Storms That Reached Affton, MO
National Weather Service St. Louis logged an estimated 1-inch hail report in Affton at 9:49 p.m. on March 14, 2025. It was the night an EF-2 tornado tracked from Morse Mill across Arnold, MO and Mehlville before ending at the Jefferson Barracks VA hospital, while Oakville, MO measured hailstones as large as 2 inches. Forecasters ranked that outbreak among the busiest the St. Louis area has on record.
On May 16, 2025, NWS received a photo of a damaged carport about a mile north-northwest of Affton. That wind report stood apart from the EF-3 tornado of the same day, which stayed well north of here.
State Farm's 2025 hail claim totals put Missouri at number two nationally.
Permits for an Affton, MO Re-Roof
Because Affton has no city government, building permits come from St. Louis County Public Works, the same office that serves Oakville, MO. Under §105.1.2 of the County building code (Ordinance 27,654), two kinds of roof work need a permit: re-roofing any section pitched below 4:12, and switching materials, for instance from asphalt to a metal system.
Don't assume the answer for other jobs either way. Your roofer should confirm the requirements with the County before work starts and pull any permit the job needs.

Questions Asked in Affton, MO
Does a re-roof in Affton need a permit?
It depends on the job. With no city government, Affton relies on St. Louis County Public Works for permits. The County names two triggers: a roof flatter than 4:12, and a switch in roofing material. Ask your roofer to confirm with the County and handle any permit.
Did the March 2025 storms reach Affton?
Yes. NWS St. Louis recorded an estimated 1-inch hail report in Affton on the night of March 14, 2025. Has nobody looked at the roof since then? A free inspection will tell you whether the shingles held up. Hail bruises and lost granules are often hard to spot from the yard.
Will an Affton roofer talk to my insurer on my behalf?
Not as your representative. RSMo 407.725 keeps roofers out of claim negotiations. The roofer can photograph, measure and price the damage, and settling the claim is between you and your insurance company. A licensed public adjuster can act for you; Missouri's insurance line is (800) 726-7390.
Are Class 4 shingles worth it in Affton?
They are a choice, not a rule; nothing in St. Louis County requires them. This Old House suggests impact-rated Class 4 shingles for homes in Missouri. Ask the roofer to quote both kinds, and ask your insurance agent how each would affect your coverage.
