Asphalt shingles usually consist of granules that provide an extra layer of protection for your roof. However, various weather elements can loosen these granules over time, while severe storms can cause them to dislodge or shed in significant amounts.
Top-rated roofing contractor ARCH Exteriors, LLC shares a few more details about asphalt roofing granules. We also offer some tips on determining when you should be concerned about your roof’s granules.
What Are Roofing Granules?
Asphalt roofing granules are typically rock-hard. And during the manufacturing process, they are crushed and screened to specific granular sizes. Natural stone color is also typically applied on granules that are placed on areas of the shingle that are not visible. Meanwhile, different colors are used on granules for the exposed areas so that they match the color of the shingles.
You can also opt to boost the features of your roofing granules so that discoloration due to blue-green algae can be prevented. Simply choose algae-resistant granules for your shingles if you want this specific type of protection. Apart from that, you can also increase the ability of your shingles to reflect the sun’s heat by selecting reflective asphalt roofing granules.
When Should I Be Concerned About My Roof’s Granules?
If your shingles are relatively new, there’s no need to worry if you notice some granules in your gutter or on the ground. It’s common for new shingles to shed the extra granules that they have. But if your roof is old or a storm recently occurred in your area, you might want to ask your roofer to take a closer look at your roofing granules.
Check your gutters and downspouts for excessive amounts of granule residue, and look for bald spots on your roofing. These signs typically indicate too much granule loss, which could compromise your roof system as it means reduced protection for your asphalt shingles.
