Can metal roofing be installed over existing fiberglass shingles? Will this present any problems?		Guest User 11/4/2005	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/7033/find/
Most metal roofing products are but the building code does have certain restrictions as to layers and type of overlay and now with hail zones. Also ask to see the product approval which will indicate that it has been tested and approved for this application as there are wind, fire and rain issues as well to consider.
