“Can you install metal roofing over shingles?” It’s a question we hear all the time. Fortunately, the answer is yes, you can install metal roofing over shingles! There are quite a few notable advantages to installing metal roofing over your old shingle roof, including durability, long-term cost, and energy efficiency. Installing metal roofing directly over your home’s old shingles is a great option for homeowners who don’t want to go through the chaos of removing the shingles first, which can be a messy and time-consuming process.

There are a lot of great reasons to install metal roofing over your home’s shingles — to make the switch even easier for you, we’ve put together this guide to provide you with all the information you need.

Different areas may have different laws about when you can and can’t install a metal roof over a shingle roof. Most of the time, you should have no issues installing metal roofing over shingles. However, there are some cases in which you may not be permitted to do so, such as when there are already more than two layers of roofing materials in place and weight is a concern.

Next, you’ll need to verify that your shingle roof is in acceptable condition to have a metal roof installed on top of it. There are a few different ways to install metal roofing on top of shingles, but every method involves screwing or nailing materials directly into the old roof.

Your metal roof needs a sturdy shingle roof in good condition to support it. Luckily, metal roofs are lightweight, so you should be fine as long as your shingle roof isn’t showing signs of significant damage.
