Note: In this case, you must remember that you are going with the second best and not the best solution. Given below are soffit vent alternatives that will work with ridge vents What if you have no soffits vents?īut what if your roof doesn’t have an overhang for soffit vents? It is still possible to vent the attic with ridge vents. However, it is best to keep the ridge and soffit vents open during the winter than not. The hot air inside the house can seep through the ceiling into the attic and escape, thus increasing utility bills. One downside of doing this is that it will lead to heat loss if the attic is not insulated properly from the living areas of the house. Air circulation also helps to avoid mold growth during that season. Having air circulation in the attic during winter will prevent it from heating up and forming ice dams. Soffit and ridge vents are useful in the winter season as well. Blockages will lead to a hot attic, and mildew and mold forming on the rafters as well as on the insulation of the attic. The holes above the soffit vent should be big enough and unobstructed to allow free air passage. (Readmore about this on Can you paint soffit vents). Care should be taken not to obstruct the vent holes if you decide to paint the soffits. Soffit vents can be neglected and sometimes covered with a layer or more of paint that blocks the airflow. Working of a ridge soffit ventilation system in an atticįor this system to work well, there must be no blockages preventing the flow of air from the soffit vents to the ridge vents. The system works marvelously to keep the air temperature inside the attic close to the ambient temperature, and thereby, the attic is kept cooler. This air movement takes place along the path of least resistance, and the air entering the soffits will move between the shingles/water barrier/plywood and the ceiling insulation of the attic ceiling until they are exhausted through the ridge vent. The ridge vent creates a draft, and the negative pressure it creates pulls air through the soffits. Under normal circumstances, a ridge vent works in a similar way to a chimney. In this arrangement, thanks to wind and natural convection, ambient air enters the attic through the soffit vents at the bottom and is exhausted through the ridge vents at the top. Ridge vents are installed on the top of the roof. Soffit vents, if you don’t already know, are installed at the soffits of the house, which is the lower portion of the attic. Working of Ridge-Soffit attic ventilationįor soffit-ridge attic ventilation, the soffit vents act as the fresh air inlet and the ridge vents as the exhaust vents.
