Given the total rafter length (measure from ridge to lower roof edge) and rafter run (half the building width plus the roof overhang past the building wall) we can figure the roof rise. If we know the roof run and rafter length, we find the roof slope by calculation or we use the fr...
The Rafter Angle Square also makes an excellent right angle guide for an electric saw to run against. Both the professional tradesman and the handyman will find the Rafter Angle Square convenient to use. All of the necessary instructions for basic roof construction are included in our ...

How did we figure that? We'll use the tangent function provided by geometry. The tangent of an angle of a roof slope can be calculated as rafter or roof rise divided by rafter or roof run or Tan (tangent) 38° = Y / X We could actually calculate the tangent value for an angle,...
Adding a bird's mouth to a roof raftershould be the last step in the completion of your rafter but is the most difficult to get right. This cut allows the rafter to sit squarely on the top plate and when cut right gives a solid foundation for attaching the rafter to the wall. Step...
of the completed building as if it were sliced in half vertically. It helps the viewer understand the relation between floor heights, rafter lengths, stairway designs, and other structural elements. Note how, in the example, the stairs appear as they would from the side, similar to a ...
Purchase a glue board rat trap and place it in the areas where you’ve seen the rats. Make sure to get a glue board that will stick to a thick tree branch, roof or rafter. Purchase commercial snapping rat traps specifically made for roof and tree rats. Bait the traps with whole nuts...
How to Build a Treehouse: This particular design requires two or three trees (or branches) in close proximity. It was made over the course of several weekends using new, pressure-treated wood for the support structure and floor and an old fence was recyc
Next you will find the "building and installing rafters" video. The pitch or slope of the roof in this project was 6/12 and I get right into figuring out the rafter angles and lengths here and show you the math on how to get it all figured out....
