What is the adv or disadvantage of Standing seam over the PBR and what would the warranty difference be?	Ross Greer SCBC 11/20/2006	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/8928/find/
Standing seam systems have concealed fasteners and usually have allowance for expansion and contraction of the metal. This contrasts with a through-fastened panel like PBR.	Todd Miller Isaiah Industries, Inc. 11/23/2006	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/8929/find/
I live in a large townhouse complex that has many barrel topped units, approximately 14-16 feet wide. The roofs are currently covered in what looks like a metalized material layed lengthwise versus crossing the barrel. Two questions: Would you recommend standing seam at all, and if so layed lengthwise, with seams parallel running the length of the roof, or across the barrel arch. Tha later would require a cosistent variable flex across each panel, thwile the former would only have to flex across its section. Do you have a recommendation of a particular brand and should we be consulting a commercial versus residential vendor/contractor? That's more than two questions, but thanks for any help you can provide.

Standing seam would need to go across the arch which means you need a curved panel. MRA member manufacturers you may wish to contact include ATAS International and Fabral.	Todd Miller Isaiah Industries, Inc. 3/4/2007	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/8931/find/
