CHIMNEY FLASHING AND CRICKETS
Chimney flashing and cricket repair protects the area where your chimney meets the roof. Proper sealing helps prevent water leaks, moisture damage, and structural issues caused by improper drainage.
HOW WE SEAL CHIMNEYS AGAINST WATER INTRUSION
We seal chimneys using a combination of proper flashing, waterproofing materials, and targeted sealing techniques to help prevent water from entering vulnerable areas of the system. This process protects both the chimney structure and surrounding roofing components from long-term moisture damage, including leaks, deterioration, and internal rot.
SIGNS TO LOOK FOR:
Ceiling leaks near chimney
Water stains on walls
Roof moisture around chimney
Visible gaps in flashing
WHAT WE REPAIR:
Damaged flashing
Improper roof sealing
Cricket installation/rebuild
Leak correction around chimney base
WHAT IS CHIMNEY FLASHING
Chimney flashing is a critical waterproof barrier installed where the chimney meets the roof, designed to seal gaps and prevent water, snow, and debris from entering the home. When properly installed, it directs water away from the chimney and into the roof drainage system, helping protect against leaks, rot, and mold damage over time.
Most chimney flashing systems have a long service life when maintained properly, but failure or improper installation can lead to significant water intrusion issues.
For chimneys wider than 30 inches, a cricket (saddle) is recommended to help divert water and debris around the chimney. This prevents pooling behind the structure, reduces long-term stress on the flashing, and helps extend the overall lifespan of the roof system.
POST-ROOF REPLACEMENT CHIMNEY INSPECTION
If you have recently had your roof replaced, it is a good idea to have your chimney inspected to ensure all related components were properly reinstalled and sealed. Improper flashing installation is one of the most common issues we find after roofing work, and it can allow water to enter the attic or surrounding structure if not corrected.

WHAT ARE CHIMNEY CRICKETS?
A chimney cricket is a raised, pyramid-shaped structure installed on the high side of a chimney where it meets the roof. Its purpose is to divert water and debris around the chimney, allowing proper drainage on either side instead of allowing buildup behind the structure.
Chimney crickets are typically recommended for chimneys wider than 30 inches. Without one, water can collect behind the chimney, leading to premature rusting of the flashing and increasing the risk of leaks, moisture intrusion, and long-term damage such as mold or wood rot within the home.
