More specifically it is a beam that goes from the peak of your roof down to the eve.
Framing shed roof rafters.
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 then have rafters running down from this ridge board and resting on the top wall plates.
Difference between a rafter and truss.
A rafter is the frame of your roof.
The roof rafters provide integral structural support to the roof.
Lower the first rafter truss into place at either the front or back of the shed.
Before you cut your boards you ll need to measure the width of your building and calculate the exact length of each rafter.
If you re framing a gable roof on a new house or building a shed or even a doghouse with a gable roof you ll need to cut a number of roof rafters.
If you plan to have eaves to protect the shed walls make sure you add the extra length when measuring the rafters.
If your project had a rafter length of 8 or less a safe and strong method is to use 2x8 framed 16 on center.
Use 3 nails for each side.
Install the gussets on both sides of all the rafters except for the gable end rafters.
Place a nail every three inches along the edges of the gusset.
Now build the remaining roof rafters using the original rafter template and the jig on the shed floor.
Sometimes the rafter will have a tail and extend out past the wall so that you have a soffit or overhang.
Test the rafter assembly by standing it up and lining it up with the edges of the shed floor.
A stick framed roof uses 2x4 s or 2x6 s or whatever you are framing with but has a ridge board running down the middle ridge line.
Attach the end rafters to the wall plates of your shed frame.
