Question Another layer of shingles?

Can I put a second layer of shingles over my current three tab shingles? They are slightly curled, perhaps 1/4" from the roof in places. I plan on putting dimensional shingles down. The roof pitch is 6/12.

Bob, if you'll search the archives you'll find several lively discussions on the topic. The short answer is yes, but it comes with lots of strings such as condition of roof, ventilation, etc. and of course it has to be allowed by your local building codes.
