Metal Roofing FAQs
- Can you install metal roofing over asphalt shingles?
It is possible to install a metal roof over an existing shingle roof, but you would need to use purlins. Purlins are screwed or nailed down to the roof deck, and then the metal shingles are attached to the purlins. Knowing where to install screws for metal roofing is extremely important whether you're starting at the roof deck or going over shingles. The purlins are advantageous since they provide a flat surface for installing the metal roofing panels, plus they make the roofing system stronger.
- How do you cut metal roofing?
With a metal roof installation, you won't have to cut any of the panels to length, since they'll be pre-cut or the panels will overlap each other. However, you'll need aviation snips, a double cut power shear, and a profile nibbler to cut a notch across the panels, create long straight cuts, or to cut and bend trim ends. We've provided more info on how to cut metal roofing, which is a good read for safety purposes.
