Getting bids for residential flat roof replacement in Seattle
IB products are the top three $$$
Search on this forum and others mention versico as an “over the counter” or “retail” choice (???)
I see lots of posts touting the long term durability of IB, but is the cost difference something other than this durability factor?
Mention of IB only using certified installers?
Or is it the lifetime warranty?
Bids all have similar other features for underlayment and fastening
thanks in advance
