Fast, Reliable Roof Repair Across Claremont
Roof repair in Claremont typically runs between $350 and $1,600 for most leak fixes, flashing work, and shingle or tile replacement, and we can usually have a crew to your home within one to two business days after the initial inspection. Claremont roofs carry a particular set of problems: decades-old clay barrel tile, heavy tree canopy, and a historic preservation process that changes how repairs get done. If water is getting in, call us at (866) 942-0875 and we’ll walk the roof, find the actual source, and give you a straight answer on scope and cost.
We’ve worked the Village streets, the College Heights tracts, and the foothill builds near the north end. We know what the Architectural Commission expects, what the oak litter does to valleys, and what an honest repair quote looks like here. That local knowledge changes the work, and it changes the price.
Why Oakmont Roof Repair Is Claremont’s Preferred Roof Repair Company
Claremont homeowners call us because we carry seven major roofing brands, not one, and because we’ll tell you when a repair makes sense and when it doesn’t. Noel Fierro runs this company the way a roofer should: inspection first, options second, pressure never. That matters in a city where a bad patch job can mean a ceiling full of water six months later and an Architectural Commission problem on top of it.
Our Roof Repair team works only on roofing. No gutters, no siding, no general contracting. Every technician who shows up in Claremont spends their entire week on roofs. When we inspect a 1920s Spanish Colonial Revival in the Village, we know what the original felt failure looks like under clay tile. When we inspect a mid-century ranch near the Colleges, we know what Santa Ana wind damage does to ridge caps. That focus shows up in the work.
We also know Claremont’s permit and review process means repairs aren’t always straightforward. Some cities rubber-stamp a standard composition shingle. Claremont doesn’t, at least not in the historic districts. We’ve handled enough jobs here to quote accurately the first time and flag commission concerns before they become change orders.
Styles & brands we work with






Metal Roof Repair in Claremont
Metal Roof Repair in Claremont most often means correcting failed fasteners, seam separation, and rust-through at old galvanized panels on mid-century and foothill homes where metal was used as an accent or a full roof plane. Claremont’s hot, dry summers expand metal panels repeatedly, and the fasteners eventually back out. We see it most on north Claremont custom builds and a cluster of 1950s split-levels where standing seam was common. A typical metal roof repair in Claremont runs $450 to $1,350 depending on seam access, panel type, and whether the substrate has started to rot.
Fastener and Seam Work
Loose fasteners let water track down the screw shanks and into the decking. We pull the failed fasteners, replace them with oversized screws and gasketed washers, and re-secure the panel laps. Where seams have separated, we clean and re-seal them with metal-compatible sealant, then inspect the underlayment below for rot.
Rust and Panel Replacement
Rust never stops once it starts. We cut out the corrosion, replace the affected panel section, and color-match as closely as the original finish allows. If matching isn’t possible, we’ll tell you before we start so you can decide between a visible repair and a broader panel replacement.
Commercial Roof Repair in Claremont
Commercial Roof Repair in Claremont covers the low-slope and flat roof stock on the commercial corridors along Foothill Boulevard, Indian Hill Boulevard, and the edges of the Village. Most of it is built-up tar and gravel or modified bitumen that’s been patched too many times over the years. A commercial roof repair in Claremont typically runs $850 to $2,800, with the wide range reflecting membrane access, deck condition, and whether we’re fixing one penetration or rebuilding a whole drain assembly.
Low-Slope Leak Sourcing
Flat roof leaks rarely show up directly under the damage. Water travels across the deck, follows seams, and drips in the wrong place. We trace the moisture path, open the membrane at the true source, and repair it properly instead of adding another layer of patch over the wrong area.
Penetration and Drain Work
HVAC curbs, plumbing vents, and clogged drains account for most flat roof failures we see in Claremont. We flash and re-seal penetrations, clear and rebuild drain screens, and check the slope for ponding. On older buildings, we’ll often find the drain plumbing itself failed, which means cutting the deck and replacing the assembly, not just the roof membrane above it.
Trusted Brands We Service in Claremont
When you need roof repair in Claremont, the brand of your existing roof matters. We stock and work with CertainTeed, Owens Corning, and IKO materials for shingle and underlayment repairs, plus Atlas for tile underlayment and flashing components. For historic clay tile salvage work, we match profiles as closely as modern manufacturing allows. We keep the most common Claremont repair parts in our local inventory, which means we’re not waiting on a shipment from Riverside to finish a valley repair on a Village home. You get real material options matched to the roof you actually have.

AfterCommon Roof Repair Problems We See in Claremont Homes
- Failed underlayment under original clay tile. The old felt from a 1920s or 1930s roof breaks down decades before the tile itself, letting water reach the decking while the roof looks fine from the street. By the time a leak shows inside, the rot at the decking and rafters is often well underway.
- Oak and sycamore litter in valleys and gutters. Claremont’s mature tree canopy is beautiful, but the leaves and acorns trap moisture along roof edges and valleys. We regularly find rotted fascia and failing underlayment at the roof edge on streets where the canopy is thick.
- Santa Ana wind damage to ridge caps and tile. Cracking and lifting along ridge lines and roof edges comes with the territory in the inland valley. Cracked tile and loose ridge caps open the roof to driven rain during winter storms, even if the rest of the tile looks solid.
- Fire-zone compliance at the foothill edge. North Claremont homes sit in a high fire-severity zone where ember-resistant detailing matters at every penetration. B vent, pipe jack, and roof edge repairs need Class A assemblies and proper ember screening, and we handle that to the current building code.
Pricing for Roof Repair in Claremont, CA

Historic clay tile relay work is the exception, usually $2,000 to $6,000 because the labor is in salvage, not materials.

FAQs About Roof Repair in Claremont
No, not if the Architectural Commission has jurisdiction over your street and the original roof material was clay tile. Claremont’s historic districts, including much of the Village and parts of the Colleges area, can compel a re-roof to reuse the original tile profile and color. That means the tile must be salvaged, stored, and relaid. We handle that process directly, and we’ll tell you at the inspection whether your specific address falls under that review. Call (866) 942-0875 and we’ll pull the address history before we quote.
We document it, we show you photos, and we give you a written change order with a price before we do any additional work. Roof repair in Claremont regularly uncovers rotted decking, failed flashing, or old termite damage once the tile comes up. Noel Fierro’s rule is simple: no surprise work without your written approval first.
Because the tile has to be removed whole, not broken off and thrown away. Claremont’s Architectural Commission requires period-correct tile reuse in the historic districts, so our crew hand-lifts each barrel tile, palletizes it, repairs the underlayment, and relays the same tile. The labor is in salvage and precision, not materials. A normal tear-off goes fast; a historic relay is slow by design and by commission mandate.
Yes. The mature oak and sycamore trees that line so many Claremont streets drop litter into valleys and gutters constantly. That litter traps moisture against the roof edge, rotting underlayment and fascia faster than a roof without tree cover. Homes on heavier-canopy streets near the Colleges and the Village typically need valley and edge repairs more often than homes on open lots.
We quote line items, not just squares, because repair pricing in Claremont depends on what’s under the tile, not just the surface area. A square of shingle repair might run $300 to $500, but if the decking below is rotted, that adds to the line item. You can compare our bid line by line, and we’ll walk you through it because we want you to understand what you’re paying for. Call (866) 942-0875 for a free estimate.
