MALVERN, Penn. — CertainTeed has released SmartFlash ONE, a one-component, UV-stable, fluid-applied resin for steep and low-sloped roof flashing details and repairs.

SmartFlash ONE offers roofing contractors an economical and convenient waterproofing solution in a ready-to-use, re-sealable can that requires no measuring or mixing to activate.

According to Abby Feinstein, commercial roofing product manager for CertainTeed, the ability for SmartFlash ONE to be applied without a primer and resealed for future use gives contractors an edge in terms of time, cost and ease of installation.

“SmartFlash ONE delivers one-part labor efficiency with two-part performance,” said Feinstein. “With no primer or component mixing, contractors can work quickly without fear of the product setting up too fast or going to waste.”

CertainTeed is so confident in the stress resilience and UV stability of the formula that the building materials manufacturer is supporting the product with up to 20 years of warranty coverage, which is in line with the coverage afforded to two-part solutions.

SmartFlash ONE resin is available in a five-gallon pail (125 square-foot coverage) or a one-gallon pail (25 square-foot coverage). The one-gallon pail is available à la carte or as part of a Flash Pack, which includes resin, fleece and application accessories. For more information on CertainTeed commercial roofing products, visit
