CHIMNEY FLASHING REPAIR IN DORCHESTER, MA
Leaks around your chimney often start at the flashing. Proper repair stops water damage to your roof, ceiling, and walls.
What Is Chimney Flashing?
Chimney flashing is the metal (usually aluminum, copper, or galvanized steel) that seals the joint between your chimney and roof. It's designed to direct water away from this vulnerable intersection where the chimney penetrates the roofline.
Proper flashing consists of two parts: step flashing (L-shaped pieces that weave into the shingles) and counter flashing (metal embedded in the chimney mortar that overlaps the step flashing). When installed correctly, this system creates a watertight seal.
Signs of Flashing Problems
Flashing Repair vs. Replacement
Repair: If flashing is in good condition but has minor issues like failed caulk or small gaps, we can often repair it by resealing joints and securing loose sections.
Replacement: If flashing is rusted, corroded, improperly installed, or severely damaged, full replacement is the best solution. We install new step and counter flashing properly integrated with your roofing system.
Many "roof leaks" around chimneys are actually flashing failures. Before paying for expensive roof repairs, have your chimney flashing inspected by a professional.
