Insulation Under New Roof | Ask The Experts Forum

Guest User 7/25/2007	I am currently building a new house and plan to use a standing seam metal roof. The manufacturer calls for a 3" foam between the decking and the metal roof. The builder and I feel this is a huge waste of money since foam insulation is expensive and the attic spaces are already insulated. Is this "double insulation" necessary? Thanks.

Todd Miller Isaiah Industries, Inc. 7/25/2007	I am assuming you have a vented and insulated attic space. If that is the case, I see no reaosn for this extra insulation.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/9893/find/
Guest User 7/26/2007	Thanks Todd Yes, not sure if we will be using fiberglas or blown in, but the attic will be insulated above the ceiling joists and vented, probably on the gable ends. Is this a good solution with the metal roof? There are no cathedral ceiling areas and the house will have exposed rafter tails.
