VIDEO: Tri-Flex® is Better Than Felt

"The Tri-Flex® synthetic felt was amazing. The amount that you get out of one roll is about four to five times more than you would get on a (typical) 50-pound [22 kilo] roll. It's a lot more durable than regular tar paper". 

"It also does not absorb any moisture—there are no fibres in it. It will last for six months as long as you use plastic caps". 

Tri-Flex® is a mechanically-attached synthetic roofing underlay that overcomes the deficiencies associated with roofing felt. Tri-Flex® is a water-shedding membrane used to prevent water damage in case the primary roof covering (such as shingles) is breached. Roofing contractors explain why they choose Tri-Flex®.
