Hello, I’m wondering if someone can tell me if a home inspector should know attic rafter spans. We have a stick built attic with 2 x 6 attic rafters which hold up the roof. Every contractor tells us the rafters need to be 2 x 8 to carry the load of the roof. Even the center ridge beam is 2 x 6.
In addition the floor plan below ie: the ceiling of the rooms is an open floor plan with rooms as big as 16 feet. We are being told by contractors that the beams which hold up the ceiling needs to be at least 2 x 8 because the span underneath is 16 feet.
Should a home inspector who walked the attic know to look for span issues?
Thank you for your help.
