Chimney Flashing Repair in San Marcos
Flashing is the metal-and-sealant barrier where the chimney meets the roofline. It's the #1 source of chimney leaks. Proper flashing uses step flashing, counter-flashing set into the mortar, and a watertight seal — not just a smear of tar.
Why this matters in San Marcos
San Marcos blends the Texas State university district and historic square with new Blanco Vista and Kissing Tree growth. Older masonry repointing meets prefab cap-and-chase service, with Hill Country freeze events adding crown work. That local stock is exactly why our San Marcos crews tailor chimney flashing repair to the homes here — not a generic checklist.
Common signs in San Marcos homes
- Water stains on the ceiling or wall near the chimney

Chimney Flashing Repair in San Marcos — FAQ
How do I know the leak is coming from the flashing?
Flashing leaks usually show as ceiling or wall stains around the chimney, damp or rotted framing in the attic near the chimney, and rust streaks at the roofline. Because water travels along framing before it drips, a proper diagnosis rules out the crown, cap, and masonry before blaming the flashing.
Can't I just seal it with caulk or roofing tar?
A bead of sealant is a short-term patch that usually cracks and fails within a season or two. A lasting fix is layered step flashing and counter-flashing woven into the shingle courses and locked into a cut mortar joint, not surface goo over the top of a failed assembly.
What happens if I ignore a flashing leak?
Ongoing water intrusion rots roof decking and framing, soaks insulation, stains drywall, and feeds mold, and it can also break down the chimney masonry from the inside. The longer it runs, the more hidden structure has to be replaced, and the repair cost climbs sharply.
How long does flashing repair take?
Most flashing repairs finish in a few hours to a day, depending on roof pitch, chimney size, and whether rotted decking is found underneath. Steep roofs and replacing damaged sheathing add time, and hidden water damage is the main reason a job runs longer than quoted.
Does new flashing come with any guarantee it won't leak again?
Reputable installers warranty their flashing work, and properly woven step-and-counter flashing should keep the roofline dry for many years. Ask that the quote spell out the materials, the layering method, and the warranty term in writing before work starts.
