Enter the angle of the bay. Bay Angle is the angle that the side walls of the bay slant out from the wall the bay is built against. Select 30, 45, 60 or 90 degrees from the dropdown list or enter any positive number of degrees from 1 to 90 directly in the input field. Note: Partial hip roofs are common over porches, entryways, etc.
Easy Rafters is designed to calculate shed roofs that are framed to a ledger board nailed against a vertical wall, not freestanding shed roofs supported by walls at both ends. It is possible to calculate a birdsmouth near the top of the rafter for a freestanding shed roof by checking the kneewall checkbox and entering a setback for the kneewall ...
Bay Hip Rafter Run Offset = Common Rafter Run ÷ tan ( BHRR Bisect Angle) Projection Offset = (Back Wall - Face Wall) /2. Wall Hip Rafter Run = Projection Offset + Bay Hip Rafter Run Offset . Wall Hip Rafter Angle = arctan ( Common Rafter Rise ÷ Wall Hip Rafter Run) Wall Hip Rafter Length = Wall Hip Rafter Run ÷ cos ( Wall Hip Rafter Angle ...
This bay window rafter script will print out a chart of all rafter lengths and angles for the baywindow. The starting pitch is 3/12 and the ending pitch is 16/12. Auto Generated Rafter Tables for Equal Pitch Bay Window Roof with 45 wall angles. 45 wall with projection = 24''. 45 wall with projection = 28''.
Finally, press the “pitch” button, and the result is the top angle. Round it up, for 43°. Subtract it from 90 for 47°—which is the bottom angle. Because we’re at angle, I have to set the bevel cut for the top at 22½°. This fits perfectly from point to point, so I’ll take it and use it as a template for the other side.
