What Our Flashing Repair Includes

Roof Flashing Repair in San Marino, Texas
Flashing is the cheapest part of your roof to fix and the most common reason it leaks. Fix it properly once and you stop chasing stains for years.
Roof Flashing Repair in San Marino, Texas is the trade of resealing, re-securing or replacing the metal and membrane pieces that waterproof roof transitions. Flashing covers the joints where your roof meets a chimney, wall, skylight, vent pipe or valley. It also includes step flashing along sidewalls and counter flashing set into masonry. When those pieces lift, crack or corrode, water bypasses the shingles entirely and finds the deck.
San Marino sits in a hail-and-wind corridor, so flashing takes a beating. We see pipe boot cracking, chimney flashing leaks and metal panel seam leaks after nearly every spring storm. Homeowners call us when a ceiling water stain shows up weeks later. If you need roof flashing fixing San Marino wide, we start with a free inspection and tell you exactly which joint failed.

How Our Flashing Repair Process Works
We keep it simple: find the failure, show you what we found, fix it right, and prove the repair holds.
Tools and Methods We Use
Each method answers a different question. Together they leave very little to guess.
Shows temperature differences from hidden moisture behind ceilings and in attic spaces, which helps locate leaks that are not visible from the roof.
Lets us photograph steep or tall roof sections safely and document flashing condition without putting a tech on a dangerous slope.
Detects moisture through membranes and underlayment on flat and low-slope roofs where visual inspection is not enough.
Applies controlled water over a repaired flashing detail so we can verify the fix while a second tech watches inside.
When You Need Flashing Repair
You see a ceiling water stain after a storm and the attic sheathing is damp near the chimney.
We inspect the chimney flashing first, since that is the most common source.
HomesYour roof is 12 years old and the pipe boots are visibly cracked and brittle.
We replace every cracked boot on the roof in one visit, matched to your pipe sizes and roof material.
HomesA hail storm dented your metal flashing and broke the seal at the valleys.
We document the hail damage, replace the dented flashing, and reseal the valley details.
HomesYou are selling your home and the buyer's inspector flagged flashing at the chimney and skylight.
We repair both transitions, hose-test them, and provide a written summary with photos.

How Flashing Repair Runs in San Marino
San Marino sits in a hail-and-wind corridor, so flashing takes more abuse here than in most of Texas. Spring storms dent metal, lift step flashing and crack pipe boots. Summer heat then bakes the sealant until it fails.
Monte Vista
Older homes with clay tile and complex roof lines. Chimney and valley flashing failures are common after storms.
Stone Oak
Steep architectural shingle roofs with multiple pipe penetrations. Pipe boot cracking is the most frequent call here.
Southtown
A mix of historic and renovated roofs. Step flashing along sidewalls often needs resetting after wind events.

PhotoChimney Flashing Leak Stopped
Before: A homeowner in Monte Vista had a ceiling stain that returned after two prior reseals. The counter flashing was never set into the masonry, so water ran behind it every storm.
After: We reset the counter flashing, replaced the step flashing, and hose-tested the chimney. The attic stayed dry through the next three storms. The repair took four hours.
Cracked Pipe Boots Replaced
Before: A Stone Oak home had four pipe boots cracked from UV exposure. Two were already leaking into the attic insulation, though no ceiling stain had appeared yet.
After: We replaced all four boots in under three hours and hose-tested each one. The attic insulation dried out and no stain ever developed.
Valley Leak Fixed on Tile Roof
Before: A Southtown tile roof had a valley leak that three other companies missed. The valley flashing had corroded through, and water was running under the tile field.
After: We lifted the tile, replaced the valley flashing, and reset every piece without cracking one. The repair took a full day and passed a two-hour hose test.
Flashing Problems We Fix in San Marino
Most of the roof leaks we repair in San Marino trace back to one of these flashing failures.
Chimney flashing leaks after heavy rain
Water runs down the chimney into the attic and stains the ceiling below. Left alone, it rots the sheathing and framing around the chimney.
Cracked pipe boots leaking down vent pipes
A cracked boot lets water run straight down the pipe into insulation and drywall. It often shows up as a stain far from the actual pipe.
Lifted step flashing along sidewalls
Wind uplift pulls step flashing away from the wall, opening a gap that lets water behind the shingles.
Skylight flashing leaks
Skylight flashing failures drip directly onto the ceiling and can damage the skylight frame. They are easy to miss until the stain appears.
Why Fix Flashing Before Anything Else
Flashing failures cause most of the roof leaks we see in San Marino, and they are the cheapest leaks to stop early.
Stops the Leak at the Source
Water that gets past failed flashing soaks your sheathing and insulation before it ever shows on the ceiling.
Protects Your Shingle Warranty
A failed chimney flashing leak can void coverage on an otherwise healthy roof.
Handles Hail and Wind Damage
Hail dents and wind uplift damage bend step flashing and tear pipe boots loose.
Extends Roof Life for Years
A roof with sound flashing routinely outlasts one with chronic leaks by five to eight years.
What Flashing Repair Costs
A single pipe boot replacement sits at the low end. Chimney or valley flashing with tile removal runs higher.

What San Marino Neighbors Say
We had a ceiling stain that kept coming back after two other roofers resealed the chimney. This crew found the counter flashing was never set into the masonry. They reset it, replaced the step flashing, and hose-tested it while I watched from the attic. No leak after the last two storms.
Our clay tile roof had a valley leak that three companies missed. They lifted the tile carefully, repaired the valley flashing, and reset every piece without cracking one. The price matched the quote and they cleaned the gutters before leaving. I have already recommended them to two neighbors.
We manage six buildings and flashing leaks were eating our maintenance budget. They replaced cracked pipe boots on all six roofs in one day and documented every repair with photos. The attic stays dry now and I have a record for the owner.
Frequently Asked Questions About Flashing Repair
Short answers for the first few minutes. The team can cover the rest.
Describe what you are seeing and we will point you to the right next step.
2109395773A single pipe boot replacement sits at the low end; chimney or valley flashing with tile removal runs higher. We quote the price after inspection, and the number does not change unless you approve added work.
Yes. We serve San Marino and the surrounding San Antonio neighborhoods, and we carry the common flashing materials on every truck. Call 210-939-5773 and we can usually inspect the same day. If the leak is active, we tarp or seal it first so the damage stops spreading.
A single transition takes two to four hours including the hose test. A chimney plus two pipe boots plus a valley can run a full day. We tell you the expected window when we quote, and we do not leave a repair untested.
The three most common causes we find are pipe boot cracking from UV, lifted step flashing after wind uplift, and failed sealant at counter flashing. Hail dents metal and breaks the seal at the same time. A moisture meter and infrared camera confirm which joint failed before we replace anything.
