How do i use a roofing square.

Hold a torpedo level flat against the lip of the fence and adjust the height of the square until the bubble inside the level is centered. Read the pitch on the side of the rafter square. Hold your level outward perfectly horizontal from your roof so the bubble is in the middle of the indicator glass. A square simply refers to a 10 x 10 square of roofing.

Then place a torpedo level on the fat base of the rafter square and adjust the square until the level is level. With a torpedo level and a speed square you can pretty accurately gauge the pitch of any roof with a gable end photo 1. Then using a tape measure determine how many inches are between the middle of your level and your roof. A square roof is one in which all the corners are constructed at 90 angles.

Use the second row of numbers on the roofing square to determine the length of the hip or valley rafters. When covering the roof with plywood or metal sheets it s necessary to fit the materials to the rafters exactly. Bring a two foot level. For instance if the roof is 1550 square feet then it is 16 squares.

Locate the desired angle on the hypotenuse side of the square and pivot the tool until that angle s notch lines up with the top edge. To find the squares divide the overall roof area by 100 and then round up. This is simply 100 square feet of roof. When framing a roof whether metal shingled or shaked it must be square.

Step 3 template. The answer is the number of roofing squares for the roof. Climb to the peak of your roof. You can use the rafter to mark off your plumb cut where the rafter butts the ridgeboard the bird s mouth the angled cut where the rafter bites into the wall and the tail cut the rafter s.

You can then see the cut of the roof and also the cuts which need to be made to the piece of wood. Place the pivot point against the shingles. Squaring metal roofs is relatively easy and required for proper installation. Determine roof pitch fast using a carpenter square and torpedo level.

Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100. If the inch line is 8 the number below it is 47 65 cm 18 76 inches. Place the square with its fence on the top edge of the lumber. Multiply it by the total run of the common rafter.
