Synthetic vs. Felt Roofing Underlayment: An In-Depth Analysis

by | Mar 12, 2024

When it comes to roofing, there’s more than meets the eye. Beyond the visible shingles or metal roofing, there’s a crucial layer that plays a pivotal role in safeguarding your home against moisture damage: the roofing underlayment. At BLC Roofing, we understand the importance of this component and aim to provide our clients with the best solutions tailored to their needs.

Understanding Roofing Underlayment

Roofing underlayment serves as a barrier between the shingles and the roof sheathing, typically made of plywood or OSB. This layer is directly installed on the roof deck, offering an additional shield against elements like rain, snow, and wind.

The Two Main Contenders: Felt vs. Synthetic

Felt Roofing Underlayment

Originating as one of the earliest types of roofing underlayment, felt is produced by saturating paper or fiberglass mat with asphalt. It’s available mainly in two variants: No.15 felt and No.30 felt. The latter is generally thicker and more robust, making it less susceptible to damage during installation or adverse weather conditions.

Advantages:

  • Cost-Effective: Felt underlayment is often the preferred choice for homeowners on a tight budget.

Disadvantages:

  • Limited Exposure Time: Traditional felt underlayment shouldn’t be left exposed for extended periods.
  • Vulnerability to Tearing: Especially during installation or in high winds.
  • Moisture Absorption: Can lead to wrinkling, affecting shingle placement.
  • Heavier Weight: Makes it challenging for roofing services in Akron OH to transport and install.
  • Potential Warranty Issues: Some manufacturers may require synthetic underlayment for warranty coverage.

Synthetic Roofing Underlayment

Crafted from durable polymers, synthetic roofing underlayment offers enhanced protection against the elements. Its performance can vary based on the manufacturer, so it’s essential to research and consult with trusted roofing companies from Akron OH.

Advantages:

  • Durability: Synthetic underlayment boasts high tear strength.
  • Extended Exposure: Can withstand prolonged UV and moisture exposure.
  • Lightweight: Easier for roof repair service in Akron OH to handle and install.
  • Safety: Features slip-resistant surfaces for better walkability during installation.
  • Moisture Repellent: Unlike felt, synthetic underlayment is designed to repel water, making it an excellent choice for homeowners concerned about potential moisture damage.

Disadvantages:

  • Cost: While many synthetic options are competitively priced, they might be more expensive than felt. However, the long-term benefits often justify the initial investment.

Making the Right Choice for Your Home

Whether you’re considering a roof replacement service in Akron OH or constructing a new home, the type of underlayment you choose can significantly impact the longevity and performance of your roof. Synthetic roofing underlayment, with its myriad advantages over felt, can be a valuable investment to shield your home from potential water and moisture damage.
