What Our Skylight Leak Repair Includes
Every skylight job starts with a full inspection and a confirmed leak source. From there, the scope depends on what we find at the curb, flashing, and deck.
Work order
Skylight Leak Repair- Full Skylight Inspection: We inspect the curb, flashing, glass seal, fasteners, and the surrounding shingles or membrane. Inside, we check the attic with a moisture meter and thermal camera to map how far the water has traveled.
- Hose Test Confirmation: Before we open anything, we run water at the skylight and watch from inside. That confirms the entry point and rules out a nearby chimney flashing leak or pipe boot cracking that would otherwise get blamed on the skylight.
- Flashing and Sealant Replacement: We remove failed sealant and butyl tape, replace damaged step and counter flashing, and re-bed the curb with Henry Company or Sika sealant rated for Texas roof temperatures.
- Fastener and Curb Repair: Backed-out or rusted fasteners get replaced with correct-length roofing screws. If the curb wood is soft, we cut out the rot and sister in new lumber so the flashing has something solid to bite into.
- Final Water Test: We flood the skylight one more time and confirm it is dry inside.

What Skylight Leak Repair in San Marino, Texas Covers
A skylight leak gets worse with every storm. Fixing the flashing and curb correctly the first time keeps your ceiling, insulation, and framing dry.
Skylight Leak Repair in San Marino, Texas is the trade of sealing the four places a skylight fails: the curb, the flashing, the glass seal, and the frame fasteners. Water almost never comes through the glass itself. It gets in at the curb where the unit meets the roof deck, or where old flashing has pulled away from the shingles. We open the surrounding courses, replace the failed sealant and butyl tape, and rebuild the flashing so the unit sheds water the way it did the day it was set.
Most San Marino skylight leaks we see start as a brown ring on the ceiling, then a drip during the next storm. By the time the drywall sags, water has been running down the rafter for weeks. That is why we treat skylight leak fixing San Marino calls as urgent, not cosmetic. If you are searching for skylight leak fixing near me San Marino Texas, we cover the whole city and the surrounding Bexar County neighborhoods.

Tools and Methods We Use
Each method answers a different question. Together they leave very little to guess.
Gives a numeric reading on drywall, insulation, and framing. Anything above 20 percent means active moisture and tells us how far the damage has spread.
Detects moisture through roofing layers without tearing anything open. Useful on membrane and flat roofs where a pinhole leak is hard to see.
Applies controlled water at the skylight while a second technician watches inside. This is how we confirm the entry point instead of guessing.
Photographs steep or fragile roofs, including slate and clay tile, without putting a person on the surface. It gives us a clear look at the skylight curb from every angle.

How Skylight Leak Repair Runs in San Marino
San Marino sits in Bexar County where the roof takes a beating: hail in spring, 100-degree summers, and hard driving rain in the fall. That cycle dries out sealant and works fasteners loose at skylight curbs faster than in milder climates.
Monte Vista
Historic homes with clay tile and steep pitches. Skylights here are often original, and the flashing has been patched repeatedly. We handle tile carefully and rebuild the curb flashing to match the profile.
Stone Oak
Newer construction with architectural shingles and larger skylights. Hail damage to flashing is common here, and we document it with photos for insurance claims.
Terrell Hills
Mix of slate, tile, and shingle roofs on larger lots. Steep access means we use roof hooks and harnesses, and we drone-inspect before committing anyone to the surface.

PhotoMonte Vista Ceiling Stain Stopped
Before: A homeowner had a 14-inch brown ring on the ceiling under a curb mounted skylight. The previous owner had smeared caulk around the frame twice. A moisture meter read 24 percent in the drywall and the flashing had pulled away on the north side.
After: We removed the old caulk, replaced the butyl tape and step flashing, and re-bed the curb with high-temp sealant. The final hose test ran clean. Moisture readings dropped to 11 percent after three days of drying.
Stone Oak Commercial Skylight Reflashed
Before: A tenant reported a drip from a large commercial skylight during business hours. The TPO membrane flashing at the curb had separated from the unit, and ponding water was sitting against the seam after every rain.
After: We re-welded the membrane flashing, added a new termination bar at the curb, and cleared the nearby roof drain. The tenant stayed in the space the whole time. Two follow-up storms produced no leaks.
Terrell Hills Hail Damage Repair
Before: Hail dented the skylight flashing and cracked the dome on a 1990s home. Water was dripping into the attic and soaking insulation around the light well. The homeowner needed documentation for an insurance claim.
After: We tarped the unit the same day, returned after drying, replaced the flashing and dome, and replaced the wet insulation. The photo set went to the adjuster with the claim. Attic moisture returned to normal within a week.
Skylight Leak Problems We Solve in San Marino
Skylight leaks show up in a handful of predictable ways.
Ceiling water stains spreading under the skylight
Drywall softens, paint peels, and mold can colonize within 48 to 72 hours of continuous moisture. Left alone, the stain grows and the ceiling may sag.
Attic water intrusion soaking insulation
Wet blown-in insulation compacts and loses R-value, and framing lumber above 20 percent moisture invites rot. Your energy bills climb while the damage spreads.
Skylight flashing leaks after heavy rain
Once the metal pulls away from the curb, every storm pushes water straight into the roof assembly.
Cracked or dried sealant around the frame
UV exposure bakes standard caulk until it cracks and pulls away.
Why Fix a Skylight Leak Now
A leaking skylight does not heal itself, and San Marino's spring hail and summer downpours push water through every gap.
Stop Ceiling Damage Cold
Every hour water sits above your ceiling, it spreads through the drywall and insulation.
Protect Attic Insulation
Wet blown-in insulation loses its R-value and compacts into a mat. One skylight leak can soak a 4-foot radius of attic floor.
Keep the Skylight You Paid For
Repair usually costs a fraction of that.
Avoid Mold and Rot
Framing lumber stays wet above 20 percent moisture and mold colonizes within 48 to 72 hours.
What Skylight Leak Repair Costs
A simple flashing reseal sits at the low end. Curb rebuilds, rotted decking, or interior drywall repair push the number higher.

What San Marino Customers Say
We had a brown ring on the ceiling under our skylight for two months and kept putting it off. These guys found the flashing had pulled loose on one side. They replaced the butyl tape and resealed the curb in about three hours. Next storm, no drip. They also swept the yard for nails, which my dog appreciated.
I manage four buildings with skylights and had two leaking into tenant spaces. Their tech used an infrared camera in the attic and showed me exactly where the water was tracking. Turned out one was a skylight and one was a vent boot. Fixed both the same visit. Clean work, fair invoice.
Our skylight leaked during a hailstorm and I called at 7 a.m. They were on the roof by 10. Tarped it, came back two days later when it dried out, and did the flashing repair. They gave me photos of the hail dents for my insurance claim. That saved me a lot of arguing with the adjuster.

Yes. We cover all of San Marino and the surrounding Bexar County neighborhoods, including Monte Vista, Alamo Heights, Stone Oak, and Terrell Hills. Call 2109395773 with your address and we will confirm the visit window. Same-day Skylight Leak Repair San Marino appointments are common when you call before noon.
A standard skylight leak repair takes two to four hours on site. That includes inspection, hose testing, flashing replacement, and a final water test. If the decking under the curb is rotted, add a half day for sheathing repair and drying. We tell you the expected duration when we confirm the job.
Nine out of ten skylight leaks we open are flashing failures, not glass failures. UV exposure dries out the sealant, the butyl tape under the flashing shrinks, and fasteners back out from thermal movement. San Marino's hail and wind uplift damage speed that up. A moisture meter and hose test confirm the exact entry point before we repair.
