Why Mercer Roofing Is Selma’s Preferred Roof Repair Company
Selma homeowners have a specific worry when a roof starts leaking: who is actually going to show up at the door. We answer that before you ever open it. Every Mercer technician is background-checked, identity-verified, and dispatched under the Threshold Verified standard, and we send you the technician’s name and photo before the visit. When they arrive, they’ll be in a clean, marked uniform and they’ll present a photo ID badge at the door. That’s the Threshold Standard, and every independently owned Mercer location is contractually held to it.
Mercer Roofing was founded in 2000 and is part of the Threshold Group family of home-service companies. We work on Selma roofs year-round, from the Floral Avenue tract to the neighborhoods off McCall Avenue, and we know what these houses go through. Homeowners along Highway 43 and streets near the Raisin Capital of the World markers call us because our price is always in writing before a single nail is driven. Every repair includes a written guarantee on the workmanship.
Storm Damage Roof Repair in Selma
Storm Damage Roof Repair in Selma usually means one of two things: a heavy wind gust in late spring that lifted a section of shingles on an older roof, or a sudden downpour that found its way through flashing that had been quietly failing for years. On Selma’s shallow-pitch post-WWII homes, the real damage often happens after the storm passes and water has time to pond in a valley or sit against a vent curb. We start every storm repair with a full inspection of the damaged area, a written diagnosis, and a price before any work begins.
Wind-Lifted Shingle Repair
When shingles lift, the seal strip breaks and the next breeze folds them back like a hinge. We remove the damaged shingles, check the underlayment below, and re-set new shingles that match the existing brand and color as closely as possible. On a typical Selma home this runs $350 – $650 for a small section.
Flashing and Valley Sealing After Heavy Rain
If water got in during the last storm, the leak usually traces back to flashing at a valley, chimney, or vent. We replace the failed flashing, clean and re-seal the seam, and test the area with water before we leave. Most flashing repairs in Selma land between $400 and $900 depending on access and the length of the run.
Metal Roof Repair in Selma
Metal Roof Repair in Selma often involves older corrugated panels on carports, patios, and agricultural-adjacent outbuildings, or standing-seam sections on newer additions. The San Joaquin Valley summer heat expands and contracts metal roofing repeatedly, and over years that movement loosens fasteners and breaks down the neoprene washers that keep water out. We replace missing or rusted fasteners, reseal lap joints, and patch panel corrosion before it becomes a hole. Most Selma metal roof repairs run $400 – $1,200 depending on the size of the area and how much fastener replacement is needed.
Fastener and Lap-Joint Resealing
Loose fasteners are the most common metal roof failure we see in Selma. Each screw has a rubber washer under the head, and after enough 105°F summers those washers harden and crack. We replace the fasteners, seal the lap joints, and stop the slow drip before it rots the decking underneath.
Rusted Panel Patch and Corrosion Control
Where panels have rusted through, we cut out the bad section and patch with matching-gauge metal, then treat the surrounding area to slow further corrosion. Selma’s dry-air winters do not rust metal like coastal fog does, but evaporative cooler overflow and irrigation overspray create localized rust zones that deserve attention before the next rainy season arrives.
Trusted Brands We Service in Selma
We repair and install shingle brands including GAF, CertainTeed, Owens Corning, IKO, Atlas, and Tamko, so whatever is already on your Selma roof we can match it. We stock common parts for Atlas and GAF repairs locally and can have most other color-matched products within a day or two. When we replace a section of shingles, the repair is blended so it doesn’t look like a patch job. Call (743) 200-8347 and tell us what brand is on your roof; we’ll bring the right materials to match.
Common Roof Repair Problems We See in Selma Homes
- Raisin-harvest dust damage. Every August through October, Selma rooftops get coated in fine dried-grape dust from the vineyards and packing sheds that surround the city. That abrasive layer grinds granules off aging shingles and packs gutters solid within a single season, which accelerates failure on already heat-stressed roofs.
- Shallow-pitch valley ponding. Most Selma homes built between the 1940s and 1970s have 3:12 or shallower gable roofs. Water moves slowly across them, so standing water in valleys rots flashing and underlayment long before any wind or impact damage appears.
- Rooftop evaporative cooler rot. A large share of older Selma homes have evaporative coolers mounted directly on the decking. Decades of overflow and condensate silently rot the OSB or plank sheathing in a two-to-four-foot radius around each unit, and that damage only becomes visible mid-teardown.
- Tule fog algae and moss. Winter fog can keep relative humidity near 100% for weeks at a time, which feeds algae and moss growth in roof valleys and on north-facing slopes. Selma homeowners rarely expect that in an otherwise bone-dry climate, but we see it every January.

FAQs About Roof Repair in Selma
A tight Selma lot changes our staging, access, and cleanup plan, and that honest reality shows up in the quote. On post-WWII lots where homes sit close together, we may need to stage materials on the front lawn or across the street with neighbor permission rather than in a side yard. If your roof is a low-slope gable with limited ladder access, that adds time. We factor all of it into the written price before work starts, so you are not hit with a surprise line item. Call (743) 200-8347 for an exact quote tied to your lot and your roof.
Yes it does, and we see the proof every fall. The fine dust from Selma’s surrounding vineyards and in-city packing sheds settles on roofs from August through October and works like a low-grade abrasive every time the wind moves it. It grinds granules off shingles that are already baking in 105°F summer temperatures, and it packs gutters so tightly that water backs up onto the eaves. A roof that might last 25 years on California’s coast can lose several years of life in Selma’s harvest cycle without regular inspection and gutter cleaning.
Typically a two-to-four-foot radius around the cooler unit, and we won’t know the true extent until we strip the shingles in that area. On Selma homes with rooftop evaporative coolers, we routinely find OSB or plank sheathing that has been quietly rotting for years from overflow splash and condensate. We replace the damaged decking, re-flash the cooler curb, and lay new underlayment before putting shingles back on. We’ll show you photos of the damage before we replace anything, and the price for extra decking is already part of your written quote.
Because your roof was likely built with a 3:12 or shallower pitch, meaning water travels slowly and sits in the valley longer than it would on a steeper roof. Over time, that standing water works through the flashing and underlayment. On these older Selma homes, the fix is usually not just patching the valley; it’s replacing the flashing and adding a properly sealed underlayment barrier underneath. We explain exactly what we found and write down exactly what we’ll do, before any work begins. Call (743) 200-8347 for a free inspection of your valleys.
We tell them what is happening before we start, and we keep the site clean throughout the job. On tight Selma lots where a ladder or material staging touches a shared side yard, our crew introduces themselves, explains the timeline, and gives the neighbor a direct line to reach us if anything feels disruptive. We clean up every day before leaving and do a final magnet sweep for nails at the end of the job. We also follow Selma’s noise and work-hour rules, which matters when homes sit close together. A roof repair should not become a neighborhood headache, and we plan so it does not.
