Calgary is no stranger to wild summer weather. When a major storm rolls through, the immediate aftermath usually involves checking your car for dents or clearing the driveway of shredded leaves. But while automotive damage is impossible to miss, the impact on your roof isn’t always visible from the ground – and that’s exactly how small leaks turn into costly structural headaches.
If a storm just swept through your neighbourhood, waiting until next spring to check your shingles is a big gamble. Here is exactly what you need to know about spotting hidden damage, documenting evidence, and booking roof inspections for hail damage in Calgary to protect your home.
How Hail Actually Damages a Calgary Roof
Asphalt shingles are designed to handle heavy snow and wind, but high-velocity hail punches right through their primary defences. When we perform a roof inspection after hail in Calgary, we primarily look for three hidden signs of structural compromise:
- Granule Loss: Hailstones act like sandpaper, knocking away the granule coating on your shingles. If you notice dark patches on your roof or find piles of black, sand-like debris piling up at the bottom of your downspouts, your shingles have lost their UV protection. Without granules, the underlying asphalt layer bakes in the sun, becomes brittle, and cracks.
- Bruising: This is the most deceptive type of damage. A shingle might look perfectly flat from a distance, but underneath, the impact has broken the fibreglass matting. These spots can feel soft or spongy, similar to a bruised apple. Over time, these soft spots fail completely, allowing water to seep through.
- Cracks and Fractures: Large hailstones cause circular or straight-line fractures directly through the shingle body. These fractures immediately shatter the waterproof barrier, giving the next rainfall a direct pathway into your attic.
The Step-by-Step Post-Storm Roof Inspection Process
You shouldn’t immediately grab a ladder and climb onto a slick, potentially damaged roof after a storm. Instead, follow a strategic, safety-first inspection process.
1. Start on Safe Ground
Grab a pair of binoculars and walk the perimeter of your yard. Look for obvious signs from ground level:
- Dented metal valley flashing, fascia, or eavestroughs
- High-impact marks or holes on soft plastic roof vents and ridge caps
- Missing, torn, or severely misaligned shingle pieces scattered across the lawn
2. Clear Away Exterior Debris
Before anyone can fully evaluate a roof’s surface, the work area needs to be clean. Safely clear away heavy tree branches, loose debris, or large pileups of hail chunks from the perimeter of your home. Clogged, broken gutters trap standing water against your lower roofline, which rapidly accelerates water damage after a storm.
3. Document the Evidence Immediately
If you spot signs of an impact, grab your smartphone and create a high-resolution paper trail for your insurance provider. Take wide and close-up photographs of:
- Dented downspouts, air conditioners, or window frames
- Any shredded roofing materials on the ground
- The actual size of the hailstones alongside a reference object like a coin, if possible
- Note the exact date and time the storm hit
4. Cover Vulnerable Spots Temporarily
If the storm was severe enough to leave open holes or fully exposed plywood on your roof, you must act fast to prevent indoor water damage. Secure a temporary tarp or plastic sheeting over the exposed gaps. If you aren’t comfortable doing this safely, reach out to local roofing emergency services to handle it for you.
When to Call a Professional
While a ground check is a great first step, it can’t replace a physical, close-up assessment. If your neighbourhood was hit by hail larger than a nickel, or if you spotted any of the warning signs listed above, it’s time to call in a certified expert.
Professional roof inspectors know how to spot subtle bruising, check the structural integrity of your attic ventilation, and identify hidden micro-fractures around chimneys and skylights before the next freeze-thaw cycle hits. We also provide a detailed report and documentation that your insurance adjuster needs to approve your claim.
