I'm not sure if I'd recommend them to a friend yet because we got the roof put on in November and last week, they had to come out because we had water running into the kitchen. They came out and redid a couple of things, but I don't know if it'll hold up or not yet.
Because of the snow, they couldn't really clean up too much, but I did see they left behind nails and I found some plastic from the material down on my hillside, which I can't get to to throw it in the garbage.
I was not happy they were working in cold weather. I was worried they would slide off the roof.
Make sure you get everything in writing.
