Synthetic Underlayment for Roofing

When it comes to roofing, every component plays a crucial role in ensuring the longevity and effectiveness of the roof system. One such critical component is the underlayment. Traditionally, the asphaltic felt paper has been the go-to underlayment material, but advancements in roofing technology have introduced synthetic underlayments, which offer several advantages over their felt counterparts. In this comprehensive blog, we will explore the various aspects of synthetic underlayments, their benefits, and why they might be the best choice for your roofing needs.

What is Synthetic Underlayment?

Synthetic underlayment is a type of roofing material that serves as a protective barrier between the roofing deck and the shingles. Unlike traditional felt paper, synthetic underlayments are made from polypropylene or polyethylene, providing a more durable and reliable option for modern roofing systems. They are engineered to provide superior protection against the elements, including water, wind, and UV radiation, which can significantly enhance the overall performance and lifespan of your roof.

Benefits of Synthetic Underlayment

1. Enhanced Durability and Longevity

Synthetic underlayments are designed to withstand harsh weather conditions, including high winds, heavy rain, and extreme temperatures. They are resistant to tearing, which is a common issue with felt paper. This durability ensures that synthetic underlayments provide a longer lifespan, often outlasting the shingles themselves. Additionally, synthetic underlayments are less likely to degrade over time, maintaining their protective qualities for decades.

2. Improved Water Resistance

One of the primary functions of underlayment is to act as a secondary water-shedding layer. Synthetic underlayments excel in this aspect due to their superior water-resistant properties. They prevent water from seeping into the roofing deck, reducing the risk of leaks and water damage over time. This is particularly important in regions that experience heavy rainfall or snow, as water infiltration can lead to significant structural damage and costly repairs.

3. Safer for Roofers

Safety is a paramount concern in roofing. High-quality synthetic underlayments, such as GAF Tiger Paw, are designed with extra-gripping walkability, making them safer for roofers to walk on during installation. This feature significantly reduces the risk of slips and falls, which are common hazards when working with traditional felt paper. The enhanced traction provided by synthetic underlayments can help prevent accidents and injuries, ensuring a safer working environment for roofing professionals.

4. Better for Long-Term Performance

Felt underlayment tends to degrade over time, especially after 20-30 years. This degradation can compromise its water-shedding capabilities, leading to potential issues like leaks and roof damage. Synthetic underlayments, on the other hand, maintain their integrity for much longer, contributing to the overall longevity and performance of the roofing system. Manufacturers often offer extended warranties on roofing systems that include synthetic underlayment, reflecting their confidence in the material’s durability and effectiveness.

5. Reduces the Risk of Shingle Rippling

Felt paper often does not lay perfectly flat, which can cause shingles to ripple and create an uneven appearance on the roof. Synthetic underlayments roll out smoothly and flat, ensuring a uniform and aesthetically pleasing finish. This helps in maintaining the visual appeal of the roof and prevents potential structural issues related to uneven shingle placement. A smooth, flat underlayment layer provides a better foundation for shingle installation, reducing the likelihood of future roofing problems.

Synthetic Underlayment vs. Felt Paper

While traditional felt paper has been used for decades, synthetic underlayments offer several advantages that make them a superior choice for modern roofing systems. Here are some key comparisons:

Durability and Lifespan

• Felt Paper: Prone to tearing and degradation over time, usually lasting 20-30 years.
• Synthetic Underlayment: Highly durable, resistant to tearing, and can last as long as the shingles themselves.

Water Resistance

• Felt Paper: Provides basic water resistance but can absorb moisture, leading to potential leaks.
• Synthetic Underlayment: Excellent water resistance, preventing moisture penetration and reducing the risk of leaks.

Safety

• Felt Paper: Slippery and can pose a safety hazard for roofers.
• Synthetic Underlayment: Designed with extra-gripping surfaces, enhancing safety during installation.

Installation and Aesthetics

• Felt Paper: Can cause shingles to ripple due to uneven laying.
• Synthetic Underlayment: Rolls out smoothly, ensuring a flat and uniform shingle installation.

When to Use Synthetic Roof Underlayment

New Roof Installations

For new roof installations, synthetic roof underlayment is highly recommended due to its superior performance, durability, and safety features. It provides a strong foundation for the roofing system, ensuring long-term protection and reliability. Synthetic underlayments are suitable for a wide range of roofing materials, including asphalt shingles, metal roofing, and tile.

Roof Replacements

When replacing an old roof, especially if it previously had felt underlayment, upgrading to synthetic underlayment can significantly enhance the overall quality and lifespan of the new roof. This upgrade is particularly beneficial in areas prone to harsh weather conditions. Homeowners looking to maximize the return on their roofing investment should consider the long-term benefits of synthetic underlayments.

Over Solid Roof Decks

Homes with solid roof decks benefit greatly from synthetic underlayment. Unlike felt, which can absorb moisture and cause damage to the deck, synthetic underlayments provide robust protection against water penetration, preserving the integrity of the roof structure. This is especially important for homes with attic spaces, as moisture infiltration can lead to mold growth and other indoor air quality issues.

The Cost Factor

While synthetic underlayments typically have a higher upfront cost compared to felt paper, their long-term benefits outweigh the initial investment. The enhanced durability, improved safety, and extended lifespan result in lower overall maintenance and replacement costs. Moreover, the reduced risk of roofing issues, such as leaks and shingle rippling, adds to the cost-effectiveness of synthetic underlayments.

Long-Term Savings

Investing in synthetic underlayment can lead to significant long-term savings. By preventing water damage, reducing the risk of accidents during installation, and extending the life of the roofing system, synthetic underlayments help homeowners save on repair and replacement costs. Additionally, many synthetic underlayments come with extended warranties, providing peace of mind and financial protection.

Environmental Considerations

Synthetic underlayments are also an environmentally friendly choice. Their durability means fewer materials are needed over the life of the roof, reducing waste. Some manufacturers also offer recyclable options, further minimizing the environmental impact. Choosing a sustainable roofing solution can contribute to a greener future while ensuring the highest level of protection for your home.

Choosing the Right Synthetic Roofing Underlayment

Not all synthetic underlayments are created equal. It’s essential to choose a high-quality product that meets industry standards and provides the necessary features for your specific roofing needs. Some factors to consider include:

Thickness and Durability

Opt for synthetic underlayments that offer a good balance between thickness and flexibility. Thicker materials tend to be more durable and provide better protection. However, they should also be easy to handle and install, ensuring a smooth application process.

Water Resistance

Ensure the synthetic underlayment has excellent water-resistant properties to protect your roof deck from moisture damage. Look for products with high water vapor transmission rates to allow for adequate breathability while maintaining superior water resistance.

UV Resistance

Some synthetic underlayments are designed to withstand UV exposure for extended periods. This feature is particularly useful in areas with high sun exposure, preventing degradation and extending the underlayment’s lifespan. UV-resistant underlayments are especially important for roofs that may be exposed to the elements for longer periods before shingle installation.

Brand Reputation

Choose synthetic underlayments from reputable manufacturers known for their quality and reliability. Brands like GAF Tiger Paw are well-regarded in the industry for their superior performance and safety features. Research customer reviews and industry certifications to ensure you are selecting a product that meets your expectations and requirements.

Installing Synthetic Underlayment

Proper installation is crucial for maximizing the benefits of synthetic underlayment. Here are some key steps involved in the installation process:

Surface Preparation

Ensure the roof deck is clean, dry, and free of debris before installing the underlayment. Any imperfections or contaminants can affect the underlayment’s adhesion and performance. Inspect the deck for any signs of damage or rot and make necessary repairs to provide a solid foundation.

Rolling Out the Underlayment

Start at the bottom edge of the roof and roll out the synthetic underlayment horizontally, overlapping each row by the recommended amount (usually 4 inches). Secure the underlayment with roofing nails or staples, following the manufacturer’s guidelines. Make sure the underlayment is laid flat and free of wrinkles or bubbles, which can compromise its effectiveness.

Sealing and Flashing

Pay special attention to areas prone to water infiltration, such as valleys, roof penetrations, and edges. Use appropriate sealants and flashing materials to ensure a watertight installation. Proper sealing around vents, chimneys, and skylights is critical to prevent leaks and ensure the long-term performance of the underlayment.

Final Inspection

After installing the underlayment, perform a thorough inspection to check for any gaps, wrinkles, or loose edges. Address any issues promptly to ensure the underlayment provides optimal protection. A detailed inspection will help identify potential problems early, allowing for corrective measures before shingle installation.

Conclusion

Synthetic underlayments represent a significant advancement in roofing technology, offering numerous benefits over traditional felt paper. Their enhanced durability, superior water resistance, improved safety features, and long-term cost-effectiveness make them an ​

ideal choice for modern roofing systems. Whether you’re installing a new roof or replacing an old one, opting for synthetic underlayment can ensure your roof performs at its best for years to come. By investing in this advanced material, homeowners can enjoy peace of mind knowing their roof is well-protected against the elements, providing reliable service and maintaining its aesthetic appeal.
