So we bought a house that needs everything. Including a roof.
It is a contemporary, with a tongue and groove 2 inch thick roof system. It currently has an inch of foam insulation. Not in Mass, that won’t do.
So I we are going to do a roof. Obviously Asphalt is the most cost effective on day one. The other advantage is DIY repairs, I mean if a branch dings the roof, I would like to be able to throw a few shingles up to fix it rather than be looking at serious cash.
That said, there seem to be some interesting products out there in the metal roof market.
So, first question:
Pricewise, asphalt is so reasonable, that what is the best shingle for an install over foam? We plan on putting about 3 inches with some CDX. I was planning on putting sleepers for an airspace, but if they will warranty it with no venting, why not So, what is the consensus ‘best’ for this application ?
If I were to go metal , I have to think about whether standing seam is the look I want. If a metal shingle product, what is the most cost effective?
Frankly, I hate buying something that is single source, that might not exist by the time I need some maintenance, or god forbid I want to change something and need to get a small amount of the product to add something or add in a skylight etc.
Anyway, I have a few months to make a decision so am looking for advise.
