After a summer of heavy rain, strong winds, hail, and thunderstorms, your home’s exterior may have small areas of damage that aren’t immediately noticeable. A few missing granules, a lifted shingle, a small dent in your siding, or a damaged gutter may not seem like a major concern today but these problems can become much more serious once winter arrives. For homeowners throughout Minnesota, Wisconsin, and Iowa, fall is an ideal time to inspect your home for hidden storm damage and address potential problems before snow and freezing temperatures set in. Here are some of the most common signs to look for. 1. Look for Missing or Damaged Roof Shingles our roof takes the brunt of severe weather. Strong winds can loosen or lift shingles, while hail can crack or damage the surface. Some damage is easy to spot, but other problems may be subtle. From the ground, look for: Missing shingles Shingles that appear lifted or out of place Curling or buckling Cracked or broken shingles Dark or unusual spots Areas where the roof looks uneven Even one damaged shingle can create an opportunity for water to enter your roofing system. If you’re unsure whether your roof was affected by a recent storm, a professional inspection can help identify damage that may not be visible from the ground. 2. Check Your Gutters for Signs of Roof Damage Your gutters can sometimes tell you more about your roof than you might expect. After a storm, check your gutters and downspouts for excessive amounts of asphalt granules. While some granule loss is normal, a sudden increase after a hailstorm or severe weather event may indicate that your shingles have been damaged. Also look for: Dents or impact marks Bent or loose gutter sections Sagging gutters Leaks Damaged downspouts Debris buildup Because gutters sit directly below the roofline, they can also collect debris or damaged roofing materials after a storm. 3. Inspect Your Siding for Hail or Wind Damage Storm damage isn’t limited to your roof. Hail and strong winds can damage siding, particularly on the sides of your home that receive the most exposure. Walk around your property and look for: Small dents or dimples Cracks Chips Holes Loose panels Panels that have shifted Scratches or impact marks Hail damage can sometimes be difficult to see unless you’re looking closely. Changes in lighting can also make dents and impact marks easier to notice. If you suspect your siding has been damaged, have it professionally evaluated before winter weather arrives. 4. Look Around Windows and Doors Windows and exterior doors can also be affected by severe weather. Hail can damage glass, frames, screens, and surrounding materials. Strong winds may also loosen seals or create gaps around the openings. Check for: Cracked glass Damaged screens Loose trim Cracked caulking Gaps around frames Signs of moisture Damaged weatherstripping Small gaps around windows and doors can become especially noticeable once cold temperatures arrive. Addressing them in the fall can help prevent moisture and cold air from entering your home during winter. 5. Check Your Garage Door Garage doors can be surprisingly vulnerable during severe weather. Hail can leave dents in the panels, while strong winds or flying debris can damage the door’s exterior or components. Look for: Dents or impact marks Cracked or damaged panels Loose hardware Damaged weatherstripping Gaps around the door Difficulty opening or closing If your garage door isn’t sealing properly, cold air, snow, and moisture can enter the garage throughout the winter. 6. Look for Water Damage Inside Your Home Not all storm damage is visible from the outside. After heavy rain or severe weather, check your attic and interior ceilings for signs that water may have entered your home. Watch for: Brown or yellow ceiling stains Damp insulation Discoloured walls Peeling paint Musty smells Moisture around vents or chimneys Water stains in the attic A small water stain may indicate a roofing issue that needs attention. The longer moisture remains undetected, the greater the potential for damage to insulation, wood, drywall, and other materials. 7. Inspect Your Roof Flashing Flashing is used around vulnerable areas of the roof, including chimneys, vents, skylights, and roof edges. Severe weather can loosen or damage flashing, creating areas where water can enter. During a visual inspection, look for: Loose flashing Cracks Rust or corrosion Missing sections Damaged sealant Gaps around roof penetrations Because flashing protects some of the most vulnerable areas of your roof, even a small problem shouldn’t be ignored. 8. Check for Fallen or Damaged Tree Branches Strong winds can cause branches to fall onto roofs, gutters, siding, and other parts of your home. Even if a branch didn’t cause obvious damage, inspect the surrounding area for signs of impact. Pay particular attention to: Broken or cracked shingles Dented gutters Damaged siding Scratches or impact marks Broken vents Damaged exterior fixtures Trees that hang over your roof should also be evaluated before winter. Heavy snow and ice can add additional weight to branches and increase the risk of them breaking. 9. Don’t Ignore Small Problems One of the biggest mistakes homeowners can make after a storm is assuming that minor damage isn’t worth addressing. A small opening in your roof can allow moisture into the roofing system. A loose piece of siding can become worse during strong winter winds. A damaged gutter can allow water to drain where it shouldn’t. Winter weather can put additional stress on these already weakened areas. Addressing problems in the fall can help prevent a small repair from becoming a much larger project later. Why Storm Damage Can Be Hard to Spot Not all storm damage is dramatic. Hail can leave small impact marks that are difficult to see. Wind can lift shingles without completely removing them. Water can enter through a small opening and travel before becoming visible inside your home. That’s why a roof or exterior can appear fine from the ground while still having damage that deserves attention. A professional inspection can help identify areas that may be easy to miss during a basic visual check. What Should You Do If You Suspect Storm Damage? If you believe your home may have been damaged during a recent storm, start by documenting what you see. Take photos of visible damage and make note of when you first noticed the problem. Avoid climbing onto the roof yourself, especially if you’re unfamiliar with roof safety. Instead, have a qualified professional inspect the affected areas. If you have homeowners insurance and believe the damage may be storm-related, you may also want to contact your insurance provider and ask about the appropriate next steps. Don’t Wait Until Winter to Inspect Your Home Fall is one of the best times to address storm damage. Once snow, ice, and freezing temperatures arrive, existing problems can become more difficult to repair and may lead to additional damage. A fall inspection gives you an opportunity to identify concerns while the weather is still manageable and before your home has to withstand another season of harsh winter conditions. Whether the damage is on your roof, gutters, siding, windows, or garage door, finding it early can make a big difference.
