I have a cedar shingle roof, and it is time to replace.
I am thinking that I don't want cedar anymore.
I am considering asphalt, and metal.
I plan to live in the house at least ten years.
Can I put the metal roof directly onto the purlins that the cedar roof
Does there need to be an underlay of some kind? There is an unheated
attic between the roof and the second floor of the house.
If I go with asphalt, do I need to place a plywood underlay?
Thank you in advance,
