Conditions of use  

Valleys are inward roofing bends exposed to rain and snow loads that are dozens of times those borne by the other elements.

RUFLEX’s designers developed RUFLEX VIO, an innovative material for protection of roofing valleys. Because the material base is polyester, it has increased strength, flexibility and stability at high temperatures and, accordingly, even higher resistance to aggressive external impacts. 

RUFLEX VIO valley coverings are colored to match the color of the surrounding shingles.

This valley covering solution rules out any ingress of moisture, for example, during a slanting rain, and provides unobstructed run-off of melt and rain water.

Valley colors: Terracotta, Gray, Heather, Dune, Green, Golden Sand, Hoarfrost, Brown, Red, Lichen, Copper, Dark Blue, Black.
