Are you a homeowner wanting top-notch roof protection, or are you a roofing industry professional? This blog post is your gateway to understanding the cutting-edge options available today.

Let’s dive into the exciting world of 21st Century Roof Technology!

New underlayment technology doubles roof protection. Roofing underlayment plays an important role in how well your roofing system performs in rain, wind, snow, ice, and fire.  Asphalt shingle is the backup on top of it, ensuring a long dry life.  

For decades the material between the asphalt shingle and the structure of your home was a felt cloth soaked in asphalt.  Today, modern technology offers a far more durable long-lasting weatherproof shield between your shingle and structure.

Asphalt Felt Underlayment

Roofing felt, also called asphalt felt underlayment or just felt, is a water-resistant material. It shields the roof deck from moisture damage by installing it beneath shingles or other roofing materials.

Manufacturing asphalt-saturated felt underlayment is a straightforward process. The processing facility rolls recycled paper. Hot asphalt is then added to the roll and asphalt-saturated underlayment is formed.  It comes in two thicknesses and is occasionally doubled based on the slope of your roof.

Benefits of Asphalt Felt Underlayment

  • Water resistance: Felt underlayment is good at resisting water. It forms a barrier that stops it from getting into the roof deck and causing damage.
  • Secondary protection: If shingles or other roofing materials are damaged, felt underlayment provides a secondary layer of protection against water infiltration.https://gandacertifiedsouthroofing.com/roofing-materials-matter-in-florida/
  • Easy installation: Felt underlayment is relatively easy to install. It can be done by DIY homeowners with some basic tools and skills.
  • Affordable: Felt underlayment is one of the most economical options for roof underlayment.

Considerations When Using Asphalt Felt Underlayment

  • Durability: The downside to asphalt felt underlayment is that it wrinkles when wet; and cracks and splits in cold weather. Overtime, it degrades and ceases to function as the intended secondary protective layer.
  • Susceptible to UV damage: Felt underlayment can get damaged by the sun’s UV radiation. It should be installed quickly under shingles or other roofing materials to avoid this.
  • Moisture retention: Felt underlayment can retain moisture, which can lead to mold and mildew growth. If you live in a humid climate, you may want to consider using a synthetic underlayment instead.

If you are concerned about durability or moisture retention, you may want to consider using a synthetic underlayment instead.

Synthetic Underlayment

Synthetic underlayment is quickly growing in popularity. These lightweight sheets made of woven or spun synthetic fibers (polyethylene or polypropylene) provide a durable, weather-resistant barrier. It is easy to apply and often includes shingle or nailing patterns printed on their faces.

Because synthetic roofing underlayments are so lightweight, manufacturers can offer more square footage per roll. They’re more expensive, but they offer faster coverage because their size can boost production. Also, because the fibers that makeup it are so durable, they don’t need to be covered nearly as soon as felt does.

These qualities have made it a preferred choice for many roofing professionals. Its adoption has grown steadily. It’s a popular choice for roofing, especially in regions with specific climate considerations like Central Florida Roofs.

  • Superior Waterproofing: This underlayment is highly resistant to water and moisture, providing an effective barrier against leaks and water infiltration. It helps protect the roof deck and the interior of the structure from water damage.
  • Enhanced Durability: This is more durable and resilient compared to traditional felt. It endures tearing and puncturing well, ensuring durability during installation and long-term exposure to the elements.
  • Lightweight: Synthetic underlayment is lighter than traditional roofing felt, making it easier to handle and install. This can be especially beneficial for roofing professionals during the installation process.
  • UV Resistance: It often has strong UV resistance, enduring prolonged sunlight exposure without degradation. This can be particularly important in sunny and hot climates.
  • Tear Resistance: It is built to resist tearing. It ensures the roofing system’s integrity, even in high-wind events or rough installation handling.
  • Breathable: Numerous synthetic underlayment products allow moisture vapor to escape from the attic, preventing issues like mold or rot.
  • Non-Slip Surface: This underlayment often has a non-slip surface. It makes it safer for roofing professionals to walk on during installation and maintenance.
  • Longevity: Synthetic underlayment typically has a longer lifespan compared to traditional felt. This means it may require less frequent replacement and maintenance.
  • Recyclable: Some synthetic underlayment products are recyclable, making them an environmentally friendly choice for roofing projects.
  • Versatile: Synthetic underlayment offers versatility, as it works with various roofing materials, such as asphalt shingles, metal roofing, and more. It makes it a versatile option for different types of roofing systems.

Peel and Stick Underlayment

Peel and stick underlayment is a self-adhesive type of roof underlayment. It does not require nails or staples for installation. Typically, manufacturers blend rubberized polymers to create it. People commonly use it for flat and low-slope roofs, and it comes in both roll and sheet forms.

  • Easy installation: The self-adhesive backing eliminates the need for nails or staples, making installation faster and easier.
  • Strong adhesion: The sticky backing keeps the roof deck and underlayment securely in place.
  • Enhanced water resistance: The self-sealing properties of the adhesive help to seal around nail shanks and other penetrations. It reduces the risk of water leaks.
  • Durable: Peel and stick underlayment is more durable than asphalt felt underlayment. It is less susceptible to tearing, puncture, and UV damage.
  • Long lifespan: Peel and stick underlayment has a long lifespan. It often lasts beyond the life span of asphalt shingles.

Maintenance and Inspection

Regular roof inspections, ideally twice a year, should include checking the condition of the underlayment. Look for signs of damage, such as tears, punctures, or excessive wear, and address any issues promptly. Proper maintenance will extend the lifespan of the underlayment and contribute to the overall longevity of the roof.

In conclusion, roof underlayment is an essential component of a roofing system. It’s crucial for safeguarding the roof deck, home interior, and overall structural integrity of the building.

Understanding roof underlayment types, considerations, installation tips, and maintenance allows homeowners to make informed decisions, ensuring long-lasting roof protection.
