Naperville context
Exterior materials on Naperville-area homes track their construction era -- older in-town homes often carry masonry or original wood siding, while the ranch and split-level subdivisions built through the 1950s-80s commonly used early aluminum or wood siding that has since been replaced at least once. DuPage County's freeze-thaw winters and humid summers stress every exterior material differently, and the same storm systems that caused regional wind damage -- the August 2020 derecho and the March 2024 tornado that reached EF3 strength in Naperville itself -- are a reminder that impact resistance and proper flashing matter as much as appearance.
