Roof underlayment plays a pivotal role in ensuring the longevity and durability of your roofing system. It acts as a barrier, safeguarding your home from potential water damage, wood rot, and other external threats. At Lenox Roofing, we understand the significance of choosing the right underlayment, and in this article, we delve into the various types available and their respective benefits.

The Role of Underlayment in Roofing

Underlayment serves as a protective layer, positioned between the roof’s exterior surface and the shingles. Its primary function is to distribute the weight of the roof covering uniformly, thereby enhancing protection against potential leaks and structural harm. Moreover, it elevates the tiles from the roof deck, facilitating efficient water runoff. When correctly installed, underlayment ensures that the shingles remain dry and can adapt to seasonal temperature fluctuations.

Delving into Different Types of Underlayment

1. Felt Underlayment

Derived from natural fibers such as cotton, jute, or other cellulose-based materials, roofing felt is akin to household paper towels. It boasts strength, absorbency, and resistance to ultraviolet light. Felt stands out for its exceptional fire protection capabilities and energy efficiency. It can endure elevated temperatures without deteriorating.

2. Synthetic Underlayment

Synthetic underlayment offers a plethora of benefits over its felt counterpart. It is versatile enough to bear heavy loads while being lightweight for effortless installation. Unlike natural fibers that are prone to water absorption and fungal growth, synthetics are waterproof and impervious to insects. They remain unaffected by moisture, negating the chances of termite-induced damage.

3. Rubberized Underlayment

A superior variant of felt, rubberized underlayment is renowned for its strength, lightness, and durability. It surpasses natural materials like cotton in terms of resistance to bacterial proliferation. Installation is a breeze, as it doesn’t stretch like felt, eliminating the need for specialized equipment during deployment.

Selecting the Ideal Underlayment for Your Roof

Making an Informed Choice for Your Roof

When considering underlayment options, it’s imperative to match the material with your roof type. For instance, asphalt shingle roofs pair well with felt underlayment due to their compatibility. Mixing materials can jeopardize the roof’s waterproofing capabilities, leading to complications in the future.
