Golf-ball-sized hail reported during the recent storm that affected many Winnipeg-area homeowners.

Many homeowners were concerned about potential roof damage after this storm. One of our customers contacted us after returning from vacation to share what they found when they inspected their roof

Recent hailstorms across Winnipeg have left many homeowners wondering the same thing:

"Did my roof survive the storm?"

While hail can cause significant damage to asphalt shingles, not every roof responds the same way. Factors such as the age of the roof, the condition of the shingles, and previous maintenance can all play a role in how well a roof withstands severe weather.

Recently, one of our customers contacted us after returning from an Alaskan cruise shortly after a major hailstorm moved through the area.

They told us they were concerned they might be coming home to a damaged roof.

In their words:

"My Mazda took a pounding in the driveway unfortunately. I went on the roof to check for damage. As far as I could tell I only lost some pebbling from the shingles. No holes or broken shingles. So I'm going to say the Nano Tech product definitely helped limit any damage or deterioration to the fiberglass shingles."

While every roof and every storm are different, this homeowner's experience highlights the importance of maintaining and inspecting your roof before problems develop.

Common Signs of Hail Damage on Asphalt Shingles

After a hailstorm, homeowners should look for:

  • Excessive granule loss
  • Dark spots where granules have been knocked away
  • Cracked shingles
  • Broken shingle tabs
  • Exposed fiberglass matting
  • Damaged roof vents, flashing, or metal components
  • Debris collecting in eavestroughs

Some hail damage is obvious, while other damage can be difficult to identify without a closer inspection.

Why Granule Loss Matters

The protective granules on asphalt shingles help shield the roof from ultraviolet rays, weather exposure, and premature aging.

When hail impacts a roof, some granule loss can occur. Minor granule loss does not necessarily mean a roof has failed, but significant loss may shorten the lifespan of the shingles and leave them more vulnerable to future deterioration.

That is why it is important to inspect a roof after severe weather, even when there are no visible leaks.

The Importance of Roof Flexibility

As asphalt shingles age, they naturally become more brittle.

Brittle shingles are generally more susceptible to cracking, splitting, and damage from wind, hail, and freeze-thaw cycles.

Roof rejuvenation treatments are designed to restore flexibility to aging asphalt shingles and help reduce the effects of long-term weather exposure. Learn more about our shingle rejuvenation service.

While no treatment can guarantee protection from severe hail, maintaining flexible, healthy shingles may help a roof better withstand everyday environmental stresses. Want to understand the science behind shingle flexibility and roof preservation? Visit our See the Science page.
