Roofers in Kensington, CA
Roofers in Kensington, CA work on a housing stock that predates modern building codes, scattered across steep hillside lots where water moves in ways the original builders never planned for. Most homes here were framed between 1910 and 1940, and they wear their age in their rooflines: multiple planes, hand-cut valleys, original skip sheathing, and drainage patterns altered by decades of additions. That’s the job in Kensington, and it’s why the work starts with a written price before anything goes up on the roof. Call (361) 320-9467 and we’ll walk you through what your roof actually needs.
Why Kensington Homes Are Different
Kensington is a hillside village that banned commercial buildings in 1915, and that single decision shaped every roof we step onto here. The homes are almost all brown-shingle and wood-sided, built before plywood sheathing and truss engineering became standard. What that means on a roof is original skip sheathing, meaning the boards under the shingles have gaps between them, and valley flashings that were never sized for the water volume a modern storm delivers. On the downhill side of curving lanes like Berkeley Park Boulevard and Amherst Avenue, low-slope valley flashings fail first in heavy winter rain, often because an unrecorded addition upslope changed where water goes. When we inspect a Kensington roof, we’re not just looking at shingles. We’re tracing how water moves across the entire property, including what the neighbor’s drainage is doing to your roof.
The climate does its own work here. Cool, foggy summers keep north-facing shaded slopes damp enough for moss to grow year-round, and the winter rains concentrate from November through March. Summer brings diablo winds, and the Berkeley Hills carry the memory of the 1923 fire into how roofs get built today: Class A fire-rated assemblies and ember-resistant detailing are not optional upgrades in Kensington, they’re the baseline. A 20-to-25-year-old roof on one of these lots is at the end of its natural life, and the pitch, typically 4:12 to 6:12, means water hangs around valleys longer than it would on a steeper modern roof. Every one of those conditions changes how we bid the job, and why the price goes on paper before any work starts.
Our Main Kensington Services
Kensington homeowners call about two things most often: a full roof that has aged past its useful life, and a targeted repair on a valley or flashing that failed during winter rain. Each service has its own page with pricing and specifics.
Roofing Company in Kensington
A full roof installation or replacement in Kensington means tearing off layers that may date back to the original build, then deciding, with the homeowner, what happens with the decking underneath. Skip sheathing from the 1920s is common, and on many jobs we install solid decking before new underlayment goes down. Fire-rated assemblies matter here, and the material choice should be made plainly: GAF, CertainTeed, Owens Corning, and others each have strengths depending on your exposure and pitch. See Roofing Company in Kensington for the full scope, pricing, and what a written quote covers.

Roof Repair in Kensington
Repair work in Kensington is usually about water finding its way in at a valley flashing or a reverse-slope drainage point. During heavy winter rain, roofs on the downhill side of Kensington’s narrow lanes fail first at the low-slope valleys because water backs up faster than the old flashing can move it. We find the entry point, fix it, and document the work in writing. Every repair carries the 365-Day Done Right Promise, and if the repair fails within that year, we return at no charge. Details and repair pricing are on Roof Repair in Kensington.

Roof Inspection in Kensington
A roof inspection in Kensington should be more than a ladder and a glance. Given the hillside drainage, moss on shaded slopes, and the age of the homes here, a diligent inspection checks flashing, decking condition from the attic side where accessible, underlayment, drip edge, and the valleys that carry water around multiple roof planes. It’s a written report of what’s there now and what’s likely to fail next. See Roof Inspection in Kensington for what the inspection covers and what it costs.
