The roof underlayment plays a pivotal role in the longevity and protection of your roofing system. It’s the barrier that sits atop your roof deck, providing an additional line of defense against moisture, wind, and other weather-related impacts that can compromise the integrity of your home.
When it’s time for a roof replacement, one common question arises: which underlayment material is better, synthetic or felt? Read on as WaynCo Roofing, LLC explains in this article.
Synthetic underlayment has rapidly gained popularity due to its durability and resistance to the elements. These products are made from woven or spun polyethylene or polypropylene and represent the advancement in roofing technology. They are lighter than felt, easier to install due to their lightweight nature, and often come in larger rolls that cover more area and reduce risks of seam failure.
Synthetic underlayment is also less prone to tears and can withstand heavy foot traffic during installation, making it a strong contender for longevity. Products vary by manufacturer, but on average, synthetic underlayment can last 25 to 30 years. Its resistance to mold and algae is also a notable benefit, reducing the likelihood of needing premature roof repairs.
Felt underlayment, usually made from fiberglass or polyester fleece coated in asphalt, has been a staple in the industry for decades. It offers a lower upfront cost, which may be appealing to homeowners looking at budget-friendly options for their roof replacement projects. Felt comes in two main grades, #15 and #30, with the latter being thicker and better suited for added protection.
While the initial investment for felt underlayment is less, it’s important to recognize the potential trade-offs. Felt underlayment is heavier, making installation more labor-intensive. It’s also more susceptible to water saturation and tearing compared to synthetic options. Over time, this could lead to increased maintenance costs or more frequent replacements.
Choosing between synthetic and felt roofing underlayment will depend on various factors, such as budget, the climate in your region, and your long-term roofing performance expectations. While synthetic underlayment may seem like the superior choice in terms of durability and longevity, felt underlayment might fit the needs of those prioritizing upfront cost savings or those with a roofing system that already provides substantial protection.
