new installed shingle roof wavy


I just have my old roof removed and new roof installed by a contractor, but the new roof looks wavy. The contractor told me it's because it's winter now and the shingles are shrunk and they will flat when temperature gets quite warm. I'm fishy about the explaination. Could someone give me any advice before I pay several thousand dollors? I appreicate your help very much.

Lucy, there are literally dozens of threads on this very topic. A quick search will give you all the info you would need. Plus, a picture is worth a thousand words & wouuld give the experts here a much better idea of what is going on with your roof.

Your contractor is telling you the truth, well, at least as far as I can tell...........shingles laid when it is cold out typically take some time to "lay" down and seal.......they need the warmth of the sun to make them seal properly. They should be fine as long as you don't get an awful wind storm.

Good hot day and they should lay flat relatively quickly.

I try to shy away from doing roofing if its below 50* F for that exact reason. Get a few days of sunny and 50-55 + and they will lay flat. When its cold the shingles cant "bond" to one another so to speak. Once its warm enough and the shingles warm and become pliable again, they will lay flat and look MUCH better than they do now. If you think it LOOKS bad because it was laid cold, try WORKING with shingles in 35-40* weather .

Lucy, the shingles will flatten as the temperature goes up. I would keep an eye on it. It the shingles don't flatten completely your might have under driven nails or slanted nail heads which might be lifting your shingles.
