Granules... What are those?

When's the last time you looked at your roof?

Be honest.

We get it! It's an easy thing to overlook in our day-to-day life's.

But... If you look closely at an asphalt shingle roof, you may notice that there are small bits of what look like sand or rocks on the surface.

These are important for the Health of your home!

These small bits of the asphalt shingle are known as granules, and while they may seem insignificant at first glance, they play a vital role in the overall health and durability of your roof.

So, what exactly are these granules, and why are they so important? Let’s take a closer look.

Have you ever wondered what those gritty, colorful bits on your asphalt shingle roof are made of?

Those tiny granules are actually made of crushed natural stone, carefully selected for its specific physical properties. And that's not all - these granules undergo a special process involving ceramic firing to give them a longer-lasting hue in a range of different colors. But did you know that the granules on the visible part of the shingles serve another purpose, besides adding a splash of color?

One of the primary functions of these granules is to provide protection against the sun’s ultraviolet (UV) rays and extreme temperature changes.

The granules physically block and limit the amount of sunlight (and heat) that can be absorbed by the individual shingles, which helps reduce the chances of the shingles warping or curling.

But it’s not just about protection; granules also play an important role in the aesthetic appeal of your roof. Without the granules, asphalt shingles would have a plain, flat look. The granules, while still embedded in the shingles, create a distinct texture that enhances the overall look of the roof’s surface.

Yes...

Granule loss does happen

gradually as your roof is

exposed to wind, rain and hail

for many years.
