When deciding on the right materials for your roof installation or replacement, choosing the proper underlayment is crucial. Underlayment is a layer of material between your roof deck and the shingles which serves as an added layer of protection from the elements. Two popular types of underlayment are synthetic and felt. In this post, we’ll dive into the differences between synthetic and felt roofing underlayment and discuss which might be better for your Knoxville home.
The Basics of Felt Underlayment
Felt underlayment, also known as tar paper, has been the traditional choice for many years. It’s made from a blend of natural fibers, polyester, or asphalt-saturated felt, providing a water-resistant barrier between your roof deck and shingles. There are two main types of felt underlayment:
-
#15 felt: Thinner and less durable.
-
#30 felt: Thicker and offers better protection but at a higher cost.
Felt underlayment’s main advantages are its cost-effectiveness and ease of installation. However, it’s heavier, less durable against ripping and tearing, and can absorb moisture, which may lead to wrinkling and can affect its performance over time.
The Advantages of Synthetic Underlayment
Synthetic underlayment, a newer option compared to felt, is constructed from woven or spun polyethylene or polypropylene. This material offers several advantages:
-
Durability: It is more tear-resistant than felt, offering better protection against harsh weather conditions.
-
Weight: Synthetic underlayment is lighter, making it easier to handle and install.
-
Water Resistance: It does not absorb water, reducing the risk of mold and mildew development underneath your shingles.
-
Longevity: Synthetic materials can last longer and maintain their integrity over time.
Moreover, synthetic underlayment provides better walking conditions for roofing contractors during installation, which can be crucial for ensuring safety during roof repair or replacement projects.
Making the Right Choice for Your Knoxville Home
In choosing between synthetic and felt roofing underlayment, consider factors such as durability, climate, safety during installation, and cost. While synthetic underlayment may offer superior durability and protection, felt underlayment could be a cost-effective solution for those with budget constraints.
Before making a decision, consulting with professional roofing contractors can provide you with valuable insights tailored to your specific needs and roof type. Whether you’re embarking on a new installation, a roof repair, or a roof replacement project, ensuring you select the right materials will contribute to the long-term health and protection of your home.
