Chimney leaks from crown cracks and flashing failure
Why it happens here
North Franklin winters drive water into small cracks, then freeze and expand them. Crowns and flashing take the brunt of it. By the time you see a ceiling stain, the damage has been building for months.
Our approach
We diagnose with a camera and water test, then fix the actual source. New crown, new flashing, and water repellent on the stack. We do not just seal the stain and hope.
