Tornadoes
Risk profile
Illinois sees tornadoes from spring supercells and summer squall lines, with risk spanning farm towns, Chicago suburbs, and older masonry neighborhoods.
Home prep before the event
Before severe-weather season, choose the lowest interior room or a properly designed safe room, keep shoes, helmets, phone chargers, flashlights, and a weather radio there, and clear the path at night. Anchor tall furniture and know how to shut off gas and power after damage.
During-event safety
During a warning, go immediately to the shelter room, cover your head and neck, and stay away from windows, garage doors, and large-span rooms. Do not drive to inspect damage until warnings expire and downed-line hazards are known.
Post-event recovery
After a tornado, stay out of unstable structures, photograph damage from several angles, save roof covering samples if safe, and have utilities cleared before restoration starts. Ask the insurer before removing major debris, and keep contractor licenses, estimates, and receipts together. Use FEMA's IL page at https://www.fema.gov/locations/illinois if a federal disaster is declared, and monitor Illinois Emergency Management Agency and Office of Homeland Security at https://iemaohs.illinois.gov/ for state recovery centers, debris rules, shelter updates, and mitigation programs.
Code references
Code reference: residential safe rooms and storm shelters should follow ICC 500 and FEMA P-320/P-361 guidance; see https://www.fema.gov/emergency-managers/risk-management/building-science/safe-rooms/resources. IBC 423 shelter mandates apply to some community and critical buildings, not every existing house.
Freezes and winter cold snaps
Risk profile
Illinois freeze risk includes subzero wind chills, ice dams, frozen service lines, and sump-pump discharge lines blocked by snow or ice.
Home prep before the event
Before a freeze, insulate exposed pipes, disconnect hoses, cover hose bibs, seal crawlspace air leaks without blocking required combustion air, test heat, replace dirty filters, and learn the main water shutoff. Keep battery CO alarms working before using fireplaces, generators, or backup heat.
During-event safety
During the freeze, keep safe heat operating, open cabinet doors at vulnerable sinks, let a thin stream run only if local officials allow it, and never heat pipes with a torch. Shut off water if a pipe bursts and avoid standing water near electricity.
Post-event recovery
After a freeze loss, shut off the source, photograph burst pipes and soaked materials, remove standing water quickly, and keep receipts for plumbers, drying, and temporary heat. If an outage or statewide emergency drove the damage, document outage dates and official notices. Use FEMA's IL page at https://www.fema.gov/locations/illinois if a federal disaster is declared, and monitor Illinois Emergency Management Agency and Office of Homeland Security at https://iemaohs.illinois.gov/ for state recovery centers, debris rules, shelter updates, and mitigation programs.
Code references
Code reference: existing-home freeze prep is usually maintenance, but permitted repairs follow the local residential, plumbing, mechanical, and fuel-gas codes. Where adopted, IRC P2603.5 requires water, soil, and waste piping to be protected from freezing.
Straight-line wind storms
Risk profile
Illinois windstorms include derechos, bowing squall lines, and winter frontal winds that damage shingles, siding, mature trees, and service drops.
Home prep before the event
Before high-wind season, inspect roof edges, soffits, gutters, fences, trees, garage doors, and overhead service masts. Move loose furniture, grills, and trampolines before warnings arrive, and photograph exterior conditions so insurance adjusters can distinguish new storm damage from older wear.
During-event safety
During high wind, stay inside and away from windows, skylights, and rooms under large trees. Do not touch downed lines, and avoid opening garage doors or exterior doors while peak gusts are hitting the house.
Post-event recovery
After a windstorm, photograph roof slopes, gutters, siding, fences, tree impacts, and damaged service equipment before cleanup. Use emergency tarps only when safe, keep tree-removal receipts, and have electrical service masts or weatherheads inspected before reconnect. Use FEMA's IL page at https://www.fema.gov/locations/illinois if a federal disaster is declared, and monitor Illinois Emergency Management Agency and Office of Homeland Security at https://iemaohs.illinois.gov/ for state recovery centers, debris rules, shelter updates, and mitigation programs.
Code references
Code reference: high-wind repairs normally use the adopted IBC/IRC, ASCE 7 wind loads, manufacturer installation instructions, and local reroof or siding permit rules. Structural roof sheathing, garage doors, service masts, and connectors should be inspected before replacement.
Plan the repair before the next warning
Use this guide to prioritize inspections, then compare licensed local contractors before the emergency queue fills after the next storm, freeze, heat wave, flood, or fire.
