Alta Loma's winters and panel choice
Normal January temperatures near Alta Loma average 56°F, cold enough that freeze-thaw cycling is a real factor for any roof material.
A standing seam panel's sealed seams handle Alta Loma'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 Alta Loma winter before you commit to a system.
