Building a cricket involves more than slapping up a small roof. The structure must match your existing roof pitch to ensure water flows correctly.

Flashing integration proves critical for cricket success. The cricket must tie into existing step flashing along the chimney sides and counter flashing into the chimney mortar joints.
