A bay roof is a three sided roof framed against a vertical wall of a building, usually covering a projection from the building such as a bay window or nook. A projection with four or more angled faces is a bow and cannot be calculated with Easy Rafters.
Framing a bay roof can be very frustrating, often times even an experienced roof framer will resort to "trial and error" cutting and fitting of the pieces required for a bay roof. Sure signs of this are fascia boards that aren't level or taper from one end to the other, soffits that vary in width, or unequal slopes for the three sides of the roof. Easy Rafters greatly simplifies this task by calculating the rafters needed to frame a bay roof with equal slopes for all sides, level fascias, and consistent soffits.
Once all the bay dimensions have been entered, the preview window will display a plan and elevation view of the bay roof that reflect the actual bay dimensions. Note that the front elevation is a view of the finished roof with overhangs and fascia boards while the top view does not include overhangs.
The bay roof drawing pages display dimensioned side views of the bay common, bay hip, bay ledger, and bay center ledger rafters. Bay hip and ledger drawings also include schematic top views to illustrate the location of the measuring lines and the types of bevel cuts required.
