How Roof Underlayment Works with Roofing Shingles to Prevent Leaks?

Roof Underlayment: What Does it Do?

When the rain pours, the space between your shingles and your roof can make all the difference between a dry home and soggy surroundings. A big part of the protection your roofing provides comes from the roof underlayment.

This protective barrier is placed directly onto your roofing deck, sealing in heat, minimizing unrestricted airflow, and preventing moisture penetration. So, your home or business stays protected no matter the season or weather.

Types of Roof Underlayment

There’s more than one type of roof underlayment out there! These options are used for different climates and roofing types, and include:

Felt Underlayment

This budget-friendly option, made from asphalt or fiberglass adhered to felt backing, is a go-to way to protect your roof, but it is not as durable or water-resistant as more modern materials.

Synthetic Underlayment

This lightweight material offers superior moisture protection and quickly becomes a standard for modern roofing thanks to its sheer durability.

Rubberized Asphalt

This option is excellent for regions with heavy rainfall and ice exposure. It’s self-sealing and provides a waterproof alternative for multi-angled roofs.

Radiant Barrier Roof Underlayment

This roof underlayment is designed for energy efficiency and features a reflective layer that blocks and minimizes heat transfer. Radiant Barriers are an excellent option for hot climates.

Tyvek Roof Underlayment

This high-density material is known for its durability and breathability, allowing moisture to escape while preventing penetration.

High-Temp Roof Underlayment

This roofing underlayment handles roofs regularly exposed to high temperatures, such as factories and industrial environments.

How Underlayment Works with Roofing Shingles to Prevent Leaks?

No matter how you cut it or what type you use, roof underlayment and shingles are the MVP of any roofing job. These materials prevent water intrusion, improve your structure’s insulation, and provide extra defense from storm and wind damage. But how do they work together to create such an excellent combination?

This partnership is all about layered protection. Shingles take the brunt of the sun, wind, and rain, while the underlayment stops anything that might slip through the cracks. This system can reduce water penetration, moisture damage, and greatly extend the life of your roof, especially in areas like North Carolina that see regular rainfall.

Knowing When Your Roof Underlayment is in Need of Repair

Since even the best roofs offer a limited lifespan, your underlayment will likely need repairs or replacement within your lifetime. But how can you tell? There are several ways.

Your first insight will be leaks from the roofing deck into your attic or crawlspace. This is where moisture first penetrates the underlayment, and water enters your home.

In more severe cases, you’ll notice spotting on ceilings, water damage, water pooling, and even interior roof failures due to water retention, so it’s best to make simple repairs as soon as they appear.

Shingle Underlayment Installation

Unfortunately, installing underlayment isn’t always as simple as rolling out sheets and nailing them down. Each of the above underlayment systems has unique installation requirements, and not having a working knowledge of these differences can significantly reduce its effectiveness in the field.

For example, asphalt-saturated felt will be secured with staples, while rubberized asphalt will feature an adhesive backing that can be tough to reposition if not laid correctly. It’s always better to leave it to the professional touch in these situations.
