The top layer of asphalt shingle consists of tiny pieces of stone and rock, best known as shingle granules. These give your shingle color and an extra level of protection against the sun. But unfortunately, the harsh weather can take a toll on these granules.
Granular loss, therefore, becomes a common concern as shingles start to age. While minor granule wear is normal over time, significant or premature loss can lead to more serious issues if it’s not treated on time.
When there is too much granular loss on the roof, homeowners often wonder about their repair options. Is a roof replacement the only option or can you repair granular loss on a roof yourself? Understanding the extent of granular loss and its underlying causes can help you determine your next steps.
Why Should You Be Concerned About Granule Loss?
Over time, some granule shedding is normal, especially after heavy rain or wind. However, excessive granular loss can expose the asphalt layer underneath, leading to problems such as:
- Increased vulnerability to UV damage
- Accelerated wear and tear
- Water infiltration risks
If you’ve noticed excessive granules in your gutters or around your home’s downspouts, it’s time to take action.
How To Inspect for Granular Loss
Before even contemplating the choice to make repairs, it’s important to assess the extent of the damage. Here’s how to conduct a thorough inspection:
- Check Your Gutters: Look for a large accumulation of granules in your gutters or at the base of your downspouts. Finding some granules is normal, but a heavy buildup signals a problem.
- Visual Roof Inspection: From the ground, inspect your roof for bald spots, discoloration, or uneven patches. If it’s safe to do so, use a ladder to get a closer look.
- Examine Shingles Up Close: Gently run your hand over the shingles. If granules come off easily, the shingles may be deteriorating.
- Inspect After Severe Weather: After a hailstorm or strong winds, check your roof for new signs of damage.
If you’re unsure about the condition of your roof, consider hiring a professional roofing company for a detailed inspection.
How To Repair Granular Loss On A Roof: What You Need To Know
Once you notice the presence of bald patches on your shingles and notice they’re constantly losing granules, it is time for damage control. But here’s the hard truth: once shingle granules have fallen off, they cannot be reattached or restored. These protective mineral granules are permanently embedded during the shingle manufacturing process and will not provide the level of protection you need if you attempt to add granules yourself.
Luckily, there are some ways to handle the situation:
Clean the Affected Area
Proper preparation is the first step in any roof repair. Remove loose debris using a soft-bristled broom or low-pressure leaf blower. This gentle approach prevents additional granule loss that can occur with aggressive cleaning methods. Take care to clean carefully, avoiding any additional damage to the already compromised shingles.
Apply Roofing Sealant
Roofing sealant serves as a critical barrier to protect exposed areas:
- Clean the damaged shingle thoroughly
- Apply a thin, even layer of roofing sealant
- Gently press down to ensure proper adhesion
- Use only sealants specifically designed for roofing application
Reinforce Edges
For shingles that are starting to lift at the edges, use additional roofing adhesive to secure them. Apply a small amount under the shingle edge, press it down, and hold it in place for a few seconds. This prevents further damage from wind or water infiltration.
Monitor the Repairs
After completing the repairs, periodically inspect the area to ensure the solution is holding up. Keep an eye on the rest of the shingles and check for any signs of additional wear.
Note: If the granule loss is excessive, it is time to consider replacing the shingles.
