Chimney Flashing Repair in Worcester, MA
If you have a stain on the ceiling near your chimney, failed flashing is one of the most likely causes. We replace flashing the right way — with proper step and counter flashing, not a smear of roof tar.
- Two-piece step + counter flashing systems
- Aluminum, copper, or galvanized options
- Worked into existing roof — no full reroof needed
- Stops chimney leaks at the roofline

Why Chimney Flashing Fails First
The chimney-to-roof joint moves constantly. The chimney expands and contracts in heat. The roof deck flexes under snow load. Ice dams push water uphill underneath the shingles. After 15–25 years, even quality flashing starts to lift, rust, or pull away — and water finds its way in. In Worcester, we also see a lot of homes where the original flashing was done as a single piece of metal sealed with roof tar. That setup has a maximum lifespan of about 10 years before the tar dries, cracks, and starts leaking.
How Proper Flashing Should Be Installed
Quality chimney flashing uses two interlocking layers. Step flashing is woven into each course of shingles along the side of the chimney. Counter flashing is cut into the mortar joints of the chimney itself and laps down over the step flashing. This two-piece system lets the chimney and roof move independently without breaking the seal. Done right, it lasts 30+ years — long enough to outlive most roofs.
Diagnosing the Real Source of a Chimney Leak
Not every chimney leak is flashing. Sometimes the crown is the real culprit, sometimes it's open mortar joints, sometimes it's a missing chimney cap. Before quoting a flashing repair we always confirm where the water is actually getting in — otherwise you pay for the wrong fix and the leak comes back. If you've already had flashing 'repaired' once and it's still leaking, that's a strong sign the original diagnosis was wrong. Get a second opinion.
