How do they put in a roof hip vent.

I don t like hip vents won t install them. I also don t like on the roof intake vents like the edge vent or smart vent though i have installed the edge vent last year. Cobra hip vent provides effective ventilation on hip roofs with little or no ridge area. A powered attic fan and install a ridge vent b ridge vent only and install.

Here are the three options presented. These holes will likely be installed closer to the ridge but manufacturer instructions should always be followed. It provides 9 sq. I can t see how they wouldn t let in a driving rain in a 40 mph wind.

In these cases there may be no option but to add multiple individual exit vent openings across the roof field. Putting them at mid roof or lower is ineffective. Typically a hip roof should have 1 power fan per 1500 square feet of roof to best exhaust ventilate the heat in the attic space. Of course this depends on the strength of the power fan.
