What to expect
What a cedar shake roofing visit covers
Cedar shake roofing involves installing hand-split wood shakes—typically western red cedar—which offer beauty and durability compared to asphalt shingles (three-tab or architectural styles), synthetic materials (TPO, EPDM, PVC membranes), or alternatives like slate, concrete tile, or clay tile.
Installation begins with a thorough roof inspection.
We secure the roof deck substrate (plywood or OSB sheathing) and install synthetic underlayment with ice-and-water shield along eaves and valleys.
Each shake is hand-set, secured with ring-shank nails, and sealed with roof cement and mastic, staggered to prevent buckling and water intrusion.
In San Jose, cedar shake roofing suits Spanish Colonial Revival homes, mid-century ranches, and contemporary designs across the roofline.
Winter rain storms stress the roof system, so we ensure proper ventilation (ridge vents, soffit vents, and attic fans) to prevent ice dams and condensation.
Algae-stained shakes are cosmetic—a natural effect of low humidity and seasonal moisture—and don't indicate failure.
We waterproof and weatherproof critical areas including valleys, chimneys, and dormers using counter-flashing and boot flashing techniques.
Cost typically ranges $8,000–$15,000 for 1,500–2,000 square feet, depending on roof pitch, substrate condition, and whether we recover an existing roof or perform a complete tear-off.
Equipment includes roofing shovels, pry bars, and torches for working with bituminous mastic. Most projects take 3–5 days.
Cedar shake typically lasts 40–60 years with periodic maintenance: replacing split shakes, resealing flashing, and clearing moss.

What drives the price
Cedar is priced by grade, treatment and the ventilation the roof needs to dry properly.
Before you book
Fees for cedar shake roofing in San Jose are set by the provider you choose, not by this site.
Ask for the number and the deliverable in writing before anyone starts.
- Shake grade
- Grade and thickness drive both the material cost and the roof life. Ask for the grade in writing.
- Underlayment system
- Cedar needs a drainage plane and ventilation detail that asphalt roofs do not. That detail is where cost and longevity live.
- Fastening and spacing
- Hand-nailing and correct spacing take longer than gun-nailing and affect how the roof weathers.
- Maintenance expectations
- Cedar needs periodic care. Ask what the provider recommends and what that costs over time.

Questions
Cedar Shake Roofing in San Jose
How long does cedar shake roofing last in San Jose?
Cedar shake roofing typically lasts 40–60 years in San Jose's climate.
Our dry summers with intense sun and winter rain storms stress the material, but regular maintenance—replacing split shakes and resealing flashing—extends the roof's life significantly.
Most homeowners find cedar shake a sound long-term investment when properly maintained.
Do algae-stained shakes mean my roof is failing?
No. Algae staining is purely cosmetic, not structural damage. San Jose's low humidity and seasonal moisture actually encourage natural greying and algae growth on untreated cedar.
Stained shakes are still sound and performing their waterproofing function.
If you prefer the appearance of newer shakes, we can apply preventive treatments or replace heavily stained areas without redoing the entire roof system.
What's included in a professional cedar shake roof inspection?
Our roof inspection covers the condition of each shake, integrity of flashing and counter-flashing at chimneys and dormers, ice-and-water shield placement, ventilation systems (ridge vents and soffit vents), and the substrate (plywood or OSB decking).
We check for rot in the sheathing, water intrusion signs, proper nail fastening, and assess the roof's overall weatherproofing. You receive a detailed estimate with photos.
Can I repair individual shakes instead of replacing the whole roof?
Yes, if only a few shakes are split or missing. We can remove damaged shakes and install matched cedar replacements, which is cost-effective for isolated damage.
However, if multiple areas show rot in the substrate or widespread buckling across the roof deck, a complete tear-off and re-roof may be more economical and longer-lasting.
Does cedar shake roofing meet San Jose building code requirements?
Yes, when installed by a Trusted roofer.
San Jose building code requires proper roof inspections, approved synthetic underlayment, correct fastening with ring-shank nails, and flashing details at valleys and step flashing at chimneys.
Our crew ensures every installation passes final inspection and meets all local code standards for waterproofing and weatherproofing.
How long does a cedar roof last?
It depends on grade, ventilation and maintenance. Ask for the specific product and thickness, and for examples of roofs the provider has installed locally.
Can cedar be repaired or only replaced?
Individual shakes can be replaced when the rest of the roof is sound. Widespread rot or a failed underlayment usually means replacement.
Does cedar need special maintenance?
Yes — debris removal, checking for rot and attention to flashings. Ask what the provider recommends and what it costs per visit.
