The materials used in roof replacement projects extend beyond just the external shingles or tiles—the underlayment beneath plays a critical role. When it comes to this particular roof component, there are two choices that come to mind: synthetic and felt. Both options offer distinct advantages, but which one is more suited for your home’s protection and longevity? Pressure Point Roofing Eugene, LLC explains what you need to know.
Understanding Roofing Underlayment
A roof’s underlayment is applied on top of the decking before the asphalt shingles, metal panels or tiles are installed. It acts as a barrier tasked with protecting your home from water intrusion and thereby preventing damage.
Felt Underlayment: The Traditional Choice
Felt underlayment has been a staple in roofing for decades. Composed of either natural fibers or fiberglass mats, saturated with asphalt, it provides a water-resistant layer beneath your roofing material. In climates where precipitation is a factor, the water resistance of felt is beneficial.
Felt underlayment, consisting of either #15 or #30 grades—the latter denoting a thicker and more durable option—is known for its ability to absorb moisture. It’s also a cost-effective option due to its long history in the market and the relatively inexpensive materials involved. However, as a heavier material, felt underlayment can be tougher to work with, potentially increasing labor costs during installation. It also has a lower tear resistance than synthetic options, and can degrade faster when exposed to prolonged sunlight or harsh weather conditions.
Synthetic Underlayment: The Modern Solution
The introduction of synthetic underlayment, predominantly made from woven polymers like polyethylene or polypropylene, brought with it significant advancements in roofing technology. Lighter and more tear-resistant than its felt counterpart, synthetic underlayment is tailored for enhanced performance.
Offering superior durability, a synthetic underlayment is less susceptible to damage during and post-installation, maintaining their integrity even in the face of varied weather patterns. They’re also lighter, which can result in quicker and safer installations. Synthetic materials resist water effectively, which is a substantial plus.
Making the Right Choice for Your Home
The decision between synthetic and felt underlayment boils down to a few factors, such as durability, weather resistance, ease of installation and cost. For those prioritizing longevity and performance, synthetic underlayment is an excellent choice, provided that the initial higher cost is not prohibitive. Conversely, felt underlayment still serves as a reliable choice, especially where budget constraints are paramount.
