If you’re tired of patching the asphalt shingles on your roof every season, installing metal roofing material is a great way to minimize your roof maintenance costs. The roofing experts at Dixieland Metals of Alabama want you to know that, in most cases, a new metal roof can be easily installed over your old shingles. Below, they’ve compiled a few tips to help you better understand the installation process. 

Can Metal Roofing Always Be Installed on Top Of Asphalt Shingles?

Before performing any roofing work, check whether your roof has one layer of asphalt shingles or two. If you’ve invested in re-roofing services before and the roofers didn’t remove your old layer of shingles, it likely has two.

Many local ordinances state your roof can have only two layers. If this is the case, remove at least one layer of shingles. If not, check for damages or leaks before installing your metal roof.

How Is Metal Roofing Installed Over Asphalt Shingles?

Since metal roofing is so lightweight, you can install it over your existing asphalt shingle rooftop without adding much weight to your roof deck. However, before installing your metal roof, you will first need to ensure that the plywood on your roof deck is sturdy enough to support your new roof. One method is installing purlins, which create a small gap between your existing roof and the new metal roof.
