Understanding Tar Shingles A Comprehensive Overview

Tar shingles, also known as built-up roofing (BUR) systems, are a traditional roofing option that has stood the test of time. With a history dating back to the late 19th century, these roofing materials have evolved yet remain a popular choice for both residential and commercial buildings. Understanding tar shingles involves exploring their composition, benefits, installation process, and maintenance needs.

Composition of Tar Shingles

At their core, tar shingles are primarily made from layers of asphalt and roofing felt, which can be further reinforced with materials like fiberglass or organic felt. The construction typically involves alternating layers of asphalt, which provides a waterproof barrier, and felts, creating a durable surface. The final layer is often topped with gravel or a reflective coating to enhance durability and protect it from sunlight, thereby extending the lifespan of the roof.

Benefits of Tar Shingles

One of the key advantages of tar shingles is their excellent waterproofing ability. The multiple layers form a solid barrier against water intrusion, making BUR systems particularly effective in areas prone to heavy rainfall or snowfall. Additionally, these roofs are highly durable, with many installations lasting upwards of 20 years or more when properly maintained.

Tar shingles also offer versatility in terms of application. They can be used on both flat and low-sloped roofs, making them ideal for various building types. Furthermore, due to their heaviness, they can withstand strong winds better than lighter roofing materials. Tar shingles also provide an effective insulation layer, which can lead to energy savings over time.

Installation of Tar Shingles

Installing tar shingles is a specialized task that typically requires professional expertise. The process begins with the surface preparation of the roof, ensuring it is clean and dry. The first layer of roofing felt is applied, followed by hot asphalt, which acts as an adhesive for the subsequent layers. This layering process often requires several applications of asphalt and felt, with each layer being carefully installed to ensure optimal waterproofing.

A final layer is then applied, often consisting of gravel or a reflective coating. The gravel not only provides protection against UV rays but also improves the roof’s resistance to impact and wear. It's important to note that proper ventilation is crucial to prevent heat buildup and moisture accumulation, which can compromise the integrity of the roof.

Maintenance of Tar Shingles

Although tar roofs are known for their durability, they do require regular maintenance to extend their lifespan. This includes periodic inspections for signs of wear or damage, such as cracks or bubbling that could lead to leaks. Regularly cleaning the roof to remove debris, leaves, and dirt can also help prevent the buildup of moisture that can cause deterioration over time.

Additionally, addressing any issues promptly can prevent small problems from escalating into significant repairs. It's advisable to have a professional assessment of the roof every few years to ensure it remains in good condition and to make necessary repairs before they become more complicated.

Conclusion

In summary, tar shingles continue to be a reliable and practical roofing solution for many buildings. Their durable nature, combined with good waterproofing abilities and resistance to weather conditions, make them a favored choice among many homeowners and builders. However, like any roofing system, they require proper installation and regular maintenance to ensure they function effectively and contribute to the longevity of the structure they protect. By understanding the intricacies of tar shingles, homeowners can make informed decisions about roofing options that best suit their needs.
