This formula helps you to determine the length of the lanyard that you need to secure yourself on a roof without hitting the ground in the event of a fall. The sum of the elements above should be shorter than the fall clearance. If it’s longer, you’ll need to get a shorter safety ...
under a rafter to find the pitch. This is a special tool and can also be used to find level, plumb, or any angle in between.Another method is to use a level and framing square from on top of the roof. Place a framing square on the up hill side of the roof with the body level...
Directly below the 6 (inch) mark on the framing square read the required rafter length (13.42) per foot of run for a 6-inch rise (6 in 12) roof. To calculate the required rafter length multiply the total run length (half the building width plus the width that the roof is to overhang...
I have had to uncheck your reply as the correct solution because an unexpected problem showed up: the left rafter is being horizontally cut slightly above the plane of the other rafter horizontal cut, presumably because "fascia depth" is measured paralell to the roof, in this case with ...

While cutting the rafters use a rafter table, which comes in an instruction manual with the rafter square, to determine the length of the rafter. For a 5/12 rafter, that will be 13, or 13 inches of rafter for every foot of run; with a 12-foot run, that is 13 feet. Mark that sp...
The rafter angle or pitch. The length of the overhang. Depth of bird mouth. That is usually 1 1/2 inches so the rafter can rest at exactly the depth of the top plate. With this information determined and the rafter ends cut to the proper pitch, layout of the bird's mouth is fairly...

In order to build a roof over a deck, you will need to connect the new roof framing to the existing building. The most effective way...
Determine the building’s width and length and the rafter span in order to evaluate how many rafters are needed. Then determine the pitch. Divide the rafter’s span by two to find the rafter’s run. As an example, a building that’s 24 feet wide has a rafter run of 12. If your ri...
