Roof felt, often overlooked, is a crucial component of a robust roofing system. Essentially, it’s a waterproof underlayment that protects your roof from the elements. Placed beneath the shingles, tiles, or metal roofing, it serves as the first line of defense against water infiltration.

What is Roof Felt Made Of?

Traditionally, roof felt was made from tar and organic fibers, like jute or cotton. However, advancements in roofing technology have introduced synthetic options. Modern roof felt is frequently crafted from polyester or fiberglass, offering enhanced durability and resistance to moisture.

Types of Roof Felt

The roof felt market offers a variety of options to suit different roofing projects.

• Organic Felt: Made from recycled paper and saturated with bitumen, organic felt is still used but has limitations in terms of lifespan and water resistance.
• Glass Fiber Felt: This type is stronger and more durable than organic felt. It’s often preferred for steeper roofs and areas with heavy rainfall.
• Polyester Felt: Known for its flexibility and dimensional stability, polyester felt is a popular choice for various roofing applications.

The Importance of Roof Felt

Roof felt plays a pivotal role in safeguarding your home from water damage. It acts as a barrier, preventing rainwater from seeping through cracks or gaps in the roofing material. Additionally, it helps to protect the roof deck from the harsh effects of the sun’s ultraviolet rays.

Benefits of Using High-Quality Roof Felt

• Waterproofing: The primary function of roof felt is to prevent water intrusion. A high-quality felt will effectively repel moisture, safeguarding your home’s interior.
• Durability: A durable roof felt can withstand harsh weather conditions, including strong winds and heavy rain.
• Underlayment Protection: By providing an extra layer of protection, roof felt helps extend the lifespan of your shingles or other roofing materials.
• Ice Dam Prevention: In colder climates, roof felt can help prevent ice dams by creating a more consistent roof temperature.

Installing Roof Felt: A Step-by-Step Guide

Proper installation of roof felt is essential for its effectiveness. Here’s a general overview of the process:

1. Preparation: Ensure the roof deck is clean and free from debris. Repair any damaged areas before installation.
2. Underlayment Placement: Start at the bottom of the roof and lay the first layer of felt, overlapping the edges by several inches.
3. Securing the Felt: Use roofing nails or staples to secure the felt to the roof deck.
4. Additional Layers: Depending on the roof’s pitch and local building codes, you may need to install additional layers of felt.
5. Flashing: Install flashing around chimneys, vents, and other roof penetrations to prevent water leakage.

Tips for Roof Felt Installation

• Wear appropriate safety gear, including gloves and a hard hat.
• Work from bottom to top to prevent damage to the installed felt.
• Ensure proper overlap between felt layers for optimal protection.
• Consider using a roofing underlayment primer for better adhesion.

Common Roof Felt Problems and Solutions

While roof felt is designed to be durable, issues can arise over time.

• Leaks: If you notice water stains on your ceilings or walls, it could indicate a leak in the roof felt. Inspect the roof for damaged or missing areas and replace them as needed.
• Blistering: Blistering can occur due to trapped moisture or improper ventilation. Improve attic ventilation to address this issue.
• Deterioration: Over time, roof felt can deteriorate due to exposure to the elements. Regular inspections and timely replacements are crucial.

Maintaining Your Roof Felt

To prolong the life of your roof felt and ensure optimal performance, follow these maintenance tips:

• Regular Inspections: Conduct visual inspections of your roof at least twice a year, looking for signs of damage or wear.
• Clean Gutters: Clear gutters of debris to prevent water backup and ice dam formation.
• Proper Ventilation: Ensure adequate attic ventilation to regulate temperature and moisture levels.
• Trim Overhanging Trees: Branches can cause damage to the roof, including the felt underlayment.

Choosing the Right Roof Felt

Selecting the appropriate roof felt depends on various factors, including climate, roof pitch, and budget. Consult with a roofing professional to determine the best option for your specific needs.

Factors to Consider When Choosing Roof Felt:

• Climate: Consider the prevailing weather conditions in your area. For regions with heavy snowfall, a thicker felt may be necessary.
• Roof Pitch: Steeper roofs require a more durable felt to withstand the increased weight and potential sliding.
• Budget: Roof felt options vary in price, so consider your budget when making a decision.

Comparison with other roofing materials

Roof felt, as we’ve established, is a critical underlayment, but it’s not the only player in the roofing game. Let’s compare it to some other common roofing materials.

Roof Felt vs. Asphalt Shingles

• • Advantages: Cost-effective, variety of styles, easy to replace.   
  • Disadvantages: Shorter lifespan compared to some materials, susceptible to wind damage, and less environmentally friendly.   

    Asphalt Shingles: The most popular roofing material, known for affordability and ease of installation.

• Comparison: Roof felt is a crucial component beneath asphalt shingles, providing essential protection. While shingles are the visible layer, the felt is the unsung hero working to extend the shingle’s life and prevent leaks.

Roof Felt vs. Metal Roofing

• Metal Roofing: Durable, long-lasting, and often energy-efficient.
  • Advantages: Longevity, fire resistance, eco-friendly, and often aesthetically pleasing.
  • Disadvantages: Can be noisy in heavy rain, higher initial cost, and professional installation is usually required.

     
• Comparison: Similar to asphalt shingles, metal roofing benefits from a layer of roof felt underneath. The felt provides additional protection against leaks and helps to insulate the roof.   

Tile Roofing

• Advantages: Long lifespan, fireproof, and adds value to a home.
  • Disadvantages: Heavy, expensive, and professional installation is necessary.
  • Tile Roofing: Known for its durability, aesthetic appeal, and fire resistance.
• Comparison: Roof felt is commonly used under tile roofs, providing a waterproof barrier and protecting the roof deck from moisture.   

Synthetic Roofing

• • Advantages: Variety of styles, durability, and often lighter weight than traditional materials.   
• Disadvantages: Can be more expensive than traditional options.   

• Synthetic Roofing: Modern materials designed to mimic other roofing materials, offering durability and aesthetic appeal.
• Comparison: Like other roofing materials, synthetic roofing benefits from a layer of roof felt. The felt protects the synthetic material and the underlying roof deck.

While roof felt might not be as glamorous as the visible roofing material, it’s an essential component that contributes significantly to the overall performance and longevity of your roof. It provides a vital layer of protection, helping to prevent costly repairs and ensuring the well-being of your home.

Long-term savings and benefits
