Aging Shingles Losing Granules? Time To Have Roof Checked

by | Apr 12, 2018

Does Your Roof Have Aging Shingles?

One of the most common questions we receive from customers is about aging shingles. As spring approaches and snow melts off, homeowners see granules coming off in the gutters and they wonder why that is. In today’s post, our team of experts discuss aging shingles, what can cause they and how it affects your home.

First Signs:

Gutter Granules

The very first sign of aging shingles is that you will start seeing granules in your gutter lines after heavy rainfalls. Water basically runs over the shingles taking the granules from the shingles with it. These granules start gathering in your gutters visible to naked eye. It’s completely normal to lose some of the granular textures on the roof. Over time however aging shingles starts to become a concern.

What Are Those Granules Anyway?

Question Mark

Asphalt shingles are one of the most widely used type of shingles on roofs because they’ve been around for a while. Their design has been perfected by many manufacturers in the industry over time. One of the ways manufacturers have made shingles more sturdy and protective of a home is by adding granules onto the exterior. This helps fight the natural elements. Aging shingles lose granules giving a definitive answer to the question of whether it is time to repair or replace your roof.

Why Are Granules On Shingles?


Granules were added to the design of shingles because of mainly these reasons:

  1. They help keep ultraviolet rays off the shingle’s asphalt coating. UV rays can cause a lot of damage. Aging shingles lose granules hence becoming more prone to damage to the home.
  2. They protect from algae, fungus and moss from growing in-between shingles and crevices.
  3. Adding granules helps make the shingles more fire-resistant.

#1 Reason For Loss of Granules:



Our team of experts here at American Standard Roofing advise that heavy rain or strong wind are number 1 reasons that make your roof lose granules. If after a storm, you find a buildup of shingle granules in your gutters or on the ground, don’t panic. Homeowners should check for granules on aging shingles. If granules are gone, a roof repair and shingle replacement should be considered. A small amount or no granules can be bad news for your roof. Our team advises inspecting roof and specifically shingles in a timely manner.
