What Causes Roof Leaks
Around Chimneys In Montgomery, TX?

Homeowners in Montgomery, Conroe, and The Woodlands call us about one leak more than almost any other: water showing up near a chimney. It might look like a ceiling stain or a soft spot on the wall, but the root problem usually starts where shingles meet brick or siding around that chimney.
Why Chimney Areas Leak So Often
Chimneys are a natural weak point in any roofing system. You have multiple materials meeting in a small area, and they all expand and contract at different rates in Texas heat and cold. Over time, that movement can open small gaps where water can sneak in even if the rest of the roof looks fine from the ground.
Flashing is supposed to protect this area, but problems start when:
- Step flashing and counter flashing were never installed correctly.
- Old flashing rusts, pulls loose, or is buried under too much sealant.
- Shingles at the chimney base crack, curl, or lose granules.
Once water gets behind the flashing, it can travel along the deck and show up several feet away inside your home.



Common Signs Of A Chimney Roof Leak
You do not have to climb on the roof to spot early warning signs inside your home. Watch for:
- Brown or yellow stains on the ceiling near the chimney.
- Peeling paint or bubbling drywall along the chimney wall.
- Musty smells in the attic after storms.
- Damp or darkened framing around the chimney when viewed from the attic.
Outside, look for cracked mortar, damaged chimney caps, or visible gaps where the chimney meets the shingles.
How We Fix Chimney Leaks The Right Way
At Handnail Roofing, we do more than smear new caulk and hope for the best. A proper chimney leak repair may include:
- Removing affected shingles around the chimney.
- Inspecting and replacing step flashing and counter flashing as needed.
- Checking the cricket or saddle behind larger chimneys and rebuilding it if water is pooling.
- Installing proper underlayment and leak barrier around the base of the chimney.
Because we hand‑nail our shingles, we can control every fastener around this sensitive area and avoid overdriven nails that can create more leak paths.
When To Call A Roofer In Montgomery County
If you see fresh stains after a storm, or you know your roof is 15+ years old and has a masonry or framed chimney, it is time for a roof inspection. Catching chimney leaks early is almost always cheaper than repairing rotten framing, insulation, and interior finishes later.
We inspect roofs throughout Montgomery County, including Montgomery, Conroe, The Woodlands, Magnolia, Tomball, Cypress, and Spring. If you are worried about a chimney leak, we will walk the roof, document what we find, and give you straight answers about repair or replacement options.
