As the demand for safer, more durable roofing solutions continues to grow, synthetic roofing underlayment is rapidly replacing traditional asphalt felt in both residential and commercial construction.

Compared to felt, synthetic underlayment offers superior waterproofing, tear resistance, and a lighter weight, making installation faster, safer, and more efficient. With enhanced slip resistance and long-lasting weather durability, synthetic products are especially valuable on steep-slope roofs and in harsh climates.

“Adoption of synthetic underlayment has more than doubled in the last two years,” said one industry analyst. “Contractors and roofing professionals are making the switch not just for performance, but for the long-term savings and reliability.”

Sustainability is also driving the shift. Leading brands like MOUNTAIN BIGFOOT BARRIER are producing underlayments made from 100% recyclable materials, aligning with the growing demand for eco-friendly building solutions.

With ongoing improvements in technology and cost-efficiency, synthetic underlayment is expected to become the standard across North America within the next 3–5 years—delivering better protection and more value to roofing professionals and property owners alike.
