I am building a barn/workshop. I have read that metal roofs are much lighter that other roofing products like asphalt shingles. Can I therefore get away with spacing my rafters (or trusses) further apart and/or using lighter stock for rafters? --Thanks, Ron

Most metal roofs weigh around 1 lb per sq ft where asphalt shingles weigh 2.5 and concrete tile 10 lbs. The building code design loads for you area drive the live and dead loas and possibly saving 2 lbs/sf would make minimal differance especially when you need to increase the sheathing thickness or strapping size as you stretch out the rafters to accomodate the load. Remember the building code is a minimum code and you need to build a building to last. Certain metal roofs can be installed on strapping alone with an underlayment if the plywood is not required to brace your trusses. Ask your suppliers and building official more questions and then calculate the costs and any savings. Good Luck.
