The Roof Underlayment, Explained

When it comes to protecting your home from the elements, the significance of a robust roofing system cannot be overstated. While most discussions about roofing focus on visible components like shingles, an equally vital but less visible player in this system is the roof underlayment.

What is Roof Underlayment?

Roof underlayment serves as a critical barrier positioned between your roof’s shingles and the structural deck. It plays several vital roles that enhance the longevity and effectiveness of your roof. There are primarily three types of underlayment utilized in roofing systems: asphalt-saturated felt, rubberized asphalt, and non-bitumen synthetic underlayment. Each type offers different benefits and suits various roofing requirements, from enhancing water resistance to providing superior durability in high winds or when temporary exposure is inevitable.

Importance of Roof Underlayment

In areas where weather conditions can range from intense sun and heat in the summer to ice, snow, and rainy seasons, the right underlayment can mean the difference between a roof that lasts and one that needs premature repairs. For instance, rubberized asphalt underlayment offers waterproof protection for areas prone to ice dam formation. Non-bitumen synthetic underlayment might be preferred for its durability and resistance against UV rays and mold, which is crucial for the hot summer.

Types of Roof Underlayment

Asphalt-Saturated Felt: Once the go-to option for roofers, this underlayment is made from an organic or fiberglass base, saturated with asphalt. It’s less expensive than its alternatives but can be heavier and less durable under certain conditions.

Synthetic Underlayment: This category has gained popularity due to its numerous advantages, such as being lightweight, offering superior tear resistance, and better withstand prolonged exposure to weather elements.

Rubberized Asphalt: Known for its waterproofing capabilities, this self-adhering underlayment seals well around roof fasteners, making it an excellent option for valleys, eaves, and other areas prone to water collection. Though more costly, its benefits are undeniable, especially in preventing water damage.

Choosing the Right Underlayment for Your Tulsa Home

The selection of the appropriate underlayment should align with Tulsa’s specific weather patterns, your roofing material, and the architectural design of your home. Factors such as exposure to high temperatures, susceptibility to ice dams, and preference for eco-friendly materials will guide homeowners and professionals in making informed decisions.

The Role of Roof Underlayment in Roofing Systems

Apart from providing an extra layer of protection against water infiltration, roof underlayment also:

  • Safeguards the roof deck during and after the installation process, preventing it from being exposed to the elements.

  • Enhances the fire resistance of the roofing system when used with materials that achieve a specific fire rating.

  • Improves roof stability by offering a better surface for shingles to adhere to, which is particularly important in windy conditions.
