Which are the better shingles?
I have had a few roofing bids come in and they are pretty close to each other(the lowest uses IKO shingles which I have done some research on and would not ever consider). They are Certainteed XT 25 yr, Certainteed Landmark 30 yr and Elk Prestique 30 yr. Which is the better shingle?
Also, one roofer said he would use a 36" ice shield. He said it is code(we have none now). Others use 72". Is it really of any benefit to use a 72" shield?
