Fast, Reliable Roof Replacement Across Pomona
Roof replacement in Pomona isn’t one-size-fits-all. Between the triple-digit valley summers, Santa Ana wind corridors, and a housing stock that runs from 1920s Spanish-revival stucco to 1970s ranch tracts, a Pomona roof faces conditions that a coastal LA roof never does. Oakmont Roof Repair has been working these streets long enough to know the difference. When you call us about a roof that’s failing, we show up understanding what the San Gabriel Valley sun actually does to underlayment, flashing, and fasteners over decades. Call (866) 942-0875 and we’ll give you an honest read on what your roof needs.
Why Oakmont Roof Repair Is Pomona’s Preferred Roof Replacement Company
Pomona homeowners call us because we speak the local roof language. We know that a house off Garey Avenue with original clay tile needs a different eye than a 1960s ranch in the 91767 ZIP where the composition shingles have been baked to brittleness. Our Roof Replacement team has torn off enough Pomona roofs to know what hides underneath: disintegrated felt under intact tile, corroded flashing at stucco edges, decking gone soft at penetrations. That’s not general knowledge. That’s Pomona-specific, earned one roof at a time.
Noel Fierro leads our crews, and he’s built the company around a simple rule: tell the homeowner what’s actually wrong, then give them real options. We carry seven major roofing brands, so the recommendation isn’t dictated by what we happen to stock. It’s dictated by what your house needs.
Styles & brands we work with






Flat Roof Replacement in Pomona
Flat roof replacement in Pomona comes with its own set of demands. The eastern San Gabriel Valley heat sits on a flat roof differently than a pitched one, baking the membrane from above while the low humidity pulls moisture out of the materials. We replace flat roofs throughout Pomona’s 91766 and 91767 ZIPs, where mid-century ranch additions often carried flat sections over patios, carports, and room extensions. A full flat roof replacement in Pomona typically runs $8,500 to $16,000 depending on square footage, decking condition, and membrane system chosen.
Membrane Selection
We walk Pomona homeowners through the real choices: modified bitumen, TPO, and PVC systems each behave differently under sustained UV and thermal cycling. The heat here isn’t theoretical. A membrane that works fine in coastal LA can fail years early in Pomona if it’s not spec’d for the valley’s summer intensity.
Tapered Insulation and Drainage
Flat roofs in Pomona don’t just need waterproofing. They need proper slope so the rare winter rain actually drains instead of ponding. Our flat roof replacements address drainage at the source, not as an afterthought.
Roof Installation in Pomona
Roof installation in Pomona means building from the deck up for a house that’s going to face decades of valley sun, Santa Ana winds, and the occasional winter downpour. We handle full new construction roof installation across Pomona, from the newer builds near the 91797 corridor to additions on older homes throughout the city. A complete roof installation in Pomona typically runs $11,000 to $22,000 for a standard single-family home, with material choice driving the range.
Decking and Underlayment First
Before a single shingle or tile goes down, we inspect and often replace roof decking that’s been compromised by years of heat and hidden leaks. Pomona’s dry climate hides decking damage. You can’t see it from the curb, but the wood may be soft at every penetration from decades of slow, undetected moisture intrusion during the rare rains.
Fastener and Flashing Specs
We spec stainless and hot-dip galvanized fasteners throughout, because cheap galvanized nails give out early under Pomona’s heat cycling. Valley flashing, pipe boots, and drip edge all get upgraded corrosion resistance. The cheap spec fails fast here. We don’t install it.
Trusted Brands We Service in Pomona
Oakmont carries GAF, CertainTeed, and Owens Corning product lines, which means we can match your roof to your actual budget and your home’s architectural style. A Spanish-revival near the Pomona College side calls for a different material than a mid-century ranch in the 91766 tract. Because we stock multiple brands rather than pushing a single manufacturer’s line, the conversation stays honest. For Pomona customers, that also means faster turnaround on material orders and a recommendation based on what your roof needs, not what we’re trying to move.

AfterCommon Roof Replacement Problems We See in Pomona Homes
- Disintegrated underlayment under intact clay tile and wood shake. The valley sun bakes the felt out decades before the tile or shake gives up. The roof looks fine from the street. It isn’t.
- Heat-cycled, curled wood shake on older bungalows. Pomona’s dry inland air and the Santa Ana corridor dry out shake faster than roofs a few miles west in the cooler LA basin.
- Baked-out asphalt shingles on 91766/91767 ranch tracts. Triple-digit summers and intense UV degrade composition shingles faster here than in coastal communities.
- Corroded fasteners and failed flashing on stucco-on-wood-frame homes. Pomona’s 1920s through 1970s housing stock has brittle stucco edges and original galvanized nails that give out early.

FAQs About Roof Replacement in Pomona
The tiles themselves rarely fail first in Pomona. The underlayment underneath, the felt membrane that actually keeps water out, gets baked by valley sun and thermal cycling until it disintegrates. So water gets through the failed membrane while the tile above still looks intact. We find this constantly: lift a tile, see dust. Call (866) 942-0875 and we’ll confirm what’s actually happening before you spend anything.
We replace them. Curled, heat-cycled shake on Pomona’s older bungalows generally can’t be patched back to reliability. We do full wood shake replacement, and we also walk homeowners through the case for switching to architectural asphalt shingles or tile where the budget and the house style make sense.
A re-roof in Pomona is usually a membrane job wearing a tile hat: we remove the tile or shake, replace the failed underlayment, and reset the original surface material. A full tear-off strips everything to the deck, replaces damaged decking, and installs all-new material. The right call depends on what we find when we lift those first tiles.
Line-item detail is everything. Ask what underlayment is specified, what fasteners they’re using, and whether decking repair is included. Two quotes can be hundreds of dollars apart on paper and thousands apart in reality once you look at what’s being installed under the surface. That’s where Pomona roofs actually fail.
They should. We recommend shingles and roof systems rated for higher wind uplift when we work homes in wind-exposed parts of Pomona, particularly the northern and eastern edges where the Santa Ana corridor hits hardest. The roof may look calm on most days, but the wind event is what finds the weak fasteners and failed seals.
