At SB Roofing we often get this question: “I want to replace a shingled roof with a metal roof. I have one layer of asphalt shingles on my roof. Can I place the metal roof on top of the shingles?”
Well, the quick answer to your question is no. And there are some good reasons why. A metal roof is pretty much a lifetime product, and as such, you want to make sure that it is installed so that it never needs repairs. When you remove all of the asphalt shingles from your roof, it’s entirely possible that there may be some sheets of plywood on your roof that are not as sound as they once were for a variety of reasons. Those sheets would have to be removed and replaced by the roofer in question. There may also be some fascia boards that need replacing. Now is the time to take care of that problem, too. Once the roofing system is properly repaired, the new underlayment can be placed and the metal roofing system installed.
When the new metal roof is installed properly you will have a roof that will last almost indefinitely. Please don’t waste your money on a new metal roofing system without having it prepared and installed properly. It’s a decision you may soon regret.
