How To Attach The Shed Roof To The Walls

Joist hangers can help you mount each rafter to the house.

How to attach the shed roof to the walls.

This will occur at all four corners adding an additional attachment point for each corner. Use screws to secure the rafter to the sill plate. The best method is to snap chalk lines on the shed floor to outline the truss parts. 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.

Experiment with jacking different corners or walls until you get the results you want. Attach roofing to the garage wall with bent metal flashing that goes up the wall and over the roof. Put a jack under a corner and raise it up till the roof sheeting comes in line with the truss. Lower the first rafter truss into place at either the front or back of the shed.

Rafters are beams that run from the peak of the roof to the top plate of the supporting walls. If you re building your own roof trusses the handiest place to assemble them is right on the shed floor. The top plate on each side will overlap and attach to one adjoining wall corner. Attach the horizontal beam by using a nail gun.

Then use the chalk lines as a guide for cutting the truss patterns and assembling the trusses. But you have to do it before you build the walls. After that to make it flush with the roof of the existing house cut the two outer rafters. After the roof is sheeted then go around and re level the floor.

If you decide on a shallow pitch porch roof use 2 by 6 foot rafters. The positioning of your rafters will depend on the pitch of the porch roof. 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. Then nail that piece down.

Attach the end rafters to the wall plates of your shed frame. 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. Add a second top plate to more securely attach the walls and to add strength and support for the roof. Make a cutting on one of the sides of the horizontal roof beam on an angle.

Use 3 nails for each side. Do the same with the rest of the pieces. Rafters are installed piece by piece during the construction of the roof. 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.
