St. Louis averages 20 to 30 freeze-thaw cycles each winter. The temperature drops below 32 degrees overnight, then climbs into the 40s or 50s by afternoon. That cycle makes your roof decking contract and expand repeatedly. Each cycle loosens the grip between the nail shank and the wood fibers. By spring, you have multiple nails that have backed out a quarter inch or more. Homes near the Missouri River or Meramec River face even more cycles because of the humidity those waterways generate. Fixing roof nail pops in spring prevents summer storms from driving water into your attic.
Pioneer Roofing St. Louis has repaired nail pops in every St. Louis neighborhood, from historic districts like Benton Park to newer subdivisions in Oakville. We know which roof styles are prone to fastener failure and how local contractors cut corners during installation. St. Louis building inspectors require ring-shank nails for roof decking, but some builders still use smooth-shank nails because they are cheaper. Those nails pop within five years. We identify those installation mistakes during our inspection and give you a realistic repair plan. Local expertise matters when your roof is on the line.
