A clay tile roof lasts 50–100 years — often outliving the home itself — with a Class A fire rating, natural cooling, and the timeless Mediterranean beauty that defines Bay Area architecture. We install, replace, maintain, and repair authentic clay tile across San Jose and the greater Bay Area.
A clay tile roof is a roofing system built from individual fired-clay (terracotta) tiles laid over a waterproof underlayment on the roof deck. The tiles shed water, sun, and fire for 50 to 100 years and never fade, rot, or burn, while the underlayment beneath them does the actual waterproofing and is renewed once every 30 to 50 years. Choose from authentic Mission (barrel), S-curve, and flat profiles to match Spanish colonial, Mediterranean, or contemporary architecture.
The longest lifespan in roofing — clay routinely outlasts three or four asphalt roofs (and even concrete tile), so it is often the last roof a home ever needs.
Class A fire rating — non-combustible fired clay is one of the best roof coverings for California's wildfire and ember exposure.
Priced at $15–$25 per square foot installed — higher upfront than asphalt, but with a 60–70% ROI the cost per year is one of the lowest in roofing.
Built for the weight — at roughly 8–10 lbs per square foot, clay is heavy, so we confirm your framing can carry it before a single tile goes on.

In most cases, just the underlayment. Fired clay tiles last 50 to 100 years, but the felt or synthetic underlayment beneath them — the layer that actually keeps water out — wears out in 30 to 50 years. When your tiles are still sound but the roof is leaking, the fix is a lift-and-reset: we carefully remove your original clay tiles, tear off and replace the failed underlayment and flashings, then re-set the same tiles. It costs far less than a full roof replacement because you are not buying new tile.
Recurring leaks, dark staining on the underside of the deck, and slipped or brittle tiles usually point to failed underlayment rather than failed tile. If large areas of clay are cracked or the profile is discontinued, a full replacement may make more sense. A roof inspection tells you definitively — and it is free with an estimate.
Installed clay tile runs about $15–$25 per square foot with a 50-year material warranty — the tile itself is the most expensive part of the system. Reusing sound tiles over new underlayment can save five figures versus a full tear-off, exactly what we did on the Watsonville restoration below. It is one part of our broader tile roof repair & replacement work.
Whether you're building new, replacing an aging roof, or restoring a historic one, we install, maintain, and repair authentic clay tile the right way — matched to your home's architecture, framing, and budget across San Jose and the Bay Area.
The classic half-round barrel profile that defines Spanish colonial and Mediterranean homes. Fired terracotta holds its natural color for a century and is the choice for historically accurate installs and restorations.
The interlocking S-profile gives the Spanish barrel look with faster, more weather-tight coursing. A Class A, non-combustible roof ideal for the South Bay's fire-prone, sun-drenched climate.
Clean, low-profile flat clay tile suits contemporary and transitional architecture. The same century-long fired-clay durability with a crisp, modern line and unlimited natural terracotta tones.
Your clay tiles are fine — the waterproofing underneath is not. We lift and stack the tiles, replace the underlayment, flashings, and any rotted decking, then re-set your original tile. The economical alternative to a full tear-off, and part of our inspection-first repair work.
Beauty that lasts generations — and a roof you may never have to replace. In the South Bay's fire-prone, sun-drenched climate, clay is the most durable, lowest-lifetime-cost roof you can put on a home.
Clay tiles last 75 to 100+ years, far outlasting asphalt shingles and rivaling even metal roofing — delivering an outstanding return over the life of the home.
Non-combustible fired clay carries the highest Class A fire rating plus superior wind resistance — critical protection in California's wildfire-urban-interface neighborhoods.
Clay's thermal mass and the air space beneath each tile help regulate indoor temperatures, reducing cooling costs by up to 20% and adding 10–15% to home value.
Craftsmanship that honors a material built to last a century — and because clay is heavy, we start under the roof, with the structure, and document every stage through final City inspection.
Clay weighs roughly 8–10 lbs per square foot versus about 2.5 for asphalt, so we first confirm your rafters, trusses, and decking can carry it. If reinforcement is needed we scope it up front — typically $1,000 to $10,000 — with no surprises mid-project.
We remove the old roof (or lift and stack your tiles), inspect and repair the deck, and install premium waterproof underlayment with new valley and headwall flashing — the layer that protects for decades beneath the tile.
Your chosen Mission, S-curve, or flat clay tiles are set with precise coursing, flashing, and ridge detailing to Tile Roofing Industry Alliance standards for beauty and watertight performance.
A full quality review, magnetic-sweep site cleanup, City of San Jose final inspection, and warranty documentation — so your new clay roof is ready to last generations, backed by our workmanship guarantee.

A 16310 Bonney Rd home's Spanish clay tile roof was cleaned, repaired, and restored — proof that with the right care, a clay roof can look new for a century. We saved the homeowner's original tile instead of a full replacement.
Clay tile roofs last 50–75 years in the Bay Area, and with proper care many remain durable for nearly a century — three to five times longer than asphalt shingles.
Clay tile roofing runs about $15–$25 per square foot installed. The upfront cost is higher than asphalt, but with a 50–100 year lifespan and a 60–70% ROI, the cost per year is one of the lowest in roofing.
Usually just the underlayment. Fired clay tiles last 50 to 100 years, but the underlayment beneath them — the layer that actually waterproofs the roof — wears out in 30 to 50 years. If your tiles are still sound, a lift-and-reset replaces the underlayment and flashings while reusing your original clay tile, which is the most cost-effective fix.
Clay tile weighs roughly 8–10 lbs per square foot, versus about 2.5 for asphalt shingles, so we perform a structural load assessment before any install. If your framing needs reinforcement it typically costs $1,000 to $10,000, and we scope it up front so there are no surprises mid-project.
Sometimes. Clay tile is heavier than most materials and some homes need structural reinforcement. We perform a thorough structural assessment before installation and reinforce only if your home requires it.
Yes. Clay's natural thermal mass and the air space beneath the tiles help regulate indoor temperatures, reducing cooling costs by up to 20% in hot Bay Area summers.
You can, but carefully and only where necessary, since clay tiles can crack under foot traffic. For inspections or repairs it is best to have a professional who knows how to step on the tiles correctly.
Very little. Periodic inspections to catch cracked or slipped tiles and to check the underlayment keep a clay roof performing for generations, which is why we offer routine maintenance.
