The Ultimate Guide to Roofing Underlayment: Synthetic vs Felt


When embarking on a roofing project, one of the most crucial decisions to make is the type of underlayment to use. The underlayment acts as a protective barrier, safeguarding your home from water damage, mold, and other potential hazards. Two of the most sought-after options in the market are synthetic and felt materials. In this comprehensive guide, we delve deep into the characteristics, advantages, and drawbacks of both materials to aid you in making an informed choice.

Synthetic Roofing Underlayment: The Modern Choice

Synthetic roofing underlayment has gained immense popularity in recent years, and for good reasons:

  • Durability: Crafted from materials like polypropylene and polyethylene, synthetic underlayment boasts impressive strength, ensuring longevity.
  • Water Resistance: One of its standout features is its resistance to water, ensuring that your home remains dry and free from potential water damage.
  • Ease of Installation: For those considering a DIY approach or seeking a quick installation process, synthetic underlayment is a top choice. Its lightweight nature combined with its design makes the installation process seamless.
  • Mold and Mildew Resistance: Especially beneficial for regions with high humidity, synthetic underlayment is resistant to mold and mildew, ensuring a healthier living environment.

Felt Roofing Underlayment: The Time-Tested Option

Felt roofing underlayment, a staple in the roofing industry for decades, continues to be a preferred choice for many:

  • Affordability: One of the primary reasons homeowners and roofing contractors in Albany NY opt for felt is its cost-effectiveness.
  • Breathability: Felt underlayment is designed to be breathable, which is instrumental in preventing moisture buildup and subsequent mold and mildew growth.
  • Robustness: Especially in regions prone to extreme temperatures or high winds, felt underlayment stands out for its resilience and robust nature.

Making the Right Choice: Synthetic vs Felt

While both synthetic and felt underlayment have their merits, it’s essential to weigh the pros and cons tailored to your specific needs:

  • DIY Projects: If you’re a homeowner looking to undertake a DIY roofing project, synthetic underlayment, with its ease of installation, might be the way to go.
  • Budget Considerations: For those working on a tighter budget, felt underlayment, being more affordable, could be the ideal choice.
  • Climate Factors: Consider the climatic conditions of your region. If you reside in an area with extreme weather conditions, the robust nature of felt might be more suitable. On the other hand, for regions with high humidity, the mold and mildew resistance of synthetic underlayment can be a game-changer.
