Understanding the Importance of Roofing Underlayment

When it comes to roofing, the underlayment plays a crucial role in protecting your home from moisture, wind, and other elements. It is a waterproof barrier that is installed between the roof deck and the shingles or tiles. The right underlayment can greatly extend the lifespan of your roof and ensure its overall performance. With so many options available in the market, how do you choose the right roofing underlayment for your project? Let’s explore some key factors to consider.

Climate and Weather Resistance

One of the most important considerations when selecting roofing underlayment is the climate in which you live. Different regions experience different weather conditions, such as heavy rain, snow, high humidity, or extreme heat. It is crucial to choose an underlayment that is specifically designed to withstand the weather challenges in your area.

In areas with heavy rainfall, a self-adhesive or peel-and-stick underlayment is recommended as it provides excellent waterproofing. For regions with high humidity, a breathable underlayment is preferable to prevent moisture buildup and mold growth. If you live in an area prone to hurricanes or strong winds, consider an underlayment with enhanced wind resistance.

Material and Durability

Roofing underlayment comes in various materials, each with its own benefits and drawbacks. The most common types include asphalt-saturated felt, synthetic underlayment, rubberized asphalt, and peel-and-stick membranes. The choice of material depends on the specific needs of your project.

Asphalt-saturated felt is a traditional and cost-effective option that provides good waterproofing and durability. Synthetic underlayment, on the other hand, offers superior tear resistance and longevity. Rubberized asphalt combines the benefits of both materials, providing excellent waterproofing and flexibility. Peel-and-stick membranes are self-adhesive and offer superior protection against leaks.

Roofing Type and Slope

The type of roofing you have and the slope of your roof also influence the choice of underlayment. For example, metal roofs require underlayment that can withstand high temperatures and provide a good grip for the metal panels. Tile roofs often require a highly durable underlayment due to their weight and vulnerability to cracking. Asphalt shingles generally work well with most types of underlayment.

The slope of your roof is also a crucial factor to consider. Steep roofs require underlayment with high traction to prevent slipping during installation and regular maintenance. Additionally, areas prone to ice dams may benefit from an underlayment with superior ice and water resistance.

Installation Method and Cost

Consider the installation method and cost when selecting roofing underlayment. Some underlayment options require special tools or techniques, which may increase the overall installation cost. Additionally, certain materials may have a higher upfront cost but provide long-term savings due to their durability and performance.

Consult with a professional roofing contractor to understand the installation requirements of different underlayment options and their associated costs. They can help you make an informed decision based on your specific project requirements and budget.


Choosing the right roofing underlayment is essential for the long-term performance and durability of your roof. Consider factors such as climate, material, roofing type, slope, installation method, and cost when making your decision. By selecting the appropriate underlayment, you can ensure that your roof remains protected and your home stays safe and dry for years to come.
