Roof replacement in Claremont typically runs $9,500 – $18,500 for a standard single-story home with architectural asphalt shingles, with tear-off, permit, and new underlayment included.

We serve all of the 91711 ZIP code, from the tree-shaded bungalows near the Claremont Colleges down to the mid-century tracts south of Foothill Boulevard. Kurt Hensley and our crew know Claremont’s housing stock and the specific ways its roofs fail. Call (866) 942-4187 for a free estimate. We’ll give you line-item pricing, not a hand-waving number.
Why Orange County Roofing Co Is Claremont’s Preferred Roof Replacement Company
We’re not a Claremont storefront, and we won’t pretend to be. What we are is a roofing contractor that does a steady stream of work here, and the reason is simple: we understand the tree canopy. Sycamores and oaks define this town, and they define the failure pattern of most roofs here too. Leaves pack into valleys. Acorns clog downspouts. The first hard winter rain backs water up under shingle courses, and by spring you have a ceiling stain nobody connects to October.
Claremont homeowners call us because our Roof Replacement team doesn’t just tear off and nail down. We inspect valleys before we quote, and we price the ice and water shield and re-decking that a canopy-heavy neighborhood actually needs. You get a written scope from our team, including permit fees and dump fees, so nothing surprises you mid-project. Kurt Hensley has built our reputation on telling homeowners what the roof genuinely needs, not what’s easiest to sell.
Styles & brands we work with






Asphalt Shingle Roof Replacement in Claremont
Asphalt Shingle Roof Replacement is the most common full replacement we perform in Claremont, particularly on the south-side ranch and tract homes built between 1955 and 1985 whose original three-tab shingles are now 20-plus years old. The work involves a full tear-off to the deck, replacement of damaged or rotted decking boards, new synthetic or felt underlayment, code-required flashing, and installation of your chosen shingle with the correct nailing pattern. A typical asphalt shingle roof replacement in Claremont runs $9,500 – $14,500 for a single-story home, depending on roof size, pitch, and how much decking needs replacing.
Architectural Shingles and Wind-Rating Compliance
Most Claremont homes look right with architectural shingles. They carry a thicker profile than three-tab and more manufacturers rate them for higher wind speeds when nailed correctly. We install to the six-nail pattern on architectural lines like GAF Timberline HDZ, Owens Corning Duration, and Atlas Pinnacle, because the manufacturer’s wind warranty only applies when the fastening schedule is followed. A four-nail roof may hold fine for years, but when a Santa Ana wind event peels it, the manufacturer denies the claim and you’re on the hook.
Decking Replacement Under Claremont’s Older Homes
A 1940s bungalow near the Claremont Colleges almost never has perfectly sound decking. Between original wood shake, decades of heat in the attic, and valley areas that soaked up overflow, you’ll usually find sections of dry rot at the eaves and valleys. We price re-decking per sheet ahead of the job so you know the worst case before we start. Cheap bids often exclude decking replacement entirely, then hit you with a change order once the roof is open.
New Roof Installation in Claremont
New Roof Installation in Claremont is for full tear-off and reconstruction, not a re-roof over existing shingles. We see this need on the 1920s and 1930s homes around the Village and the college-adjacent streets, where original wood shake or low-slope materials have finally reached the end of their service life. Since these homes often have old framing spacing and original sheathing, a proper new installation means working down to the rafters in spots. A new roof installation on a 1,200 – 1,800 sq ft Claremont home typically lands between $11,000 and $18,500, including permit, underlayment, decking, and architectural shingles.
Historic-Look Roofing for College-Area Homes
Owning a 1920s bungalow on Indian Hill Boulevard or a craftsman near Memorial Park doesn’t mean you have to give up the historic profile. Architectural shingles from GAF and CertainTeed now mimic cedar shake and slate textures closely enough that most owners don’t notice the difference from the curb. We work with you on the color and profile that matches the original material while giving you a manufactured product with a real warranty, rather than raw wood shake.
Flat and Low-Slope Roofing
Claremont has a fair share of low-slope roofs on mid-century moderns and additions. These need a different system: modified bitumen or single-ply membrane, not asphalt shingles. Our crew handles both, and we’ll tell you honestly when a low-slope section needs a membrane rather than patching or shingling. If your home mixes slopes, the quote should show two line items, not one blended price.
Trusted Brands We Service in Claremont
We install products from seven major manufacturers, including Owens Corning, IKO, Atlas, and Tamko, so you can choose the roof that fits your home and budget rather than the one we’re incentivized to sell. Because we stock from multiple lines, our material recommendations come from what the Claremont home actually needs: a high wind-rating shingle for a house exposed to Santa Ana gusts, or a thicker profile for a pitched bungalow where curb appeal matters. We keep a range of samples for you to compare in person during the estimate, and we’ll show you the warranty tier for each option so you can weigh coverage honestly.

AfterCommon Roof Replacement Problems We See in Claremont Homes
- Valley clogging from sycamore and oak debris. Leaves and acorns pack into valleys from October through December, and the first intense rain sits against flashing until it forces water under the shingles. By the time you see a stain inside, the flashing has usually been leaking for weeks.
- Four-nail shingle installation on 1970s and 1980s tract homes. South-side Claremont homes built during that era were often roofed with a four-nail pattern. Shingles hold until a strong wind event, then peel in sheets. No manufacturer wind warranty covers four-nail failures.
- Cracked 15-pound felt underlayment under original shake. The hot, dry Claremont summers bake old felt until it’s brittle. When we tear off shake near the colleges, the felt often crumbles in our hands. A cheap tear-off that reuses the old felt voids the underlayment detail that both code and warranty expect.
- Rotted fascia and soffit from clogged gutters. Gutter debris in canopy-heavy neighborhoods sends overflow down the fascia board, rotting it behind the gutter line. We see this on nearly every older Claremont home where gutters haven’t been cleaned twice a year.

FAQs About Roof Replacement in Claremont
Claremont follows the California Building Code, which requires roof coverings to meet wind-resistance standards for the region’s exposure category. Most architectural shingles meet the baseline requirement, but the manufacturer’s wind warranty only applies when the shingle is nailed per the brand’s fastening schedule, typically a six-nail pattern for higher wind zones. Your permit documentation should reference the specific shingle and fastening pattern used. Call (866) 942-4187 if you want us to review what your existing roof was installed with.
Look at five line items: underlayment type, whether ice and water shield is included at valleys and eaves, decking replacement allowance, nailing pattern, and whether permit and dump fees are listed. A Claremont bid that omits valley ice and water shield on a tree-shaded lot is not a real bid; it’s a teaser number that will grow once the roof is open. We give you a fixed line-item quote before you sign, so you’re comparing equal scopes.
Yes. When a wind event damages a Claremont roof, insurers typically ask for proof that the roof was installed to current code and the manufacturer’s wind-rating standard before paying a claim. Documented nail patterns, ice and water shield at valleys, and the permit record all support your claim. We provide that documentation as part of the job, and in at least one Claremont case, the homeowner’s insurer accepted our wind-rating documentation when the policy was rewritten after a storm claim.
A canopy-aware quote includes valley ice and water shield, full-width flashing at all valley transitions, and an explicit decking replacement allowance, because Claremont’s mature oaks and sycamores mean your roof’s valleys do more water work than the average Southern California roof. It should also include gutter and downspout assessment, since clogged drainage is the primary reason roofs leak here, not shingle failure. We quote all of that on our first visit.
Yes, and that’s a request we get regularly from homeowners on streets like College Avenue and Yale Avenue. We use architectural shingles with a shake or slate profile from GAF, CertainTeed, or Atlas that read as traditional from the street but carry manufactured-product warranties. The roof structure underneath gets full modern treatment: new underlayment, ice and water shield, and re-decking where the wood has dried out.
