Snow and metal roofing near Union City
Normal January temperatures near Union City average 51°F, cold enough that freeze-thaw cycling is a real factor for any roof material.
A standing seam panel's sealed seams handle Union City's freeze cycling differently than an exposed-fastener panel's washers do, which age and compress over repeated freezes.
Ask an installer how they've handled panel expansion on a Union City winter before you commit to a system.
