Chimney Repair in Decatur, Alabama

Chimney flashing, caps, crowns, and mortar joints are among the most common sources of roof leaks — and in Decatur, where the Tennessee River adds extra wind and moisture exposure on top of the usual wear on historic and newer homes alike, chimney leaks show up early and often. 1 Stop Roofing & Exteriors has repaired chimney leaks across Decatur and Morgan County for 45 years.

Decatur's riverside location and mix of historic and newer construction wear chimney flashing and masonry differently, but neither side is exempt:

Historic-district homes. Original flashing and mortar joints on older chimneys are frequently decades past the service life of the sealants and metal used when they were built. Mortar naturally erodes with freeze-thaw cycles, and river-adjacent humidity accelerates the process — flashing that was never replaced during a re-roof is a common hidden leak source.

Newer subdivisions on the city's edges. Builder-grade flashing and caps are common on newer-construction chimneys, and the transition point between chimney masonry and architectural shingles is exactly where installation shortcuts show up first — often well before most homeowners expect a chimney issue.

River wind and moisture make both worse. Decatur's Tennessee River location means higher wind and moisture exposure than inland areas, and that exposure finds weak flashing and mortar fast. If a storm just came through, a chimney leak that was slow and hidden can suddenly become an active drip — see our Decatur storm damage page if that's what brought you here.

• Chimney Flashing — step flashing, counter flashing, and apron flashing installation and replacement. The most critical waterproofing component where your chimney meets the roof.
• Chimney Caps — stainless steel and copper caps to prevent rain, debris, and animals from entering your flue while improving draft performance.
• Crown Repair — cracked or deteriorating chimney crowns allow water to seep into masonry and your home's interior. We repair and seal crowns for lasting protection.
• Mortar Joint Repair — tuck-pointing and repointing deteriorated mortar joints to restore structural integrity and prevent water infiltration through the chimney stack.
• Waterproofing — breathable waterproof sealants applied to chimney masonry to prevent moisture absorption while allowing trapped moisture to escape.
• Cricket Installation — chimney crickets (saddles) divert water and debris away from the uphill side of your chimney, preventing pooling and leaks on wider chimneys.
