Vinyl siding cracks at the nail hem after freeze-thaw cycles
Why it happens here
Blue Ash Business District swings from 95 degrees in summer to 5 degrees in winter. Vinyl expands and contracts, and panels crack at the nail hem or pull loose at the J-channel. Builder-grade vinyl is the most vulnerable.
Our approach
We install vinyl with oversized nail slots and set siding nails to manufacturer depth so panels can move. We use CertainTeed and Mastic vinyl rated for cold-weather impact. We also seal with caulk at joints and corners.
