Chimney Flashing For Your Roof
If your roof has a chimney, it also has one of the most common leak points on the entire system.
Chimney flashing is designed to seal the area where your roof meets the chimney. When done correctly, it keeps water out for decades. When done wrong or reused, it is often the first place a roof will fail.
At Mr. GoodRoof, chimney flashing is treated as a critical part of the roofing system, not a detail to overlook.

What Is Chimney Flashing?
Chimney flashing is a combination of metal components installed around the base of the chimney to prevent water from entering the home.
Because a chimney interrupts the surface of the roof, shingles alone cannot seal this area. Flashing is required to bridge the gap and direct water safely away.
A proper chimney flashing system typically includes:
Each piece works together to create a watertight seal.
Why Chimney Flashing Matters
The area around a chimney is constantly exposed to water.
Rain flows down the roof and hits the vertical surface of the chimney, creating a high-risk zone for leaks. Without proper flashing, water can easily work its way behind the roofing system and into your home.
Chimney flashing helps:
This is one of the most important areas to get right.
The Problem with Reusing Old Flashing
One of the most common shortcuts in roofing is reusing existing chimney flashing.
This is often done to reduce cost, but it creates a major risk.
Old flashing may be:
Reusing these materials can lead to leaks, even if the rest of the roof is brand new.
At Mr. GoodRoof, we replace chimney flashing as part of the system to ensure long-term protection.
Custom-Fit for a Proper Seal
Chimney flashing is not a one-size-fits-all component.
Each chimney requires custom fitting to ensure the flashing properly conforms to both the roof and the chimney structure.
This includes precise cutting, bending, and layering of materials so water is directed away instead of allowed to penetrate.
Taking the time to do this correctly is what prevents future problems.
What Is a Cricket and When Is It Needed?
On larger chimneys, especially those located on the slope of the roof, a cricket may be installed behind the chimney.
A cricket is a small, peaked structure that diverts water around the chimney instead of allowing it to pool behind it.
Without a cricket, water can collect on the uphill side of the chimney and increase the risk of leaks.
