My sister's uninsulated and unheated garage needs new shingles on the roof. Just about everyone I talk to says that these new "laminate" shingles are the only way to go. Not only are they less expensive than asphalt shingles, but they last longer as well. I'm wondering what people in here have to say about them. Also, I was told by one contractor here in Winnipeg that I don't need to tarpaper her roof before shingling because she has a 4:12 slope, which is supposedly steep enough to keep the wind from blowing water up under the shingles. However, a different contractor said that you need to install tar paper if you're installing laminate shingles. Does anyone know if this is true, and why? Finally, I think it's a good idea to install drip caps simply to protect the wood board that runs along the eve from rotting. But, I'm wondering if this can be done effectively without removing the evestrough? Would they simply notch the drip cap with tin snips wherever those long nails (called "ferrels") are and slip it behind the evestrough and then nail it down to the roof deck? Finally, it seems to me that the drip cap should go on first, under the tarpaper. Is this correct? Can anyone think of any reason NOT to go with laminate shingles? Everything I've heard people say about them is positive. In fact, one roofing company in Winnipeg I talked to says that they haven't installed any ashpalt shingles for over 2 1/2 years now. All they install is the laminate shingles. The guy told me that laminate shingles start at 30 year service life, but the price increases steeply if you want to go with 40, 45, 50 or "lifetime" laminate shingles. Well, my sister is 56 years old. I figure the 45 year shingles will do her until she's 101. But, realistically, I expect the 30 year shingles would actually last longer, say 35 years. That takes us to her 90th birthday, and by that time neither of us may even be around. So, I'm thinking of going with the least expensive 30 year laminate shingles. Anyone have any reason not to do that?
