Authentic Wood and Composite Shake Solutions in San Jose
Engineered specifically for residential and commercial building requirements in San Jose and Santa Clara County.
Class A Pressure-Treated Fire-Retardant Cedar Shakes
California building codes strictly prohibit raw untreated wood shakes due to wildfire risks. We install Certi-Guard pressure-impregnated Western Red Cedar shakes that achieve permanent Class A and Class B fire ratings. The fire retardant is vacuum-infused into the wood grain at the mill, providing permanent ember resistance that cannot wash off in winter rains.
DaVinci Synthetic Composite Shake Conversions
For homeowners in high wildfire risk foothill zones who love the appearance of hand-split cedar shakes without the ongoing maintenance, we install DaVinci composite shakes. Molded from genuine hand-split cedar profiles, these virgin polymer shakes carry Class A fire ratings, Class 4 impact resistance, and 50-year warranties without rotting or curling.
Historic Architectural Cedar Preservation and Repair
For historic Craftsman bungalows, Tudor revivals, and ranch estates in the Rose Garden and Willow Glen, maintaining authentic wood shingle architecture is critical to preserving home value. We perform gentle preservative treatments, selective shake replacements, and specialized copper valley flashings.
Silicon Valley Environmental Factors Affecting Wood Shingles
Silicon Valley microclimates place unique thermal, wind, and seismic stresses on roofing assemblies.
Wildland-Urban Interface (WUI) Fire Regulations
The Climate Stressor: Santa Clara County building codes enforce stringent fire-hardening mandates in Almaden Valley and Silver Creek foothill zones prohibiting combustible roofing.
Our Engineering Solution: We install factory-certified Class A fire-retardant cedar assemblies incorporating fire-barrier underlayments and non-combustible gypsum deck boards.
Intense Ultraviolet Degradation and Splitting
The Climate Stressor: Hot, dry summers cause untreated natural wood shakes to dry out, curl at edges, and split along natural grain lines, allowing water into rafters.
Our Engineering Solution: We utilize 100 percent edge-grain #1 Grade Western Red Cedar shakes, which exhibit minimal swelling and shrinking compared to cheaper flat-grain shakes.
Winter Atmospheric River Moisture and Fungal Decay
The Climate Stressor: Extended winter rainfall followed by mild weather fosters wood-decaying fungi and moss growth in shaded shingle butt joints.
Our Engineering Solution: We install inter-layment breather mesh beneath shakes to promote continuous 360-degree air circulation that dries shakes quickly after rainfall.

Certi-Guard Mill-Infused Fire Retardant Technology
Never rely on topical spray-on fire chemicals, which wash away after two rainstorms. We exclusively source Cedar Shake and Shingle Bureau Certi-Guard pressure-impregnated timber, where fire-retardant polymers are forced into cellular wood fibers under hydraulic pressure.
Cedar Breather Matrix Underlayment Systems
Installing wood shakes over solid plywood can trap condensation on the underside of the wood. We install nylon matrix cedar breather mesh between the underlayment and shakes, creating a continuous drying cavity that extends shake lifespan by 15 years.
Natural Thermal Insulation Performance
Western Red Cedar possesses natural cellular air pockets that provide an R-value over twice that of asphalt shingles, providing natural thermal insulation that keeps homes naturally cooler during hot summer days.
Our 5-Stage Wood Shake Installation Procedure
Every project follows strict NRCA technical standards, manufacturer specifications, and City of San Jose building codes.
-
1
Substrate and Skip Sheathing Evaluation
We inspect existing wood framing, installing solid 1/2-inch CDX plywood decking over older skip sheathing to meet modern seismic standards.
-
2
Class A Fire Barrier Underlayment Application
We install specialized non-combustible fiberglass fire-barrier sheets and self-adhering leak barriers in all valleys and eaves.
-
3
Cedar Breather Ventilation Layer Placement
We roll out continuous three-dimensional nylon ventilation matrix to allow air circulation beneath the wood shake courses.
-
4
Precision Shake Staggering and Fastening
We install #1 Grade edge-grain shakes using stainless steel ring-shank nails, maintaining 3/8-inch expansion keyways between shakes.
-
5
Copper Flashing and Ridge Capping
We fabricate custom copper or pre-painted metal flashings and install matching factory fire-treated hip and ridge cap shakes.
Stainless Steel Fastener Corrosion Resistance
Natural cedar contains natural tannic acids that corrode standard galvanized nails, causing ugly black streaks and loose shakes. We fasten all cedar shakes with Type 304 or 316 stainless steel ring-shank nails.
Precise Side-Lap and Keyway Spacing
Wood expands when wet. Our craftsmen leave exact 3/8-inch keyways between adjacent shakes and stagger joints at least 1.5 inches across successive courses to prevent rain from reaching underlayment.
Hand-Split vs Taper-Sawn Shake Selection
We guide homeowners between rugged hand-split shakes with rustic textured faces and smooth taper-sawn shakes offering refined shadow lines tailored to specific architectural styles.

Can I convert an old wood shake roof to architectural shingles?

Why do wood shakes require stainless steel nails?
Natural cedar contains tannic acids that chemically react with and corrode standard galvanized nails. Stainless steel nails resist tannic acid and prevent black rust streaks and loose shakes.
Does homeowner insurance cover wood shake roofs in California?
Many California insurance carriers require certified Class A fire-rated assemblies or non-combustible synthetic conversions to maintain property coverage in designated foothill fire hazard zones.
