What Every St. Louis Homeowner Should Know About Roofing
Primary Local Risk
Spring and summer thunderstorm cells bring frequent large hail events across the St. Louis metro
Material Recommendation
Impact-resistant architectural shingles; Class 4 impact rating recommended for the Missouri/Illinois corridor
In the City of St. Louis, a building permit is required for an entire new roof when the work is not a replacement with like material, or when more than 25 percent of the roof sheathing is removed and replaced. A roof replacement with like material that replaces 25 percent or less of the sheathing usually doesn't need a building permit. Historic properties are the exception: exterior work on buildings in the city's 14 historic districts or its 112 City Landmarks needs approval from the Cultural Resources Office, and in most instances a building permit is required even where the Building Code alone wouldn't call for one, to protect the exterior appearance of the building. Each district has its own design standards, available from the Cultural Resources Office.
Severe storms are the biggest threat to roofs here. On May 16, 2025, a tornado touched down in Clayton around 2:41 p.m. and strengthened as it moved through the northern portion of the city of St. Louis, where the National Weather Service rated it EF3 with maximum winds up to 152 mph before it crossed the Mississippi River into Illinois. The weather service's St. Louis office has documented tornado or damaging-wind events in each of the last several springs. After a storm, Missouri law adds some protections for anyone arranging roof repair in St. Louis through insurance: a contractor may not offer to pay or rebate your deductible or negotiate the claim on your behalf, and you can cancel the contract until midnight of the fifth business day after your insurer says the claim is not covered.
Missouri has no statewide licensing requirement for roofing contractors, so the check happens at the city level. Roofing companies in St. Louis operating within city limits need a Construction Industry Contractor Graduated Business License from the Office of the License Collector, which requires proof of workers' compensation coverage or a signed affidavit that the contractor is exempt, and general contractors must give the License Collector a list of the subcontractors on each job. Asking for the business license, proof of insurance and, where one is needed, the permit number is a practical way to compare roofers before signing a contract.

Emergency Stabilization (if needed)
