Fast, Reliable Roof Repair Across Upland
Roof repair in Upland usually runs $350 – $950 for targeted fixes like flashing, vent boots, or shingle replacement, and we can typically schedule Upland homeowners within a few business days of the initial inspection. Millstone Roofing has worked on roofs across 91784, 91785, and 91786 for years, so we know exactly what the San Gabriel foothill sun and Santa Ana winds do to shingles, tile, and flat membranes up here. If you have a leak, missing shingles, or a suspicious water stain, call us at (855) 341-6021 for a straight answer and a free inspection-based estimate. No pressure. No product push. Just documented findings and a repair that fits.
Why Millstone Roofing Is Upland’s Preferred Roof Repair Company
Upland homeowners call us because we do something most roofing companies in the Inland Empire don’t: we inspect first, document what we find, and then recommend repair or replacement based on evidence, not a sales quota. Our Roof Repair team has walked hundreds of Upland roofs, from mid-century ranch homes near Euclid Avenue to 1980s tile roofs climbing into the 91784 foothills. We’ve repaired flashing on downtown bungalows where the original galvanized metal has corroded after 60 years, and we’ve reset wind-stripped tiles along north-facing slopes after Santa Ana events.
Working across seven major manufacturers, including GAF, CertainTeed, and Owens Corning, means we stock a wide range of materials locally and don’t anchor recommendations to one brand. That matters when your 91784 tile roof needs underlayment work but your neighbor’s 91786 ranch needs shingle replacement. One crew, one company, from the first inspection to the final shingle. Nelson Ibarra leads our team with a simple rule: repair when repair is right, replace when replacement makes sense.
Styles & brands we work with
Emergency Roof Repair in Upland
Emergency Roof Repair in Upland is for when a Santa Ana wind event peels back shingles or a sudden winter storm drives water through a failing tile underlayment, and a temporary tarp isn’t enough. In the 91784 foothills, we see emergency calls spike after the first real rain of the season because sun-dried underlayment cracks open under saturated tile. Typical emergency roof repair in Upland runs $450 – $1,200 depending on the number of affected areas, whether we’re replacing underlayment sections, and whether flashing needs immediate renewal.
Storm Wind Response
When Santa Ana winds funnel down from the San Gabriels, they hit north-facing Upland slopes with gusts that lift shingles and tiles whose fastening wasn’t done to spec. Our crews secure the area, document what came loose, and reset or replace the affected materials. Same principle as any Millstone job: we show you what we found before we touch anything.
Leak Triage
Not every wet ceiling needs a full roof replacement. On Upland homes where tile still looks sound from the curb, leaks often trace back to cracked underlayment, failing pipe collars, or worn chimney flashing. We find the actual entry point, not the symptom spot on your ceiling.
Flat Roof Repair in Upland
Flat Roof Repair in Upland tends to concentrate on mid-century ranch homes and the low-slope sections of older downtown properties, where original built-up roofing or early torch-down layers have exceeded their useful life. In the 91785 and 91786 ZIPs, we see flat roofs that dried out over decades of 90-plus-degree summers and now crack, blister, or pond water at the drain points. Flat roof repair in Upland typically costs $500 – $1,500 for localized patches, seam work, and drain-area rebuilds.
Seam and Flashing Repair
Flat membranes fail at seams, parapet walls, and pipe penetrations before they fail in the field. We strip back the damaged section, check the underlying deck for rot, and install a compatible patch using materials matched to your existing system.
Ponding Water Correction
On older Upland flat roofs, low spots develop as framing settles. Standing water accelerates membrane breakdown. We can build up the affected area with a tapered system or re-level the drainage path, depending on what the inspection shows.
Trusted Brands We Service in Upland
We work with seven of the roofing industry’s leading manufacturers, and we stock local parts for Upland customers so you don’t wait on a warehouse to figure out which shingle matches. Whether your roof is CertainTeed architectural shingles, GAF Timberline, or Owens Corning Duration, we can match the existing product and repair it without leaving a patchwork. For Upland homeowners with Boral tiles in the foothills, we source the correct profile and color. The right material for your roof, not the easiest one for us to stock.

AfterCommon Roof Repair Problems We See in Upland Homes
- Dried and cracked tile underlayment in 91784: The tiles look perfectly fine from the street, but the underlayment beneath has baked for decades and lost flexibility. First sustained rain, water gets through, and the ceiling stains begin.
- Wind-stripped shingles on north-facing slopes: Santa Ana winds coming down from the San Gabriels hit those slopes hard. Starter strip and ridge vent fastening that wasn’t to spec fails in sections, leaving granules and torn tabs scattered in the yard.
- Corroded flashing on postwar ranch homes near downtown: Original galvanized flashing at chimneys, skylights, and vents has rotted through on many 1940s and 1950s homes. Drip edge pulls away from fascia, and water wicks into the decking.
- Valley wear at roof intersections: On larger 1980s and 1990s tract homes in 91786, valley metal and woven shingle valleys wear faster than the field. Those are the first points to leak in a steady downpour.

FAQs About Roof Repair in Upland
The underlayment beneath your tile has likely dried out and cracked from decades of intense mountain-edge sun, even though the tiles themselves remain structurally sound. We verify this by lifting tiles at the suspect area and documenting what we find before quoting a repair. Call (855) 341-6021 for an inspection-based answer.
Upland sits at the foot of the San Gabriel Mountains, so north-facing slopes take the direct funneled wind that flatter cities like Ontario see less sharply. We routinely find lifted shingles, stripped ridge vent sections, and tiles shifted by gusts that never registered in Rancho Cucamonga. That’s why our Upland inspections specifically check fastening patterns on windward slopes.
Get written, line-item estimates that name the specific materials and scope, not a verbal number. We inspect first and hand you documented findings with a fixed price. Compare the scope and material, not just the total. Call (855) 341-6021 for an estimate that shows what we found.

Yes. We regularly repair flat and low-slope roofs on the 1940s and 1950s homes around downtown Upland, including membrane patching, seam repair, drain-area correction, and flashing replacement. We’ll tell you if a repair will hold, or if the photo shows the roof is past patching and a replacement makes more sense.
