St. Louis sits in a humid continental climate where spring and summer storms routinely drop large hail across neighborhoods like Tower Grove South, Benton Park, and Forest Park Southeast. These impacts dent aluminum and crack vinyl on homes built before the 1960s, especially those with original wood sheathing that has softened over decades. Replacement crews must check for hidden water intrusion behind the siding because freeze-thaw cycles in winter push moisture deeper into the walls.
Many two-story brick and frame houses in Shaw and The Hill have narrow setbacks and shared lot lines that limit staging space for scaffolding and material drops. Crews often work from the alley side or coordinate with neighbors in Carondelet and Downtown to avoid blocking streets during removal. Matching the new siding profile to older courses requires pulling samples from multiple elevations because sun exposure and prior repairs have created slight color shifts across a single elevation.
Insurance adjusters in University City and Webster Groves frequently request line-item documentation of underlayment, flashing, and housewrap replacement. Skipping these steps leaves seams that leak during the next heavy rain, particularly on south-facing walls that take the brunt of summer storms rolling in from the Missouri River valley.
Technician insight
In St. Louis the thing that catches most people out with hail-damaged siding replacement is the hidden rot behind original wood sheathing on homes in Lafayette Square and Benton Park. Those narrow lots and shared walls mean you cannot just rip everything off without checking the neighbor side first, and spring storms hit again before the job is buttoned up.
Hail Strike on South-Facing Wall
A 1920s frame house in Shaw showed rows of dents after a May storm. Inspection found water stains along the bottom plates where older sheathing had absorbed moisture. Crews replaced only the damaged courses, renewed the flashing at each window, and added new housewrap behind the repair area. The south elevation now matches the untouched sides and has withstood the following winter freeze-thaw cycles without further intrusion.
