There are several things you must consider before deciding to install a metal panel roof over an present asphalt shingle roof. The very first thing that must be determined is if the roof plywood or board board decking is solid and secure underneath the current roof. Essentially, the roof decking shouldn’t be ruined by water entering the old roofing at any pinhole or some other penetration within the field of the roof. This will require a small investigative work prior to installing the new metal roofing. It’s highly recommended, to inspect all of roof decking and framing out of the attic side of this roofing.

This should be done with great care, for one mistake can damage your ceilings or lead to significant injury to oneself. Following these things are validated to be fine, then, the next step is to start preparing the roofing.

It’s highly recommended when picking a metal roofing to consider longevity. Succinctly expressed, a hidden fastener panel is going to last the entire life of this metal with minimal chance of leaks other than failing roof penetrations over time.This is normal to all roofing types.
