Our Roof Repair team works on Kirby roofs week in and week out. We know which neighborhoods have the thinner 1960s decking, which low-slope sections need extra attention at the eaves, and what the HOA in newer master-planned communities requires before anyone touches a shingle.

If the repair fails within 365 days, we come back and make it right under our 365-Day Done Right Promise.
Styles & brands we work with
Roof Leak Repair in Kirby
Roof Leak Repair in a 1960s Kirby ranch usually traces to a few known culprits: rusty nail pops through 3/8-inch decking, dried-out vent boot gaskets, or failing flashing where the carport ties into the main roof. The fix typically costs $275 – $600 depending on how many spots need work and whether any decking has rotted. Leaks on newer homes off Old Seguin Road or in the master-planned communities tend to come from builder-grade flashing or underlayment that failed early, not from age. Those repairs generally run $350 – $800.
Nail Pop Sealing
Nail pops happen when the plywood decking is too thin for the fasteners to bite. The nail backs out, lifts the shingle above it, and water finds the hole. We pull the lifted shingle, reset or replace the fastener, seal the penetration, and resecure the shingle so it lays flat again.
Vent Boot and Flashing Replacement
The rubber boot around your plumbing vent cracks after 15 – 20 years of Texas sun. When it does, water runs straight down the pipe into your attic. Replacing a vent boot on a Kirby home costs $225 – $425. Flashing repair around chimneys, skylights, or wall junctures runs $300 – $750 depending on access and how much of the old metal needs to come out.
Emergency Roof Repair in Kirby
Emergency Roof Repair in Kirby usually means wind lifted a section of shingles during a spring storm, hail punched through an aging roof, or a limb came down and opened a hole. Pricing for emergency work runs $350 – $950 depending on the size of the damage and whether we need to tarp first. A live person answers our phone 24/7, and we dispatch crews to Kirby from our San Antonio office as soon as we know what you’re dealing with.
Storm Damage Tarping
When wind rips shingles off a low-slope ranch roof, water enters fast. We often tarp first to stop the bleeding, then come back for the permanent repair once the weather clears and materials are staged. Tarping runs $200 – $400, and that’s always included in your written estimate before we start.
Hail Impact Assessment
Kirby sits in a natural hail corridor. Spring storms send stone down hard enough to bruise shingles, knock granules loose, and crack the mat underneath. You won’t always see the damage from the ground. We inspect the whole roof, mark every impact point, and document it for your insurance claim if you file one.
Trusted Brands We Service in Kirby
We repair and install shingles from GAF, CertainTeed, and Owens Corning, which covers the vast majority of what’s already on Kirby roofs. If your HOA requires a specific architectural profile or color, we can match it from those lines. We also work with Boral and other manufacturers when the job calls for it. Because we run jobs through Kirby regularly, we can usually source matching materials faster than a company that rarely works this side of the Loop. That speed matters when a bare spot on your roof is waiting on shingles that have to be special-ordered.

AfterCommon Roof Repair Problems We See in Kirby Homes
- Recurring nail pops on pre-1970s ranch roofs. The original 3/8-inch decking simply doesn’t hold fasteners the way modern 7/16-inch or 1/2-inch plywood does. We see this constantly on the east side of Kirby near Ackerman Road and Binz-Engleman. The fix requires more than driving a nail back down; the decking often needs localized replacement.
- Wind-lifted shingles along low-slope eaves. Older ranch homes in Kirby were built with shallow pitches that catch wind at the edges. When the starter strip rots or the original fasteners corrode, whole sections peel up. Replacing the starter course and resecuring the field is a common $400 – $700 repair.
- HOA color-match failures on newer infill homes. Master-planned sections of Kirby have architectural review boards that approve shingle colors and profiles. A repair that doesn’t match gets red-tagged. We pull HOA docs before we order materials so you’re not paying for a second repair.
- Undersized attic ventilation on 1990s and 2000s builds. Newer Kirby homes often used builder-grade ridge vents or none at all. That trapped heat cooks shingles from below, accelerating granule loss. Adding proper ventilation during a repair costs $150 – $450 and extends the life of the whole roof.

FAQs About Roof Repair in Kirby
Because the original decking is too thin. Pre-1970s homes in Kirby, especially east of Ackerman Road and around Old Seguin Road, were built with 3/8-inch plywood that doesn’t hold fasteners well after decades of heat cycling and minor foundation movement from the area’s clay-rich soils. Patching the shingle without addressing the decking means the nail will back out again. The permanent fix is replacing the affected decking section with modern thickness plywood, then resecuring the shingles. On a 1960s ranch off Ackerman Road, our crew found a leak above the carport traced to exactly this: rusty nail pops through 3/8-inch decking. We pulled the lifted architectural shingles, replaced a four-foot section, added ice and water shield along the low-slope edge, and resecured the field with a starter strip and correct nail pattern. Call (254) 276-4369 and we’ll assess your decking before quoting.
It can, if the repair isn’t documented or doesn’t match the original installation. Many builder warranties on Kirby’s 1990s and 2000s homes contain clauses about workmanship and materials. A repair that changes the shingle profile, uses a different nail pattern, or modifies the underlayment can give the builder grounds to deny a future claim. Our technicians document every repair with photos, material specs, and a written description of work performed. We also check HOA architectural guidelines before ordering materials on newer infill homes. On that Ackerman Road job, the homeowner’s builder warranty had lapsed, but we documented every step for the HOA’s architectural review anyway. If your warranty is still active, we’ll tell you what your repair does and doesn’t affect before we start. Call (254) 276-4369 for a written assessment.
Yes. We match GAF, CertainTeed, and Owens Corning architectural shingles to the manufacturer’s current color codes, and we keep common Texas profiles in our supply network for faster turnaround in Kirby. Before we order anything, we pull your HOA’s current architectural guidelines and confirm the exact color and profile requirement. If the specified color has been discontinued, we find the closest approved substitute and document it with the association. Standard shingle replacement on a Kirby home with HOA-matched architectural shingles runs $425 – $950 depending on the section size. Call (254) 276-4369 and have your HOA docs handy.
Low-slope roofs in Kirby, especially shallow-pitch ranch homes from the 1960s and 70s, almost always need ice and water shield at the eaves and valleys. Standard underlayment works on steeper roofs where water runs off quickly. On low slopes, wind-driven rain pushes water uphill under the shingles, and that’s when regular felt fails. Ice and water shield is a self-sealing membrane that bonds to the decking and seals around nail penetrations. We install it as standard on any low-slope repair in Kirby that touches the eaves or a valley. The material add runs $150 – $400 depending on the section length, and it prevents the exact leak pattern that shows up after Kirby windstorms. Call (254) 276-4369 and we’ll inspect your slope during the free estimate.
Check whether the lifted shingles exposed the underlayment, then call (254) 276-4369 before rain gets under the roof. The first thing we look for when we arrive is whether the fasteners actually held or whether the decking let go. On Kirby’s eastern pre-1970s neighborhoods, thin decking and fewer fasteners mean lifted shingles are often a sign that the wood underneath has failed, not just the shingle seal. If the decking did hold, we can usually resecure the shingles and seal the exposed area for $350 – $600. If the decking needs replacement, the job is bigger but still manageable. We’ll tarp if needed and give you a written price before any work starts.
