What are Asphalt Roofs Made Of? A Comprehensive Guide

Asphalt roofs are a popular choice for many homeowners due to their affordability and ease of installation. But what exactly are they made of? The composition of asphalt roofs may vary, but they generally consist of mineral fiber and cementitious fillers. Studies have revealed that asphalt represents only 5 to 35 percent of roof tiles. This material is also called ACM or “Asphalt-containing Material”.

Integrated roofing membranes are composed of layers of bitumen or cold-applied adhesive that serve as a weatherproof component of the membranes. Reinforcing piles, such as organic felt, fiberglass sheets and polyester sheets, are installed in each layer of bitumen or adhesive applied cold. Bituminous membranes are installed in multi-layer configurations with bitumen or adhesive applied cold between reinforcing layers, or layers of membranes, to build an “accumulated membrane”.Asphalt shingles are not made entirely of asphalt. Rather, they consist of a fiberglass base or felt paper coated with an impermeable layer of asphalt and covered with ceramic granules.

Since its development in the 1980s, the fiberglass base has been the most popular product. It is lighter and less expensive, but still provides considerable strength to the roof, as well as additional fire protection. The reason your roofer may have called them that is because an asphalt shingle is made of composite materials. The basic ingredient is asphalt, no doubt, but there are also more and more fiberglass blends in each layer. In fact, compared to older materials, today's modern asphalt roofing and asphalt coating materials have 40% less asphalt.

The overall composition varies depending on the manufacturer. An asphalt shingle is a type of wall or roof tile that uses asphalt for waterproofing. It is one of the most commonly used roof coverings in North America because it has a relatively inexpensive initial cost and is fairly easy to install. As long as the asphalt roof is properly installed and the attic is properly ventilated, it will come as close as possible to the lifespan specified by the manufacturer. However, if you are making a long-term choice for your home, look for other types of roofing materials, in particular metal, tiles and slate, which have a significantly longer lifespan. This component has a sealing strip and, when properly placed, is located at the top and lowest edge of the roofing system.

They are mainly used as subfloor for asphalt shingles, rolled roofs and other types of roofing materials. Luxury, premium or designer tiles are thicker and are designed to add more visual interest to your roof. They can last as long as roof tiles, so it's important to choose the ones that match the look and color of the shingles.

The Manufacturing Process

The manufacture of asphalt roofing products is a continuous process performed on a roofing machine that begins at one end with a roll of core material and ends at the other end with the finished product. They are typical components of new roof installations and repairs, and provide decent protection to your home at an excellent value for money. Starter strips, which are used to waterproof the edges of the eaves and rakes of the house during the replacement of a roof, are essential components for your new roof. Today there are many types of residential roofing materials on the market, but the most popular is the asphalt tile roof.

Roof Maintenance

To avoid costly repairs and premature roof failure, be sure to maintain the roof ventilation system regularly.

That's why it's absolutely crucial to keep your roof running smoothly throughout its lifespan with regular maintenance.

Types Of Asphalt Roofs

Dimensional or architectural tiles are thicker and stronger, vary in shape and size and offer greater aesthetic appeal; by casting more defined and random lines of shade, they better mimic the appearance of traditional roofing materials such as shaken wood tiles.
