Most roof repairs in Mendota run between $350 and $1,200, and our crews can typically inspect your roof within 24 to 48 hours of your call.

We’re Crestview Roofing, part of the Relay Home Co. family, and we’ve been dispatching crews to Mendota from our Fresno office since we built our Central Valley operation. Dylan Pace leads our team, and we know the difference between a roof that’s taken a beating from Mendota’s 110-degree Julys and one that’s dealing with the occasional winter tule fog that traps moisture against north-facing slopes. Our Roof Repair technicians are background-checked, uniformed, and trackable on arrival. Call (325) 246-5075 to schedule your free estimate.

Metal Roof Repair in Mendota
Metal Roof Repair in Mendota addresses the screw-line leaks, panel separations, and rust spots that develop on agricultural buildings and the growing number of residential metal roofs around town. Mendota’s combination of intense UV exposure and seasonal thermal expansion puts unique stress on fastener seals. A typical metal roof repair here runs $450 to $1,800 depending on whether we’re resealing a few seams or replacing corroded panels near the drip edge.
Fastener and Seal Replacement
The neoprene washers under metal roof screws harden and crack after about 10 to 15 years in Mendota’s sun. We remove the old fasteners, install oversized screws with fresh EPDM washers, and seal the penetrations with a compatible sealant rated for high-temperature cycling.
Panel Overlap and Flashing Work
When metal panels shift at their overlaps, water runs downhill and pools at the lap joints. We open the seam, clean out any debris or failed butyl tape, and reinstall with proper sidelap sealant. At wall transitions and pipe penetrations, we fabricate custom Z-flashing or use preformed boots that match your panel profile.
Commercial Roof Repair in Mendota
Commercial Roof Repair in Mendota covers the flat and low-slope roofing systems on warehouses, packing sheds, retail buildings, and small office structures throughout the city. Mendota’s commercial stock includes aging built-up roofs on older downtown buildings near Derrick Avenue and newer TPO or modified bitumen systems on industrial properties along the Highway 180 corridor. Typical commercial repairs range from $800 for a targeted membrane patch to $4,500 for extensive flashing reconstruction or drain replacement.
Membrane Patching and Weld Repair
We cut out damaged TPO or PVC membrane, prep the substrate, and hot-air weld a new patch that extends at least 6 inches past the damage in all directions. For EPDM rubber roofs, we use pressure-sensitive adhesive patches with factory-applied seam tape for a chemical bond that holds up to Mendota’s temperature swings.
Drain and Scupper Restoration
Clogged or improperly flashed roof drains cause the ponding water we see too often on Mendota commercial buildings. We clear the drainage path, replace rusted cast iron bodies with coated aluminum or PVC where appropriate, and install new clamping rings with proper two-ply membrane collars.
Trusted Brands We Service in Mendota
We repair roofs built with GAF Timberline and Royal Sovereign shingles, CertainTeed Landmark and XT 25 lines, Owens Corning Duration and Oakridge products, and IKO Cambridge and Dynasty shingles. Our Fresno warehouse stocks common repair components for these brands, which means we’re not ordering parts and making you wait while a leak spreads across your ceiling. For flat roof systems, we carry compatible accessories for the major single-ply and modified bitumen manufacturers. When we recommend Roof Replacement in Mendota instead of another repair, it’s because the material math genuinely doesn’t work, not because we’re pushing a bigger sale. Every recommendation comes with a written explanation and photos you can review on your phone.
Common Roof Repair Problems We See in Mendota Homes
- Valley leaks on post-war ranch homes. The original 1950s and 1960s ranches near the older grid east of Derrick Avenue often have galvanized steel valleys that have corroded through. We replace them with prefinished aluminum or W-profile valleys that handle Mendota’s occasional heavy winter rains without backing up.
- Granule loss from thermal shock. Shingle roofs in Mendota experience daily temperature swings of 40 to 50 degrees during summer. The asphalt expands and contracts, loosening ceramic granules and exposing the mat underneath. We spot-replace shingles before UV degrades the bare asphalt and cracks the mat.
- Wind lift along the San Joaquin River corridor. Properties closer to the river channel get channelized afternoon winds that can peel back shingle tabs, especially on three-tab roofs installed before 2010. We secure lifted tabs with asphalt plastic cement and replace any that have torn at the sealant strip.
- Vent boot deterioration. The rubber collars around plumbing vents harden and crack after 8 to 12 years in Central Valley sun. We install new two-piece EPDM boots or lead replacements that flex with pipe movement and seal against the flange.
