How to attach the shed roof to the walls.

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. Add a second top plate to more securely attach the walls and to add strength and support for the roof. Rafters are installed piece by piece during the construction of the roof. Attach roofing to the garage wall with bent metal flashing that goes up the wall and over the roof.

Fasten the truss by driving 8d finishing nails at an angle down through the board just above the birdsmouth notch and into the underlying wall plate. You have to do it thoroughly so that the rafters sit flush on it. Attach the end rafters to the wall plates of your shed frame. Do the same with the rest of the pieces.

But you have to do it before you build the walls. Use 3 nails for each side. After the roof is sheeted then go around and re level the floor. Make a cutting on one of the sides of the horizontal roof beam on an angle.

Cover the walls with board and batten 4 by 8 foot sheets of plywood nailed vertically to the sheathing strips with the seams covered by 1 by 4 inch batten boards. This will occur at all four corners adding an additional attachment point for each corner. After that to make it flush with the roof of the existing house cut the two outer rafters. Experiment with jacking different corners or walls until you get the results you want.

The best method is to snap chalk lines on the shed floor to outline the truss parts. The top plate on each side will overlap and attach to one adjoining wall corner. The porch roof may match the pitch of your home or have a more shallow roof pitch. Rafters are beams that run from the peak of the roof to the top plate of the supporting walls.

Seal the top with clear caulk. If you re building your own roof trusses the handiest place to assemble them is right on the shed floor. The positioning of your rafters will depend on the pitch of the porch roof. Joist hangers can help you mount each rafter to the house.

They join at the peak of the roof by connecting to the opposing rafter or to a ridge beam that runs the length of the peak of the house or shed. Put a jack under a corner and raise it up till the roof sheeting comes in line with the truss. Then nail that piece down. Then use the chalk lines as a guide for cutting the truss patterns and assembling the trusses.
