Roof moisture relief vents.

The challenge lies in letting the roof have the vents it need and flashing them properly to keep water out. The one way vent allows trapped air pressure to escape while the two way breather combined with the one way vent will help reduce moisture. Portals plus insulation breathers and vents are used to prevent moisture vapor from becoming trapped in the roof system equalizing air pressure reducing the risks of ballooning blow off deteriorating insulation and separating deck seams. Trapped air pressure and moisture can cause a reduction in thermal protection of the insulation and roof membrane system leading to roof deck damage.
