Fast, Reliable Roof Repair Across Windcrest
Roof repair in Windcrest usually means one of two things: a leak has already opened up, or you’re looking at hail damage and want it fixed before the next storm rolls through. Either way, you want someone who knows what Windcrest roofs are up against. The mid-century ranch homes here, many still wearing their original 1960s and 70s composition shingles, take a beating from severe thunderstorms tracking along the I-35 corridor. We see the same failure patterns block after block, and we know which repairs actually hold. Call us at (254) 276-4369 for a free estimate, and you’ll know exactly what you’re paying before any work starts.
Why Mercer Roofing Co San Antonio Is Windcrest’s Preferred Roof Repair Company
We’ve repaired enough roofs in Windcrest to know that the difference between a patch and a real fix is usually in what you don’t see: the underlayment, the decking, the flashing behind the siding. Our Roof Repair team works on ranch-style homes, low-slope roofs, and the additions and patio covers that are so common here, and we’ve learned where Windcrest roofs fail first. Every technician who comes to your door is background-checked, identity-verified, and arrives in a clean, marked uniform with a photo ID badge. We send their name and photo before they arrive, because we know that opening the door to a stranger is a real concern for many Windcrest homeowners, especially parents with young kids and older residents who are home during the day. Our crews serve Windcrest directly, and we answer the phone 24/7 with a live person, not a recording.
Styles & brands we work with
Commercial Roof Repair in Windcrest
Commercial Roof Repair in Windcrest covers the flat and low-slope roofs on small offices, retail storefronts, and even the occasional converted ranch home used as a business. Most of the commercial structures here were built in the same 1960s-80s window as the houses, which means the same hail and UV exposure has been working on their modified bitumen or built-up roofing for decades. A commercial repair in Windcrest typically runs $450 to $1,800 depending on the size of the damaged area and whether the membrane needs a patch, a seam repair, or a full recoat around the penetration points.
Flat Roof Patching and Membrane Work
A flat roof patch on a Windcrest commercial building usually involves cleaning the damaged area, applying a compatible membrane patch, and sealing all the laps so standing water can’t find a way in. On older modified bitumen roofs, the seams are often the first thing to fail, and we address those directly rather than just covering the visible split.
Commercial Flashing and Penetration Seals
Every HVAC unit, vent pipe, and conduit that pokes through a commercial roof is a leak waiting to happen. In Windcrest, where severe storms blow rain nearly sideways, the flashing around those penetrations takes a lot of abuse. We replace rusted or lifted flashing and re-seal boots and collars with materials that handle the local weather pattern.
Roof Leak Repair in Windcrest
Roof Leak Repair in Windcrest starts with finding the actual source of the water, which is rarely directly above the stain on your ceiling. Water travels along rafters and sheathing, so a leak near a window might be entering at a vent boot twenty feet away. In Windcrest’s ranch homes, the usual culprits are failed flashing at plumbing vents, cracked shingles from hail impact, and worn-out valley metal. Roof leak repair in Windcrest typically runs $250 to $750 for a single-source leak, and $800 to $1,500 when multiple penetrations need re-flashing and the underlayment has to be replaced in the damaged area.
Vent Boot and Flashing Repairs
The rubber boots around plumbing vents dry out and crack in Windcrest’s intense summer heat and UV exposure, and water seeps in slowly over months. We replace the boot and re-seal the base, and we inspect the flashing around it because on 1960s homes the original metal is often corroded or pulled loose.
Valley and Gable-End Repairs
Valleys catch the most water on any roof, and on Windcrest’s hip and low-slope ranch roofs, a leaking valley is often a sign that the original shingles underneath have degraded past the point of patching. We repair or replace the valley flashing, re-lay the shingles with proper overlap, and make sure the water flows into the gutter instead of under the shingle course.
Trusted Brands We Service in Windcrest
We install and repair Owens Corning, IKO, Atlas, and Tamko shingles, and we keep common Windcrest colors and profiles on hand so a repair doesn’t wait on a special order. If your roof currently wears a 1960s-era 3-tab shingle, we can match it well enough for a patch or talk through a full section replacement with a modern architectural shingle rated for the wind speeds we see here. Manufacturer-recognized materials matter when it comes to the warranty and the insurance documentation that follows a repair.

AfterCommon Roof Repair Problems We See in Windcrest Homes
- Hail fractures on original composition shingles: The 1960s and 70s shingles on many Windcrest ranches were never rated for the hail size that comes through the I-35 corridor. Impact fractures let water in slowly, and the granule loss accelerates fast after the first break.
- Brittle 15-lb felt underlayment: The original felt paper on these homes is now decades old and UV-degraded, which means a shingle patch alone won’t hold back water. The underlayment has to be checked and often replaced in the repair zone.
- Mismatched drip edge on gable eaves: When a previous patch used the wrong drip edge profile, the shingle edges lift under the straight-line winds that come with Windcrest thunderstorms. That’s how blow-offs start along the gable ends on low-slope roofs.
- Failed patio cover and addition flashing: The tie-in where a patio cover meets the house is a weak point on many Windcrest additions. We re-flash those joints with proper step flashing and counter-flashing so water can’t run behind the siding.

FAQs About Roof Repair in Windcrest
A Windcrest roof repair needs to meet the wind-load requirements in the city’s adopted building code, which means the shingles and installation method must carry a rating that matches what the I-35 storm corridor throws at us – typically 110 mph or higher for the products we install. If you’re considering a Roof Installation - Windcrest project instead of a repair, the same wind-load standards apply. Many original 1960s 3-tab shingles don’t meet that today, which is why we recommend impact-rated architectural shingles on repair sections so the whole roof moves toward compliance. We can show you the product’s wind rating on the quote before you approve anything. Call (254) 276-4369 to talk through what your repair would include.
After hail hits a Windcrest roof, the only real way to know is to get into the attic and look at the decking from underneath, then test the wood with a screwdriver or moisture meter for soft spots. Hail fractures in the decking feel spongy when you press on them, and they’ll split open later when wind lifts the shingle edges. If the decking is still solid and dry, you can usually replace the shingles and move on. We check the decking on every repair we quote, and we don’t charge for the inspection.
Windcrest requires a permit for a full roof replacement, and smaller repairs generally move through without one as long as the work doesn’t change the roof structure. The line between repair and replacement matters: if more than about a third of the roof is coming off, the city usually wants it permitted and inspected. We handle the permit paperwork on any job that needs it, and we won’t skip the inspection step just to get done faster.
Because Windcrest’s housing stock is so similar in age and materials – block after block of 1960s and 70s ranch homes with the same composition shingles – one hailstorm hits them all the same way. Roofers who work here regularly can spot recent hail hits just by the pockmarks on aluminum roof vents and AC fins, and when entire blocks take the same damage, insurance adjusters often process multiple claims on the same street in the same week. It’s not unusual to see four or five roofs being repaired on a single Windcrest block after a bad storm. Call (254) 276-4369 if you want a damage assessment while the evidence is still fresh.
The quote should name the specific shingle product and its wind rating, the underlayment spec, and the fastening pattern – not just “replace shingles.” On a Windcrest repair that will pass today’s wind-load check, you’ll see lines for the shingle brand and series, the nailing pattern, the drip edge profile, and any underlayment replacement. If a quote only says “patch roof,” it’s not telling you anything about whether the repair will survive the next straight-line wind event. We put all of it in writing before work starts, including the product’s wind rating and our 365-day guarantee.
If your Windcrest roof has hail damage, a leak, or flashing that’s seen better days, call Mercer Roofing Co San Antonio at (254) 276-4369. We’ll send a background-checked, photo-badged technician whose name and photo you’ll have before they ring the bell, and you’ll get a written price before any work begins. Estimates are free, and the phone is answered by a live person, day or night.
