Standing Seam Galvanized warping?

Guest User
Our standing seam galvanized roof is about 3 years old and I am starting to see some warping or waves in areas. We are in an area of Texas where we have freezing in winter and 100+ degree temps in the summer. We are also on the side of a canyon where we frequently experience high winds. Is this warping a normal condition? How much could be considered normal? Thanks.

Michael, This is very difficult to diagnose without pictures and without being there. If you like, email me pictures to my email address. This could be due to a problem with the roof decking (or lathe board if that is the case). If it is, the problem could be the result of improper decking installation, a roof leak, or inadequate attic ventilation. This also could be the result of mis-application of the roofing. Or you might be seeing some "oilcanning" which is a sort of natural occurrence that can affect standing seam at any time but especially when expansion and contraction occur due to temperature swings and high temperatures. I suggest you contact the roofing manufacturer for their opinion or have an experienced metal roofing contractor come out to inspect the situation.
