This is my first cricket attempt on a chimney. Wondering how wide you guys build your crickets. do you go full width of the chimney or less? Also, what do you cover the cricket with? It is an asphalt shingle roof. I am going to cover with water and ice and then rubber roofing. Thanks.

In most cases, I will use a 4' level to get my ridge height at the chimney, then make my rafters long enough to get the valley to finish just a bit beyond the finished surface of the chimney. They get I&W first, then typically asphalt shingles. In some cases, they will get a soldered seam copper pan.
You may be able to make out this one to get an idea.

Usually the crickets I deal with are covered with the same material as the rest of the roof. Around here that means it is asphalt shingles with few exceptions.

The cricket is always as wide as the chimney to prevent having a catch area behind the chimney, which is the purpose of a cricket in the first place. :thumbsup:

Ok. No problem going full width. It is only 24" wide anyway. Do you guys seal all your shingle nails on the cricket or just roof it normally? Also, I figured I would try to match the existing pitch of the roof depending on how my shingle courses ended up.

Crickets are the simplest thing that I see most guy's strugle with.
I just mark a level line from the roof to the center of the chminey, measure the legnth of the ridge, (level line) and from the center mark to the bottom corner of the chim.
Cut 2 triangles from 3/4 ply, hold them together flat and nail the ridge from both sides. Pull the bottom corners apart, drop it on the roof, beat to fit and nail it to the roof ply. Keep it small enough and you can jump all over it with no deflection.
Cover it with I+W then cover with whatever roofing you have on the rest of the roof. A good cricket shouldnt be seen from the ground.

Just did it yesterday...on a 12/12....36" chimney.

I cut two 2x4's 24" long with 45* seat cut. Held them 1/2" back from the side of the chimney, let them cross and then I scribed them to mark my plumb cuts.

Cut my pieces then nailed the triangle together. Marked center, n tapconned to brick. Leveled back to the roof for ridge length...18" so no rafters were needed.

then measured one side for the ply. cut ply and used that piece to scribe the next piece. assembled, I&W. Then shingled like I would normally, just on a smaller scale.

When I was using one, it was called The Reason.

As I would swing, I would chant, "Because I said so, Damnit!"
