Metal over fiberglass shingles

Always adhere to applicable building codes. Always check with your metal roofing manufacturer. A responsive and caring manufacturer will even ask you to send photos of the current roof. While an ideal roof would probably not be over the old shingles, this is done successfully with metal products on a regular basis. The low weight of metal and the design of metal products encourages application over old shingles.

I have 3 tab 25 year fiberglass shingles that will not seal after 15 years and are starting to buckle at the joints. If I install metal roofing, will I have to remove the old roofing down to the wood and will the condition of the existing roof affect the warranty of the metal roof if I install it over the shingles?

+1 to Todd's advice. Metal can easily accommodate your requirements and will do just fine in that application. Check with the supplier for specifics.
