AfterFast, Reliable Roof Replacement Across Los Gatos
Roof replacement in Los Gatos runs $18,000-$45,000 for a typical 2,000-3,000 square foot home, with hillside properties on steep lots often reaching $55,000 or more when Class A fire-rated materials and structural decking repairs are required. We’re Tilehurst Roofing, part of the Kingswell family of companies, and we work Los Gatos hills and flats every week. If you call (945) 303-9821, a live person answers and we’ll schedule a real walkthrough of your roof, not a drive-by estimate.
What makes a Los Gatos roof different is what’s under it and above it: steep pitches, oak and bay canopy, CAL FIRE hazard zones, and two separate permitting authorities depending on whether your parcel falls under Town of Los Gatos jurisdiction or unincorporated Santa Clara County. We know which is which before we write your quote, because getting that wrong changes plan review, the inspector who signs off, and your timeline. This page is built around how a roof replacement actually gets done on a tight Los Gatos lot, and what it costs in real dollars.
Key Takeaways
- Full roof replacement in Los Gatos typically runs $18,000-$45,000, with hillside Class A assemblies at the upper end.
- Wood shake roofs on hillside parcels are the biggest trigger: most are grandfathered until insurance or a sale forces a Class A re-roof.
- Your permitting authority depends on your parcel, not your ZIP code. We verify Town versus County before any work starts.
- Every Tilehurst job includes a written price before work begins and a written guarantee before the crew leaves.
Why Tilehurst Roofing Is Los Gatos’s Preferred Roof Replacement Company
Los Gatos homeowners have been through a lot. No-shows, prices that changed at the door, repairs that failed within a month. That’s why Tilehurst Roofing operates under the Kingswell Guarantee, and it’s why we put everything in writing before a single nail is driven. A written price. A written guarantee on every repair. A full year of documented accountability through the 365-Day Done Right Promise. If it’s not done right, we come back and make it right. Not as a favor. As a term of the job.
Our crews work Los Gatos neighborhoods like Kennedy Road, the Almond Grove district, Belgatos, and the hillside pockets above Los Gatos Boulevard. That matters because a roofer who doesn’t know the difference between a town-permitted parcel and a county-permitted one will burn your schedule on plan review. We won’t. Our technicians are background-checked and uniformed, so you know exactly who’s on your roof, and our scheduling respects Los Gatos work-hour ordinances. Greg Holloway leads our crews, and he’s the kind of person who answers the phone and walks the roof himself before quoting a number.
We’ve built our Los Gatos reputation one steep hillside tear-off at a time, and the reviews from local customers consistently mention the same things: we showed up when we said we would, the price didn’t move, and the site was cleaner when we left than when we arrived. That’s the standard. It’s not complicated.
Roof Replacement Contractor in Los Gatos
A roof replacement contractor in Los Gatos does not just swap shingles. On the flats, the work is straightforward: strip, inspect decking, replace damaged sheathing, install underlayment and a new roof system. In the hills, it is a different trade entirely. We’re tearing off 40-year-old wood shake on a 9:12 pitch, repairing decking around dormers, re-flashing skylights and turrets, and rebuilding the roof as a Class A fire-rated assembly that meets current CAL FIRE requirements.
When does a Los Gatos homeowner need a full replacement rather than another repair? When the roof is past 20 years, when the decking is failing, or when the shake is non-compliant and the insurance carrier has already sent the non-renewal letter. We see all three on a single street in the hills, often on the same block.
Class A Fire-Rated Rebuilds
Most hillside re-roofs in Los Gatos are not optional upgrades. They’re triggered. A grandfathered wood shake roof stays legal until a storm, a sale inspection, or an insurance non-renewal forces the issue. Then the replacement must meet today’s Class A standard. We specify the full assembly: fire-rated underlayment, Class A shingles from GAF or CertainTeed, proper valley metal, and a nailing pattern the manufacturer will actually stand behind.
Steep Pitch and Complex Planes
Los Gatos hillside houses are rarely simple rectangles. Dormers, turrets, skylights, multiple roof planes, pitches above 8:12. Each one adds flashing details and material waste. A bid that treats your roof like a simple shingle swap is a bid that will change once the decking comes off. We account for the real geometry before we write the price, not after.
Asphalt Shingle Roof Replacement in Los Gatos
Asphalt shingle roof replacement in Los Gatos is the most common job we do, and the most misunderstood. A 2,000 square foot home in the flats with a straightforward gable roof will run $18,000-$28,000 for architectural shingles from CertainTeed, GAF, or Owens Corning. That same square footage on a steep hillside lot with complex planes, oak canopy debris, and required Class A underlayment will run $30,000-$45,000. The difference is access, waste, and the fire-rated assembly.
Los Gatos homeowners often ask about architectural versus three-tab. In this market, three-tab is obsolete for any home that matters to you. Architectural shingles carry a 30-year to lifetime manufacturer warranty, hold up better under the debris load from oak and bay trees, and are what lenders and insurers expect to see on a Los Gatos roof.
Decking Repair Before the Shingles
On 1970s and 1980s hillside homes, the decking under the old shake or tile is often shot. Water intrusion at the valleys, rot around penetrations, and decades of trapped moisture under heavy tile. We inspect every sheet as it’s exposed and replace what’s unsound. A re-roof that skips this step is a new roof nailed to a failing structure. That’s a repair we get called to fix.
Ice and Water Shield in the Valleys
Los Gatos gets 25-30 inches of rain a year, nearly double what San Jose sees, because Pacific storms hit the Santa Cruz Mountain foothills and dump their moisture here. We specify ice and water shield in every valley and at every eave on hillside homes. It’s the layer that keeps wind-driven rain from migrating under the shingles. It’s not optional in this climate.
Trusted Brands We Service in Los Gatos
Tilehurst Roofing installs materials from seven manufacturers, so the product fits your Los Gatos home rather than whatever happens to be in our truck. For most Los Gatos re-roofs, we commonly recommend GAF, CertainTeed, and Owens Corning architectural shingles because they offer the Class A fire ratings this market requires and the high-wind warranties that matter on exposed hillside lots. We also work regularly with Atlas, IKO, Tamko, and Boral for concrete tile and specialty applications. We stock local distribution for the Los Gatos area, which means faster material turnaround when your decking reveals more damage than expected and the job expands mid-stream.
Common Roof Replacement Problems We See in Los Gatos Homes
- Shake roofs surviving on grandfathering until a trigger hits. A 1980s wood shake roof may have been perfectly legal when installed, but now it’s non-compliant under CAL FIRE codes. The non-renewal letter or the buyer’s inspection is usually what forces the replacement, and by then the homeowner is on a deadline.
- The town versus county permitting trap. Nearly all hillside parcels in Los Gatos are in Very High Fire Hazard Severity Zones, but which government reviews your roof depends on your parcel. Town of Los Gatos and unincorporated Santa Clara County have different inspectors, different plan review paths, and different timelines. We verify before we quote.
- Steep, multi-plane roofs that get underbid. A pitch above 8:12 with dormers, turrets, and skylights means more flashing, more waste, and more labor. When a bid doesn’t account for that geometry, the price changes once the roof is open. We account for it up front.
- Oak and bay debris accelerating moss and granule loss. Hillside homes under dense tree canopy collect debris that holds moisture against the roof. Moss and lichen degrade tile mortar and asphalt granules faster than valley-floor roofs. An annual inspection and moss treatment is a legitimate recurring need in this market, not an upsell.

Here are real ranges for Los Gatos, based on the work we quote every week. A standard asphalt shingle re-roof on a 2,000-2,500 square foot flat-lot home: $18,000-$28,000.

FAQs About Roof Replacement in Los Gatos
Yes. If your Los Gatos hillside parcel is in a CAL FIRE Very High Fire Hazard Severity Zone, a re-roof trigger requires a Class A fire-rated assembly regardless of what was permitted when the shake went on. Storm damage, a sale inspection, or an insurance non-renewal each force the conversation. Once the trigger fires, you cannot legally re-roof with wood shake. The good news: Class A architectural shingles from GAF or CertainTeed meet the code and typically cut your insurance premium. Call (945) 303-9821 and we’ll verify your parcel’s hazard zone and code path before quoting.
It depends on your parcel, not your mailing address. Many Los Gatos hillside addresses fall under unincorporated Santa Clara County jurisdiction, while homes in the incorporated town go through the Town of Los Gatos Building Division. The plan review path, inspector, and timeline are different for each. We look up your parcel before we write your quote, so there are no surprises. Call (945) 303-9821 and we’ll tell you which authority applies to your property.
Yes, and it’s one of the things we do best. Tight-lot staging is standard for us in Los Gatos. We work with the Town or County on permitted street staging windows, protect the neighbor’s side yard, and run tear-off in a single chute line so the old material lands in one controlled spot. When the driveway can’t fit a full dumpster, we use staged smaller containers and haul debris out as we go. The site is swept clean every evening. Call (945) 303-9821 to discuss your access constraints – we’ll account for them in the quote.
Los Gatos gets 25-30 inches of rain a year and hillside homes sit under dense oak and bay canopy that holds moisture against the roof. We specify ice and water shield in every valley and at every eave, which prevents wind-driven rain from migrating under the shingles. We also recommend an annual inspection and moss treatment for homes under heavy canopy. The debris accelerates granule loss and degrades tile mortar faster than valley-floor roofs experience. Call (945) 303-9821 for a roof assessment that accounts for your tree cover and exposure.
Compare the line items, not the bottom number. Look for decking replacement rates per sheet, whether ice and water shield is included in valleys and eaves, which Class A underlayment is specified, and whether the flashing at dormers, skylights, and chimneys is called out separately. Then compare the guarantee: is it written, and for how long? A bid missing these items will be cheaper on paper and more expensive once the roof is open. Tilehurst gives you a written price with every line item before work starts, and a written guarantee before the crew leaves. Call (945) 303-9821 for a free estimate and we’ll walk you through the numbers line by line.
