After Summer Storms in Lake County, IL: 7 Things Homeowners Should Inspect Before Fall

Aug 10
6 min read

Summer storms in Northern Illinois can bring heavy rain, strong winds, hail, falling branches and sudden changes in weather. Even when a home looks fine immediately after a storm, exterior damage is not always easy to see from the ground.

That is especially important for homeowners in Libertyville, Lake Forest, Vernon Hills and surrounding Lake County communities after the severe weather that moved through the area on July 27, 2026.

The National Weather Service issued severe thunderstorm warnings for Lake County with potential wind gusts reaching 70 mph and hail up to 1.5 inches in diameter. Libertyville, Lake Forest, Vernon Hills, Gurnee, Grayslake, Lake Villa and several surrounding communities were included in the affected area.

Heavy rainfall was also recorded throughout Lake County, including more than 2 inches near Libertyville and significant rainfall around Lake Forest and Vernon Hills.

Before fall and winter weather arrives, now is a good time to walk around your property and check for signs that your home's exterior may need attention.

Here are 7 areas Lake County homeowners should inspect after severe summer storms.

1. Check Your Siding for Storm Damage

Siding is your home's first line of defense against wind-driven rain, hail and changing temperatures.

Strong winds can loosen individual pieces of siding, while hail can leave dents, cracks or impact marks that may not immediately look serious.

Walk around your home and look for:

Loose or missing siding
Cracks or dents
Warped panels
Damage around corners
Gaps between siding sections
Areas pulling away from the house
Water stains or moisture behind siding

Damage should not be ignored. Even a relatively small opening can allow moisture behind the exterior surface, potentially affecting insulation, sheathing and other parts of the structure.

State Construction provides professional siding installation throughout Libertyville, Lake Forest, Vernon Hills and Lake County, IL, including exterior solutions designed for durability and long-term protection.

2. Inspect Windows and Window Trim

Windows can also take significant punishment during severe thunderstorms.

High winds place pressure on windows and frames, while hail or flying debris can damage glass, screens, exterior trim and seals.

Look carefully for:

Cracked glass
Damaged screens
Loose exterior trim
Gaps around window frames
Moisture between panes
Water stains inside the home
Windows that suddenly become difficult to open or close

One important warning sign is water appearing around a window after heavy rain.

The problem may not always be the glass itself. Water can enter through damaged flashing, exterior trim, siding or gaps around the window opening.

If you are considering replacing older or damaged windows, professional window installation can also improve comfort, appearance and energy efficiency.

3. Look Closely at Your Deck

Your deck may look strong, but storms combined with years of exposure to rain, snow, heat and freezing temperatures can weaken outdoor structures over time.

After heavy storms, check your deck for:

Loose boards
Splintering or cracked wood
Soft or rotting areas
Loose railings
Movement in stairs
Damaged posts
Water pooling
Debris trapped against the structure
Signs that the deck has shifted

Pay particular attention to railings, stairs and structural connections.

These are areas where minor deterioration can eventually become a safety concern.

For homeowners considering a larger upgrade, replacing an aging wood deck with modern composite decking can create a more durable and lower-maintenance outdoor living space.

State Construction builds and renovates decks throughout Lake County and Northern Illinois, including projects in Lake Forest, Libertyville, Antioch and surrounding communities.

4. Inspect Exterior Trim, Soffits and Fascia

Small exterior components are easy to overlook after a storm.

Wind can loosen trim boards, soffits and fascia, while heavy rain can expose areas where wood has already begun deteriorating.

Walk around the house and check for:

Loose trim
Missing pieces
Peeling paint
Soft or deteriorated wood
Open seams
Visible gaps
Signs of moisture

These areas help protect the edges and transitions of your home's exterior.

Repairing damaged exterior components early can help prevent moisture from reaching areas that are more expensive and difficult to repair later.

5. Check Garages and Other Exterior Structures

Detached garages, attached garages, sheds and other structures should also be inspected after severe weather.

The July 27 National Weather Service warning specifically noted the potential for wind damage to roofs and outbuildings in the affected Lake County area.

Check garage siding, doors, windows, trim and framing for anything that appears loose, shifted or damaged.

Also look around the foundation and garage floor for signs of new water intrusion.

If you have been considering building or replacing a garage, storm season can also reveal weaknesses in older structures and help determine whether continued repairs make sense or a larger renovation would provide better long-term value.

6. Look for Water Intrusion Inside the Home

Some of the most important storm damage signs appear inside, not outside.

After a period of heavy rainfall, inspect areas near exterior walls, windows, ceilings and lower levels.

Look for:

New water stains
Damp drywall
Bubbling paint
Musty odors
Wet insulation
Moisture around windows
Basement water
Discoloration on ceilings or walls

Water does not always enter directly above the place where you see the stain.

It can travel behind walls, along framing or around windows before becoming visible.

If water intrusion is connected to damaged siding, windows, trim or another exterior component, finding the source early can help prevent a small problem from becoming a much larger renovation.

7. Walk the Entire Property Before Fall

One of the easiest things homeowners can do is simply walk around the entire property after a major storm.

Look at the house from different angles.

Check the siding.

Look around windows and doors.

Inspect the deck.

Check the garage.

Look for fallen branches or debris that may have struck the home.

Pay attention to anything that looks different than it did before the storm.

You do not need to identify every technical problem yourself. The goal is to notice changes early enough to have suspicious areas evaluated before another season of rain, freezing temperatures, snow and ice arrives.

Why Inspect Your Lake County Home Before Fall?

Northern Illinois homes experience demanding weather throughout the year.

Summer brings thunderstorms, high winds, hail and heavy rain. Fall brings temperature changes and additional moisture. Winter adds freezing conditions, snow and ice.

Damage that seems minor in August can become much more noticeable once water enters an opening and temperatures begin to freeze.

That is why late summer and early fall are excellent times to inspect your home's exterior and complete necessary improvements.

For homeowners planning larger projects, this can also be a good time to evaluate whether aging siding, windows, decks or exterior structures should be repaired, replaced or incorporated into a larger home renovation.
