Should I have my old roof removed before the new one is installed?

Frequently Asked Roofing Questions - Roof Helper
Should you remove your current roof before installing another? Although the advantages to leaving your old shingles are obvious (cheaper, less labor, faster), unless the initial roof is a single, problem-free layer, you could be setting yourself up for trouble. The new roof is of a lighter material than the original roof. If you put lightweight shingles over heavyweight shingles, all of the old bumps and ridges from the original roof will still show.

Is it necessary that my present roof be removed before a metal roof is installed?

Metal Roofing Frequently Asked Questions | Best Buy Metals
In most applications over asphalt shingles, our metal roofing can be applied over the old roof with 30lb felt underlayment or 1'x4' lathing boards installed between the existing roof and the new metal roof. This saves money and time. In addition, because there is no old roof to remove, landfill space is spared, helping to protect our environment.
