BLOG Choosing the Right Roof Underlayment: Insights from Kenneth Mills Roofing & Restoration Jan 10, 2025

When it comes to roofing, the underlayment is as crucial as the shingles that cover it. At Kenneth Mills Roofing & Restoration, we understand that choosing the right roof underlayment can make a significant difference in the longevity and effectiveness of your roof. In this blog, we aim to provide insights into selecting the best underlayment for your roofing needs.

Understanding the importance of roof underlayment is the first step in making an informed decision. Roof underlayment acts as a protective barrier between the shingles and the roof deck. It serves as an additional layer of protection against moisture, extreme weather conditions, and helps in fire resistance. Without a proper underlayment, your roof is susceptible to leaks and other forms of damage.

There are primarily three types of roof underlayment: asphalt-saturated felt, non-bitumen synthetic underlayment, and rubberized asphalt underlayment. Each of these options has its unique properties, advantages, and potential drawbacks.

Asphalt-saturated felt, often recognized as tar paper, is the traditional choice and is still widely used today. It is durable and provides a basic level of protection. While it’s cost-effective and easy to install, it is less resilient to tearing and may not perform as well under extreme temperature fluctuations as synthetics.

Non-bitumen synthetic underlayment is a superior alternative for those seeking advanced protection. This type of underlayment is lightweight, waterproof, and often tear-resistant, making it easier to handle and install. Synthetics provide better protection against UV rays and can handle broader temperature ranges. Many homeowners and contractors favor this choice for its balance between performance and cost.

Rubberized asphalt underlayment offers top-tier protection. Its self-adhesive properties provide an additional seal against leaks, especially around complex areas like chimneys and skylights. It is highly resistant to water, although this option tends to be more expensive. It is often recommended for roofs in regions susceptible to heavy rain or snowfall.

Choosing the right underlayment depends largely on your specific needs and local climate conditions. For instance, if you live in an area with a high humidity level or heavy rains, a waterproof synthetic or rubberized asphalt option might be best. Conversely, if your priority is cost-effectiveness in a less extreme climate, asphalt-saturated felt could suffice.

Moreover, ensuring proper installation is key. Regardless of which underlayment you opt for, improper installation can lead to potential failures. At Kenneth Mills Roofing & Restoration, our expert team ensures precision during installation to maximize the effectiveness and longevity of the underlayment.

Besides material and installation, consider factors like warranty and compatibility with roofing material. Some manufacturers offer extended warranties when their underlayment is used, providing added peace of mind. Always verify compatibility with your chosen shingles to prevent any issues post-installation.

In conclusion, selecting the right roof underlayment is vital for the overall performance of your roof. Whether you lean towards asphalt-saturated felt, synthetic, or rubberized asphalt, each option has its merits. At Kenneth Mills Roofing & Restoration, our experienced professionals are committed to guiding you through this decision, ensuring your choice aligns with your budget, climatic conditions, and personal preferences.
