St. Louis experiences an average of 50 freeze-thaw cycles each winter. Water expands nine percent when it freezes. This expansion forces apart any gap it penetrates. On roofs, this means water that seeps under shingles or through inadequate flashing freezes overnight and wedges materials apart. By spring, you have leaks. New roof construction must account for this through proper ice and water shield placement and flashing details that do not rely on sealant alone. The roof systems we build use mechanical overlaps and metal flashing that block water migration even when sealants fail. This engineering approach prevents the ice dam failures and valley leaks common on roofs built without consideration for St. Louis winter conditions.
St. Louis County and St. Charles County require building permits for new roof construction. Inspectors verify proper attachment methods, fire ratings, and structural adequacy. We handle permit applications and schedule inspections at the right phases so your project does not face delays or failed inspections. Our crews understand local inspector priorities because we work with them regularly. This familiarity means your roof installation meets code requirements the first time. When you choose a local roofing company with established relationships in the permitting departments, you avoid the learning curve that out-of-town contractors face trying to navigate local requirements.
