When it comes to roofing, one of the most essential materials that often gets overlooked is roofing felt. Whether you’re in the midst of a new installation or looking to repair an existing roof, understanding what roofing felt is and its significance can make all the difference. In this article, I will delve into the various aspects of roofing felt, its benefits, types, and everything you need to know to make an informed decision.
What is roofing felt?
Roofing felt, sometimes referred to as tar paper or underlayment, is a thin layer of material that is placed between the roof deck and the shingles. This layer acts as a protective barrier against moisture and is crucial for the longevity of your roof. Made typically from fiberglass or organic materials, it is saturated with asphalt to enhance its waterproofing properties. It plays a vital role in safeguarding not just the roof but also the entire structure of your home.
Why is roofing felt important?
The importance of roofing felt cannot be overstated. It serves multiple purposes that contribute to the overall health of your roofing system:
- Moisture Protection: One of the primary functions of roofing felt is to act as a moisture barrier. It prevents water from seeping through to the roof deck, which can cause wood rot and other damages.
- Temperature Regulation: Roofing felt helps to insulate your roof, maintaining a more stable temperature within your home. This can lead to energy savings in the long run.
- Wind Resistance: During storms, strong winds can lift shingles, exposing the roof to potential leaks. Roofing felt provides an additional layer of security against such weather conditions.
- Improved Roof Lifespan: By keeping moisture at bay and protecting the underlying structure, roofing felt can significantly extend the lifespan of your roofing materials.
Types of roofing felt
Understanding the different types of roofing felt available can help you make a more informed choice for your roofing project. The two primary types are:
Organic roofing felt
Organic roofing felt is made from recycled paper products that are saturated with asphalt. This type of felt is quite flexible and easier to work with, making it a popular choice among contractors. However, it is also more susceptible to moisture over time, which can lead to mold issues if not properly installed.
Fiberglass roofing felt
On the other hand, fiberglass roofing felt is made from a mat of fiberglass strands that are also saturated with asphalt. This type is known for its durability and moisture resistance, making it a preferred option for many homeowners. Although it might be a bit more challenging to handle during installation, the long-term benefits outweigh the initial difficulties.
Installation tips for roofing felt
If you’re considering installing roofing felt, here are some practical tips to ensure it is done correctly:
- Start with a clean surface: Before applying roofing felt, ensure the roof deck is clean and free of debris. This allows for better adhesion and prevents any moisture from being trapped underneath.
- Overlap the seams: When laying down the felt, be sure to overlap the seams by at least 6 inches. This ensures that water will run off the roof rather than pooling in between seams.
- Use proper fasteners: Use roofing nails or staples specifically designed for roofing felt. They should be long enough to penetrate through the felt and into the deck securely.
- Secure the edges: Make sure to secure all edges properly to avoid any lifting during windy conditions. This can be done by using additional fasteners along the perimeter.
Maintenance of roofing felt
Once the roofing felt is installed, maintenance is crucial for ensuring its effectiveness over time. Here are some maintenance tips:
- Regular inspections: Conduct routine inspections of your roof to identify any potential issues early. Look for signs of wear or damage to the felt, especially after severe weather.
- Clear debris: Keep the roof surface clear of leaves, branches, and other debris to allow for proper drainage and prevent moisture buildup.
- Address leaks promptly: If you notice any leaks in your roof, address them immediately. Ignoring leaks can lead to significant damage, making repairs more costly.
Frequently Asked Questions
How long does roofing felt last?
Typically, roofing felt can last anywhere from 10 to 20 years, depending on the quality of the material and the environmental conditions. Regular maintenance can significantly extend its lifespan.

While it is possible to install roofing felt yourself, it is highly recommended to hire a professional for the best results. Proper installation is key to ensuring that the felt performs its intended function.
Is roofing felt necessary under shingles?
Yes, roofing felt is necessary under shingles as it provides an essential moisture barrier. Skipping this step can lead to serious issues, including leaks and structural damage.
What are the costs associated with roofing felt installation?
The cost of roofing felt installation can vary based on the size of your roof, the type of felt used, and labor costs. On average, homeowners can expect to spend between $0.50 and $1.50 per square foot.
In summary, understanding the role of roofing felt is essential for any homeowner or contractor involved in roofing projects. With its moisture protection, temperature regulation, and longevity benefits, it plays a pivotal role in maintaining the integrity of your roof. Whether you are installing a new roof or repairing an existing one, investing in quality roofing felt is a decision that will pay off in the long run.
