Understanding the Role of Granules 

Granules are very tiny, but have a very big impact on the life and appearance of the roof.

In this video, Greg Malarkey, Senior VP of Malarkey Roofing Products, explains the importance of granules. Granules are something that everyone sees when they look at a roof and according to Greg, they have four functions that they need to perform.

1 – UV Ray Protection. Asphalt ages because of UV rays from the sun. Granules help protect the asphalt from those harmful rays.

2 – Appearance. The average shingle manufactured by Malarkey Roofing Products has six different granule colors. By combining colors, they are able to generate a wide palette of color choices to complement any home.

3 – Work surface safety. When a roof is being installed it’s important that the granules stay on the shingle, so the roof surface isn’t dangerous to the contractor. At Malarkey, a great deal of attention is paid to granule adhesion as a safety aspect.

4 – Manufacturing. In the manufacturing process, granules are the separation between the machines and the asphalt product that allows the shingles to be made.

So, while granules are a small item, they do indeed make a very big impact on the life and appearance of the roof.
