The Anatomy of a Shingle
Asphalt shingles are one of the most popular roofing options for homeowners. This is because asphalt shingles withstand a lot of weather elements, come in a variety of colors and are relatively long-lasting and affordable. However, while they are popular, many homeowners do not really understand the anatomy of a shingle or even realize that a shingle is made up of different layers, all of which help to increase the function of the shingle. Here is more information on the anatomy of a shingle.
The bottom layer of your asphalt shingle is referred to as matting. Matting is typically made of either cellulose for older shingles or fiberglass for new shingles. Fiberglass overtook cellulose for the matting material within the past two decades. Think of matting as the foundation for your shingle. If the foundation is strong and durable, it can withstand the weight of the additional layers of the shingle. It is also able to support the shingle as the wind blows it or the shingle shifts.
Asphalt is used for the middle layer on asphalt shingles. Most people associate asphalt with roads, driveways, or walkways, but that same black tarry substance can be used in a shingle to help repel water and prevent water from seeping through a roof. When it comes to asphalt shingles, the thickness of the asphalt is important to consider. Different shingles have different thicknesses for the layer of asphalt. A thicker asphalt shingle typically has a thicker middle core, which helps to keep water out and helps the shingle to last longer. However, the thicker the shingle is, the more expensive it typically is.
The final layer of a shingle is the granules. When you look at a shingle, the granules are what most people are looking at or see. The granules are typically made of sediment and have a rock or sand-like texture and appearance to them. The granules are added directly on top of the asphalt, helping to alter the shingle’s appearance. Granules are available in various colors and textures, which can ultimately help your roof add curb appeal and style to your home. However, the granules are not only used for aesthetic purposes. The granules help protect the asphalt layer from sunlight and heat, both of which can break asphalt down and shorten its lifespan.
Asphalt shingles are made up of different layers, each designed to help increase the strength of the shingle and helps to extend the longevity of the shingle.
