Framing and roof crickets.

Install a waterproof membrane over the cricket sides and edges fastened to the cricket with a construction stapler. You will need to use compound miter cuts for the cricket rafters. This also makes it easier. Select build roof build roof from the menu and in the build roof dialog specify the pitch framing and any other attributes that you will need for the cricket.

Do not check build roof planes. 2x8 sleepers should be nailed to the roof surface to pick up the ends of the rafters. Ok so a four foot wide chimney has a span of 4 foot and half of that is the run which is 2 foot. This beam will provide the backbone for the cricket or saddle.

In this example a pitch of 12 12 and 1 1 2 x 5 1 2 rafters are specified. The cricket or saddle basically rests on top of the house roof to visually extend the porch roof gracefully into the house roof. Secure the plywood triangles to the roof decking and cricket ridge with galvanized screws.
