What is Roofing Felt?

Roofing felt, also known as tar paper, is a type of underlayment used in the construction industry to provide an extra layer of protection between the roof deck and the shingles. It is typically made from a combination of cellulose, polyester, bitumen, and asphalt. Roofing felt comes in rolls and is installed in overlapping layers to create a waterproof barrier.

Benefits of Roofing Felt

One of the main benefits of using roofing felt is that it helps to prevent water from seeping into the roof deck, which can cause damage to the structure of the building. Additionally, roofing felt can help to improve the overall energy efficiency of a building by providing an extra layer of insulation.

Types of Roofing Felt

There are several different types of roofing felt available on the market, including organic felt, fiberglass felt, and self-adhesive felt. Organic felt is made from recycled materials and is biodegradable, while fiberglass felt is more durable and resistant to tearing. Self-adhesive felt has a sticky backing that makes installation easier.

Installation Process

To install roofing felt, start by laying the first layer at the bottom of the roof and working your way up. Overlap each layer by a few inches to ensure a watertight seal. Use a hammer tacker or roofing nails to secure the felt in place. Trim any excess felt with a utility knife.

Maintenance and Repair

Regular maintenance of your roofing felt is essential to ensure its longevity. Inspect the felt for any tears or damage, and replace any damaged sections as needed. It is also important to keep the roof clean and free of debris to prevent water from pooling and causing leaks.

Cost of Roofing Felt

The cost of roofing felt can vary depending on the type and quality of the material. On average, homeowners can expect to pay between $0.50 to $1.00 per square foot for roofing felt installation. It is important to factor in the cost of labor and additional materials when budgeting for a roofing project.

Common Issues with Roofing Felt

Some common issues that can arise with roofing felt include wrinkling, buckling, and moisture damage. These issues can be caused by improper installation, poor ventilation, or extreme weather conditions. It is important to address any issues with your roofing felt promptly to prevent further damage.

Conclusion

Roofing felt is an essential component of any roofing system, providing an extra layer of protection and insulation. By understanding the benefits, types, installation process, and maintenance requirements of roofing felt, homeowners can ensure the longevity and durability of their roof.
