Roof Shingles Losing Granules? You May Need Repairs

Are Your Shingles Losing Granules? You May Need Roof Repair

If you’ve noticed your shingles losing granules—don’t panic. Granule loss is normal, and it’s not always an indicator that you need roof repair. On the other hand, it could be time for a new one.

The condition of your roof plays a huge role in the protection and safety of your family. A well-kept roof is essential to preventing leaks and other incidents from occurring.

You’ve likely heard the saying” keeping a roof over your head”. While that’s just another way of saying to make sure you have a place to call home, it’s also a literal term.

To learn whether your shingle granule loss is a sign that you need roof repair, keep reading the information below.

Common Causes of Roof Granule Loss

Roofing granules are comprised of minerals and crushed stones, and they come in a variety of colors, shapes, and sizes. As your roof ages, some roof granules become loose from the asphalt layer. However, this could happen for several reasons, such as:

Shingle Blisters

Roof granule loss is often caused by blisters, which are pimple-like bumps that form on the surface of the shingle. Not only is it unsightly, but it’s harmful to your roof.

Blisters are generally the first step towards granule loss on shingles. Once the top of the surface wears off, it creates small holes of missing granule. 

Foot Traffic

Walking on a roof loosens granules from their attachment to shingles. If there’s lots of traffic on the roof, it creates “bald spots” on the shingles. If too much walking happens on old shingles, it causes roof shedding and cracks.


Granule loss on shingles also happens because of the weather. Occurrences like sun exposure and snow cause them to lose their bendability when exposed to varying temperatures.

Also, roof shedding doesn’t occur because of one issue, and it affects the entire roof. Therefore, a new shingle can have just as much wear on it as an older one.

Hail Damage

Another huge reason for shingle granule loss is hail. Severe weather creates pits in the roof and creates a lot of damage. A roof that’s been battered by harsh weather has a shorter life span and requires replacement sooner than usual.

Faulty Products

Granules can sometimes fall off due to faulty shingles. If the product is defective, it’ll create premature bald patches. It also creates shingle substrate on the roof.

How to Check for Roof Granule Loss

One of the best places to examine roof granule loss is at the edge of the roof. However, you should only do this is if your roof is stable enough. If it is, get down on your hands and knees to take a look at the damage.

Check for holes, cracks, and bald spots. If you don’t notice any bald spots, then granule loss isn’t an issue.

Also, when granules start to come off, they’ll fall into the gutter with the water and pile up on the ground.

Is It Time for a New Roof?

Although granule loss isn’t a big deal some of the time, if you notice severe damage, it’s time to call in the professionals. Here are some other signs to look for:

1. Roof Age

We explained above that age plays a role in granule loss. However, most roofs last about 20-25 years, unless some harsh conditions cause premature aging

. But if your roof hasn’t been repaired for a couple of decades, a new roof is needed. You shouldn’t hold off on it.

2. Leaks

This one might seem like a no-brainer, but it’s important to discuss it. If you experience any leaks in your home, get your roof repaired.

Many people will try to maintain the damage themselves and use tarps and other tools to patch up the problem. However, this is a bad idea and it only makes the issue worse.

3. Missing Shingles

Shingles play a large role in ensuring that your home is protected from the weather. Without these important components on your roof, your house is open to exposure from outside elements. Get your roof repaired as soon as possible if you notice this sign.

4. Sagging Roof

A saggy, droopy roof is a disaster waiting to happen. When your roof is in this condition, repair is required stat! Not only that, but this kind of wear and tear is usually accompanied by rotting boards.

If there’s trapped moisture on the roof,  there’s likely lots of weak material holding the roof together.

5. Moss

Moss is another common problem with roofs. If you notice these little patches of green “grass”, that’s not good. It only grows in moist conditions, so if it’s on the roof, that’s a sign that there’s trapped moisture.

Not only that, but wet conditions also breeds mold and fungi, which can damage your roof as well.

6. Bulking Shingles

In order to properly protect your home, shingles must lay flat. But if they’re curled and buckling, that’s a sign that they’re past their life expectancy. It could also mean that the roof is defective and should be fixed immediately.

7. Roof Valleys

If the shingles in the “valley” area of your roof are falling apart, you need repair services. This is the most vital part of your roof.

It’s the area where rain and snow flow through to get to the gutter. If this part of the roof is damaged, it’s prone to leaks.
