Summer Storm Damage: What to Check After a Hailstorm Hits Your Roof or Siding

Summer storms in Calgary can be intense, bringing hail, heavy rain, and strong winds that can do serious damage to your home’s exterior. While hailstones may only last a few minutes, the damage they leave behind can have lasting consequences for your roof, siding and windows. Knowing what to look for after a storm is crucial to catching issues early and preventing bigger (and more expensive) repairs down the line. Here’s what you should check after a hailstorm hits your home.

Check the Roof for Obvious Impact Marks From Storm Damage

Hail can dent or crack asphalt shingles, especially on older roofs. Look for:

• Circular dark spots or bruising on shingles
• Missing granules
• Cracks or splits
• Exposed underlayment or nails

Even if your roof “looks fine” from the ground, subtle damage can compromise your roof’s ability to protect against leaks. A professional roof inspection is the best way to be sure.

Inspect Siding for Dents, Cracks, or Holes

Siding often takes a beating during hailstorms. After the storm:

• Walk around your home and inspect all sides (especially the one facing the storm)
• Look for dents, warping, or chipped paint
• On vinyl siding, check for punctures or cracks
• On aluminum siding, check for oxidation around dents

Even minor siding damage can lead to moisture getting behind your walls and causing rot or mold over time.

Check Windows and Window Frames

Hail can crack window panes, dent frames, or damage caulking. After a storm:

• Inspect glass for chips or hairline cracks
• Check wooden or vinyl frames for dents or peeling
• Look for leaks or drafts near windows (especially after wind-driven rain)

If damage goes unnoticed, it could reduce your home’s insulation and lead to water seepage.

Check Gutters, Downspouts, and Vents

Your drainage system plays a huge role in protecting your home’s structure. Hail can dent gutters or clog them with storm debris. Watch for:

• Dents or dings in metal gutters
• Detached downspouts
• Blockages or standing water
• Bent or broken vent covers on the roof

What Should I Do If I Spot Storm Damage on My Property?

If you spot storm damage on your property, the first step is to ensure your safety, avoid downed power lines, broken glass, and never climb on the roof yourself. Once it’s safe, document all visible damage with clear photos from multiple angles, including close-ups of your roof, siding, windows, and gutters. Check inside your home for signs of water intrusion, such as ceiling stains, damp walls, or drafts near windows and doors. Next, contact a trusted local roofing and exterior specialist to conduct a professional inspection and provide a detailed estimate. If the damage is significant, reach out to your insurance provider with your documentation, and consider having your contractor meet the adjuster to ensure nothing is overlooked. Finally, schedule repairs as soon as possible, delaying can lead to more serious issues. Acting quickly can save time, money, and stress in the long run.

What Happens If Storm Damage Is Left Untreated?

Leaving storm damage unrepaired, even if it seems minor, can lead to serious and costly consequences over time. The August 2024 hailstorms in Calgary caused an estimated $3 billion in damages, highlighting just how destructive these fast-moving storms can be. What may look like a few missing shingles or a small dent in your siding might not seem urgent, but these seemingly minor issues can open the door to water infiltration. Once moisture gets beneath your roof or behind your walls, it can lead to mold growth, wood rot, and structural damage—problems that are far more expensive and invasive to fix than addressing the initial storm impact. Prompt repairs are key to protecting both your home and your wallet. In some cases, delaying repairs can also void warranties or limit what your insurance will cover, especially if additional damage occurs due to inaction. In short, untreated storm damage doesn’t just stay the same, it gets worse. Addressing it early protects your home, your budget, and your peace of mind.
