Installation recommendations | Ask The Experts Forum

Linda DuBois 12/9/2016	I am planning on installing a new metal roof this spring and would like to know what is recommended. I have talked to several contractors about the installation and have had different opinions on the subject. My roof is 20 plus years old with a double layer of shingles. The shingles are damaged and not laying flat. What would your recommendations be for the installation?	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/21689/find/

Linda DuBois 12/9/2016	I am looking at applying the metal over the existing two layers of shingles. I need to know if underlayment and furring strips should be used in the installation. I am getting different opinions from the contractors.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/21691/find/

Eric Novotny An informed customer is the Best Customer! 12/10/2016	You should review the literature and requirements that are specific to the panel manufacturer, however, a slip layer is always required in some capacity. This is not to control vapor diffusion in this case and much more about protecting the back of the metal panel.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/21695/find/
