Does anyone know the best way to tie into an overhanging eve when building a window bay? The rafters overhang 24 inches and the bay will protrude 16 inches from the existing wall. Also I plan on putting a header in where I cut out the wall but wonder if one is neccesary above the actual window itself. Hope somebody has encountered this situation before and can offer some advice. Thanks, Chip:)
You indicate that there is a 2-foot soffit overhang over the bay window. This strongly suggests the wall is a support wall for the rafters above and a header is required. The size depends on local factors (snow load, code), window span and your roof structure. I recommend you consult a builder or engineer on the header size. The window can be tied into the soffit with 1x trim boards to join and smaller trim over the seams. Still, the structure is the more important issue here.
