocking base coat on mod bit to stop that, and it is a step we do not skip.
Before coating, our crew cuts out any blisters, re-adheres open laps, and repairs splits with fabric and mastic. Loose granules get blown off. Then the base coat, then the top coat, built to the thickness the manufacturer specs.
A modified bitumen roof coating in O Brien, OR changes a dark roof into a reflective one and gives the old membrane a new UV shield. If the roof has many blisters or wet insulation, we will tell you, and in that case a coating is not the right fix. For water that sits on the roof, see ponding water repair. Call (833) 441-4944.
