When you look at your roof, you probably notice that your asphalt shingles appear to be covered in small granules. This roofing material is actually very important to the structure of your roof and the protection of your home. So it’s important that you keep an eye on these granules and call for an inspection if you notice them wearing away or changing appearance. Here’s what you need to know about this important, but often overlooked, roofing material.

What Is the Purpose of Shingle Granules?

They Protect Your Roof From the Elements

Asphalt can wear away over time when exposed to UV rays, rain, wind, and other harsh weather. However, granules are made from stones that are naturally hard and resistant to these elements. It takes more than just shingles to protect your home; it takes an integrated system of components and layers designed to withstand the forces of nature outside while controlling temperature and humidity inside. Essentially, the granules provide an extra surface between the asphalt and the open air so that the asphalt shingle base remains supple, lasts longer, and is less likely to need serious repairs.

Asphalt Shingles Provide Aesthetic Value

The roofing material is best known for its aesthetic appeal. Granules can be manufactured in a variety of classic shades and can have the dimensional appearance of natural wood or slate to complement your home’s exterior. And, the varied shades of each tiny granule provide depth and interest to the overall surface of your roof.

Asphalt Shingles Make Your Home More Energy Efficient

Since many of the stones used in shingle granules have reflective surfaces, they’re able to better protect your home from absorbing the sun’s rays. By reflecting that heat, not only is your home cooler but your home’s HVAC system can run more efficiently, saving you money on those monthly energy bills.

Because granules play such an important role in the integrity of your roof system, it’s important to call for a roof inspection if you notice an issue with them, such as missing or broken shingles.
