If you’ve ever wondered what are roof shingles made of, you’re not alone. The material that shingles are made of is a complicated mix of several different components. Fiberglass, Asphaltic adhesives, stone granules, and asphalt are just a few of them. But they all serve an important purpose. Let’s take a closer look at what makes them so durable. We’ll also discuss their main features.


Roofing shingles are made of asphalt and are available in many varieties. There are jet shingles, art-loc shingles, and signature-cut shingles. Architectural shingles are made up of several layers of asphalt and are designed to resist water and avoid repetitive patterns. Standard three-tab shingles are used for hip and ridge lines. Roofing shingles need starter shingles and a base mat to be installed properly. The starter row is used to reinforce the shingles.

Shingles are held together by a thermally-activated asphalt sealant. These adhesives are applied to the top and bottom surfaces of the shingles during the manufacturing process. The shingles are then adhered together by the laminant to prevent them from separating during installation. Asphaltic shingles are very durable because of the adhesive that holds them together during the rigorous shingle and laminant installation process.

Despite their durability, asphalt shingles do not have the best water and wind resistance of all roofing materials. Metal roofing is a more durable option. Fortunately, asphalt shingles have undergone some improvements over the years. Today, they are widely available and come in a variety of styles. They are also recyclable and can even be used for paving. The most common material used for roofing in the U.S. is asphalt.

Organic shingles are another option that is more affordable. These shingles are made with a base mat of organic materials and are soaked in asphalt to make them waterproof. The granules are then applied to the top surface, which gives them a class B fire rating. While organic shingles are the most economical option, fiberglass shingles are better fire resistant than their fiberglass counterparts. In addition to being more economical, fiberglass shingles are lighter than organic ones.


Fiberglass is a strong, lightweight material that’s ideal for roofing purposes. These shingles are easy to install and require little preparation. Some fiberglass shingles are treated with a chemical coating to help control algae growth. In addition, they are relatively cheap to purchase and install. If you’re looking to replace your roof, you might consider installing fiberglass shingles for the aesthetic value they provide. But, before you do this, you should know about a few things.

Fiberglass shingles are similar to asphalt shingles, but they’re lighter than organic mat-based shingles. Although they’re not as durable or appealing as organic shingles, they’re easy to install and have the same appearance. However, you should consider your budget when deciding between fiberglass and asphalt shingles. If you’re concerned about energy efficiency, you might want to consider installing Energy Star-rated shingles. They can lower your cooling bill during hot months.

These shingles are available in a wide variety of colors. While three-tab fiberglass shingles offer a flat and unadorned roof, dimensional and architectural shingles can feature several visible shades or hues for a richer look. Most contemporary residential roofing materials feature an extensive range of premium and standard colors. The colors commonly found in fiberglass shingles are gray, brown, red, and green. This means you can customize your shingle color to match your home’s interior decor.

If you live in an area that experiences extreme weather, fiberglass shingles can endure long periods of time. However, their lifespan can be affected by thermal splitting and age. It depends on how carefully you care for your roof and how well it’s installed. Another option for fiberglass shingles is to invest in laminated shingles. These shingles have two separate layers of fiberglass bonded together with a sealant. These shingles are heavier and cost more but have a longer lifespan.

Stone granules

What make stone granules suitable for shingles is their hardness and opaqueness. This is necessary because the stone shingles will be exposed to intense solar UV rays and must withstand weathering over time. Colored shingles will require the durability of stone granules. To make a good choice for a roofing granule, a manufacturer should perform color fixation tests to ensure that the pigmentation will adhere to the stone.

The granules protect the asphalt from harmful UV rays and debris that will reduce the shingle’s lifespan. They also enhance the aesthetic appeal of a home. Some granules contain copper-based biocide to prevent algae growth. Some are coated with a sealant during manufacturing. A roof that is protected by granules will last much longer than one without them.

The base rock in granules will determine how effectively they block UV rays. Darker stones are better at blocking UV rays than light-colored ones. However, the ceramic color coating in roofing granules does not prevent the passage of UV rays. This can lead to premature degradation of the asphalt coating. This is why 3M roofing granules are made to be UV-opportunity.

While asphalt shingles are the most commonly used roofing material in the United States, there are other types of granules you can use. Asphalt shingles are relatively cheap and easy to install. They come in many different colors and styles. They have granules that are similar to sandpaper. It is not recommended that you use asphalt shingles for your roof. If you do choose asphalt shingles, be sure to choose a high-quality roof granule roofing material.

Asphaltic adhesives

What are asphalt shingles made of? Asphalt shingles are composed of layers of varying thickness and weight. Asphalt is the main component, followed by fiberglass or organic felt as a secondary component. Organic felt mats are made from recycled waste and are reduced to a water-based pulp. They are then shaped into sheets, strips or rolls and bonded with asphalt. Fiberglass shingles are sturdier than asphalt, as they are made from finely chopped glass filaments and water.

Typically, roof adhesives are water-based or solvent-based. A typical self-adhesive compound contains 3% to 10% Styrene-butadiene-styrene modifiers, 0% to 5% isoprene, and 6% to 25% hydrocarbon tackifying resins. The remainder of the roof shingle is comprised of asphalt and other components.

Asphalt shingles have self-sealing strips of adhesive on the underside to prevent wind-uplift from damaging the shingles. Unfortunately, some amateur installers have had success peeling this release film off, believing that it would expose the shingle sealant required for adhesion. In reality, however, this isn’t the case. If the adhesive is properly applied on the roof, then the shingles will adhere to the roof with no further problems.

To create an asphalt shingle, a roll of fiberglass mat or organic felt is fed into a wet looping machine. The asphalt coats the fibers and creates a stable base for the rest of the materials. The shingles are then cut with a cutting tool. These shingles are then glued together with asphaltic adhesives. However, in the event of a severe storm, the roof will become inoperable.

Fiberglass-coated mineral granules

The coating of mineral granules on roof shingles determines the color of the shingle. Light-colored shingles retain cooler temperatures and last longer in hot weather. Asphalt shingles may lose granules to varying degrees depending on various conditions. Diagnosing the cause of granule loss will help you estimate the remaining life of the roof, as well as verify your insurance claims and warranty claims.

The top coat of the shingle is made of fiberglass-coated mineral granules. They protect the shingle from ultraviolet rays and increase its fire resistance. Granules containing copper are added to prevent algae growth. Roofing granules with this type of coating also have an anti-microbial effect that inhibits algae growth.

When you install a shingle, you need to remember that the body of the shingle is exposed to sunlight. If you live in a freezing climate, the shingle substrate will begin to absorb water. The freezing and thawing cycle will exacerbate small cracks. It is important to pay attention to these small details before deciding which shingle material is best for your home.

Among the various types of roof shingles, fiberglass composition shingles are the most commonly used on residential buildings. These shingles are lightweight and easy to install. In addition to absorbing moisture, they also protect the home from extreme weather conditions. While these shingles are generally 0.625″ or 0.75″, they also provide no-fuss installation. In addition, they can be installed with or without fasteners.

Stone granules are the most visible ingredient on asphalt shingles. These are fine particles that are processed to a precise granular size and then added to the surface of the shingle. This granule surfacing also helps prevent discoloration caused by algae. You can also find shingles with special reflective granules. These shingles will reflect sunlight better than a flat or uncoated roof.
