Roof Underlayment: A Comprehensive Guide

When it comes to safeguarding your home against the elements, your roof plays a crucial role. But beneath the shingles or tiles lies a silent guardian that’s often overlooked—your roof underlayment. This unseen layer of protection is an integral part of your roofing system, ensuring that your investment remains secure and your home stays dry even in the harshest of weather conditions.

For homeowners or those in the market for a new roof, understanding the role of underlayment and choosing the right type is key to maintaining a secure roof. With a variety of materials, features, and price points available, there’s no one-size-fits-all solution. Whether you live in a hot or cold climate, have a steep or low-sloped roof, or are looking for the best value, there’s an underlayment that fits your needs.


What Makes A Good Roof Underlayment?

Before we dive into identifying the types of roof underlayment, it is crucial to first comprehend the essential characteristics that contribute to its effectiveness. Understanding these key features ensures that you choose an underlayment that not only enhances the durability and performance of your flooring but also addresses specific needs such as moisture protection, insulation, and sound reduction.

Waterproofing Barrier

Roof underlayment is a critical component in constructing a durable roof, serving the vital function of providing exceptional waterproofing properties. This essential layer safeguards your home against water infiltration, offering protection during the interim period before the installation of the permanent roof covering. High-quality underlayment is imperative as it is a formidable second barrier against water ingress. In scenarios where wind-driven rains or leaks occur, this additional layer ensures that your roof maintains its dryness and integrity, ultimately contributing to the longevity and resilience of your home’s roofing system.

Adds A Layer of Cold Protection

Underlayment plays a crucial role in roofing by serving as a protective barrier against ice dams, a prevalent problem during the colder months. When water freezes and thaws, it can create ice dams that accumulate at the edges of roofs. These ice formations can cause water to back up underneath the roofing materials, leading to potentially serious damage to the structure of the roof and the interior of the building. By providing an additional layer of insulation, a properly installed underlayment helps keep the roof’s surface temperature consistent, thereby preventing the conditions contributing to the growth of ice dams. This added protection is essential for maintaining the integrity and longevity of the roofing system, especially in areas prone to harsh winter weather.


Types of Roof Underlayment

Each type of roof underlayment comes with its own set of features, benefits, and suitability for different roofing materials and climates. Whether you’re a homeowner looking to make an informed decision for your next roofing project or a professional seeking to recommend the best options to your clients, understanding the differences between these underlayment types is crucial.

Asphalt- Saturated Felt

Saturated felt, also known as tar paper, has held a significant position in the roofing industry for many years. This traditional underlayment material is favored for its relatively low cost and effective waterproofing properties, making it a go-to choice for many builders and roofers. Despite its popularity, one of the drawbacks of saturated felt is its weight, which can be considerably heavier than more modern alternatives. Additionally, it exhibits less resistance to tearing, particularly before shingle installation, posing a potential challenge during the roofing process. This aspect necessitates careful handling to avoid damage that could compromise the waterproofing integrity of the roof structure.

Rubberized Asphalt

Rubberized asphalt, known for its superior tearing resistance and flexibility, represents a significant advancement compared to traditional felt materials. This innovative roofing material not only adheres exceptionally well to the roof deck but also offers an outstanding waterproofing solution. Its durability and adaptability to various weather conditions make it an ideal option for homeowners, particularly in areas with variable climates such as Atlanta. Rubberized asphalt’s enhanced performance and longevity have contributed to its growing popularity among contractors and residents looking for reliable roofing solutions.

Synthetic Underlayment

Synthetic underlayment, a contemporary evolution in roofing materials, offers unmatched performance across a wide range of environmental conditions, setting a new standard for durability and reliability. Unlike traditional materials, it is notably lightweight, significantly simplifying the handling process during installation and reducing labor time. This innovation is not only easier to install but also boasts a high tear resistance, enhancing its safety profile for workers during the installation process. Furthermore, its superior tear resistance ensures it can withstand severe weather conditions, providing homeowners with lasting protection and peace of mind.


What Is The Best Type of Roof Underlayment For Asphalt Shingles?

Given the widespread use of asphalt shingles, the most popular roofing material, many homeowners are keen to discover the optimal roof underlayment that pairs best with them. While traditionalists may lean towards felt underlayment due to its low cost, synthetic underlayment is gaining popularity and is often the best roof underlayment choice for asphalt shingles. Here’s why:

  • Weighs Less Than Felt Underlayment: Synthetic underlayment’s lightweight nature is advantageous during installation, especially on steeper roofs where excessive weight can be an issue.
  • More Durable and Safer Than Felt Underlayment: With superior tear strength and puncture resistance, synthetic underlayment is less likely to suffer damage during installation or when the roof bears the brunt of severe weather.
  • Similar Price Points to Felt Underlayment: Despite its benefits, synthetic underlayment is often priced comparably to felt, making it a cost-effective choice that doesn’t skimp on performance.

Why Structuring Your Roof Properly Is Important

A strong roof is only as good as its weakest component, and proper roof underlayment installation is an important part of the puzzle. Here are the benefits of underlayment and the reasons why working with a professional is crucial:

  • Moisture Protection: Roof underlayment guards against moisture penetration, which can lead to rot, mold, and structural damage.
  • Repair Assistance: Underlayment acts as a backup waterproofing layer during the life of the roof, allowing for time to address shingle or tile damage.
  • Extended Roof Life: Properly installed underlayment and roof covering can significantly extend the lifespan of your roof.
  • Energy Efficiency: Underlayment plays a role in preventing ice dams, which can help maintain consistent indoor temperatures and contribute to energy savings.
