The most common cause is corrosion or separation of the flashing material due to our local weather cycles. In Wakefield, freeze-thaw conditions and exposure to moisture can cause the metal to deteriorate or the sealant to fail, creating gaps where water can seep in behind the chimney. A proper repair involves inspecting the step flashing and counterflashing, replacing any compromised sections, and applying a new, durable sealant to create a watertight barrier.

Signs of flashing corrosion include visible rust stains running down your roof or siding, granules collecting in gutters near roof valleys or walls, and water stains on interior ceilings or walls adjacent to chimneys, vents, or dormers. In Wakefield, it's wise to have a professional inspection after major storms or seasonally, as early corrosion might not be obvious from the ground. We can assess the integrity of the flashing and recommend targeted repairs before a small leak becomes a major issue.

Flashing is the critical seal at roof penetrations and transitions. A small leak from corroded or failed flashing can allow water to travel far from the source, damaging roof decking, insulation, attic structures, and interior walls. In our climate, this trapped moisture can also lead to mold and wood rot. Prompt repair by a local roofer like us prevents extensive, costly damage and helps maintain your home's structural integrity and energy efficiency through the New England seasons.
