Where the chimney meets the roof is one of the most common places for a leak to start. Dee's Roofing repairs and replaces chimney flashing so water runs around it, not into your home.
A chimney interrupts the roof surface, and the only thing keeping water out of that gap is the flashing. Over time, sealant dries and cracks, metal rusts or pulls loose from the mortar joints, and leaves pile up on the uphill side, holding water against the joint. The result is often a stain on the ceiling or wall near the fireplace. Dee's Roofing provides chimney flashing repair and replacement for homes across Knoxville and East Tennessee.
Proper chimney flashing is a system: apron flashing across the front, step flashing woven into the shingles along the sides, counter flashing set into the mortar to cover it all, and a cricket or saddle behind wider chimneys to split the water flow. When any piece fails, water gets in.
We'll inspect the flashing and the decking around the chimney, repair or replace what's failing, and make sure the shingles tie in correctly. Your estimate is free, and the work is handled by a family-owned, licensed and insured local crew.
Each part of the flashing system has a job to do.
Individual pieces woven with the shingles up each side of the chimney.
Metal set into the mortar joints that overlaps and protects the step flashing.
Across the downhill face, directing water back onto the shingles.
A small peaked section behind wide chimneys that splits water flow.
Chimney leaks are often slow, so they go unnoticed for a long time. By the time a stain appears, the decking, framing and even the chimney chase around the fireplace may be wet.
Caulk and tar smeared over old flashing might stop a leak for a season, but it doesn't fix rusted metal or flashing that's pulled out of the mortar. A proper repair rebuilds the system so water is directed away from the gap.
We also check the decking around the chimney while we're there, since it's one of the most common spots for hidden rot.
Here's what a chimney flashing repair from Dee's includes.
Stains on the ceiling or walls near the chimney, water in the attic around the chimney, or visibly loose or rusted flashing are common signs.
Minor issues can sometimes be resealed, but rusted or loose flashing usually needs to be replaced to stop the leak for good. We'll tell you which makes sense.
A cricket is a small peaked structure on the uphill side of a wide chimney that diverts water around it instead of letting it pool behind the chimney.
Our work focuses on the flashing and the roof around the chimney. If we notice brick or mortar issues, we'll let you know so you can have them addressed.
Caulk can be a short-term fix, but it doesn't solve failed or rusted flashing. A proper repair rebuilds the flashing system.
