Fast, Reliable Roof Repair Across Pomona
A roof leak in Pomona rarely starts where the water shows up on your ceiling. The water travels: along a rafter, around a vent boot, under a cracked tile near the ridge, then down into the living room. Most Pomona homeowners call us after the first real winter rain, when the dry months finally hand over a soaked spot or a curl of peeling paint. We’ve repaired enough roofs in Pomona to know the older bungalows, the mid-century ranches off Garey Avenue, the quiet blocks in Westmont and Phillips Ranch. Noel Fierro built Oakmont as a roofing-only shop, and when you call (866) 942-0875, you’ll get an honest assessment, not a pitch. We work from the roof down, give you a written scope, and tell you what actually needs doing.
Why Oakmont Roof Repair Is Pomona’s Preferred Roof Repair Company
Pomona homes are not one roof type. The same block can hold a 1920s Spanish-revival with original clay tile, a 1950s ranch with aging composition shingle, and a stucco bungalow with a shake patch somebody added in the 1970s. A roofer who only does asphalt can’t properly assess the tile and shake work. Our Roof Repair team carries and works with GAF, Owens Corning, Atlas, Boral, and three other major brand lines, so the recommendation is driven by your roof, not by what’s on our truck. That matters in Pomona, where a tile roof near the historic core and a composition roof in the 91766 tract need different hands.
Our Pomona customers routinely mention the same things: the inspection came before any sales talk, the quote was itemized and held firm, and the crew treated a tight shared-wall lot like it was occupied by the owner’s own family next door. Because it often is. Pomona’s lots are narrow, driveways are shallow, and the neighbor’s bedroom window is ten feet from the work. We notice that before we quote, not after we show up.
Styles & brands we work with






Metal Roof Repair in Pomona
Metal Roof Repair in Pomona usually means one of three things: a standing-seam or metal panel roof with a failed screw gasket or seam tape, a metal valley or flashing that’s separating at the transition, or a rust-through spot where valley heat and historic-style steel have met for decades. Most of Pomona’s metal roofs are on mid-century or retrofitted homes, and the failure is rarely the panel itself. It’s the connection: the fastener, the seam, the boot, the edge. A typical metal roof repair in Pomona runs $350 – $800 for a seam or boot repair, and $700 – $1,500 when we’re pulling and replacing a rusted valley or repairing panel damage.
Seam and fastener repair
On Pomona metal roofs the rubber gaskets on roofing screws flatten and crack after years of triple-digit valley heat. Once the gasket goes, water wicks down the fastener into the deck sheathing. We replace the bad screws, reseal the overlapping seams with the right butyl or seam tape, and inspect the adjacent panels for loose or backed-out fasteners.
Flashing, valley, and edge work
Metal valleys that turn to rust usually fail at the lap joints or where the valley meets a stucco parapet. On tighter Pomona lots, access to a valley often requires careful staging against a shared wall or over a narrow side yard. We plan that access before we quote, so the repair price you see includes the real cost of safely reaching the section.
Commercial Roof Repair in Pomona
Commercial Roof Repair in Pomona covers small professional buildings, flat-roof storefronts, and low-slope warehouse roofs throughout the 91766, 91767, and 91768 corridors. The work is different from residential repair: built-up and modified-bitumen roofs need torch or cold-applied patch work, TPO roofs need heat-welding, and older commercial roofs in Pomona often carry a layer of floaters and caulked patches from previous repairs that actually made drainage worse. A flat-roof patch in Pomona typically runs $500 – $1,200 for a small penetration or seam repair, while larger membrane repairs run $1,800 – $4,500 depending on the square footage and the condition of the existing membrane.
Flat and low-slope membrane patch
We mark the leak source, cut back the waterlogged insulation or membrane, and rebuild the patch in layers. Pomona’s Santa Ana winds regularly lift poorly adhered edges and dump leaves and grit into scuppers, so we check drainage as part of every flat-roof repair. A patched leak with a blocked drain is a future leak with a bigger bill.
Tenant and access coordination
On commercial jobs in Pomona, the roofer’s day starts with parking, locked gates, overhead lines, and business hours. We coordinate work around tenant access so a dental office doesn’t get tar fumes through a rooftop HVAC intake at noon. The quote reflects that coordination, and we keep it tight.
Trusted Brands We Service in Pomona
Oakmont carries seven major roofing manufacturer brand lines, and our Pomona service area sees work across Atlas, Boral, GAF, and the others in our stock. We service Boral tile on Spanish-revival roofs, Atlas and GAF shingle lines on ranches, and metal and tile systems we’ve installed and worked on across the region. Because we order for Pomona-specific work, we can often have the materials staged at a local supply yard within days, not weeks. You get the brand match for your home and your budget, and the same crew handles the warranty-serving and installation detail.

AfterCommon Roof Repair Problems We See in Pomona Homes
- Failed underlayment under sound-looking tile or shake. On Pomona’s 1920s – 1940s tile and shake bungalows, the visible roof can look fine while the felt beneath has turned to powder after decades of valley heat. We lift a cracked tile and find bare membrane instead of felt. The repair is underlayment and flashing, not a whole new visible roof.
- Santa Ana wind damage to valleys, drip edge, and ridge vent. Wind events out of the east drive uplift under old shake and composition shingles, tearing at the ridge and loosening drip edge along brittle stucco edges. The damage is often concentrated on the east and northeast roof planes.
- Brittle stucco and drywall edges cracking around flashing. Pomona’s stucco-on-wood-frame construction means every pipe boot, wall flashing, and roof-to-wall transition is set into a material that cracks when poked. A repair near a wall or penetration often grows once the cracked stucco edge is opened, and we account for that in the quote.
- Older composition shingle baked past service life. Triple-digit summer days and UV intensity shorten shingle life across Pomona. By the time granules form visible runs in the gutters and the edges curl, the shingles are usually done. Often the smart repair is a section replacement before the leak spreads across the deck.
Pricing for Roof Repair in Pomona, CA
Roof repair in Pomona carries a floor around $300 – $500 for small work like a vent boot replacement or a few missing shingles, and a ceiling that rises when the real story is underlayment, flashing, and access. Leak repair on a Pomona composition roof typically lands in the $450 – $1,200 range. Tile underlayment work will usually run $900 – $2,500 once the visible tile is lifted and reset. Flat-roof patches range from $500 to $2,000 depending on membrane condition. Access on Pomona’s tight lots is part of the real cost, not an add-on: staging against a shared wall, protecting a narrow driveway, and working a tower in a shallow side yard all appear in the figure.

FAQs About Roof Repair in Pomona
Yes. Most Pomona tile roof repairs involve lifting the existing tile, replacing the failed underlayment or flashing beneath it, and then resetting the same tile. Tile itself routinely outlasts the membrane under it in Pomona’s heat. On a 1930s Spanish-revival bungalow off the Pomona College side near downtown, we lifted cracked clay tiles over a valley and found the original felt had turned to dust beneath them. We replaced the underlayment and rebuilt the flashing instead of selling a whole re-roof. The homeowner kept their original tile and got a dry roof. Call (866) 942-0875 and we’ll tell you whether your tile is worth saving before any work is quoted.
It changes the staging, the parking, and the protection scope. On a narrow lot with a shared wall and no side-yard access, we may need to stage materials in the front driveway or coordinate a small dump trailer, and we protect the shared wall and the neighbor’s property with plywood and tarps. Because the lot was tight and shared a wall with the neighbor on one downtown job, we staged materials in the driveway, posted notice the day before, and kept the tear-off noise inside Pomona’s daytime work window. Those access costs are included in the estimate, not discovered on day one.
Pomona generally restricts construction and demolition noise to daytime work hours on weekdays, with tighter or prohibited hours on weekends. We follow the standard weekday window of roughly 7 a.m. to 6 or 7 p.m. and avoid early morning starts on shared-wall lots. Hand tearing and quieter prep work gets scheduled inside those hours, and noisy tear-off is clustered mid-morning. If your street or district has overlay restrictions, we check before we quote so the schedule we give you is the schedule we keep.
Most repair work that stays within the existing roof system, patch-for-patch or like-for-like, does not require a permit. Structural changes, increasing the roof’s weight class, or altering the roof plane usually do. Pomona’s older bungalows sometimes sit in historic or overlay districts, and those streets can carry their own review process for visible changes. We look at the scope, the district, and the age of the home during the estimate. If a permit is needed, we flag it in the quote, handle the filing, and schedule the inspection. Nothing gets started without that cleared.
Line by line, and not by bottom line. The key is making sure the quotes describe the same repair. One roofer may quote a patch for $600 and another may quote underlayment replacement for $1,800 because the second roofer actually lifted the tile and found the felt gone. Ask each contractor what they’ll do to the underlayment, the flashing, and the perimeter edges, and whether access and protection are included. The lowest Pomona quote is often the one that skips the membrane work under the tile. Call (866) 942-0875 for a line-item estimate you can hold against any other.
