In this 2500-word blog post, we’ll cover everything you need to know, from the basics to expert tips and FAQ answers.

What Is Roofing Underlayment?

Roofing underlayment is a crucial layer in your roofing system that often goes unnoticed but plays a vital role in protecting your home. It is the barrier between the roof deck and the roofing material itself. Here are the key functions of roofing underlayment:

  • Waterproofing: Denver’s unpredictable weather can bring heavy rainfall and snow. Roofing underlayment prevents water from seeping into your home.

  • Temperature Regulation: With Denver’s extreme climate, proper underlayment helps regulate indoor temperatures, keeping your home comfortable year-round.

  • Protection Against Ice Dams: Ice dams can wreak havoc on your roof during Denver winters. The right underlayment with ice dam protection can prevent this issue.

Types of Roofing Underlayment

1. Asphalt-Saturated Felt


  • Cost-effective
  • Decent waterproofing


  • Not as durable as some alternatives

Asphalt-saturated felt, also known as felt paper or tar paper, has been a traditional choice for roofing underlayment. While it provides good waterproofing and is budget-friendly, it may not stand up as well to Denver’s challenging climate.

2. Synthetic Underlayment


  • Excellent durability
  • Superior water resistance
  • Lightweight and easy to install


  • Slightly higher upfront cost

Synthetic underlayment is gaining popularity in Denver due to its impressive durability and resistance to moisture and UV rays. It’s a smart choice for long-term protection.

3. Rubberized Asphalt


  • Combines the benefits of asphalt-saturated felt with added flexibility
  • Self-sealing properties


  • Pricey

Rubberized asphalt underlayment offers flexibility and self-sealing properties while maintaining waterproofing capabilities. It’s well-suited for Denver’s variable weather conditions.

4. Radiant Barrier Underlayment


  • Enhances energy efficiency
  • Reflects heat away from your roof


  • Higher initial cost

For homeowners focused on energy efficiency, radiant barrier underlayment is an excellent choice. It reflects heat, helping to keep your home cooler during Denver’s scorching summers.

How to Choose the Right Roofing Underlayment

Selecting the appropriate roofing underlayment for your Denver roofing project depends on various factors. Here’s how to make the right choice:

1. Consider the Climate

Denver experiences a wide range of weather conditions, from heavy snowfall to scorching summers. If you live in an area with frequent rain or snow, prioritize underlayment with exceptional waterproofing.

2. Set a Budget

While some underlayment options may have a higher upfront cost, they often provide long-term savings due to their durability and energy-efficient properties. Carefully assess your budget to make an informed decision.

3. Know Your Roofing Material

Different roofing materials may require specific types of underlayment for optimal performance. Consult with your roofing contractor to ensure compatibility.

4. Evaluate Roof Slope

The slope of your roof affects how moisture drains off. Discuss this with your roofing professional to select the right underlayment that ensures efficient water runoff.

Installation and Maintenance

Proper installation of roofing underlayment is critical to its effectiveness. Ensure it’s installed by experienced professionals who understand the nuances of Denver’s climate. Additionally, periodic inspections and maintenance can extend the lifespan of your roofing underlayment.
