Woodbury homes built in the 1980s and 1990s around Tannerwood Park and Central Woodbury often use step flashing integrated with asphalt shingles against brick chimneys. Cold winters cause repeated expansion and contraction that cracks sealant and lifts metal edges, allowing meltwater to enter attics above living spaces. We replace corroded sections with 26-gauge galvanized or copper flashing cut to match existing profiles rather than relying on caulk patches that fail within two seasons.
Washington County building practices require flashing to extend at least 6 inches up the chimney and 4 inches under shingles. In humid summers, trapped moisture under improper overlaps leads to deck rot that spreads toward Woodbury Village homes with vaulted ceilings. Technicians check for ice dam damage near valleys and ensure counterflashing is reglet-secured into mortar joints instead of surface-mounted, which pulls away during heavy spring rains common between St. Paul and Cottage Grove.
Edge cases include chimneys with stucco parging that hides previous flashing failures and homes near Tannerwood where mature trees drop debris that holds water against the flashing line. We remove and reinstall adjacent shingles carefully to avoid disturbing ridge vents, then test with a hose after completion to confirm no water reaches interior sheathing.
Homeowners sometimes confuse chimney flashing issues with ridge vent leaks, but the water stains typically appear first on the north side of the chimney chase where snow lingers longest in Woodbury winters.
Technician insight
In Woodbury the thing that catches most people out with Chimney Flashing Repair is assuming surface caulk will hold through another freeze-thaw winter on 30-year-old homes in Central Woodbury where the original step flashing has already lifted.
Tannerwood Park Chimney Leak
Water stains appeared on a second-floor ceiling after March melt. We found lifted step flashing on the north side where snow had sat against the chimney. New copper flashing was installed with proper overlaps and the deck was checked for rot before shingles were replaced.
