Looking at building a 20x20 garage and I'm considering metal roofing. Not overly popular up here but getting more so. Any thoughts on using this vs asphalt/fibreglass shingles? I am a decent roofer and could lay shingles myself so no labour cost. Same with metal roofing I would install it myself after learning installation technques.
How much prep is needed? Specifically 1/2" plywood sheating needed or just strap it off? That would affect cost big time. Also salt belt up here and constant salt in air from ocean and road salt...corrosion problem?
Not much help here from building supply companies as they contract it all out. Got my first quote from metal roof suppler and it ain't cheap...
Any thoughts appreciated.
