Fast, Reliable Roof Repair Across Pomona
Roof repair in Pomona runs $350 – $1,200 for most shingle and flashing fixes, and $650 – $2,400 when decking, underlayment, or structural work is involved. We work throughout 91766, 91767, 91768, and 91769, and we know what these older Pomona homes throw at a crew. If you’ve got a leak, lifted shingles, or damage from a Santa Ana wind event, call (866) 321-6172. We’ll get on the roof, figure out what’s actually going on, and give you a straight answer on what it costs to fix.
Opening Up an Older Pomona Home: What We Actually Find
Most of Pomona’s housing stock was built before 1950, and a lot of it predates World War II. That matters because roofs on these homes weren’t framed or decked the way modern code requires. In the 91766 and 91767 ZIP codes, repair crews routinely pull off failed composition shingles to find original 1×4 skip sheathing with little or no underlayment beneath it. What looked like a simple patch from the ground becomes a re-nail and decking question before a single new shingle goes down. We’ve run into this more times than we can count in the flats off Garey Avenue and the streets north of Holt.
That’s why our process in Pomona starts with inspection, not a quote. We get on the roof, lift the damaged section, and check what’s underneath before we put a number on paper. If the decking is soft or the skip sheathing has pulled loose, you know before we start, not after. Any surprise gets priced and approved in writing. No change orders dropped on you mid-job. Rick Dominguez set this company up so the crew never tears into a roof without a plan for what might be hiding under it.
Styles & brands we work with
Why Van Nuys Roofing Co Is Pomona’s Preferred Roof Repair Company
We’ve repaired roofs on Pomona bungalows, Craftsman-style homes, and post-war tract houses from Phillips Ranch to Lincoln Park. Homeowners here call us because we don’t push a brand. We’re material-neutral. We work with GAF, CertainTeed service in Pomona, Owens Corning, IKO, Atlas, Tamko, and Boral, so when we recommend a shingle or a repair approach, it’s because it fits your roof and your budget, not because a supplier put a number on our board this quarter.
What Pomona homeowners tell us they value most is this: we inspect first and recommend second. You get an honest condition assessment without being on the hook for a repair. If the roof has years left, we’ll tell you. If it needs a patch, we’ll show you photos. If it’s done, we’ll say that too and show you the math on repair versus replacement. Our Roof Repair team handles everything from missing shingles to full valley rebuilds, and we bring the same multi-brand knowledge to every job in Pomona and the surrounding cities.
We stock common parts for Pomona’s older roof systems: architectural shingles, ridge caps, drip edge, valley metal, vent boots, and flashing in standard profiles. That means faster turnaround when your roof needs attention now. Call (866) 321-6172 and we’ll tell you when we can be out.
Storm Damage Roof Repair in Pomona
Storm Damage Roof Repair is a routine call for us in Pomona, especially after a Santa Ana wind event pushes through the 91767 flats and the neighborhoods along Towne Avenue and Garey Avenue. West-facing slopes take the worst of it. Wind gets under the shingle course, lifts the tabs, and once the seal breaks, the next gust starts peeling. Ridge caps go first, then shingles near the eaves. We typically arrive within 1 – 2 business days for wind damage, and we photograph everything before we touch it so you have documentation for any insurance claim you file.
Wind-Lift Shingle Replacement
This is the most common Santa Ana damage we see in Pomona. Shingles that are sealed properly don’t lift. Shingles that are old, brittle, or were installed over skip sheathing without a proper starter strip do. We replace lifted courses, check the seal strip on the surrounding field, and re-nail anything that’s loose. A typical wind-lift repair on a Pomona home runs $350 – $800 depending on how many courses are affected.
Ridge Cap and Valley Rebuilds
When the ridge cap goes, water follows. We rebuild ridges with new cap shingles bedded in sealant, and we flash valleys with new metal if the old stuff is rusted or torn. Valley work usually lands between $500 and $1,200 on Pomona homes, and it’s worth doing right the first time because a failed valley leaks into the interior, not just the attic.
Metal Roof Repair in Pomona
Metal Roof Repair in Pomona usually means fixing standing seam panels, corrugated metal, or older metal tile systems on homes that were re-roofed sometime in the last few decades. Metal is less common on the pre-1950 stock, but we see it on more recent additions and on some post-war tract homes in 91768 and 91769. The failures are consistent: loose fasteners, failed sealant at laps, and rust where the panel was scratched during installation.
Fastener and Sealant Repair
Metal roofs expand and contract with Pomona’s hot inland summers. That thermal cycling works fasteners loose over time, and once a screw backs out, water finds the hole. We replace fasteners with correctly sized ones fitted with EPDM washers, and we re-seal laps and transitions. On most Pomona metal roofs, a fastener and sealant repair runs $400 – $900.
Panel and Flashing Patches
When a panel is dented, rusted through, or torn, patching beats replacing the whole section. We cut out the damaged area, install a new panel piece with proper lap direction, and seal everything. Flashing at chimneys, vents, and walls is where metal roofs fail most often in Pomona, and we replace it rather than caulking over it. Panel patches and flashing replacement typically run $600 – $1,400 depending on access and the amount of metal needing work.
Trusted Brands We Service in Pomona
We service roofs built with Boral, GAF, CertainTeed, and Owens Corning materials, and because our crews know the installation specs for each, repairs don’t get undercut by guesswork. If your Pomona roof has CertainTeed shingles that need a patch matched, we know which product line to pull from and where to source it locally. If it’s standing seam with a Boral tile section, we know the attachment requirements. That cross-brand fluency means your repair looks right, wears right, and keeps whatever manufacturer warranty eligibility is still in place. We keep common Pomona profiles in local stock: architectural shingles, ridge caps, and flashing in the colors we see most often on the older homes across 91766 and 91767.

AfterThe Local Failure Modes: What a Generic Roofer Gets Wrong in Pomona
Three things keep showing up on Pomona roofs, and each one is a place where a drive-by quote goes wrong.
- Re-shingling over original skip sheathing without re-nailing or adding underlayment. The new course looks fine for a season, then a Santa Ana wind peels it back and the decking underneath keeps rotting. We re-nail the 1x4s first, add underlayment, and only then set the new shingles.
- Chasing a leak as a surface patch when the real failure is flashing. Rusted or under-driven flashing at penetrations and valleys lets water track back into the walls, and no amount of tar or caulk stops it. We find the actual entry point and replace the flashing.
- Quoting off visible damage with no allowance for what’s underneath. A roofer quotes $500 for a patch, tears off the shingles, finds open framing or failed waterproofing, and suddenly the price doubles with no written explanation. We write allowances into the contract and get any open-roof surprise priced and approved before we proceed. You see photos. You see the number. You approve it first.
Common Roof Repair Problems We See in Pomona Homes
- Dry-rot at the eaves and rakes on pre-1950 wood-frame homes. Pomona’s dry climate slows fungal growth, but older gutterless eaves and minimal overhangs let water sit on fascia and deck edges. We cut out the rot, treat what’s left, and rebuild before re-roofing.
- Lifted shingles after Santa Ana wind events, especially on west-facing slopes in 91767. The wind funnels through the flats and peels the seal. We replace lifted courses and check the entire slope for damage, because wind-lift usually isn’t isolated to one spot.
- Failed vent boots and pipe flashing on the low-slope sections common on Pomona’s tract homes. The rubber boot cracks in the heat, and water follows the pipe into the attic. A $450 vent boot replacement beats a $2,000 ceiling repair.
- Valley leaks on older composition shingle roofs with original skip sheathing. The valley is where the roof’s geometry concentrates water, and if the sheathing underneath has gaps, the water finds its way in. We rebuild valleys with proper underlayment and metal flashing, not just a patch over the top.

FAQs About Roof Repair in Pomona
Most Pomona homes built before 1950 have original 1×4 skip sheathing with little or no underlayment, and when we lift the shingles, we often find loose boards or soft decking that needs re-nailing or replacement before new roofing can go down. The repair itself might be small, but the substrate work is non-negotiable if you want it to last. We inspect first, write allowances into the contract, and get any surprise priced and approved in writing before we proceed. Call (866) 321-6172 for an exact quote.
West-facing slopes in the 91767 flats typically lose ridge caps and lifted shingles along the eaves, and we often find missing shingle tabs scattered across the field. The repair involves replacing lifted courses, rebuilding the ridge, and checking the entire slope for fractures. If the sheathing underneath is skip-laid 1×4, we re-nail it before anything new goes down. Call (866) 321-6172 and we’ll get on the roof and show you photos of what the wind actually did.
Minor repairs like shingle patches, flashing replacement, and vent boot swaps do not trigger permits or code reviews in Pomona. If we’re replacing more than about a third of the roof, or if the decking needs structural work, the City of Pomona requires a permit, and we pull it. Code upgrades depend on what we find under the shingles, and if we find open framing or substandard decking, we’ll show you what the code requires and price it before we start. Estimates are free at (866) 321-6172.
Look for three things: whether the quote includes an inspection of what’s under the shingles, whether there’s a written allowance for hidden decking or flashing work, and whether the roofer can work with the specific material on your roof. A $400 quote with no underlayment check becomes a $1,600 surprise later. Our quotes include a decking rate per sheet and a written scope for any unknowns, so you’re comparing real numbers. Call (866) 321-6172 for a line-item quote you can actually hold against another bid.
Yes, we repair metal roofs throughout Pomona, including standing seam, corrugated, and metal tile systems on homes in 91768 and 91769. Most failures are loose fasteners, failed sealant at laps, or rusted flashing at penetrations, and we replace rather than patch over those. We work with Boral, GAF, CertainTeed, and Owens Corning metal products, so we know the attachment and fastening specs for each. Call (866) 321-6172 to schedule a metal roof inspection.
