What's Included in Our Attic Leak Repair
Every attic leak repair includes the full detection and verification process, not just the patch.
Work order
Attic Leak Repair- Full Leak Detection: Infrared thermal imaging camera scan of the attic deck, moisture meter readings at suspect points, and a visual roof inspection of flashing, boots, valleys, and penetrations. This is how we find the source instead of guessing at the stain.
- Source Repair: Replacement or repair of the failed component: pipe boot, roof flashing, underlayment section, valley, or shingle. We use matched materials and correct sealants so the repair holds through thermal movement and the next storm.
- Hose Test Verification: A controlled water test over the repaired area with a technician watching from inside the attic. If water still appears, we keep working. This step is what separates a real repair from a hopeful patch.
- Photo Documentation: Before and after photos of the failed component and the finished repair, plus moisture readings.
- Cleanup and Debris Removal: We haul off replaced material, clean the work area, and leave the attic and roof in the condition we found them, minus the leak. No nails in the yard, no debris left on the roof.

What Attic Leak Repair in San Marino, Texas Covers
An attic leak is not a cosmetic problem. Left alone, it soaks insulation, rots sheathing, and stains the ceiling below. Fixing it properly the first time is cheaper than fixing it twice.
Attic Leak Repair in San Marino, Texas is the diagnosis and permanent repair of water entering your home through the roof deck, flashing, or penetrations above the living space. Water rarely lands where it enters. It rides a rafter, soaks insulation, and shows up as a ceiling stain six feet away. We trace it back with an infrared thermal imaging camera and a moisture meter, then fix the source instead of the symptom.
San Marino sits in Bexar County, where roofing takes a beating from hail, wind uplift, and summer attic temperatures that push past 140 degrees. That heat cooks pipe boots and roof sealant until they crack, and the next storm finds the gap. If you have been searching for attic leak fixing near me San Marino Texas after a wet ceiling, we handle the whole job: locate, repair, and verify with a hose test before we pack up.

How Our Attic Leak Repair Process Works
Five steps, no mystery. Here is exactly what happens from the phone call to the final hose test, and roughly how long each stage takes.
Tools and Methods We Use
Each method answers a different question. Together they leave very little to guess.
Confirms moisture content in sheathing, rafters, and insulation so we know the leak is active and how far the water has spread.
Detects moisture through roofing layers without tearing the roof apart, which keeps the repair small and targeted.
Lets us inspect steep, fragile, or tall roofs, including clay tile and slate, without putting weight on materials that crack easily.
Applies controlled water over the repaired area while we watch from inside the attic, confirming the fix before we leave the property.

How Attic Leak Repair Runs in San Marino
San Marino roofs deal with a specific combination: hail season in spring, wind uplift from summer storms, and attic temperatures that regularly exceed 140 degrees.
Monte Vista
Historic homes with clay tile and original sheathing. We use a roof inspection drone and careful footing to avoid cracking tile that is hard to match.
Stone Oak
Newer architectural shingle roofs that leak most often at valleys and flashing details after hail and wind events.
Beacon Hill
Older homes where pipe boots and chimney flashing have taken decades of UV and heat damage. Boot replacement is the most common fix.

PhotoCracked Pipe Boot in Monte Vista
Before: A homeowner had a growing ceiling stain above the hallway. Two previous companies recommended a full roof replacement. Our inspection found a cracked rubber pipe boot on a vent penetration, with water running down the pipe and soaking the insulation around it.
After: We replaced the boot with a UV-resistant unit, sealed the collar, and hose tested the penetration. The repair took under two hours. The ceiling stain stopped growing, and the homeowner saved thousands against the replacement quotes.
Valley Leak in Stone Oak
Before: After a hail storm, water started dripping into the attic above a bedroom. The valley underlayment had failed, and water was traveling along a rafter before dripping several feet from the actual entry point, which made it hard to trace.
After: We opened the valley, replaced the failed underlayment, rebuilt the valley to drain correctly, and hose tested the repair. The attic stayed dry through the next storm, and the ceiling was repaired and repainted.
Chimney Flashing Rebuild in Beacon Hill
Before: An older home had water entering the attic around the chimney every time it rained hard. The step flashing had rusted through and the counter flashing had pulled away from the masonry, leaving an open path for water.
After: We rebuilt the step and counter flashing with proper laps, resealed the joint, and verified with a hose test. The attic dried out, and the homeowner avoided the framing rot that was starting to develop around the chimney.
Attic Leak Problems We Solve in San Marino
Most attic leaks trace back to a short list of failures.
Ceiling water stains that keep growing after rain
Each rain cycle spreads the stain, saturates insulation, and eventually softens drywall until it sags or collapses. Mold can establish within 48 hours of sustained moisture.
Cracked pipe boots letting water run down vent pipes
UV exposure and attic heat harden rubber boots until they split.
Chimney flashing leaks during hard rain
Failed step or counter flashing sends water directly into the attic framing around the chimney.
Valley leaks from failed underlayment
Valleys carry the most water on the roof.

What San Marino Homeowners Say
We had a brown ring on the ceiling for two weeks and two other companies told us we needed a full roof replacement. These guys went in the attic with a camera, found a cracked pipe boot in about ten minutes, and had it replaced the same afternoon. The hose test at the end sold me. No leak since, and the price was a fraction of what we were quoted.
After the last hail storm, water started dripping into our attic above the garage. They documented everything with photos, repaired the flashing and a section of underlayment, and gave us the images for our insurance claim. The adjuster actually commented on how clear the documentation was. Ceiling is dry and the stain is gone.
I manage several older rental properties, and attic leaks are the calls I dread. This crew traced a valley leak on a 1940s house that had been misdiagnosed twice. They replaced the underlayment, rebuilt the valley, and tested it before leaving. Tenants stopped calling. I have them on speed dial now for all my roofs.

2109395773A single pipe boot replacement sits at the low end. Chimney flashing rebuilds, valley repairs, and jobs that require new underlayment land higher. Emergency or after-hours calls add a premium. We give you the number before we start, and the inspection findings drive it, not a flat rate.
Yes. We cover San Marino and the surrounding San Antonio area, including Monte Vista, Beacon Hill, Stone Oak, Alamo Heights-adjacent streets, and the Southside. Call 210-939-5773 and describe what you are seeing. If water is actively coming in, we treat it as priority and get a technician out to stop it before it spreads into insulation and drywall.
The inspection takes 45 to 90 minutes. The repair itself usually runs two to four hours for a single-source leak, including the hose test. Larger jobs, like a valley with failed underlayment or a chimney flashing rebuild, can take a full day. We tell you the expected window when we scope the work, so you can plan your day.
Start inside the attic on a rainy day with a flashlight, and look for dark streaks on the deck, rusted nails, or sagging insulation. Water travels along rafters, so the wet spot is often not below the entry point. If you cannot pin it down, we use an infrared thermal imaging camera and a moisture meter to read the deck and trace it back to the flashing, boot, or valley that failed.
