Roofing Contractor in San Rafael, CA

Rea Roofing Inc. works throughout San Rafael, and being equally comfortable on low-slope membrane and steep-pitch work is exactly what this city asks for.

The mid-century flat-roofed homes across Terra Linda, Marinwood and Lucas Valley need low-slope roofing done properly, and they punish shortcuts harder than almost any other house type. There is no attic to buffer a leak — water that gets through the membrane arrives on the ceiling almost immediately, and often on a tongue-and-groove ceiling that is also the finished interior. Drainage design, insulation, and a heat-welded single-ply membrane with properly terminated edges are the whole job.

The hillside neighborhoods bring different problems. Steep lots, roofs that are hard to access, and homes tucked against open space in wildland-urban interface areas where Class A assemblies are required. Sun Valley, the ridges above Dominican and the slopes toward China Camp all fall into this category, and the fire-rating requirement is a genuine design constraint rather than paperwork.

Marin's climate adds moss and debris. Shaded north slopes, redwoods and the fog that pushes in through the gaps hold moisture on roof surfaces far longer than in inland Sonoma or Napa. Moss lifts shingle edges and holds water against tile, and shaded valleys stay damp for months. Roof surfaces here need clearing more often than most homeowners expect.
