Chimney Flashing Repair
Stopping leaks where the chimney meets the roof.
One of the most common sources of chimney leaks isn’t the chimney itself—it’s the flashing, the sheet metal installed where the chimney meets the roof. Flashing is designed to create a watertight seal at this vulnerable joint, directing water away so it doesn’t seep into your attic, framing, or ceilings.
When flashing is rusted, cracked, poorly sealed, or missing altogether, it allows water to enter your home. Over time, this leads to wood rot, mold growth, stained ceilings, and costly structural damage.
At Northwest Chimney, we specialize in chimney flashing repair and replacement, ensuring your system is properly sealed and protected against water intrusion.
Flashing Replacement
For flashing that is rusted, missing, or improperly installed, we provide full flashing replacement.
This involves carefully removing the damaged materials and installing new step flashing and counter flashing, properly integrated with your roofing system.
We use high-quality materials—aluminum, stainless steel, or copper—depending on your chimney and roof design. Unlike quick fixes that rely on caulk or tar, this method creates a layered, durable barrier that protects your home for decades.
FlashSeal Application
A cost-effective way to seal flashing leaks without full replacement.
When chimney flashing is still structurally intact but leaking at seams or joints, FlashSeal provides a professional-grade solution. This elastomeric coating, developed by SaverSystems, is applied directly over the flashing to seal cracks, gaps, and separation points.
Once cured, FlashSeal forms a flexible, waterproof membrane that expands and contracts with your home’s natural movement, keeping water out season after season. For many homeowners, FlashSeal is a cost-effective repair option that extends the life of existing flashing while stopping leaks at the source.
Why Flashing Repairs Matter
Flashing failure is one of the most common causes of chimney leaks. Small gaps may look harmless but can allow gallons of water into your home over time, causing thousands of dollars in hidden damage. Professional flashing installation ensures your chimney and roofline are protected against water intrusion for years to come.
