What Is a Roof Cricket — and Why Your Roof Might Need One
When it comes to roofing, some of the most important features are the ones you rarely notice. A roof cricket is one of them — a small but critical structure that helps protect your home from leaks and water damage.
SO, WHAT EXACTLY IS A ROOF CRICKET?
A roof cricket (also called a saddle) is a small, peaked structure built on the high side of a chimney or other roof penetration. Its job is simple but vital: to divert water away from areas where it might otherwise collect or pool.

Without a cricket, rainwater can sit behind the chimney or low points in the roof, eventually seeping through shingles, flashing, and underlayment — leading to leaks, rot, and even structural damage.
WHY ROOF CRICKETS MATTER
Prevent water buildup behind chimneys and roof joints
Reduce leak risk by improving water flow
Extend roof life by keeping materials dry and protected
Improve drainage during heavy rainstorms
Enhance efficiency for larger chimneys or complex rooflines
In some areas, building codes require roof crickets on chimneys over a certain width — a detail many homeowners aren’t aware of.
DO YOU NEED A ROOF CRICKET?
If your chimney is 30 inches or wider, or if your roof has areas where water tends to collect, a cricket may be a smart (and sometimes necessary) addition. During your next roof inspection, ask your roofer to check whether your chimney flashing and drainage setup include proper crickets or diverters.
