When it comes to roofing, most homeowners focus primarily on the roof covering, such as shingles, tiles, or metal sheets. However, there's a crucial layer beneath the surface that is often overlooked but plays a significant role in the performance, durability, and longevity of the entire roofing system: roofing underlayment. Understanding the importance of roofing underlayment and choosing the right product can save you a lot of money and headaches in the long run.

What Is Roofing Underlayment?

Roofing underlayment is a protective layer installed directly under the roof covering, such as shingles, tiles, or metal roofing. It serves as an extra line of defense against weather conditions like rain, snow, wind, and ice. Typically made from materials like felt, synthetic polymers, or rubberized asphalt, underlayment helps safeguard your home from water damage and enhances the overall performance of the roofing system.

The underlayment is often considered a “secondary barrier” as it provides backup protection when the roof covering is compromised. For instance, strong winds or a shift in the roof covering might expose portions of the roof to the elements. In these cases, underlayment will continue to protect the roof structure until repairs can be made.

The Function of Roofing Underlayment

1. Waterproofing & Water Resistance
   The primary function of roofing underlayment is to prevent water from infiltrating the roof decking. Rain, ice dams, or even melting snow can find their way under the shingles or other roof coverings, leading to leaks and water damage. Roofing underlayment provides an essential waterproofing layer that prevents such issues, keeping your home dry and safe from water intrusion.

2. Protection Against Ice Dams
   In colder climates, ice dams are a significant concern. When snow accumulates on the roof and melts during the day, the water can freeze again at the eaves, forming an ice dam. This water buildup can lead to leaks in the attic. Underlayment, particularly ice and water shields, can effectively prevent the formation of ice dams by providing a continuous waterproof barrier at the vulnerable areas of the roof.

3. Improved Durability
   The additional layer of underlayment can increase the overall durability and lifespan of your roof. It acts as a protective cushion between the roof decking and the outer roof covering, reducing the chances of damage caused by excessive heat, moisture, or physical wear.

4. Enhanced Energy Efficiency
   Certain types of roofing underlayment, such as reflective underlayment, can help improve your home’s energy efficiency. Reflective underlayment reduces heat absorption, helping to maintain more stable indoor temperatures and reducing the workload of your HVAC system. This can lead to energy savings, particularly in warmer climates.

5. Wind Resistance
   Underlayment provides a secondary layer of defense against high winds. In case the roof covering gets lifted or blown off by strong winds, the underlayment can help minimize potential damage and prevent further exposure to the elements.

Types of Roofing Underlayment

Not all roofing underlayment is created equal. There are different types of materials, each with distinct properties to suit various roofing needs. The most common types include:

1. Felt Underlayment
   Traditionally, felt underlayment, also known as tar paper, has been the go-to choice for many years. Felt is made from a base of fiberglass or organic materials that are saturated with asphalt. It is relatively inexpensive but can be less durable compared to other options, especially in areas with high moisture levels. It can also deteriorate faster in direct sunlight.

2. Synthetic Underlayment
   Synthetic underlayment is a modern alternative to felt. Made from polymers and plastic, synthetic underlayment is stronger, lighter, and more durable than traditional felt. It is also less likely to tear or absorb water, making it a popular choice for homeowners seeking enhanced protection. Additionally, synthetic options are often easier to install and can withstand a wider range of temperatures.

3. Rubberized Asphalt Underlayment
   This type of underlayment consists of a rubberized asphalt membrane that offers exceptional waterproofing capabilities. It is highly effective at preventing water infiltration and is commonly used in areas prone to extreme weather conditions, such as heavy rainfall or ice dams.

4. Ice and Water Shield Underlayment
   This is a specialized version of rubberized asphalt underlayment that is specifically designed to protect against ice dams and severe weather conditions. It is often applied in areas where water infiltration is a high risk, such as valleys, eaves, and around chimneys.
