Installation over existing shingles | Ask The Experts Forum

Guest User 5/21/2005	I was wondering, can you install a metal roof over exising shingles? If so, this would make my like a lot easier.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/5917/find/
Todd Miller Isaiah Industries, Inc. 5/21/2005	Metal roofing weighs much less than standard shingles. Most residential metal roof systems are designed to be installed over existing shingles, saving the cost and mess of old roof removal and disposal. I always suggest a new underlayment between the two layers of roofing though.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/5918/find/
Guest User 5/31/2005	What if the metal is 24 guage and the old composite is in 2 layers? I have been advised that the composite should be removed due to its weight, but a respected roofer says the composite will not have to be removed. The home is a sturdy, brick structure over 30 years old.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/5919/find/
Todd Miller Isaiah Industries, Inc. 5/31/2005	In most areas, building codes prohibit more than two layers. From a practical standpoint, though, there are always possible conditions which could prevent this but, generally, your installation as described is probably feasible. Check with the manufacturer of the new roofing and see what they say since they will know their product better than I do.

Guest User 7/6/2005	Can you apply metal roofing over existing metal roofing? Existing sheathing is skipped 1 X 6.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/5921/find/
