Asphalt roofing granules - what you need to know

There are many different types of roofing materials to choose from, whether it be concrete tiles, terracotta, steel materials like Zincalume and Colorbond, or asphalt roofing. It's important to know as much information as possible about your roofing materials to ensure they are getting the best care. 

Today we're going to talk a little bit about granules, something that everyone notices when they look at a roof but no one really comments on until they need replacing. Granules on Asphalt roofing shingles have 4 distinct functions that they need to perform in order to protect your roof from the elements and keep your home in tip-top shape. Those four roles include:


Protect the roof from the harmful UV rays of the sun. By putting granules on the roof shingles you are effectively putting a layer of sunblock between the roof and the sun and therefore extending the life and durability of the roof.

Appearance. Granules on Asphalt roofing shingles play an important role in the appearance and giving you a nice finished look.

Creating a safe work surface. Have you ever been up onto a roof on a rainy day? if you have, you'll know just how important granules on Asphalt roofing shingles can be.

They are essential during the manufacturing process. Asphalt roofing shingles require a layer to protect them from the machining when they are being manufactured. Granules provide that layer and allow asphalt roofing shingles to be produced on a larger scale.
