Granules. They sound like something you’d find in a box of granola or the bottom of a fish tank, but granules are the unsung heroes for your roof shingles. They’re like the SPF 50 sunscreen for your home—protecting your roof from UV rays, hail, and Colorado’s famously unpredictable weather.

So, when you spot what looks like a roof shingle exfoliation party happening in your gutters or driveway coming from your downspouts — tiny, gritty specks where they shouldn’t be—you might wonder:

“Is granule loss normal? Or should I start Googling ‘best roofers near me’ and panic-eating Goldfish crackers?”

Fear not. Denny’s Roofing (your friendly, local Colorado roofing company!) is here to explain granule loss, what it means, and when to be concerned.

Let’s dig in (pun intended).

🚫 First, What ARE Granules?

Let’s get nerdy for a second. Granules are the rough, sandpaper-like bits on your asphalt shingles. They’re typically made of crushed stone, ceramic, or minerals and are embedded into the top layer of your shingles to do some essential things:

• Protect against UV rays (sunburned roofs? Consider a roof replacement if you notice significant granular loss.)
• Add fire resistance (because lightning and grills happen)
• Provide color and curb appeal (aka make your roof look good)
• Protect the underlayment of your roof from extreme weather.
• Add extra weight to help shingles stay in place and prevent granular loss.

In short: Granules are not just decorative rooftop sprinkles. They’re mission-critical.

🧐 Is Granule Loss Normal?

In a word: yes—but only to a point.

Here’s the thing: all asphalt shingles shed granules, especially in the first year after installation. This is like when your new car loses that “new car smell” or your dog sheds fur for the first time, similar to how your asphalt roof may show signs of wear over time. It’s just part of the process.

Normal granule loss might happen due to:

• Weathering can cause granular loss on your roof, leading to potential leaks. – Rain, wind, and UV rays do a number over time.
• Age – Older shingles naturally lose granules as the binding materials break down.
• Installation shake-off – Some granules don’t stick well and will come off shortly after a new roof install.
• Gutter cleaning or roof raking – Aggressive brushing or scraping can and will speed up granule loss.

(Note: Use a blower, not a rake, to avoid damaging your asphalt shingle roof.)

But (and this is important)… excessive granule loss can be a red flag.

⚠️ When Granule Loss = Danger

Here’s when you should start dialing your local roofer faster than you can say “Hailstorm 2023”:

1. Bald Spots and granular loss can indicate issues with your roofing materials.

If your shingles are missing patches of granules and you see black, shiny, or exposed spots, that’s not a trendy new roof design. The fiberglass or asphalt layer shows significant vulnerability, especially to hailstones.

2. Clogged gutters full of grit can lead to issues such as hail damage on your roofing materials.

Sure, a few granules in your gutters is no biggie. But if your downspouts look like they’ve been hauling buckets of coarse sand? That’s a sign of accelerated wear.

3. Shingles Are Curling or Cracking

Granule loss combined with shingle curling or cracking is like when your favorite jeans get a hole and lose a button. It’s time to let go and upgrade.

4. Your Roof is 20+ Years Old

Shingles wear out. If your roof has been around since the days of Blockbuster and MySpace, it’s probably due for an inspection—or even a replacement.

🏔️ Colorado Weather = Granule Kryptonite

Let’s talk local. In Colorado, our roofs deal with a lot:

• Hailstorms that sound like drum solos on your roof
• High-altitude UV rays that hit harder than a Colorado IPA
• Snow that sticks around longer than your in-laws during the holidays
• High winds that treat shingles like Frisbees

All these environmental stressors lead to accelerated granule loss. That’s why Colorado homeowners need to be extra roof-savvy—and have a go-to roofing company (spoiler alert: it’s us 🙋‍♂️) on speed dial.

👷‍♂️ What Should You Do If You Notice Granule Loss?

• Don’t panic, but do pay attention.
• A few granules = fine. Shingles shedding like your golden retriever? Not so much.
• Schedule a free inspection with a professional roofer. Denny’s Roofing offers free roof inspections across the Front Range – We’ll check for loose granules and other signs of wear on your roof.
  • Shingle integrity
  • Granule coverage
  • Signs of hail or storm damage
  • Underlayment condition (the stuff underneath your shingles)
• Document everything.
• Suppose the granule loss appears storm-related, snap pics! You might qualify for insurance-covered roof repair or replacement; documentation is key.
• Avoid climbing the roof yourself. Leave the ladder gymnastics to the pros unless you moonlight as a mountain goat. Seriously—it’s not worth the risk. (We’re insured. You’re not.)

🛠️ Repair or Replace?

Granule loss can sometimes be repaired, especially if caught early. But if it’s widespread or your asphalt shingle roof is aging out of its warranty, it might be more cost-effective (and safer) to consider a roof replacement.

We’ll explain both options, answer your questions, and never pressure you. Denny’s Roofing believes in honest roofing for real people.

Other Related Questions We Received Related to the Roofing System of Older Roofs

Q: What is shingle granule loss, and should I be worried about it?

A: Shingle granule loss refers to the shedding of the mineral granules from the surface of asphalt roof shingles. While some loss is normal as the roof ages, significant granule loss can indicate underlying issues such as storm damage or a manufacturing defect, which may require attention from a roofing professional.

Q: How can I identify granular loss on my asphalt shingle roof?

A: Granular loss can be identified by checking for loose granules in your gutters or the ground around your home. Additionally, inspecting the roof surface for bare spots where the mineral granules have dislodged can help identify areas of concern.

Q: What causes granule loss on roof shingles?

A: Granule loss can be caused by aging, storm damage, poor roof maintenance, and manufacturing defects. New asphalt shingles may also shed excess granules initially, which is typically not a cause for concern.

Q: Is asphalt shingle granule loss a sign that I need a roof replacement?

A: Not necessarily. While some granule loss is normal, a roofing professional should assess the extent of the loss. If a significant amount of granules are missing across the whole roof, it might indicate the need for a roof replacement to prevent further deterioration of your roof.

Q: How does roof slope affect granule loss?

A: Roof slope can influence the rate of granule loss. Steeper slopes may experience more granule shedding due to increased water runoff, which can dislodge granules more easily than flatter roofs.

Q: Can regular roof maintenance help prevent premature granule loss?

A: Yes, regular roof maintenance can help extend the longevity of your roof by identifying and addressing issues early on, reducing the risk of premature granule loss and other damage shingles might suffer over time.

Q: Are there any specific signs of a manufacturing defect causing granule loss?

A: A manufacturing defect may cause uneven granule loss or patterns of missing granules that are not typical of normal wear and tear. If you suspect a defect, it is advisable to have a roofing professional inspect your roof covering.

Q: How does storm damage contribute to the loss of granules?

A: Storm damage can significantly impact the amount of granule loss by causing shingles to lift or tear, making them more susceptible to damage and dislodging granules from the roof surface.

Q: What is the role of roofing granules on asphalt shingles?

A: Roofing granules protect the asphalt shingles from ultraviolet rays, add color and aesthetic appeal, and provide an additional layer of durability. Loss of these granules can lead to a deterioration of your roof’s protective capabilities.

Final Thoughts: Don’t Brush Off the Granules

Granule loss might seem minor, but it’s often a symptom of bigger roof health issues. Think of it like a cough that won’t go away—it could just be allergies… or it could be time to check things out.
