Roof Replacement in Claremont - Free Roof Inspection, Written Price

Fast, Reliable Roof Replacement Across Claremont

A full roof replacement in Claremont typically runs $14,000 to $32,000 depending on the roof’s size, pitch, and what we find when the old layers come off. That price includes tear-off, decking repair or replacement, underlayment, new material, flashing, and cleanup. For homes north of Foothill Boulevard in the Very High Fire Hazard Severity Zone, expect the higher end of that range because the assembly must meet Class A fire-rating standards.

We know Claremont’s roofs differently than a company that just drives in from somewhere else. The pre-war bungalows around the Village, the mid-century ranches south of Arrow Highway, the hillside homes backing up to the Claremont Hills Wilderness Park. Each one has its own failure points, and we’ve seen most of them. If your roof is at the end of its life, call Greg Holloway and the Tilehurst Roofing team at (945) 303-9821 for a written estimate before any work starts.

Why Tilehurst Roofing Is Claremont’s Preferred Roof Replacement Company

Claremont homeowners have been burned before. They’ve had roofers no-show, change the price at the door, or finish a repair that failed within months. That’s exactly the problem Tilehurst Roofing was built to solve. We’re part of the Kingswell family of roofing companies, founded in 2000, and we operate by a simple set of rules we call The Kingswell Way: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails.

Every call to (945) 303-9821 is answered by a live person. Not a voicemail, not a callback queue. Evenings, weekends, holidays. When you schedule an estimate, you get a written line-item price in your hands before a single nail is driven, and that number doesn’t change once the crew arrives.

We also understand what Claremont’s location demands. The Santa Ana wind front that channels along the base of the San Gabriels tears up marginal hip flashing and ridge caps faster than flatland cities like Montclair or Ontario ever see. When our uniformed, background-checked technicians walk your roof, they’re looking specifically for wind-lift failures, fire-zone compliance issues, and decking rot hidden under old skip sheathing. That’s local knowledge that matters.

Asphalt Shingle Roof Replacement in Claremont

Asphalt Shingle Roof Replacement in Claremont is the most common re-roof we do, and it’s a bigger job here than homeowners expect, because the 105°F summer heat accelerates granule loss and thermal cracking ahead of manufacturer projections calibrated for milder coastal markets. The work involves tearing off the old shingles down to the decking, inspecting and typically replacing rotted or fire-damaged sections, laying fresh underlayment, installing new shingles, replacing drip edge and flashing, and sealing every penetration. Most Claremont asphalt re-roofs run $14,000 to $24,000 depending on square footage, roof pitch, and decking condition.

Architectural Shingle Upgrades

Many Claremont homeowners choose architectural shingles over standard three-tab because they hold up better to the wind gusts that come down off the San Gabriels. We stock architectural options from GAF, CertainTeed, and Owens Corning, and the upgrade typically adds $2,500 to $5,000 to a full replacement. The thicker lamination resists wind uplift and hides minor decking irregularities common on older homes.

Decking Replacement Over Skip Sheathing

The pre-war Craftsman and Spanish Colonial homes in Claremont were often built with skip sheathing: spaced boards instead of solid decking. Modern shingle warranties require solid substrate, so if you’re re-roofing one of these homes, expect decking replacement with new OSB as part of the job. That runs roughly $1.50 to $3.00 per square foot of decking replaced and can add $2,000 to $6,000 to the total project. We flag this in the estimate upfront, so the number you sign is the number you get.

New Roof Installation in Claremont

New Roof Installation in Claremont comes up most often on additions, ADUs, or full teardown re-roofs where the existing structure simply isn’t worth saving. It differs from a re-roof because we’re building the roof assembly from the framing up rather than working over what’s already there. For new construction or major remodels in Claremont, plan for $18,000 to $32,000 depending on roof size, complexity, and the material you choose. Every new roof we install in the city goes through full building-department permitting and inspection.

Flat Roofing for Additions and ADUs

Claremont’s ADU boom means more flat roofs than the city’s historic housing stock ever had. Flat roofing demands a different system entirely: modified bitumen, TPO, or PVC membrane, with tapered insulation for drainage. We install all three, and a typical flat roof on an ADU or home addition runs $12,000 to $22,000. Poor drainage on a flat roof in Claremont’s occasional heavy downpour years leads to ponding and leaks fast, so we pay extra attention to slope and drain placement.

New Construction Roofing

For new construction in Claremont, particularly in fire-hazard zones north of Foothill Boulevard, the roof assembly must be designed for Class A compliance from day one. We work with builders and homeowners during framing to spec the right decking, underlayment, and roofing material so the fire-marshal review goes through cleanly. Starting the roofing conversation at the framing stage saves thousands in rework later.

Trusted Brands We Service in Claremont

We install material from GAF, Tamko, and Atlas, among others, because a 1920s Spanish Colonial near the Colleges needs a different product than a 1970s ranch south of the 210. GAF Timberline architectural shingles are a strong choice for Claremont’s wind corridor, while Atlas StormMaster brings Class 4 impact resistance that handles the debris Santa Ana events throw around. Tamko’s Heritage line offers solid mid-range performance for homeowners who want quality without premium pricing. We stock common components locally so Claremont jobs move fast once the permit clears. You get a genuine manufacturer choice, not whatever happens to be in the truck.

Common Roof Replacement Problems We See in Claremont Homes

• Wind-lifted hip flashing and ridge caps. Santa Ana gusts channel along the San Gabriel mountain front and pry up anything not mechanically fastened with stainless hardware. We’ve seen entire ridge lines stripped off homes that had inland-spec roofing installed only a few years earlier.
• Baked-brittle clay tile. Sustained 105°F summers heat old clay tile well past what it was designed to handle. The tile becomes brittle, and the next wind event or foot traffic snaps it. Re-bedding and replacing broken tile is constant work on Claremont’s pre-war homes.
• Rotted decking over skip sheathing. Craftsman bungalows and Spanish Colonials from the 1910s through 1940s often have spaced-board skip sheathing underneath. Decades of small leaks rot those boards invisibly. A re-roof that skips decking replacement passes a visual inspection and then leaks at the drip edge within a decade.
• Fire-zone compliance surprises. Homeowners north of Foothill Boulevard frequently discover their straightforward shingle swap triggers a full permit and fire-marshal review requiring Class A assembly. Contractors who don’t flag this in the estimate lose the job or eat the cost difference. We put it in writing before you sign anything.

FAQs About Roof Replacement in Claremont

Does a roof replacement north of Foothill Boulevard in Claremont need a fire-rated assembly?

Yes. CAL FIRE designates nearly everything north of Foothill Boulevard toward the Claremont Hills Wilderness Park as a Very High Fire Hazard Severity Zone, which means any re-roof must meet Class A fire-assembly standards under current California code, regardless of what material was there before. That often means new OSB decking over old skip sheathing, fire-rated underlayment, and a full building-department permit with fire-marshal review. Call (945) 303-9821 and we’ll tell you exactly what your address triggers before you spend a dime.

My 1920s bungalow near the Claremont Colleges has original wood shake. Can it be re-roofed over?

No, and it shouldn’t be. Original wood shake is not Class A rated, and any re-roof on that home requires tear-off and a compliant assembly. We pull the shake, lay new OSB over the skip sheathing, install fire-rated underlayment, and then put down your new roofing material. The original shake has been doing an honest job since before the Depression, but it’s no longer legal in Claremont’s fire zones and it’s a liability anywhere in the city. Call (945) 303-9821 for a written estimate on the full replacement.

Why do Claremont clay tile roofs lose tiles in the wind when other cities don’t?

Flatland cities like Montclair and Ontario sit miles from the mountain front and don’t get the same channeled wind. Claremont sits at roughly 1,150 feet at the base of the San Gabriels, and Santa Ana events funnel directly down the slopes. Sustained gusts catch the exposed edges of clay tile, particularly along hips and ridges, and pry them off if they weren’t mechanically fastened with stainless hardware and properly bedded. The cheap inland-spec re-roof that reuses old fasteners loses those tiles again in the next wind event. We specify hot-dip-galvanized drip edge and stainless fasteners on every Claremont tile roof for exactly this reason.

How much does the coastal-spec versus inland-spec roof differ in cost in Claremont?

The coastal-spec version of a Claremont re-roof, meaning Class A assembly, new OSB decking, stainless fasteners, ice and water shield through valleys, and sealed penetrations, typically runs 20 to 30 percent more than the inland-spec version that reuses old decking and standard hardware. On a $20,000 job, that’s a $4,000 to $6,000 gap. But the inland-spec version in Claremont’s wind and heat corridor fails within a decade in ways the cheap price never accounts for: lifted flashing, leaks at the drip edge, cracked tile, premature shingle granule loss. You pay now or you pay twice. Call (945) 303-9821 and we’ll write both specs out for you side by side so you can see exactly what the differences are.

Do Claremont’s 105°F summers really shorten the life of asphalt shingles?

They absolutely do. Most asphalt shingle warranties are calibrated for milder climates, but Claremont’s sustained summer heat accelerates granule loss and thermal cracking well ahead of the printed lifespan. We’ve pulled shingles off Claremont roofs that were installed 12 years earlier and looked like 20-year-old material. Choosing an architectural shingle from GAF or Atlas adds laminated thickness that resists heat and wind better than three-tab, and we recommend that upgrade for any Claremont home, not just the ones in the fire zone. Call (945) 303-9821 for a free estimate on an asphalt shingle replacement built for this specific climate.
