Kensington, California
Fire-Rated Roofing Specialists | Serving Kensington Since 1996
Pacific Coast Roofing Service understands the roofing challenges facing Kensington homeowners. Your community sits in a Very High Fire Hazard Severity Zone, which means Class B fire-resistant roofing materials aren’t optional: they’re required by building code. With 58.5% of Kensington homes built before 1940, most roofs installed in the 1950s through 1980s are decades past their 20 to 25 year lifespan.
We’re your East Bay roofing contractor specializing in fire-rated roof replacement for historic homes. With 28 years of experience serving Contra Costa County, we understand the coastal marine layer climate that accelerates shingle deterioration differently than inland heat. We work year-round, including during winter’s rainy season, because proper roof replacement protects your home immediately against storm damage and wildfire risk.

Why Kensington Homeowners Choose Pacific Coast Roofing
Your home faces roofing challenges specific to Kensington’s environment. The median home was built in 1946, making most properties 78+ years old. If you purchased a home built in the 1940s or earlier, your roof has likely been replaced at least twice. Many homeowners find they’re on third-generation roofs with shingles installed in the 1980s or 1990s, now well beyond their intended lifespan.
Kensington’s designation as a Very High Fire Hazard Severity Zone creates specific roofing requirements. Class B fire-resistant roofing materials are mandatory for all roof replacements. This requirement protects your home and may qualify you for homeowners insurance discounts ranging from 5% to 15%. When paired with proper defensible space maintenance (100-foot clearance around structures), fire-rated roofing reduces your insurance risk profile significantly.
The coastal marine layer brings persistent fog and moisture year-round. Unlike inland Contra Costa communities where extreme heat degrades shingles from above, Kensington roofs face accelerated deterioration from fog-driven moisture. This humid environment promotes algae and moss growth, particularly on north-facing slopes and areas shaded by mature trees near Wildcat Canyon Regional Park and Tilden Regional Park.
Winter rains from October through March deliver peak precipitation in February. Heavy storms reveal roof vulnerabilities through leaks that damage ceilings, walls, and insulation. Many Kensington homeowners delay roof replacement until leaks appear, but by then water intrusion has compromised roof decking and requires more extensive repairs.
Historic homes in Kensington Park, Berkeley Park, and Berkeley Highlands feature architectural details like multiple roof planes, decorative trim, and complex valley configurations. These design elements require careful flashing work to prevent water intrusion at intersections. Our crew specializes in matching period-appropriate aesthetics while installing modern, code-compliant roofing systems.
We serve homeowners throughout Kensington who value quality craftsmanship and manufacturer-backed warranties. As GAF Certified Applicators, we install fire-rated roofing systems with extended warranty coverage that protects your investment for decades.
Our Roofing Services in Kensington
Roof Replacement
If your Kensington home was built before 1960, and you’re unsure when the roof was last replaced, it’s time for a professional inspection. Most homes built in the 1940s and 1950s are on their second or third roof, with shingles installed 30 to 50 years ago. We remove old roofing materials down to the deck, inspect for rot or structural damage, replace compromised decking, and install new Class B fire-rated roofing with proper underlayment and flashing. Our replacements meet Kensington Fire Protection District requirements and qualify for manufacturer warranties.
Composition Shingle Roofing
Composition shingles with Class B fire ratings are the most practical choice for Kensington homes. They meet fire code requirements, handle coastal moisture and winter rain effectively, and last 25 to 30 years with proper installation. We install GAF Timberline HDZ and CertainTeed Landmark series shingles, both rated for fire resistance and available in colors that complement historic home architecture. These architectural-style shingles improve curb appeal while protecting your property.
Tile Roof Repair
Many Kensington homes feature clay or concrete tile roofs that match the community’s Mediterranean-influenced architecture. While tile roofs last 50+ years, individual tiles crack from seismic movement or tree impact. Winter storms reveal leaks at displaced tiles. We repair tile roofs by replacing broken tiles, re-securing loose tiles, and sealing underlayment to prevent water intrusion. Our tile work matches existing roof color and style while meeting current fire code standards.

Gutter Installation
Kensington’s tree coverage and hillside terrain require properly sized gutters. Standard 5-inch gutters overflow during January and February storms when oak and redwood debris clogs downspouts. We install 6-inch gutters for multi-level homes, add gutter guards to block leaves and needles, and position downspouts to direct water away from foundations. Properties near Wildcat Creek need overflow protection during peak winter runoff periods.
Skylight Installation
Many 1940s and 1950s Kensington homes have outdated skylights with worn flashing that leaks during winter storms. We install new Velux skylights with proper flashing systems, add energy-efficient glazing to reduce summer heat, and provide venting options for improved attic airflow. Skylight replacement transforms dark interiors common in older ranch-style and California Craftsman homes while maintaining period-appropriate exterior appearance.

Roof Ventilation
Proper attic ventilation extends roof life by preventing heat and moisture buildup. Even with Kensington’s moderate coastal climate, attic temperatures exceed 130°F during summer without adequate ventilation. This trapped heat degrades fire-rated shingles from underneath, shortening their lifespan. We install ridge vents, soffit vents, and powered attic fans to create continuous airflow that protects your roof investment and reduces cooling costs.
Green Roof Installation
For environmentally conscious Kensington homeowners committed to fire safety and sustainability, green roofs provide energy savings and stormwater management. We install vegetative roof systems with proper waterproofing membranes, drainage layers, and drought-resistant native plants suited to California’s Mediterranean climate. Green roofs reduce cooling costs, filter rainwater runoff, and create defensible space when designed to meet fire code requirements.
Kensington Neighborhoods We Serve
Our roofing crews work throughout Kensington regularly. Here’s where you’ll find us:
Kensington Park & Berkeley Park (West of Arlington Avenue)
These historic subdivisions feature English-themed street names (Lenox, Coventry, Stratford, Avon) and homes built in the 1920s and 1930s. We frequently work in this area replacing roofs on three and four-bedroom single-family homes with complex architectural details. The proximity to Tilden Regional Park means heavy tree coverage, requiring attention to moss growth prevention and gutter protection. Many properties here are approaching 100 years old, making them Kensington’s highest-priority candidates for roof replacement.
Berkeley Highlands (Northeast of Arlington Avenue)
Streets named after colleges and universities (Amherst, Oberlin, Cambridge, Columbia, Kenyon) wind through this hillside neighborhood of homes built in the 1940s and 1950s. We serve homeowners with larger estates and multi-level properties requiring specialized drainage solutions for hillside terrain. These homes often feature roofs installed 60 to 70 years ago that have exceeded their useful life. The higher location provides sweeping views but exposes roofs to increased wind and weather exposure.
Arlington Avenue Corridor
Kensington’s main commercial strip runs along Arlington Avenue near Amherst Avenue, with residential properties on surrounding hillsides. This central location provides convenient access for estimates and service calls. Homes here mix architectural styles from California Craftsman to mid-century ranch designs. We handle both period-appropriate restorations and modern efficiency upgrades for properties in this visible corridor.
Colusa Circle Area
This historic shopping district sits where major streets converge, surrounded by hillside residential properties. We serve homeowners in the surrounding neighborhoods with roof replacement, gutter installation, and tile repair services. The compact community layout means our trucks are a familiar sight throughout Colusa Circle and nearby residential streets.
Why Choose Pacific Coast Roofing
Fire-Rated Roofing Expertise
We specialize in Class B fire-resistant roofing systems required in Kensington’s Very High Fire Hazard Severity Zone. Our crew understands fire code requirements, works with Kensington Fire Protection District specifications, and installs roofing materials that meet or exceed defensible space standards. We can advise homeowners on fire-rated options that also qualify for insurance premium reductions.
Understanding of Historic Homes
Homes built in the 1920s through 1950s present specific challenges. Original roof decking may need reinforcement or replacement. Chimney flashing on brick chimneys requires specialized techniques. Complex roof planes with multiple valleys demand careful waterproofing. Our crew has 28 years of experience working with Contra Costa County’s historic housing stock and understands how to preserve architectural character while meeting modern building codes.
Coastal Climate Expertise
The marine layer affects Kensington differently than inland communities. Fog brings persistent moisture that accelerates shingle deterioration through algae growth and trapped humidity. We select roofing materials with algae-resistant formulations and install proper ventilation systems that prevent moisture accumulation. Our installation techniques account for coastal conditions that differ significantly from inland California’s heat-focused degradation patterns.
We Work Year-Round, Including Rainy Season
Many roofing contractors shut down from November through March. We don’t. Winter storms reveal roof problems immediately (leaks become obvious during heavy rain), and we respond with emergency repairs and scheduled replacements. Rainy season is an ideal time to replace your roof because you get immediate protection from winter weather. We monitor forecasts closely and work between storms, using tarps to protect exposed areas overnight.
90% Referral-Based Business
Most of our customers come from neighbor referrals. Your Kensington neighbors recommend Pacific Coast Roofing because we showed up on time, completed quality work, cleaned up thoroughly, and stood behind our warranties. We’ve built our business on reputation in educated, discerning communities like Kensington where word-of-mouth matters more than advertising.
Licensed, Bonded, and Insured
License #1002352. We carry general liability insurance and workers’ compensation coverage. When our crew works on your roof, you’re protected. We also pull proper permits through Contra Costa County and schedule required inspections. For historic properties, we coordinate with local building departments to meet preservation guidelines when applicable.
Frequently Asked Questions
How much does a roof replacement cost in Kensington?
Roof replacement costs in Kensington typically range from $15,000 to $40,000 depending on roof size, pitch, material choice, and architectural complexity. A standard 1,800 square foot home with composition shingles costs $18,000 to $28,000. Historic homes with complex roof planes, multiple chimneys, or tile roofs cost more due to specialized labor and premium materials. Class B fire-rated materials add minimal cost (typically 5% to 10% over standard products) but are required by code. We provide free estimates with detailed pricing. Call (510) 912-5454 to schedule your inspection.
What are Class B fire-rated roofing materials?
Class B fire-rated roofing materials resist flame spread and provide moderate protection against fire penetration. They’re required in Kensington’s Very High Fire Hazard Severity Zone. Most modern composition shingles (including GAF Timberline HDZ and CertainTeed Landmark series) carry Class B ratings. These materials undergo standardized testing for surface flame spread, fire brand resistance, and radiant heat exposure. Class B rating means your roof provides defensible space protection during wildfire events.
Can fire-rated roofing lower my homeowners insurance?
Many insurance carriers offer premium discounts ranging from 5% to 15% for homes with fire-rated roofing in high-hazard zones. Discounts increase when combined with defensible space maintenance and other wildfire mitigation measures. Check with your insurance provider about specific discount programs. We can provide documentation of your Class B fire-rated roof installation for insurance purposes.
Do you work on roofs during Kensington's rainy season?
Yes. We replace roofs year-round, including November through March when Kensington receives most of its annual rainfall (peak precipitation in February). We monitor weather forecasts closely and work between storms. During active roof replacement, we use tarps to protect exposed areas overnight. Many homeowners prefer winter roof replacement because leaks are obvious during rain, and immediate repair prevents interior water damage and mold growth.
How do you handle moss and algae growth on Kensington roofs?
The coastal marine layer creates ideal conditions for moss and algae growth, particularly on north-facing slopes and tree-shaded areas. During roof replacement, we remove all biological growth and treat affected areas. We install algae-resistant shingles with copper or zinc granules that inhibit future growth. We also recommend proper roof ventilation and periodic professional cleaning for homes with heavy tree coverage near Wildcat Canyon or Tilden parks.
What makes historic Kensington homes different for roofing?
Homes built before 1950 often have original roof decking that requires evaluation for rot, sag, or structural compromise. Many historic homes feature complex roof planes with multiple valleys, decorative trim, and period-appropriate architectural details. We specialize in matching these design elements while meeting modern building codes. Chimney flashing on brick chimneys requires specialized techniques not needed on newer homes. Our crew understands how to work with Kensington’s historic housing stock respectfully and effectively.
How long does roof replacement take?
Most Kensington homes take 2 to 4 days for complete roof replacement. A standard 1,800 square foot home takes 2 to 3 days. Larger estates, complex architectural details, or tile roofs take longer. Historic homes with multiple roof planes and architectural elements may take up to a week. We provide timeline estimates during your free inspection based on your specific property.
Do you offer emergency leak repair?
Yes. We respond to emergency calls during Kensington’s rainy season. If your roof leaks during a storm, call (510) 912-5454. We provide temporary repairs to stop water intrusion and schedule permanent repairs once weather permits. Emergency tarping service prevents interior damage, protects ceilings and walls, and buys time until we complete proper fire-rated roof replacement.
