This will use more energy and make your air conditioner work harder which will increase your summer utility bill. Attic ventilation keeps your house cooler in summer and it prevents moisture from building up in winter and ruining your roof framing and insulation. Typically you would have a gable vent on each end of the attic. When the attic becomes part of the home to be heated and cooled open wall gable vents and roof vents are no longer feasible but the underside of the roof the sheathing and rafters can still.

But if you ve got an unfinished attic giving it proper insulation is one of the simplest ways to keep a lid on your heating bill this season. One great alternative to a soffit ventilation system is to install an intake vent right at the lower edge of the roof. If the attic ventilation system is not a balanced combination of intake vents installed in the soffit under eave or at the roof s bottom edge and exhaust vents installed at or near the roof s peak the attic ventilation system will not be efficient and effective.

On the principle that hot air rises the accumulated heat and moisture would rise to the attic and out the roof vents. The venting drip edge seems to be the easiest and most common way to go. If your attic has inadequate ventilation it can act like a heat trap and lead to premature shingle aging warp wood sheathing lead to mold issues and increase your hvac costs. Without adequate ventilation moisture rises with the hot air and forms condensation on the inside of the roof deck.

However if your attic has blocked soffit vents and is not well sealed from the rest of the house attic fans will suck cool conditioned air up out of the house and into the attic. Poor insulation is usually the culprit although if you enter the attic on sunny winter day your attic space can be warmed by the sun more than your furnace.
