Training Video #10 - Chimney Cricket
Posted by Ray Gessener
A chimney cricket is a roofing component required by IRC code 903.2.2 for all chimneys over 30 inches (you can often estimate this to be anything over four bricks).
This is essentially just an extension of your roof that runs perpendicular to your main roof between your chimney and the main roof.
It covers the width of your chimney and usually follows the same pitch as the rest of your roof.
