A roofing material composed of asphalt-saturated and coated felt or fiberglass, manufactured in long rolls, is a common low-slope roofing solution. This product is typically installed in overlapping courses, sealed with roofing cement or a torch-applied adhesive, to create a waterproof barrier. Its application is frequently seen on outbuildings, sheds, and other utilitarian structures.
The utilization of this material offers several advantages, including relative ease of installation and cost-effectiveness compared to some alternative roofing options. Historically, its development and use have been driven by the need for an affordable and quickly deployable weatherproofing solution, particularly for large or low-incline surfaces. The longevity and performance characteristics can vary depending on the quality of the material and the expertise of the installation.
The subsequent sections will delve into the specific types available, the recommended installation practices, and the considerations for maintenance and repair to ensure optimal performance and lifespan. Further discussion will explore potential drawbacks and suitable alternatives for different roofing needs.
1. Asphalt-based Composition
The asphalt-based composition is fundamental to this type of roofing, directly influencing its properties and applications. The asphalt acts as the primary waterproofing agent, preventing water penetration into the underlying structure. The saturation and coating of the felt or fiberglass mat with asphalt creates a flexible, albeit relatively thin, barrier against the elements. The specific grade and formulation of the asphalt determine the product’s resistance to UV degradation, temperature fluctuations, and physical wear. For instance, higher-grade asphalt compounds will generally exhibit greater longevity and reduced cracking, particularly in climates with extreme temperature variations. Without the asphalt component, the underlying felt or fiberglass would be susceptible to rapid degradation and offer negligible protection from moisture.
The choice of asphalt also impacts the installation methods. Some products utilize a cold-applied adhesive backing, while others require heat welding using a torch, techniques that rely on the asphalt’s ability to melt and create a strong bond. Furthermore, the granular surfacing embedded in the asphalt provides protection from ultraviolet rays, extends the lifespan, and adds a degree of fire resistance. Inferior or improperly applied surfacing will result in accelerated asphalt degradation and a shortened service life. Consider, for example, two identical outbuildings, one roofed with a high-quality, granular-surfaced option and the other with a product lacking adequate surfacing. The latter will likely require replacement significantly sooner due to asphalt embrittlement and subsequent cracking.
In conclusion, the asphalt-based composition is not merely a component but rather the defining characteristic of this type of roofing. Its properties, quality, and application directly correlate to the performance, longevity, and overall suitability of the material. Understanding the nuances of the asphalt component is therefore critical for informed material selection and installation practices, ensuring a cost-effective and durable roofing solution where appropriate.
