How to seal a hip roof to a wall.

Sheet of housewrap or even better a piece of self adhering roof underlayment to the wall before the first truss or roof rafter is placed against it. The most common roof to wall intersections involve either a gable roof with its ridge running perpendicular to the wall or a shed roof that slopes downward away from the wall. Apply a generous bead of waterproof roof caulk to both edges of every 6 inch wide horizontal end lap seam with a caulking gun. Apply caulk to every screw head.

Ideally i like to start by installing a 3 ft. Next i ll remove the hip cap get our z trim cut them to length and install them. The porch roof may match the pitch of your home or have a more shallow roof pitch. In the same way that we use z trim for the installation of end wall flashing and sidewall transition we re going to do the exact same thing here on the hip.

Use screws to secure the rafter to the sill plate. The positioning of your rafters will depend on the pitch of the porch roof. If you decide on a shallow pitch porch roof use 2 by 6 foot rafters. Allow the caulk to dry completely.
