What Does Hail Damage Do to a Roof?

Living in Calgary, no one is surprised to have hail at any time of the year! We’ve seen it all when it comes to the weather this area of Canada can have. Without warning our green lawns into an instant ice-ball winter wonderland. What happens when we think about in terms of damage? To our cars? Our roofs?

The effects of hail roof damage can differ according to a range of factors: hail size, wind speed, wind direction, the material of the roof, age of materials and slope all have an effect on the possible roof damage that occurs during a hail storm. Hail damage is bad for a roof when it leads to roof leaks and other issues.

Damage can be functional or cosmetic, and it’s the cosmetic damage that is sometimes more severe than it looks. Things like broken edges, bruises, punctures and granule loss can cause serious complications, though they may seem cosmetic at first.

To dive a little more into how hail damage affects a roof, let’s look at some specific types of damage:

Ask About Our 50-year Industry Leading Warranty Program.

Granule loss

Granules are the sandpaper-like part of the shingle. When a shingle loses granules, its asphalt coating is exposed to the elements, and this leads to accelerated aging. Take a look in your gutters and downspouts after a hailstorm to see if any granules have come off your shingles.

Exposed fiberglass mat

Hail impact on a roof can shatter the shingles’ surfacing, causing it to break away from the fiberglass mat underneath.

Weakened self-seal strip

High winds and hail can weaken the seal integrity of your shingles. A weakened seal is what causes a shingle to blow off and can leave your roof exposed to the elements. Once a shingle is damaged, its integrity has been permanently compromised. This can lead to leaks, and it can cause other shingles around it to tear.

Cracks in the shingles

Hard hail impacts or high winds can grip the shingles and cause cracks. This can lead to exposure and tears, leaving your roof with bare spots. Cracked shingles cannot effectively protect your roof from the weather.

Fractured fiberglass mat

Fractured fiberglass can be slightly harder to detect and usually requires a trained eye. Fractured fiberglass mats can result in tears and cracks from a point of hail impact.

Once you know about these common forms of hail roof damage, you can start to look for signs of damage on your property after a hailstorm.

How do you know if your roof or exterior has hail damage?

Severe roof damage, like shingles ripped off the roof or tree branches down, is obvious, but minor damage may be difficult to detect with an untrained eye. Get a roof inspection for a trained professional at BOSS to assess the hail damage on your roof or follow our helpful tips.

The first place to look for damage caused by hail is your gutters. High-impact hail that causes roof damage will most likely dent your gutters and/or downspouts. This is the easiest place to see and evaluate when looking for signs of roof damage. If there are dents and dings on your gutters and downspouts, you’re likely to have problems on the roof.

Gutters will also fill up and clog due to granules that shingles can shed when hail hits them. Clogged and overflowing gutters indicate that hail may have damaged your roof.

The second place we suggest looking is your siding, and the third place is your deck. Both of these areas will experience damage from a bad hailstorm and are easy indicators for potential shingle damage. Any hail damage on our siding or deck means you should get a roof inspection. BOSS Complete Renovations offers inspections to house siding and decks so if you are asking for a hail damage inspection, we look at all of these areas for you.

Can 1 inch hail cause damage to a roof?

Yes! In fact, even hail smaller than 1 inch can cause damage to a roof or to other areas of your house. After a hailstorm, the size of the hail can be the easiest indicator as to what types of damage you may face. While not a foolproof method for predicting storm damage, understanding the various sizes of hail and how they affect your home is a great place to start.

¾” Hail

Though the smallest hail we measure, ¾” hail can still be damaging depending on accompanying wind speeds. Hail this size typically damages vinyl siding, window screens, metal fascia and paint on a deck. We also see it dislodge granules from asphalt shingles and damage gutters and downspouts. Because of its smaller size, property owners often fail to identify the damages associated with hail under one inch.

1” Hail

Once we hit the 1” mark, we start to see bruising to shingle underlayment and significant damage to siding, gutters and fascia. Wind speeds will determine the severity of damage, and you will also see roof damage similar to damage caused by smaller sizes of hail.

1¼” Hail

With only a ¼” increase, the severity of this size of hail is much more significant. Parts of your property exposed to hail have the potential to look like swiss cheese. Even without wind, we’ll see this hail cause damage by simply falling out of the sky.

1½” Hail

This size of hail causes significant damage to property. Depending on the amount of hail, the length of time it falls and the accompanying wind speeds, damage to your property could be severe.

1¾ - 2” Hail

Now we’re getting to the size where the hail can penetrate softer parts of a roof, such as ridge caps or plastic roof vents. Combined with wind, this size of hail can tear siding completely off of a house, crack windows and damage most types of metal fixtures.

2” Hail

Anything this size or above will cause significant and severe damage to your property. We are no longer asking “if” you have property damage, but “where” you have property damage. It’s suggested that you call BOSS Complete Renovations immediately after this type of storm event.

What does roof damage from hail look like?

If a storm brings hail that is over one inch in diameter, the hail damage to your roof will probably be obvious. When hail is combined with high wind speeds, roof damage can be even more severe. It’s likely that you will be able to see signs of damage such as cracked or broken windows, damaged siding or dented gutters. Smaller hail can cause unseen damage to your roof, so make sure you contact a storm damage repair team at BOSS to inspect your roof after a hailstorm – no matter how small the hail was.
