When you look at a house with a new roof you probably take a look at the color and design of the new shingles on the house, but do you notice the added vents on the roof? Do you even pay attention to the vents in your current roof? Many homeowners do not pay attention to attic ventilation because it might not seem important, but that can be a costly mistake. Proper attic ventilation helps protect the entire roof structure, including the shingles and the roof deck, and contributes to a more comfortable living environment inside the house.
A properly designed and installed attic ventilation system creates a continuous flow of air through the attic that helps reduce heat and moisture build-up. Attic ventilation is important year-round. In the summer, heat from the sun builds up into the attic and radiates into the living space. Your home can become uncomfortable, air conditioning usage increases and roof shingles and roof shingles can deteriorate prematurely. In the winter, moisture generated inside the home raises into the attic where it can condense and continue to the conditions that cause mold and mildew. Mold spores produce allergens that affect air quality. Moisture can cause wood rot and even structural damage, and if insulation gets wet it can lose its ability to insulate.
Lack of ventilation is also one of the main contributors to winter ice dams that cause extensive damage to homes every year, your attic should remain cool in the winter so that the snow on your roof melts slowly and evenly to help reduce the likelihood of ice damage. Ventilation systems should be designed to create a flow of air through the attic; cool fresh air enters the attic installed in the soffit or under eave and exits the attic near the peak of the roof through exhaust vents along the way the air moves heat and moisture out of the attic, the most efficient and effective exhaust vent is a ridge vent. Only ridge vents provide a constant flow of air along the entire horizontal ridge of the roof, with other exhaust vents some pockets or sections of the attic can be left unventilated. Ridge vents also win when it comes to aesthetic. Shingle over ridge vents are installed along the ridge and covered with cap shingles and the blend in with the roof so they can barely been seen from the ground.
Most professional roofing contractors use ridge vents, but there are different types of ridge vents, and some perform better than others.
