Underlayment is the first layer to be put down on the roof deck, sitting beneath the shingles or any other roofing materials. No matter what type of roofing material you choose, it’s crucial to start with a solid underlayment. It serves as an extra shield against water, boosting your roof’s ability to fend off moisture damage.
Think of it as your roof’s backup plan, keeping your home’s interior safe from leaks and water damage. Choosing a robust underlayment is just as important as opting for top-quality roofing materials. Even the finest shingles or tiles won’t perform well if the underlayment doesn’t hold up and provide effective protection.
Today, we’ll take a quick look at some of the best roof underlayment options and the brands to consider when it’s time to upgrade your roof.
Several types of roof underlayment are commonly used with asphalt shingle roofing systems. Each type serves a specific purpose and offers different benefits. Here are the most popular options available on the market.
Also known as felt paper or tar paper, asphalt-saturated felt was traditionally the most common type of underlayment used with asphalt shingles. It consists of organic or fiberglass mats saturated with asphalt. Asphalt-saturated felt provides an additional layer of protection against water infiltration that helps prevent shingle resin from sticking to the roof deck during periods of high temperatures.
Synthetic underlayment is a more modern alternative to asphalt-saturated felt. It is made from synthetic polymers such as polyethylene or polypropylene materials and offers several advantages over traditional felt paper. Synthetic underlayment is lightweight, which makes it easier to handle during installation too.
It is also tear-resistant and offers better resistance to UV exposure in comparison to felt paper. Synthetic underlayments often have improved traction, which can ensure and enhance safety for contractors working on the roof.
Rubberized asphalt underlayment combines the properties of asphalt-saturated felt with added rubber modifiers. This type of roofing underlayment has superior waterproofing capabilities and offers enhanced durability compared to standard felt and even synthetic underlayments.
This type of underlayment is often used in areas prone to high winds or heavy rainfall, as it provides an extra layer of protection against water penetration.
The choice of the best roof underlayment for asphalt shingles depends on various factors, including your local climate, budget, and the specific requirements of your roofing project. We’ll get into these further later, but for now, here are some popular products that are often considered among the best:
The Grace Ice & Water Shield® HT protects the roofs of many homes in Mississippi. It is a fully adhered, smooth surface roofing underlayment that is specifically designed for high-temperature applications, This not only makes it a go-to choice for shingle roofs, but other roof systems too, such as metal and tile.
This underlayment from GAF is cost-effective and protects against moisture that slips past shingles and leaks through to the attic. This product is also an essential part of the GAF Lifetime Roofing System and comes with the prestigious Good Housekeeping seal, which further proves the reputation this product has in the industry.
Another great product to mention is the CertainTeed RoofRunner. From its humble beginnings in 1904, CertainTeed has developed a name for itself in the industry and has become one of the leading brands in the country.
The RoofRunner is a premium, synthetic polymer-based roof underlayment that will complement your asphalt shingles and add much-needed durability.
The Tyvek Protec 120 underlayment is designed to provide a reliable and durable secondary barrier against water infiltration and the weather, contributing to the longevity and performance of residential roofing systems.
Owens Corning is a well-known manufacturer of roofing materials and insulation products. The ProArmor roof underlayment is one of the best on the market as it’s designed to enhance the performance and longevity of residential roofing systems by providing an added layer of protection against the elements.
Several factors influence the choice of roof underlayment for asphalt shingles. Here are some key considerations:
Climate plays a significant role in determining the type of underlayment you’ll need. Areas with high rainfall or frequent storms may benefit from underlayment with enhanced water resistance, such as synthetic underlayment or rubberized asphalt underlayment. Similarly, regions with extreme temperatures might require underlayment that can better handle high temperatures in order to prevent shingle damage.
The pitch or slope of the roof affects how water drains off the surface. Steeper roofs shed water more quickly, while low-slope roofs may experience pooling. Underlayments must be selected accordingly to provide efficient and effective water resistance and prevent water infiltration.
Local building codes and regulations may read out specific needs for roof underlayment based on factors such as climate, wind resistance, and fire resistance. It’s essential to comply with these regulations to ensure the safety and structural integrity of the roof.
The cost of underlayment materials varies depending on factors like material type, quality, and brand. As a homeowner, you should consider your budget constraints while balancing the need for durability and performance.
