Service · A1 Chimney & Roofing
A chimney cricket is a small peaked diverter built on the high side of a chimney. Roof water hits the peak and runs to either side instead of pooling against the brick.

The work
Crickets are for chimneys wide enough that water and debris sit at the uphill face. The cricket is framed, sheathed, and tied into the shingles with flashing. It is not a piece of metal leaned against the brick, and it is not a substitute for step flashing along the sides.
The joint itself, when the metal has failed, is flashing repair. A leak that is not at the chimney is roof leak repair.
Why it matters
Water that stands against the uphill face finds the flashing and the mortar. On a wide chimney that is the usual leak, even when the shingles nearby look new.
A cricket gives that water somewhere else to go. It is recommended when the chimney’s width calls for it, not on every pipe chase.
What to expect
The roof slope and the chimney width are checked, the cricket is explained, and the price is given before the roof is opened.
