How to install roof rafters.

Attach the first rafter. Depending on the shape of the roof the amount and the shape of the sheathing will vary. Install the gussets on both sides of all the rafters except for the gable end rafters. Or join the members using manufactured metal splice plates.

Next set the framing square on top of the rafter beam and use a pencil to trace the outside edge of the framing square s tongue. To cut roof rafters start by fixing the stair gauges on your framing square to the dimensions of your pitch. After you ve braced and installed all the rafters you re ready to start installing a layer of roof sheathing basically just plywood over which the weather stripping and shingles will be installed nailing it to the outside of the rafters accordingly. The holder will keep the rafter in position now.

Lay one end of the rafter over the outside wall frame and as you climb the ladder carry the other end of the rafter pre cut to conform to the angle of the roof or pull it up by using a rope and then set the rafter into the slot in the holder. Now build the remaining roof rafters using the original rafter template and the jig on the shed floor. Once you ve marked the lines use your pencil to draw the diagonal length on the rafter. To do this butt the ends of the rafters together over a supporting beam.

Then nail two pieces of 1 by or 2 by lumber of the same width as the rafters as show at left and about 18 inches long centered over both sides of the splice. Install the roof sheathing.
