Hi.

Does anyone know what size lumber should be used for roof rafters? We checked the rafters on the part of my house that has the flat roof and the rafters where they meet the wall joists are only about 1 1/2 inches wide!! I thought that 2x10's would have been used , but it looks like the rafters were trimed down to that size to fit in the narrow space in the roof. the roof is 20' x 34'. There is only a couple of inches of space between the ceiling and the rafters. don't see any room for insulation. The flat roof is only 7 years old. One roof suggested changing the flat roof to a regular pitched /hip roof. Any suggestions? What really concerns me is the heavy snow load in the winter.

Thanks.

Bob
