Can I place aluminum roofing over existing shingles ? Should I use roofing felt between the old roof and the aluminum ?		Guest User 7/21/2008	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/11799/find/
I always suggest underlayment between the two. The answer to your question is generally yes but it depends a lot upon exactly what profile and type of aluminum roofing is being installed. The best thing you can do is to check with the manufacturer and see what they say.
