I'm getting quotes for a new roof. One contractor has proposed a system which I never heard of. The proposal consists of tearing off roof covering down to sheathing. Then, they propose to put ice guard on all seams of the plywood 6" wide, and seal the deck with deck sealant. They won't be using any felt and just install the shingles over this. They suggest there is no way ice or water will penetrate the decking if I get ice dams. To do this, the cost is $1 per sq. ft. of decking, I have 24 sq. or 2,400 sq. ft. to cover. So the price is $2,400 to use this method. My question is: Is this a reasonable cost?
