What is Roof Underlayment?
A vital component of any roofing system, roof underlayment serves as the protective layer between the roofing material and the underlying structure of your building. And while it may often get overlooked, this element is a critical part of an effective roof.
One of the primary functions of roof underlayment is preventing moisture infiltration from rain, snow, or ice that could otherwise penetrate through to your roof deck. By preventing water from breaching this barrier, you’ll significantly reduce the possibility of leaks, rot, and costly structural damage.
If you live in a region that regularly experiences heavy rain, snow accumulation, or ice, having a high-quality underlayment layer is a critical part of extending your building’s lifespan.
Types of Roof Underlayment
While shingles and tiles get most of the love in the roofing industry, we can’t understate the role roof underlayment plays in the overall health of your roof. Let’s look at just a few types of roof underlayment:
1. Felt Underlayment
Felt underlayment is made from organic or fiberglass materials coated with asphalt for waterproofing and has been a staple in roofing for decades. It’s known for its affordability and durability, making it a popular choice for many roofing projects. It is typically available in rolls and is easy to handle and install. However, it’s important to note that felt underlayment may not be as resistant to tearing or wrinkling during installation as some newer options.
2. Self-Adhered Underlayment
As the name suggests, self-adhered underlayment comes with a built-in adhesive layer that simplifies installation. It is often used in roofing projects where ease of application and reliability are paramount. This underlayment adheres directly to the roof deck, creating a strong bond that helps prevent water infiltration. Self-adhered underlayment is highly resistant to wind-driven rain and is a favorite in areas prone to severe weather conditions.
3. Synthetic Underlayment
Synthetic underlayment is typically made from lightweight polypropylene or polyethylene and has gained popularity in recent years due to its versatility and durability. Synthetic underlayment offers excellent waterproofing and is often chosen for its resistance to mold and UV rays. It is also less prone to wrinkling and can be left exposed for longer periods during the roofing process without losing integrity.
4. Radiant Barrier Roof Underlayment
Radiant barrier roof underlayment is a specialized underlayment designed to improve energy efficiency. It features a reflective layer that helps block heat from the sun’s rays, reducing heat transfer into the building. It is particularly useful in hot climates or homes with attic spaces where temperature control is essential.
5. Tyvek Roof Underlayment
Tyvek roof underlayment is a high-density polyethylene material that provides excellent moisture resistance. It’s known for its durability and breathability, allowing moisture vapor to escape while preventing water from entering, and is often used in areas with high humidity or as a secondary moisture barrier for added protection.
6. High-Temperature Roof Underlayment
High-temperature roof underlayment is specially designed for roofs with high-temperature requirements, such as those with metal roofing or in areas with extreme heat. It can withstand the elevated temperatures associated with these roofing materials without degrading or compromising its protective qualities.
Why is Roofing Underlayment Necessary?
Roofing underlayment may not be visible from the street, but it plays an important role in the life of your roof. This hidden layer is a crucial component of the protective capabilities of your roof. It serves as a moisture barrier against rain, snow, and ice and can even keep your roof leak-free after shingles have become damaged.
It also works well for temperature regulation, insulating your home, reducing airflow, and promoting a more comfortable environment for you and your family. And, finally, it can greatly extend the lifespan of your roofing system by preventing issues that can grow if left unchecked. This can save you tremendously in heating and repair costs over the life of your building.
How Much Does Roof Underlayment Replacement Cost?
In most cases, you can expect roof underlayment replacement to range between $.75 and $5 per square foot, depending on your roof size, type, and the material you use. However, it’s important to note that roof underlayment is only a single component of a larger roofing system. As such, replacing one will often necessitate the replacement of the entire roof, shingles, and all. As such, the full price for your underlayment replacement may be more than you might think at first glance.
