Fast, Reliable Roof Repair Across Pomona
Roof repair in Pomona usually means one thing: wind damage. The San Gabriel Valley funnels Santa Ana gusts off the Cajon Pass straight into this city, and those dry, hot winds tear at shingles, ridge caps, and tile in ways that coastal roofers rarely see. We respond to Pomona homes across the 91766, 91768, 91769, and 91797 ZIP codes, and we know exactly what to look for when we get up on the roof. Call (866) 650-8319 for a free estimate, and we’ll give you a written scope before any work starts.
Why Gable Roof Repair Is Pomona’s Preferred Roof Repair Company
Our Roof Repair team works on Pomona roofs every week. We know that a lifted shingle field on a 1950s tract home near Ganesha Park is a different job than a missing ridge cap on a newer build off Temple Avenue. Reputation here gets earned roof by roof. Homeowners around Cal Poly Pomona, the historic neighborhoods off Holt Avenue, and the older bungalow blocks near downtown call us because we separate diagnosis from the sale. Inspection first, recommendation second. That means you get an honest read on whether your roof needs a targeted patch or a replacement, not a default push toward the bigger job. Neil Drummond built this company around the repair-first approach, and that philosophy carries into every Pomona estimate we write.

Emergency Roof Repair in Pomona
Emergency Roof Repair in Pomona almost always follows a Santa Ana wind event. Those gusts hit 50, 60, sometimes 70 mph through the valley, and we get the calls the next morning: missing ridge caps, lifted shingle courses, tile slipped out of alignment. The immediate job is to get the roof sealed enough to protect the house until a proper repair scope can be written. On the same visit, we’ll photograph the damage, mark the areas that need attention, and give you a written line-item estimate before any work is approved. Costs for emergency wind repair in Pomona typically run $400 – $900 for securing and sealing, with the full repair priced separately once we see what’s underneath.
Wind Damage Response
On an early-1960s tract home near the Cal Poly Pomona corridor, a Santa Ana event tore loose ridge caps and lifted a field of three-tab shingles, exposing original 1x sheathing that had cupped and split. We removed the damaged courses, sistered the compromised decking, laid new ice and water shield in the valleys, and reset architectural shingles with a six-nail pattern and fresh starter strip along the rake. The homeowner got a written scope showing the sheathing repair as a line item before we opened the roof, so the final invoice matched the estimate.
What Gets Damaged First
Ridge caps and rake edges take the brunt of Santa Ana winds because they sit at the roof’s highest exposure points. When those lift, the wind gets under the shingle field and starts peeling courses back. Underlayment that’s been baking in Pomona’s summer heat for 20-plus years is often brittle by the time the wind finds it.
Flat Roof Repair in Pomona
Flat Roof Repair in Pomona shows up most often on mid-century homes in the 91766 ZIP code, where low-slope designs were common in tract developments from the 1950s and 1960s. These roofs carry a different kind of stress: thermal cycling. Pomona’s hot, dry summers bake the membrane, and when winter rain finally arrives, any seam or penetration that cracked in the heat becomes a leak path. Flat roof repairs here typically run $350 – $750 for targeted patching and seam repair, while larger re-coating jobs on aging built-up or modified bitumen roofs run $1,800 – $3,500 depending on square footage.
Seam and Penetration Repair
Most flat roof leaks in Pomona start at a vent boot, drain collar, or HVAC curb. The membrane itself is often fine; the flashing around the penetration has dried out and separated. We pull the old flashing, clean and prime the area, and install new material that matches the existing system, whether that’s torch-down, modified bitumen, or a single-ply membrane.
Older Built-Up Roofs
Some Pomona flat roofs date to the original build, with layers of asphalt and gravel that have been patched repeatedly over the decades. When we open one up, we sometimes find the original underlayment has turned to powder. Repairing these requires cutting out the failed section, checking the decking beneath, and rebuilding the membrane in layers. That sheathing condition is the wild card on cost, which is why we write decking repair as an allowance in the estimate, not a surprise after the fact.
Trusted Brands We Service in Pomona
We’re brand-agnostic, which matters when your Pomona roof carries materials that some contractors won’t touch. We work with GAF, CertainTeed, and Tamko systems regularly, and our crews know the installation requirements and failure patterns for each manufacturer’s product lines. When we repair a roof, we match materials to what’s already up there, not what we happen to stock. That means your shingle color, tile profile, or membrane type comes from the right brand, not whatever’s on sale. For Pomona homeowners, that speeds up sourcing and keeps repairs visually consistent with the existing roof.

AfterCommon Roof Repair Problems We See in Pomona Homes
- Wind-lifted shingles along the rake and ridge. Santa Ana gusts get under the shingle edge and peel entire courses back. We see this most often on east-facing slopes of older tract homes where the roof takes the full force of the wind.
- Missing ridge caps exposing the underlayment. The ridge line is the first thing to go in a sustained wind event. If the underlayment underneath is original and brittle, the next winter rain finds its way into the attic.
- Slipped or cracked clay and concrete tile. Pomona’s mix of mid-century tile roofs has been through decades of thermal expansion and contraction. Tile slips out of alignment, and the underlayment beneath it, often original, is the actual waterproofing layer failing.
- Failed flashing at penetrations and valleys. Older Pomona homes, especially bungalows near downtown, have valley metal and vent flashing that’s been in place since the original build. Thermal cycling and Santa Ana dust abrasion wear the sealant down over time.

FAQs About Roof Repair in Pomona
If fewer than 30% of shingles on the affected slope are lifted or damaged, and the underlayment is intact, a repair usually makes sense. If we expose original sheathing that’s cupped, split, or water-damaged, or the underlayment has failed across a large area, a replacement is the honest call. We’ll show you photos from the roof so you can see exactly what we’re seeing. Call (866) 650-8319 and we’ll assess it for free.
Yes, if we’re removing and replacing any structural decking or altering roof framing, the City of Pomona will require a permit. When walls or roof layers are opened on a pre-1960s home, that permit can trigger requirements like upgrading underlayment to current code or adding proper edge metal. That’s why we write those potential upgrades as allowances in the estimate before we open anything up, so the final invoice is a number you’ve already seen. Call (866) 650-8319 for a written scope.
We start with an inspection that traces the leak to its actual entry point, because flat roof water travels horizontally before it shows up inside. Then we cut out the failed section, check the decking underneath, and rebuild the membrane with matching material. Most 91766 flat roof repairs run $350 – $750 for a targeted patch; larger sections or deteriorated decking move that number. Call (866) 650-8319 and we’ll price it from the roof, not from a guess.
Ask for a written line-item scope that separates materials, labor, and any allowances for hidden conditions like sheathing replacement or underlayment work. Ask whether the estimate includes disposal, flashing, and permit fees if applicable. And ask what the change-order process looks like if something is exposed mid-job. We do all of this as standard practice. Call (866) 650-8319 for a free written estimate that answers all three questions before you sign anything.
Because Pomona’s dominant roof failure mode is wind, not rain. The San Gabriel Valley’s geography funnels Santa Ana gusts off the Cajon Pass, and those winds hit this city harder than most of the LA basin. Rain here is seasonal and relatively light; wind is year-round and relentless. So we select fasteners, nail patterns, and materials based on uplift resistance first. Call (866) 650-8319 if you want an inspection that accounts for Pomona’s actual weather, not a generic checklist.
