AfterFast, Reliable Roof Replacement Across Pomona
Roof replacement in Pomona runs $11,500 to $24,000 for a standard asphalt shingle roof on a 1,200 to 2,000 square foot home, with architectural shingles landing between $14,500 and $22,000 depending on decking condition and fire-rating requirements. That’s the honest range before anyone shows up with a ladder, and we’ll put it in writing before any work starts. Greg Holloway leads our Pomona crews, and we answer the phone live 24 hours a day at (945) 303-9821.
Pomona is not West Covina, and it’s not Claremont. This stretch of the San Gabriel Valley sits in a wind corridor that funnels Santa Ana events straight down from the Cajon Pass, and the housing stock here runs older and tighter than most of LA County. That changes how we bid, how we stage materials, and what the permit office will actually approve. If you’re already researching roof replacement, you want someone who has worked a tight Pomona lot before.
Why Tilehurst Roofing Is Pomona’s Preferred Roof Replacement Company
We’re part of the Kingswell family of roofing companies, founded in 2000, and our Pomona customers consistently tell us the same thing: the written price they got upfront matched the final invoice. Every job starts with a Written Price Before Any Work Starts, which means no change orders at the door and no discovering the decking is rotted after the crew has already stripped the old shingles. When we inspect a roof in Pomona, we check the decking before we quote, because decades of 103°F inland summers have done real work to the wood under those shingles.
Our crews know the difference between the flat roofs near downtown and the steep pitches up toward Phillips Ranch. We’ve worked the Wilton historic corridor, the neighborhoods around Lincoln Park, and homes up against the foothills where LA County fire hazard maps change the material spec mid-permit. Every technician on a Pomona job is background-checked and uniformed, and a live person answers our phones around the clock. No voicemail. No “we’ll call you Monday.”
One thing that matters more in Pomona than almost anywhere else in the valley: we hand-notice shared wall neighbors before tear-off. When a 1920s bungalow sits three feet from the house next door, the neighbor deserves to know the dumpster is coming and the demo will be loud. That’s not a policy in a handbook. It’s how you keep a tight lot civil.
New Roof Installation in Pomona
New Roof Installation in Pomona means a full tear-off down to the decking, replacement of any rotted or soft sheathing, new underlayment, drip edge, flashing, and a complete shingle or tile system built to the wind and fire requirements of your specific parcel. We see this most often on homes where the existing roof has granule loss you can see from the curb, patched leaks that keep coming back, or decking that’s starting to sag between the rafters. For a standard asphalt shingle new roof on a Pomona home, expect $11,500 to $19,000 for three-tab or basic architectural, and $16,000 to $24,000 for premium architectural with a Class A fire-rated assembly where the VHFHSZ maps require it.
Class A Fire-Rated Assemblies
If your Pomona address sits in the Very High Fire Hazard Severity Zone, the county requires a Class A fire-rated roof assembly on any re-roof. That’s not optional, and it’s not a suggestion from the inspector. It changes both the material spec and the number on the quote, and it’s a conversation seasoned local roofers initiate before the contract is signed. We’ll pull the fire hazard map for your parcel during the estimate, not after the permit is filed.
Steep Pitch and Wind Uplift Engineering
Homes up against the San Gabriel foothills often have steeper pitches and take the full force of the Cajon Pass winds. We fasten to a 130 mph wind uplift spec on those exposures, upgrading nailing patterns beyond what a coastal LA roof would ever need. The extra fasteners are cheap insurance compared to watching your ridge cap end up in the neighbor’s yard after a Santa Ana event.
Reroofing in Pomona
Reroofing in Pomona is different from a new roof installation in one key way: the existing roof’s structure and decking tell us what we can keep and what has to go. On most Pomona homes built between 1920 and 1960, that means stripping old shingles off single-layer plank decking that has baked through decades of inland heat cycling. When the sheathing shows dry rot or the fasteners pull loose from the soft wood, we replace it. On a 1920s Spanish Colonial Revival on the Wilton historic corridor, we stripped the original low-slope tile and found exactly that: dry rot and fastener pull-through that would have failed the next roof too. We replaced the sheathing first, then laid new underlayment, ice and water shield in the valleys, drip edge, and a Class A architectural shingle assembly with starter strip and ridge vent. The homeowner saw the sheathing replacement line item before we bought a single square of shingles.
Decking Replacement
The difference between a quote that holds and one that grows by $4,000 at the door is whether the roofer inspected the decking before writing the number. In Pomona, with this housing stock, we assume the decking is suspect until we see it. Many of these homes have original plank decking from the Coolidge administration. We inspect from the attic and from the roof surface, and we tell you what we found in plain language: this is soft, this is rot, this is coming out.
Reroofing Without Full Tear-Off
If your decking is solid and the existing roof is a single layer, a reroof can involve laying new shingles over the old in limited cases. But Pomona’s age profile makes full tear-offs the far more common call. We don’t sell overlays on homes where the decking hasn’t been inspected in fifty years. That’s how you buy a roof that fails from underneath.
Trusted Brands We Service in Pomona
You have a genuine choice in materials here, and we stock parts for Pomona jobs from GAF, CertainTeed, Owens Corning, and IKO, plus options from Atlas, Tamko, and Boral. That matters because a Craftsman bungalow on a tight lot off Garey Avenue suits a different shingle profile than a ranch house up in Phillips Ranch. We don’t work from a single house brand, and we won’t tell you the product that works is “whatever’s on the truck.” If a Pomona parcel requires a Class A assembly, we spec the product that meets the rating and matches the home.
Common Roof Replacement Problems We See in Pomona Homes
- Wind uplift from the Cajon Pass corridor. Santa Ana events funnel through the Pomona Valley with real force, peeling improperly fastened shingles and hip caps off roofs that would hold fine in coastal LA. We fasten to a 130 mph spec on exposed exposures.
- Permit-stage fire-rating surprises. A northern Pomona parcel mapped into the VHFHSZ requires a Class A assembly, and jobs sold on standard 30-year architectural shingles stall at inspection. We pull the fire hazard map before the quote, so the spec is right before signing.
- Dry rot and fastener pull-through on plank decking. Homes along the Lincoln Park and Wilton corridors carry 1920s-1950s plank decking baked through decades of 103°F plus summers. Skipping full deck inspection leads to callbacks once the new roof is loaded on soft wood.
- Granule loss and shingle blistering from inland heat. Pomona runs 15 to 20 degrees hotter than coastal LA in summer, with no marine layer to cool the shingles. UV degradation here cuts manufacturer-rated shingle life by a third or more, which is why we see premature failure on roofs less than 15 years old.
Pricing for Roof Replacement in Pomona, CA
Here are real numbers for the Pomona market, not placeholder ranges. A basic three-tab asphalt shingle roof on a 1,200 square foot home runs $11,500 to $14,500. Architectural shingles on a 1,500 to 2,000 square foot home run $14,500 to $22,000. A Class A fire-rated architectural assembly, required in northern Pomona’s VHFHSZ parcels, adds $1,800 to $3,500 depending on the product. Decking replacement, when the old plank wood fails, runs $3 to $5 per square foot of sheathing replaced.

FAQs About Roof Replacement in Pomona
Only if your parcel sits in LA County’s Very High Fire Hazard Severity Zone. That designation applies to portions of northern Pomona near the San Gabriel foothills, and it requires a Class A fire-rated assembly on any re-roof. We check the fire hazard map for your address during the estimate, before anything is signed, so there’s no mid-permit surprise. If you’re not sure, call (945) 303-9821 and we’ll look it up while you’re on the phone.
We stage materials in the driveway where possible, and park the dumpster on the street with a posted permit when the lot can’t hold it. On a tight lot, access affects the quote: a roof that requires carrying materials up a side yard or over a neighboring structure costs more in labor than a roof with direct driveway access. We walk the site before we write the number, so the price reflects the actual access, not an assumption.
We hand-notice shared wall neighbors before any tear-off starts. That means knocking on the door, explaining the schedule, and letting them know when the demo noise will happen and when the dumpster arrives. In Pomona’s older neighborhoods, where homes sit close, that courtesy is the difference between a civil job and a dispute. It’s standard practice on every Tilehurst job.
If your home was built between 1920 and 1960 and still has original single-layer plank decking, there’s a strong chance some portion of it needs replacement. Decades of 103°F to 107°F summers have dried out the wood, and the old fasteners lose their grip. We inspect from the attic and the roof surface before we quote, and if sheathing needs to come out, it’s in the written price before work starts. You’ll never hear “we found rot” after the old roof is already gone.
Two reasons, working together. Pomona sits in a Santa Ana wind corridor funneling straight down from the Cajon Pass, which puts wind uplift stress on shingles and ridge caps that coastal LA roofs never experience. And Pomona’s inland valley position means summer temperatures regularly exceed 103°F with no marine layer relief, which accelerates UV granule loss and shingle blistering. A roof rated for 30 years in West Covina can be toast in 18 to 22 years here. That’s why the fastening spec and the material choice matter more in Pomona than almost anywhere in the San Gabriel Valley. Call (945) 303-9821 for a free estimate that accounts for both.
