Measure the inside dimension of the beam and subtract ⅛ inch to determine the size of the mounting blocks. Cut the appropriate number of mounting blocks determined in Step 1. Dry fit each of the blocks to ensure that they don't have to be forced onto the beam. Too tight a fit could damage the beam.

40ft x 12″ = 480″ (length in inches) ÷ 24″ on-center = 20 rafters. After getting the answer, add 1 for the ‘0’ rafter and multiply it by 2. You’ll get the number of rafters needed for your roof. 40ft x 12” = 480” ÷ 24” on-center = 20 rafters + 1 = 21 rafters per side x 2 = 42 rafters. Get a Free Roofing Estimate.
