All the shingle companies tried a new "better" way of making theirs and they got burned. That's why they curled after a few years. They are supposed to have corrected the problems and I think they have. The ones we have put on in the last 8 years look as good as the day we put them on. Certainteed was mentioned and they did have a lot of bad ones out there. Their new ones are much improved with a good warranty. I would recommend going with their Landmark series of laminated ones. $96 a sq. locally for just the shingles. Local codes will determine if you need the ice shield or not. With the energy efficient trusses used in newer homes now the ice build up isn't much of an issue but code still says you have to have it. If your selling in 10 yrs. that's a long time to try to be planning for what a new buyer wants. He may turn his nose up at the steel even thought it is better. Ask an insurance adjuster what he recommends for replacement brands. Around here they all say the Certanteed hold up the best. Here is a link to Certanteed's warranties.
