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...

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...
How to Cut Rafters with a Rafter Angle Square 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 ...
Remove any piles of wood or tree branches that are near your tree to eliminate shelter. Figure out where the rats are sheltering so you can successfully trap the rats. Rats found in trees are often known as roof rats, as they may jump from a roof into the tree. ...
blueprints, so to speak. Nearly every general contractor and construction professional sees them at some point during the building process. They’re even useful if you’re tearing something down: Demolition experts use blueprints to figure out which areas need to be blasted tobring a building ...
There will be 12 altogether, six each side of the roof. Fix the rafters to the beam. The placement of the rafters is shown in the plans (‘looking down view’ on page four). Note that there is a double rafter at each end of the roof. This is so the inside top of both front ...
Step 5. The roof On a flat surface, make up the two roof frames by first screwing the rafters(c)together at the apex, then screwing the collar ties(d)to the rafters(c). Then nail the wedges(i)to the bottom topside of each rafter. Seefig 1below. ...
any protrusions in your roof for lavatory vent stacks, chimneys, etc you will have to cut holes in the roofing felt for them as well as do any needed flashing. I'll let you figure that out, because you should have planned a hole-free roof. Repeat the process on the other side of ...
