Natural fiber, high impact

By Heidi J. Ellsworth.

Sustainable ventilation meets code driven performance in 2026.

A high-performance ridge vent made from natural fibers is redefining expectations for roof ventilation systems. In a market long dominated by synthetic plastics, Roof Saver Ridge Vent from Blocksom & Co. is proving that sustainability and durability can go hand in hand. Manufactured from durable coconut husk fibers, known as coir and bonded with a proprietary adhesive, Roof Saver delivers a renewable alternative without compromising strength or longevity. The result is a continuous ridge vent designed to provide balanced airflow while standing up to the harshest weather conditions.

“Roof Saver is engineered to be the vent of choice for contractors who want performance and sustainability in one product,” says Eric Pearman, sales development and digital marketing manager at Blocksom & Co. and Fiber Bond Corporation. “We’re taking a natural fiber and turning it into a high impact ventilation solution that meets today’s code requirements and long-term performance expectations.”

Roof Saver is backed by a non-prorated 40-year warranty and meets or exceeds ventilation requirements in U.S. building codes. It carries a UL Class A Fire Rating and has earned approvals in some of the nation’s most demanding jurisdictions, including Miami-Dade. Independent testing confirms performance under 110 mph wind driven rain and snow conditions, making it suitable for high velocity hurricane zones and severe weather regions.

“Those high wind and weather approvals matter,” Pearman explains. “Contractors need confidence that the vent system will perform in extreme conditions. Roof Saver has been tested to meet those standards.”

Installation is designed to be efficient and contractor friendly. The bristled coir structure allows nails to penetrate cleanly, helping create a smooth, consistent ridgeline beneath ridge caps. Because the material is resilient yet flexible, it conforms to roof slopes while maintaining airflow. Pearman notes that proper nail gun pressure helps preserve the vent’s structure and finish, typically in the 80 to 100 psi range depending on conditions.

Balanced ventilation remains critical to system performance. Current building codes require a 50/50 split of net free ventilation area between ridge and soffit vents to maintain proper airflow. That balance prevents pressure imbalances that can pull insulation or debris into the attic and ensures that hot, moisture laden air can escape effectively.

“Ridge ventilation only works when it’s part of a balanced system,” Pearman says. “You need adequate intake at the soffits and exhaust at the ridge to protect the attic space and the roofing assembly.”

Ventilation requirements can also vary depending on whether a vapor barrier is present. In attics with a vapor barrier, one square foot of ventilation is typically required for every 300 square feet of attic space. Without a vapor barrier, that requirement may double. Understanding these ratios helps contractors design systems that comply with code and protect warranties.

For roofing professionals seeking a ridge vent that checks every box, from sustainability and code compliance to high wind performance and ease of installation, Roof Saver offers a clear advantage. Its natural fiber composition reduces reliance on petrochemical plastics while delivering the strength and airflow performance demanded in 2026.
