- Roof Leak Repair
A leaking roof is not something that can wait. Water that gets through your roofing system can damage insulation, rot decking and framing, promote mold growth, and cause thousands of dollars in interior damage if left unchecked. Texas Star Roofing & Construction provides fast, reliable roof leak repair for homeowners and businesses across San Antonio. With over 30 years of experience, our team finds the source of the leak, fixes it correctly, and makes sure it stays fixed.
Common Causes of Roof Leaks in San Antonio
San Antonio’s climate puts roofs under constant stress. The combination of extreme summer heat, rapid temperature swings, and seasonal hail creates conditions that accelerate wear on every component of your roofing system. These are the most common causes of roof leaks we see in the San Antonio area:
- Cracked or deteriorated pipe boot seals: Rubber boots around plumbing vents are one of the first components to fail in the Texas heat. Once they crack, water runs down the pipe directly into your attic.
- Damaged or missing shingles: Hail, wind, and UV exposure can crack, curl, or strip shingles from the roof. Even one missing shingle creates an entry point for water.
- Failed flashing: Flashing around chimneys, skylights, dormers, and roof valleys can loosen or corrode over time. When it fails, water seeps into the gaps it was designed to protect.
- Clogged gutters and valleys: Leaves and debris trap standing water on the roof surface, which backs up under shingles and into the decking.
- Aging roofing materials: Most asphalt shingle roofs in San Antonio last 15 to 25 years. As materials approach end-of-life, small leaks become more frequent and widespread.
- Storm damage: Hail bruises and wind lift can compromise your roof without visible damage from the ground. Many homeowners do not realize they have a leak until a water stain appears on the ceiling weeks or months after a storm.
What to Do When You Find a Leak
If you notice water stains on your ceiling, damp spots in your attic, or water dripping during rain, take these steps:
- Contain the water. Place a bucket under the drip and move furniture, electronics, and valuables away from the affected area.
- Document the damage. Take photos and videos of the interior damage and any visible exterior issues. This documentation will be important if you file an insurance claim.
- Do not climb on the roof. Wet or damaged roofing is dangerous. Leave the inspection to a licensed professional.
- Call a licensed roofing contractor. A professional can safely locate the source of the leak, assess the extent of the damage, and provide a permanent repair rather than a temporary patch.
If the leak is severe or your roof has been damaged by a storm, contact us for emergency roof repair. We provide same-day emergency tarping to stop water intrusion while a permanent repair is scheduled.
How We Fix Roof Leaks
Our approach to leak repair focuses on finding the actual source of the problem, not just patching the spot where water is showing up. Leaks often travel along rafters and decking before dripping through the ceiling, which means the entry point on the roof can be several feet from where the stain appears inside. Our process includes:
- Thorough interior and exterior inspection to trace the leak to its origin
- Identification of all contributing factors (failed flashing, cracked boots, damaged shingles, poor ventilation)
- Targeted repair using quality materials matched to your existing roofing system
- Full documentation with photos for your records and for insurance if needed
- Post-repair inspection to confirm the fix is holding and no secondary issues exist
In some cases, a leak is a sign of a larger issue. If we find widespread deterioration, storm damage across the full roof, or structural concerns, we will recommend a roof replacement or a full roof inspection rather than a series of spot repairs that will not solve the underlying problem.
Does Insurance Cover Roof Leak Repair?
In many cases, yes. If the leak was caused by a sudden event such as a hail storm, wind damage, or a fallen tree, your homeowner’s insurance policy will typically cover the cost of repair or replacement. However, leaks caused by normal wear and tear, aging materials, or deferred maintenance are generally not covered.
The key to a successful insurance claim is documentation. Our team provides detailed photo evidence and a professional damage report that you can submit to your insurance carrier. We also offer insurance claim assistance to help you navigate the process and advocate for fair coverage. In Texas, you typically have one year from the date of the storm to file a claim, so it is important to act quickly.

Roof Leak Repair FAQ
How much does it cost to fix a roof leak?
Most roof leak repairs in San Antonio range from $300 to $1,200 depending on the source and severity. A simple pipe boot replacement or small flashing repair falls on the lower end, while multiple leak points, damaged decking, or complex flashing work will cost more. We provide a free inspection and a detailed estimate before any work begins, so there are no surprises.
Does insurance pay for a leaky roof?
If the leak was caused by a covered event like hail, wind, or a fallen tree, your homeowner’s insurance will usually cover the repair or replacement. Leaks caused by aging, wear and tear, or lack of maintenance are typically excluded. Filing a claim promptly with professional documentation improves your chances of full coverage. Our team can help you through the process.
Should I call a roofer or a handyman?
Always call a licensed roofing contractor. A handyman may be able to apply a temporary patch, but most lack the training and tools to properly diagnose the source of a leak. Improperly sealed repairs often fail within months and can make the problem worse. A licensed roofer can trace the leak to its origin, make a lasting repair, and provide warranty-backed workmanship.
How do I know if my roof leak is an emergency?
If water is actively dripping into your home, if you see sagging in the ceiling, or if a storm has left visible holes or missing sections of roofing material, treat it as an emergency. Place a bucket under the drip, move valuables away from the area, and call a roofing contractor immediately. We offer same-day emergency tarping to prevent further damage while a permanent repair is planned.
Can a small roof leak cause major damage?
Yes. Even a slow drip can saturate insulation, rot roof decking and framing, and create conditions for mold growth inside walls and ceilings. Over time, what starts as a minor leak can lead to structural damage and expensive interior repairs. The earlier a leak is caught and repaired, the less it will cost to fix.
