Metal roof over shingles is a popular installation these days, but it can be difficult to choose the right underlayment.
Metal roof underlayments are designed to cushion the blow of high winds, protect your home from moisture, prevent ice dams from forming, and provide insulation.
The main consideration when selecting underlayment for your metal roof over shingles is the type of roof you have.
For example, if your metal roof is lightweight, like tin or steel, you can usually get away with putting down asphalt felt. However, stronger metal, like galvanized steel or a copper roof, will require something more substantial like fiberglass or felt.
To get the right underlayment for your metal roof over shingles, you'll have to consult with your roofing contractor.

Best underlayment for metal shake roofs over shingles.

If you are a homeowner who is planning to install metal roofing over shingles, you will need to install an underlayment on the bottom of your metal roofing panels. This is an added layer of protection that will protect against leaks and damage. 

There are two types of underlayments available that you will need to take into consideration: 

Felt underlayment: this is a common type of underlayment that will protect your roof from leaks. However, felt underlayment is not very durable and does not provide much in the way of soundproofing - if you have loud neighbors or a noisy home environment, it may actually make your metal roof louder than if you had installed your roofing material directly over the shingles. 

Rubber underlayment: rubber underlayment is more expensive but more durable than felt underlayment. It is created from a rubber compound that is then glued to a mat. When installed properly, rubber underlayment can add extra soundproofing while preventing leaks.
