Roofing Underlayment Options That Outperform Felt
Introduction to Roofing Underlayments
Let’s start the journey by understanding the basics. Roofing underlayment is a water-resistant barrier installed directly onto your roof’s deck. It provides an extra layer of protection between your roofing material and the roof deck. While felt has been a traditional choice, the industry has evolved. Today, we have several roofing underlayment options that outperform felt in various ways. In this blog, we will dive deep into these options, comparing their advantages over traditional felt.
The Importance of Choosing the Right Underlayment
The importance of a quality roofing underlayment cannot be overstated. It plays a critical role in preventing leaks, providing insulation, and enhancing the lifespan of your roof. The right underlayment can even make your home more energy-efficient. Remember, while the top roofing material is the first line of defense, the underlayment is your last line of defense against harsh weather conditions.
The Limitations of Traditional Felt Underlayment
Felt underlayment, usually made of either organic or fiberglass substrate soaked in asphalt, has served homeowners well for decades. However, it has its limitations. Felt is susceptible to tearing, especially during installation or under heavy foot traffic. It can also wrinkle when exposed to moisture, creating imperfections that might show through the roofing material. These issues can compromise the integrity of your roof.
Synthetic Underlayment: A Popular Alternative
One of the most popular alternatives to felt is synthetic underlayment. Made from polymers such as polypropylene or polyethylene, this type of underlayment is superior in strength and durability. Synthetic underlayment is resistant to tearing, even under harsh weather, and does not absorb moisture. This makes it an ideal choice for areas with high rainfall or humidity.
Rubberized Asphalt: High Performance and Protection
Rubberized asphalt underlayment is another excellent choice for homeowners looking for an upgrade from felt. This underlayment contains higher percentages of asphalt and rubber polymers, providing a high degree of water resistance. Furthermore, this type is self-adhering, creating a tight seal around roof penetrations and providing excellent waterproofing.
Non-Bitumen Synthetics: An Eco-friendly Choice
For those looking for eco-friendly underlayment options, non-bitumen synthetics are the way to go. These underlayments are made from thermoplastics like polypropylene or polyethylene, which can be recycled. They offer the same level of protection as other synthetic underlayments but are more environmentally friendly.
Reinforced Underlayments: For High Wind Areas
If your home is in a region prone to high winds or hurricanes, consider reinforced underlayments. These types can be either synthetic or rubberized asphalt but include a layer of fiberglass for added strength. This reinforcement helps the underlayment withstand high wind speeds and shield your roof from potential damage.
Underlayment for Metal Roofs: Specialized Options
Metal roofs have their own specific underlayment requirements. Felt isn’t generally suitable as it can trap moisture leading to rusting. Instead, options like self-adhering modified bitumen or specialized synthetic underlayments, designed to handle the high temperatures associated with metal roofs, are better choices.
Underlayment Installation: Best Practices
Choosing the right underlayment is only half the battle. Proper installation is equally critical. It’s always recommended to hire a professional, experienced roofing contractor to ensure the underlayment is installed correctly. This includes properly overlapping edges, securing the underlayment with the right fasteners, and ensuring a smooth surface for the roofing material.
Wrapping Up: A Thoughtful Reflection
In conclusion, while felt has served us well in the past, there are now several roofing underlayment options that outperform felt in terms of durability, moisture resistance, and overall performance. By understanding the specifics of each type, you can make an informed decision and ensure your home gets the best protection possible. And remember, the right underlayment is an investment that pays off in the long run, through a roof that stands strong against all odds.
