Built-up roofing is the most popular material used on low-slope roofs. These systems are used on both commercial and residential structures here in Arizona, and as your premier roofing contractor in Arizona, RENCO Roofing is here to educate you about built-up roofing systems. To start off, a built-up roofing system is composed of several layers of bitumen surfaces and finished up with an aggregate layer or coating.

Some built-up products include a durable insulation layer as part of the built-up roofing. Insulation is more widely used in the colder parts of Arizona, in order to help with insulation. The fabrics or layers used on built-up roofing are also known as ply sheets. These sheets are typically reinforced with fiberglass or organic mats, depending on the roof. A lot of the time, built-up-roof systems fall under many different variations or names, such as: tar and gravel, modified bitumen, and rolled roofing.

Layers of Built-Up Roofing Systems
Built-up roofing systems are most commonly applied with three or four layers of roofing materials to make up the complete roofing system. These layers are typically a base sheet, a fiber sheet, and then either one or two layers of bitumen.

When you get a built-up roofing system installed on your home, our expert contractors will first mechanically fasten the base sheet to the structure with screws and washers. Then, the fiber sheet will be applied on top of the base sheet. Finally, the layers of bitumen can be applied in different methods. The most common of these are cold-applied adhesive, hot tar, and torch-down. Sometimes, you’ll also find granule or aggregate surface of gravel or minerals applied over the top.

Types of Built-Up Roofing Systems
When you decide to install a new built-up roofing system, you’ll have your choice of several different roofing alternatives. A couple of the most popular types are the smooth asphalt built-up and ballasted asphalt built-up. The bitumen materials in these types of built-up roofs are asphalt, coal tar, or cold-applied adhesive. Ballasted asphalt is more popular than ever before due to the fact that it can provide an excellent finish surface its material works great as a fire retardant agent.

Another popular type of built-up roofing is cold built-up roofing. The advantages of this type of roofing are that it doesn’t have toxic fumes when applied, it is better for environmentally sensitive projects, and it’s not dependent on weather.
