Fast, Reliable Roof Repair Across Claremont
Roof repair in Claremont is a different job than it is in most Southern California cities. The mix of 1900s-1930s Craftsman bungalows near the Colleges, 1920s Spanish Colonial Revival homes in the Village, and 1950s-1970s tract housing on the south and east sides means no two roofs fail the same way. We’re Weathervane Roof Repair, and we work exclusively on roofs. Inspection first, repair when it’s warranted, replacement only when it’s genuinely needed. If you’ve noticed a water stain on a ceiling, a missing shingle after a Santa Ana wind event, or cracked flashing around a chimney, call us at (877) 755-4274. We’ll come out, get on the roof, and tell you exactly what you’re dealing with.
Why Weathervane Roof Repair Is Claremont’s Preferred Roof Repair Company
We’ve spent enough time on Claremont roofs to know what the Claremont climate does to them. The Inland Empire heat bakes asphalt shingles dry, and when the occasional winter storm rolls through, the failures that were hiding all summer finally show themselves. Homeowners here tend to be suspicious of high-pressure sales pitches, and we don’t blame them. Our approach is simple: we diagnose before we quote, and we quote before we work. We carry no allegiance to a single manufacturer. We work with shingles from CertainTeed, Owens Corning, and IKO, among others, so the recommendation matches the roof, not a vendor contract.
Our local reputation in Claremont comes from telling people the truth, even when that truth is “you don’t need a repair yet.” Sometimes a loose shingle is just a loose shingle. When a repair is needed, we show up when we say we will, do the work properly, and leave the roof better than we found it. Gil Tanner, who leads our team, has built this company on the principle that a roofing specialist should be able to explain any problem in plain English, without jargon or scare tactics.
Styles & brands we work with






Flat Roof Repair in Claremont
Flat roof repair in Claremont often comes down to one thing: the sun. Low-slope roofs here take brutal UV exposure, and older flats on Claremont’s south and east side tract homes from the 1950s through 1970s are reaching the age where seams fail and ponding becomes a real problem. A small split at a seam or a crack around a vent boot lets water sit, and by the time it shows up inside, the damage underneath has typically been underway for a while. We assess the membrane, check for soft decking, and recommend either a surgical patch or a larger section repair, depending on what the roof tells us.
What We Check on Flat Roofs
We look at flashing terminations, drain points, and any area where the roof holds water after a rain. On modified bitumen and older built-up roofs, we test the membrane for brittleness. A repair on a flat roof in Claremont typically runs $450 – $900 for a standard patch, while a vent boot replacement lands in the $250 – $400 range.
When a Flat Roof Needs More Than a Patch
If the decking beneath the membrane has gone soft, or if seams are failing in multiple locations, the honest answer is a selective tear-out and re-cover. We’ll show you why, with photos and a clear explanation, and we’ll give you the cost before any work starts.
Shingle Roof Repair in Claremont
Shingle roof repair in Claremont’s Craftsman and bungalow neighborhoods is rarely just about replacing the shingles. On the older homes near the Colleges and Village, original wood shingles are common, and they hide soft decking until you start pulling. Also, the intense summer heat on south- and west-facing slopes dries out asphalt shingles prematurely, causing granule loss and cracking that repeats every few years if the section isn’t properly addressed. When we handle shingle replacement, we match the existing profile and color where possible, and we inspect the decking beneath before nailing anything down.
Shingle Replacement Done Right
We pull the damaged shingles, inspect the decking, and only then decide whether a patch is enough or whether a larger section needs to come off. A typical shingle replacement in Claremont runs $350 – $650, depending on the size of the area and the slope. Valley repair, which Claremont’s older homes need frequently, runs $500 – $900.
Flashing and Vent Boot Failures
Flashing repair is the unglamorous work that saves roofs. On Claremont’s 1920s Spanish Colonial Revival homes, original flashing was often galvanized steel, now decades past its useful life. We replace it with modern materials sized and bent to match the existing profile, so the repair doesn’t stick out and doesn’t trigger preservation commission rejection.
Trusted Brands We Service in Claremont
We work with shingles from seven major manufacturers, including CertainTeed, Owens Corning, and IKO, but not because a vendor told us to. The reason is simpler: Claremont has too many roof types for anyone to do competent repair work with a single brand’s product line. A 1920s bungalow with wood shingles needs a different approach than a 1960s tract home with three-tab asphalt. When you call us for a repair, we can match what’s already on your roof, and if matching isn’t possible or sensible, we’ll present a recommendation that fits the house’s architecture, the neighborhood’s expectations, and your budget.

AfterCommon Roof Repair Problems We See in Claremont Homes
- UV degradation on south- and west-facing slopes: The Inland Empire sun is relentless, and asphalt shingles on these exposures dry out and crack years before the rest of the roof. We see this most often on homes in the 91711 zip code’s 1950s-1970s tract sections. A roof with repeated cracked shingle repairs on the same slope usually needs a full replacement on that plane.
- Hidden decking rot under original wood shingles: On the 1900s-1930s Craftsman and bungalow homes near the Colleges and Village, original wood shingles can look intact from the ground while the decking beneath has been rotting for years. Repair jobs on these homes frequently turn into decking replacement once we open the section up.
- Valley and chimney flashing failures: Claremont gets long dry spells, and the first winter rain is when most valley and chimney flashing problems surface. If you see staining on a ceiling near a chimney or in a room below a valley, the leak has usually been there longer than you think.
- Preservation commission material mismatches: If a previous contractor used modern flashing or mismatched tile on a historic Claremont roof, the Claremont Historic Preservation Commission may flag it during a review. Our repair process accounts for like-for-like matching before we file anything.

FAQs About Roof Repair in Claremont
Expect a materials-matching process before any installation work begins. If your home sits in one of Claremont’s historic districts near the Colleges or Village, the Claremont Historic Preservation Commission can require like-for-like replacement of clay tile or wood shingles. We start by inventorying what’s on the roof, searching for salvaged tile from other Claremont roofs when needed, and only then filing the permit. Repairing a historic roof in Claremont is a sourcing and compliance job as much as a roofing job, and we handle it that way from the start. Give us a call at (877) 755-4274 to discuss your specific roof.
We stop the work, document what we found with photos, and put a written price in front of you before we do anything else. We responded to a call on a 1920s Craftsman bungalow near the Colleges where a winter storm had exposed failed flashing around a chimney. Opening up the section revealed outdated wiring in the attic and undersized framing that required a code upgrade before new underlayment and ice and water shield could go in. The homeowner got a written quote for the added scope, approved it, and we finished with salvaged clay tile matched from another Claremont home. No surprises, no change orders presented after the fact. For an exact quote on your repair, call (877) 755-4274.
Yes, we repair flat roofs throughout Claremont, including the low-slope and built-up roofs common on 1950s-1970s tract homes on the south and east sides of the city. We handle membrane splits, seam failures, ponding areas, cracked vent boots, and parapet flashing. Most flat roof patches in Claremont run $450 – $900. If a flat roof is beyond repair, we’ll tell you that plainly and give you numbers for a full replacement. Call (877) 755-4274 to schedule a free estimate.
Look for granule buildup in gutters, curling or cracked shingles, water stains on ceilings, and daylight visible through attic boards. In Claremont specifically, south- and west-facing slopes degrade faster from UV exposure, so check those first. Staining around chimneys or beneath valleys after the first winter rain is a strong indicator of failed flashing. If you see any of these, call (877) 755-4274 and we’ll inspect the roof, tell you what we found, and give you a quote before any work starts.
Yes, inspections are free, and they’re a standalone service, not a sales funnel. Gil Tanner built Weathervane on the idea that a roof inspection should tell you the truth about your roof, even when that truth is “you don’t need any work right now.” If a repair is warranted, we’ll show you why with photos and give you a written line-item quote. If it isn’t, we’ll say so. Call (877) 755-4274 to schedule a free inspection.
