Is Synthetic or Felt Roof Underlayment Better for Your Home?

When selecting the right underlayment for your roofing system, the debate often centers around two predominant types: synthetic and felt. Understanding the benefits and drawbacks of each type is vital for the long-term protection of your home. Diamond Roofing Specialists, Inc. explains more in this article.

What Is Roof Underlayment?

A roof underlayment is a barrier installed between the roof deck and the shingles. It protects the roof deck from moisture, adds a layer of defense against severe weather, and provides a flat surface for the shingles to lay upon. Without a reliable underlayment, even a high-quality roof can suffer from water infiltration and accelerated wear.

Comparing Durability and Lifespan

Crafted from polymers and designed to withstand harsh weather conditions, synthetic underlayment doesn’t degrade as easily as its felt counterpart. Meanwhile, felt, traditionally made from natural fibers and saturated with asphalt, can absorb moisture, which may lead to deterioration over time. In contrast, synthetic materials typically boast longer life spans.

Weight and Ease of Installation

Synthetic underlayment is lighter and comes in larger rolls, reducing labor, speeding up installation, and potentially lowering costs. On the other hand, felt underlayment is heavier and associated with more labor-intensive handling and application.

Cost Considerations

Despite synthetic underlayment’s higher upfront cost, the long-term value is clear. Its resistance to tear and a lower likelihood of replacement make it a cost-effective choice over felt. For homeowners working with a tight budget, felt underlayments may appear attractive, but it’s worth considering the higher frequency of replacement and the potential for moisture-related issues.

Weather Resistance

Synthetic underlayment generally fares better against rain, snow, and ice, providing consistent protection. Moreover, some synthetic products are specifically designed with slip-resistant surfaces, providing a safer working environment for professionals during roof repair or installation.

Environmental Considerations

Synthetic underlayment, made from polyethylene or polypropylene, tends to be more environmentally friendly than felt, as many are recyclable. This is an important consideration for homeowners who are more attuned to sustainable building practices.
