Hi Everyone-I just joined the Alliance and this is my first post. I just had my roofer install a Union Corrugating Co. metal roof on my 28 x 60 shop building. Not sure of the roof pitch but it is not steep. The building is built like a ranch style house of the same dimensions. My roofer used 26 gauge Union Master Rib roof panels. Here is my question.... one side of the roof they laid the panels down from right to left (started at the front of building working to the rear). On the opposite side they laid the panels down right to left (starting at the rear of the building and working to the front). Is this a standard practice to do this or just another correct way to skin a cat? So on one side the seams go against prevailing winds and on the other side they are facing prevailing winds. So does it really matter? Just preference? Work faster? Just wondering. I am not a roofer but like to know and learn as much as possible. Thanks in advance for your replies!
Any takers? Do any of the moderators or experts have any thoughts or insight related to my question?
As long as the panels are lapped properly (the correct edge is on top), which is possible if directionality was switched, this is fine. They may have done this so as to avoid predominate winds from blowing into the laps.
