I know you guys have used trusses before so question is, what's the proper
way to get the length? What I'm meaning to say is, are the overhangs
included in the measurement? Outside wall to outside wall is 20 feet. Would
I order a 20 foot truss or would it be a 22 foot truss. The extra 2 feet is
a foot overhang on each side. Snow and ice has recently collapsed my dads
garage roof. I've never used trusses before. Thanks.
