Chimney Crickets

A custom-built cricket behind your chimney that diverts water around it and prevents pooling, leaks and rot.

Water loves to collect on the uphill side of a chimney, and over time that standing water finds its way in. Our team builds a chimney cricket - a small peaked ridge behind the chimney - to properly divert water around it and prevent accumulation and damage from above.

Framed, decked and flashed to match your roof, a cricket protects one of the most leak-prone spots on any roof. If your chimney is wide or sits low on the slope, it is well worth doing.

Common chimney crickets questions

What is a chimney cricket and do I need one?

A cricket is a small peaked diverter built on the uphill side of a chimney that splits water and snow around it instead of letting it pile against the brick. Building code requires one on chimneys wider than 30 inches, and most chimney leaks we see on wide chimneys without crickets are exactly this problem.

My chimney leaks — is the cricket the fix?

It is one of three usual suspects, alongside failed flashing and the chimney crown itself. We inspect all three before quoting, because building a cricket will not stop water coming through a cracked crown. You get a diagnosis with photos, then the right repair.

Can a cricket be added to an existing roof?

Yes. We frame the cricket, sheath it, flash it into the chimney with step and counterflashing, and shingle or metal-clad it to shed cleanly into the adjacent roof planes. It is a one-day job on most homes and permanently solves the snow-and-debris pile-up behind wide chimneys.
