We’ve been climbing Kensington roofs since 1984. We know the 10/12 pitches off Arlington Avenue, the dormer valleys near Blake Garden, and the permitting path through Contra Costa County that catches out-of-town crews flat-footed. This is not flatland roofing. Steep lots, complex planes, and fire-code requirements make Kensington a specialty market, and we treat it that way.
Why Ridgeline Roofing Co. of California Is Kensington’s Preferred Roof Replacement & Installation Company
Our reputation in Kensington was built one roof at a time, mostly through neighbors telling neighbors on streets like Somerset Avenue and Dartmouth Road. We don’t chase storms; we chase the job done right. Homeowners here tend to stay put for decades, and they remember who showed up, who documented the work with photos, and who came back when something needed tweaking.
Response time matters on a hillside. Water finds the path of least resistance, and on a steep Kensington lot that path often runs straight into a bedroom ceiling. Our phones are staffed live 24 hours a day, seven days a week. Call at midnight, you get a person who can dispatch a crew, not a voicemail tree promising a callback “during business hours.”
Our technicians are background-checked, uniformed, and trained in steep-slope safety protocols including full harness rigging and debris containment. We photograph every inspection from your actual roof - not the driveway, not a drone at 200 feet - and we share those photos with you before any work begins. The same standard we’d hold for work done in our own mother’s home.
We’ve served Kensington and surrounding East Bay communities for over 42 years. We hire local crews, train apprentices into journeymen, and plan to be here in thirty years. That matters when your roof carries a 50-year material warranty and you need someone around to honor it.
Our Roof Replacement & Installation Services in Kensington
Full Roof Replacement
Most Kensington homes were built between the 1920s and 1950s, and many still carry original or second-generation roofs that have outlived their service life. A full replacement on a typical 2,000-square-foot hillside home in Kensington runs $22,000-$38,000 for asphalt shingles, $35,000-$55,000 for metal, and $40,000-$65,000 for clay or concrete tile. Complex roof planes with multiple dormers - common in the Tudor Revival and Period Revival styles along Arlington and Dartmouth - add tear-off labor and underlayment complexity. We handle the Contra Costa County permit pull, the Cal Fire VHFHSZ material certification, and the final inspection scheduling. One call, one crew, one completed job.
New Construction Roofing
New builds in Kensington are rare given the built-out hillside, but additions and detached workshops on the larger acreage properties near the Tilden Park boundary are not. We spec and install complete roofing systems for these structures, matching or exceeding the fire rating of the main residence. On a heavily wooded acre near the Tilden Park boundary, we replaced the original wood shake roof on a 1940s Tudor Revival with a Class A fire-rated metal roof. The steep 10/12 pitch and complex dormer valleys required full safety rigging and a two-day tear-off to avoid damaging the surrounding redwoods. We finished the job in a single trip, calibrating the heavy-duty opener springs ourselves to handle the detached workshop’s oversized carriage door.
Asphalt Shingles
Asphalt remains the practical choice for many Kensington homeowners, particularly those replacing aging composition roofs on Craftsman bungalows. We install GAF Timberline HDZ and CertainTeed Landmark lines with Class A fire ratings that satisfy Cal Fire requirements for the VHFHSZ. Typical installed cost: $4.50-$7.50 per square foot in Kensington, with most jobs falling in the $18,000-$32,000 range. The marine layer that pushes through the Golden Gate and swamps Kensington’s hillsides creates persistent moisture on north- and west-facing slopes, so we specify algae-resistant granules and full synthetic underlayment on every job. No substitutions.
Metal Roofing
Metal is increasingly the right choice for Kensington’s fire-conscious hillside properties. Standing seam and stone-coated steel systems carry Class A ratings, shed moss and lichen better than composition, and withstand the wind gusts that channel across the exposed ridgelines above El Cerrito. Installed cost typically runs $10-$16 per square foot, or $35,000-$55,000 for a standard Kensington home. We are authorized installers for multiple metal product lines and handle the specialized flashing details that complex dormer configurations demand.
Tile Roofing
Clay and concrete tile suit the Period Revival architecture common in Kensington and carry excellent fire ratings. Weight is the constraint: many 1920s-1950s structures require structural assessment before tile can be specified. We coordinate engineering review through Contra Costa County when needed. Typical range: $40,000-$65,000 installed. The look lasts generations if the underlayment beneath is done right. We use only premium synthetic underlayment, never felt, and we document every layer with photos.
Flat Roofing
Flat and low-slope sections appear on Kensington additions, dormers, and detached garages. We install TPO, modified bitumen, and built-up systems with proper drainage design for the heavy winter moisture these surfaces collect. Small flat sections are often included within a larger pitched-roof quote; standalone flat jobs typically run $8,000-$18,000 depending on size and access.

Common Roof Replacement & Installation Problems We See in Kensington Homes
- Fire-code compliance failures on VHFHSZ properties. Contractors accustomed to Berkeley or Albany permitting sometimes miss that Kensington is unincorporated and subject to Cal Fire’s Class A material requirements, not standard city codes. We’ve been called in to redo jobs that failed final inspection because the original crew installed non-compliant materials. The fix costs more than doing it right the first time.
- Hidden deck rot beneath moss-choked north-facing slopes. Kensington’s marine layer moisture cultivates aggressive moss and lichen growth, especially on slopes facing Tilden Park. Tear-off without proper inspection of the sheathing beneath can leave compromised decking that voids the underlayment warranty. We inspect every square foot and photograph what we find.
- Undersized structural support for heavy tile or metal systems. Pre-1960 framing was not designed for modern concrete tile or standing seam loads. We assess structure as part of every replacement quote and coordinate engineering when reinforcement is needed - before materials are ordered, not after delivery.
- Wind damage to ridge and edge details on exposed ridgeline homes. Kensington’s elevated position channels stronger gusts than the flatlands below. Improperly secured ridge caps and starter strips lift and fail. We use manufacturer-specified fastening patterns, not shortcuts, and we warranty the workmanship for 90 days with our Done Right Promise.

FAQs - Roof Replacement & Installation in Kensington
No - there is no City of Kensington. Because Kensington is unincorporated, roofing permits are pulled through Contra Costa County’s Building Inspection Division, and the VHFHSZ designation triggers additional Cal Fire material requirements. We handle the County permit application, the Class A material specification, and the inspection scheduling as part of every job. Call (877) 367-1429 and we’ll confirm exactly what your property requires.
Yes. Our crews are trained in steep-slope safety protocols, including full harness rigging and debris containment, which is essential for Kensington’s complex roof planes and hillside lots. We minimize disruption to your landscaping and neighbors. The 10/12 and steeper pitches common off Arlington Avenue and near Blake Garden are routine for us - not an afterthought.
Yes, if you hire a contractor who knows to apply it. Every full replacement we install in Kensington uses Class A fire-rated materials that satisfy Cal Fire’s Very High Fire Hazard Severity Zone requirements. We document the material rating and provide certification for your records and for the County inspector. Crews used to standard city permitting in Albany or Berkeley often miss this step.
We specify algae-resistant shingles with copper-containing granules on all susceptible slopes, and we install full synthetic underlayment that outperforms felt in persistent moisture conditions. During tear-off, we inspect the decking beneath moss-heavy areas for hidden rot - a common find that we document and discuss with you before proceeding. Ignoring it voids warranties and guarantees future leaks.
Yes. Acreage properties near Tilden Park and throughout Kensington’s wooded hills often include detached workshops with carriage doors or oversized openings that standard crews aren’t equipped to work around. We’ve replaced roofs on these structures while protecting the doors, the framing, and the surrounding trees - and we’ve handled the structural calibrations that heavy-duty hardware demands. Call (877) 367-1429 to discuss your specific building.
