A ridge vent is a ventilation system that runs across the peak of the roof, allowing for warm air release while keeping the elements out through internal weather filters. These ridge vents are said to be one of the most efficient forms of air ventilation and are also known for being aesthetically accommodating.
Because the vents do not protrude from the roof, they are said to be a more aesthetically pleasing option than the turbine vent. Although these vents are at the peak of the roof, heavy snow fall can cover them easily due to the vent being relatively close to the roof itself, defeating the purpose of the system. High winds can drive debris underneath the system as well, requiring circumstantial maintenance.
Despite the ridge ventilation being close to the roof, the ventilation is set at the peak of the roof, allowing for the most efficient ventilation of all of the air in the attic, as opposed to other ventilation options, which are less efficient at the ventilation of all the air. Though both the turbine and ridge vents are viable options for roof ventilation, they have their own advantages and disadvantages that still make the choice a personal decision.
