Temperature swings in Mount Vernon
Mount Vernon's July mean of 63°F is well below what a dark vinyl panel can reach in direct sun, which is part of why manufacturers warn about nearby heat sources.
January's 41°F mean, on the other end, is cold enough that a crew has to widen fastening clearances to keep panels from cracking.

Storm ratings on file for Skagit County
Wind risk in Skagit County rates Very Low and hail rates Very Low, per FEMA's county-level data.
Neither rating changes what's inside a box of siding sold in Mount Vernon, but both are good reason to ask for a panel's actual wind-load certification rather than trusting the sample board alone.

Before you sign, ask about the panel itself
- What thickness, in mils, is this panel, and does it carry an independent ASTM D3679 certification listing?
- Is this standard vinyl or insulated vinyl, and if insulated, what R-value is certified under ASTM D7793?
- What wind-load rating is the product certified for, in miles per hour, and how does that compare to {county}'s wind risk?
- Will the installer leave the manufacturer's specified expansion gap at trim, corners and openings, or nail tight?
- If the color is a dark shade, is it separately certified for color retention?
- Does any wall face reflected sunlight from a neighboring low-E window, and has that been accounted for in the material choice?
