I am a homeowner and hired a GC to do some work on my house including installing 2 new skylights in the entryway. The idea was to get 2 - 22X46 skylights and place them in between the rafters so that we don’t need to structurally change the roof. As he requested curb mounted I got the Velux FCM 2246 along with the higher profile flashing (since I have a Spanish tile roof). My challenge is that he claims that he was not able to place the skylights close enough together so that it sits evenly between the rafters and thus it is offset about an inch over the other rafters (see arrows). He needed to add two supports (“B” and “C”) to the middle rafter (“F”) to create more space between the two skylights. Thus when he finishes with drywall, the drywall will have to hit the glass of the skylight and it I fear that it will not look clean. The curb he built (“A”) is not flush with the rafter (“D”).
Is this the correct way to do this? I was expecting the drywall to be flush with the curb built (“A”) and feel that it will look awkward touching the glass, plus I loose about an inch of glass.
See attached image for the above letter references. “D”, “E”, and “F” is existing rafters and joist.
