Fast, Reliable Roof Replacement Across Claremont
Roof replacement in Claremont runs $11,000 to $28,000 for a typical asphalt shingle job, while clay tile restoration or premium architectural shingle work on a larger foothill home can reach $45,000 or more. Those numbers move because of one thing homeowners in the Village and the tree-lined College streets learn quickly: Claremont is not a tear-off-and-nail-down town. The historic districts, the Architectural Commission, and the mature oak canopy all shape what gets approved and what actually protects the home. Oakmont Roof Repair works in Claremont regularly, and we know which streets trigger review, which tile profiles have to be salvaged, and where the fire-zone rules kick in near the foothills. Call (866) 942-0875 for an honest condition assessment before you commit to anything.
Why Oakmont Roof Repair Is Claremont’s Preferred Roof Replacement Company
Claremont homeowners don’t hand roof work to someone who has to learn the city’s rules on the job. They want a crew that already knows College Avenue from Mountain Avenue, that has lifted original clay barrel tile off a 1925 Spanish Colonial Revival without cracking it, and that can tell you before the first tear-off whether the Architectural Commission will want a say. That’s the work we do. Our Roof Replacement team has handled re-roofs in the Village, in the mid-century tracts south of Foothill Boulevard, and in the custom foothill builds north of Base Line Road.
We’re not a general contractor running occasional roof jobs. Our entire service menu is roofing: inspection, repair, and replacement. That focus means the estimator who walks your roof in Claremont is the same type of specialist who will manage the tear-off, not a project manager splitting time across kitchens and additions.
We carry seven major manufacturer lines, including GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. When you sit down with us in Claremont, we’re not steering you toward one brand because it’s the only thing we stock. We match the material to the house and the Commission’s requirements, not to our inventory.
Noel Fierro leads the team, and the standard is simple: give the homeowner the facts about what’s under the tile or shingle before asking for a dollar. That is why Claremont customers keep our number saved, and why most of our work there comes from a neighbor telling another neighbor who to call. Call (866) 942-0875 to start with a straightforward inspection, not a pitch.
Styles & brands we work with






Reroofing in Claremont
Reroofing in Claremont is the most common call we get from the Village and the historic tracts, because the original tile often still looks serviceable while the felt underneath has quietly failed. The job means lifting the existing tile or shingle, replacing the underlayment and any damaged decking, and relaying the original material where the Commission requires it, or installing a new system where the home’s status allows. A full reroof on a standard Claremont ranch runs $13,000 to $22,000; homes in the historic districts with original tile salvage requirements usually land between $18,000 and $35,000 depending on how much material can be reused and how much decking has rotted out of sight.
Historic Tile Salvage and Relay
This is the work that separates Claremont from every neighboring city. On a 1925 Spanish Colonial Revival in the Village, our crew carefully lifted the original clay barrel tile, replaced the failed felt underlayment, and relaid the same tile, avoiding a full replacement that would have triggered Architectural Commission review. The homeowner kept the historic character and dodged a costly materials change. That salvage labor is real work – hand-lifting without breaking tile, stacking it safely, and relaying it to match – and it is priced into our quote from the start, not added as a surprise at the end.
Underlayment Failure Under Intact Tile
The hardest lesson for a Claremont homeowner is that tile can look perfect while the felt beneath it is crumbling. Clay tile sheds water, but it is not waterproof; the underlayment is what actually keeps the home dry. In Claremont’s hot, dry summers and Santa Ana wind cycles, that felt bakes, cracks, and eventually lets water onto the decking. We find rotted sheathing at tear-off that no one suspected from the top side. Our inspection looks for the warning signs – cracked mortar at ridges, staining at the eaves, lifted tile from the last big wind – before we ever write a replacement number.
Flat Roof Replacement in Claremont
Flat roof replacement in Claremont is a different animal from the pitched tile work in the Village, and it shows up most on the mid-century homes and additions scattered south of Foothill and across the ranch tracts. These roofs carry the same inland-valley sun that bakes the tile homes, but they fail differently: ponding water after winter rains, blistered membranes from the heat, cracked seams around vents and curbs. A flat roof replacement on a typical Claremont mid-century runs $14,000 to $26,000 depending on square footage, the condition of the decking beneath, and whether the existing membrane contains any older materials that need full removal.
Foam and Membrane Work on Mid-Century Roofs
Claremont’s mid-century homes often came with a specific system that has aged out. The foam or built-up roof is at the end of its life, and the question is whether to overlay or fully tear off. We cover both paths with our brand options, and we’re specific about when an overlay is safe versus when the decking underneath needs to be seen first. A 1960s ranch in Claremont with the original roof is going to need a full tear-off more often than not, and we’ll tell you that before you spend money on a patch that won’t hold.
Drainage and Tree Debris on Flat Roofs
Claremont’s mature sycamores and oaks are beautiful over the street, but they shed constantly, and flat roofs collect that debris in valleys and around drains. Clogged drains on a flat roof mean standing water, and standing water is what kills every membrane early. Our flat roof work includes a hard look at where water sits after a rain and how the drainage can be improved, not just a material swap. That is the difference between a roof that lasts and one that fails in five years.
Trusted Brands We Service in Claremont
We carry Atlas, Tamko, and Boral, along with GAF, CertainTeed, Owens Corning, and IKO. For Claremont specifically, Tamko and Boral come up often: Tamko for homeowners who want a strong architectural shingle without the top-tier price, and Boral for the tile-heavy historic work where the profile and color need to match what the Commission expects. We keep the material conversation simple. You tell us what the house needs and what the budget allows, and we show you which of the seven lines actually fits, rather than pushing one because it is all we have. That brand-neutral position is why Claremont homeowners who have been burned by a single-brand contractor call us for a second opinion.

AfterCommon Roof Replacement Problems We See in Claremont Homes
- Silent underlayment failure under original tile. The most expensive surprise in Claremont is rotted decking hidden beneath tile that looks fine from the curb. We see it on nearly every pre-1950 home in the Village and the historic tracts. Our inspection maps the likely rot zones before we quote, so the number on the contract reflects reality, not a guess.
- Tile cracked and lifted by Santa Ana winds. Annual wind events peel tiles off, especially on the north-facing slopes and ridge lines of foothill homes. Once a tile is gone, the underlayment gets direct sun and water, and the failure accelerates. A few missing tiles this year often becomes a full reroof two or three years later if nobody acts.
- Valleys and gutters packed with oak and sycamore litter. The mature tree canopy over Claremont is a defining feature of the town, and a constant maintenance burden on roofs. Debris traps moisture against flashing and fascia, and that moisture works its way into the decking slowly. Homes with big trees over the roof line need more frequent gutter and valley maintenance, and we check both during every inspection.
- High fire-severity zone material requirements near the foothills. The north Claremont edge sits in a fire zone, and that changes what a replacement roof has to be. Class A assemblies and ember-resistant detailing aren’t optional up there. We quote fire-zone-compliant assemblies as the default for foothill homes, not as an add-on you discover halfway through the permit process.
Pricing for Roof Replacement in Claremont, CA
Here is the straight math for the Claremont market. A basic architectural shingle replacement on a standard ranch runs $11,000 to $18,000. A reroof that includes salvaging and relaying original clay tile in the historic districts typically runs $18,000 to $35,000, because the labor is in the careful lift and relay, not the material itself. Flat roof work on mid-century homes runs $14,000 to $26,000. Large foothill custom homes with premium materials like Boral tile can pass $45,000.
| Roof Type / Scope | Claremont Price Range |
|---|---|
| Architectural shingle, standard ranch | $11,000 – $18,000 |
| Historic tile salvage and reroof (Village/tracts) | $18,000 – $35,000 |
| Flat roof replacement (mid-century) | $14,000 – $26,000 |
| Foothill custom home, premium material | $30,000 – $45,000+ |
What moves the number in Claremont is rot discovered at tear-off, the salvage rate on original tile, and whether the Architectural Commission requires specific matching material. We write allowances into the contract for decking and underlayment unknowns, and any change is priced and approved in writing before we touch that section of the roof. Call (866) 942-0875 for a written, line-item estimate. It’s free, and it won’t come with a pressure close.

FAQs About Roof Replacement in Claremont
If your home sits in the Claremont Village or one of the city’s designated historic districts, a full roof replacement that changes the material type or visible profile will generally require Architectural Commission review, and the Commission can direct you to match the original material and color. A straight reroof that salvages and relays the original tile often proceeds without a full review, because the visual condition is being maintained rather than changed. Our team checks your specific address against the city’s historic overlay before we write the quote, so you know on day one what the permit path looks like. Call (866) 942-0875 and we’ll pull up your property’s status.
Yes, and in Claremont’s historic districts this is often the smartest path. We lift the original tile without breaking what we can save, replace the failed felt underneath, and relay the same tile back onto the roof. The labor is higher than a standard shingle job, but you avoid a full materials change, skip the Commission’s matching review, and keep the home’s historic character intact. We’ll tell you the expected salvage rate – usually 70 to 85 percent on tile that hasn’t been walked on repeatedly – and write the replacement tile quantity into the quote. Call (866) 942-0875 for an inspection that tells you what’s actually reusable.
Rotted decking that’s invisible until the tile or shingle comes off. The underlayment on Claremont’s pre-1950 homes has often failed years ago, and the sheathing beneath has been soaking up moisture the whole time, so a tear-off frequently reveals sections that need replacement. That’s why we write a decking allowance into every older-home contract, and why we photograph and document every piece of rot we find so you’re not told to trust anyone’s word. If the decking is sound, the allowance goes unused and you pay nothing for it. Call (866) 942-0875 to see the tear-off and know exactly what’s underneath before you sign.
Homes along Claremont’s northern foothill edge fall within a high fire-severity zone, and that means the replacement assembly has to meet Class A fire ratings and ember-resistant detailing standards. For most of those homes, we specify a fiberglass asphalt shingle system or a tile system with the right underlayment and edge detailing, rather than a standard organic shingle or an open-eave assembly. We know which streets trigger which requirements, and the permit package we submit reflects that from the first plan, so you don’t get a rejection notice six weeks in. Call (866) 942-0875 and we’ll check your lot against the current fire-zone map.
Yes. Flat roof replacement is a regular part of our Claremont work, especially on the mid-century homes south of Foothill and in the ranch tracts built between 1950 and 1970. Those homes carry a mix of foam systems, built-up roofs, and the occasional early single-ply membrane, and most are now well past their design life. We quote the tear-off, the new membrane or system, and any drainage corrections as one job, so the flat roof won’t pond water the first winter after installation. Call (866) 942-0875 for a flat roof assessment that tells you what’s actually left of the existing system.
