Vertical Panels in very cold weather | General Discussion | Archive | Ask The Experts Forum

Hello, we are shopping around for a new metal roof and were informed by one salesperson that vertical panels compared to metal shingles expanded and moved many inches in very cold weather. We live in Montreal, Canada so we are wondering if this could cause a problem. Thank you.		Guest User 10/4/2005	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/6823/find/
Quality metal roofs typically have some sort of allowance built-in for expansion and contraction. This is less of an issue with smaller panel roofs.		Todd Miller Isaiah Industries, Inc. 10/5/2005	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/6824/find/
