[Edge Vent](https://help.gibraltarbuildingproducts.com/en/knowledge/ventilation?hsLang=en#edge-vent) # Is there a potential for pooling water behind The Edge Vent on 3/12 & 4/12 pitch roofs? ## Water will not pool on The Edge Vent. No, The Edge Vent was designed to shed water at these roof pitches. Any water will be traveling from the peak of the roof all the way down to the edge of the roof with increased speed and volume. Thus, the water should safely clear The Edge Vent and the roof. The Edge Vent was designed so that when installed on a minimum pitch 3/12 roof the roof would still maintain an angle of decent towards the bottom edge of the roof. When installed on a 3/12 pitch, it can be deceiving because the angle is not very steep; only 2-3 degrees and may look like a pool area. It rapidly transitions back to 14 degrees.  - [Metal Roofing](https://help.gibraltarbuildingproducts.com/en/knowledge/metal-roofing?hsLang=en#main-content) - [Metal Roofing](https://help.gibraltarbuildingproducts.com/en/knowledge/metal-roofing?hsLang=en#metal-roofing) -
