I am having a roofing job done --strictly standard asphault type dimensional
shingles on steep roof to an on roof copper spouting
I notice the other night as I had paid for a water and ice shield that I did
not see any type of adhesive backed rubber membrane at all but just a layer
of roof asphault shingle type material under the first layer of roof ing
Is this perhaps supposed to be some type of rain and ice dam type material I
have never heard of or have I been fleeced?
I had expected an adhesive backed rubber membrane from my on roof spouting
up under my roof that I am having done
or is there a new type of ice and water damn as this material I saw
resembles only half sheets of oridinary roofing shingles
for a reply
It was possibly just the starter course of shingles. When using 3 tab
shingles you install one shingle upside down or with the tabs cut off first
to provide protection for the gap between the tabs. I'm not sure if
architectural shingles have this same requirement or not.
