After a hailstorm rolls through, itās natural to inspect your home for visible signs of damageābut when it comes to your roof, itās not always easy to spot. Hail damage on asphalt shingles can range from obvious to subtle, and missing it could cost you thousands in repairs if leaks develop later or insurance claims are denied.
So, what does hail damage actually look like? Letās break down the signs, how to spot them, and when to call a professional for help.
š§ Why Asphalt Shingles Are Vulnerable to Hail
Asphalt shingles are durable, but not invincible. When hailstonesāespecially those larger than 1 inchāstrike your roof, they can bruise, crack, or even dislodge the protective granules that shield your shingles from UV rays and water intrusion.
Hail damage often doesnāt cause immediate leaks but compromises the integrity of your roof. Over time, water can seep in and cause rot, mold, or insulation damage.
š 1. Granule Loss
Granules are the small, sand-like particles that coat asphalt shingles. After a hailstorm, these granules can be knocked loose, leaving exposed black patches.
What to look for:
- Bald spots on shingles
- Granules accumulating in gutters or downspouts
- Dark, shiny areas on the roof surface
Why it matters: Without granules, your shingles are exposed to UV damage and deteriorate faster.
š 2. Circular Bruises or āDingsā
Hail often leaves behind soft, circular indentations or bruises where it struck. You may notice:
- Quarter- to golf ball-sized dark spots
- Spongy-feeling areas when pressed
- Slightly crushed or dented surfaces
Tip: Run your hand lightly over the shingle surface. Hail bruises can feel soft, even if theyāre not clearly visible from the ground.
š 3. Cracked or Split Shingles
Larger hail can cause the shingles to crack or fracture completely.
What to look for:
- Horizontal or diagonal cracks across the tabs
- Broken corners or edges
- Shingles that appear lifted or curled
Why it matters: Cracked shingles allow water to enter underneath, especially during Albertaās freeze-thaw cycles.
š 4. Impact Marks on Metal Components
Even if you can’t spot shingle damage, look at:
- Metal vents
- Flashing
- Roof caps or exhaust fans
If these show dents, your shingles likely took a hit tooāeven if the damage is more subtle.
š 5. Damaged Ridge Caps and Valleys
The ridge line and valleys of your roof are more exposed and often the first to show hail damage.
Check for:
- Crushed or dented ridge caps
- Granule loss along the center line
- Exposed fiberglass or backing material
šØ When to Call a Roofing Professional
If you suspect hail damage but arenāt sure, itās best to get a professional roof inspection, especially if:
- You live in a high-risk hail area (like southern Alberta)
- Youāve experienced hail larger than 1 inch
- Youāre considering filing an insurance claim
- You see signs of leaking, sagging, or interior water damage
Reputable roofers will document damage, provide a repair estimate, and help you file an accurate insurance claim.
š Bonus Tip: Donāt Delay Your Insurance Claim
Most home insurance policies in Alberta require you to report hail damage within 6 to 12 months of the storm. The longer you wait, the harder it is to prove the hail was the cause.
Take photos, get a roof inspection, and contact your insurance company as soon as possible after a hail event.
Final Thoughts
Hail damage on asphalt shingles doesnāt always look dramaticābut the consequences can be. From granule loss to hidden bruising, even minor impact can weaken your roofās long-term performance.
When in doubt, schedule a professional inspection. Catching hail damage early means fewer repairs, smoother insurance claims, and peace of mind for your homeās most important layer of protection.
