The Right Amount of Roof Ventilation in Indiana and Ohio

When it comes time to replace your roof you need a professional roofing contractor that will assess your roof ventilation and make sure the intake and exhaust are properly equalized. Higher energy bills, premature shingle aging, mold growth, interior damage, or ice damn build up can all be symptoms of poor ventilation. When you’re choosing a roofing contractor in the greater Richmond, Indiana area, make sure you are going with a qualified roofer who can balance your ventilation correctly.

How Ridge Vents Work. Every home needs ventilation to create a barrier between the difference in air temperatures inside the home and the outside atmosphere. Vents in the eaves, soffits, or fascia area of the roof are there to allow fresh make-up air into the attic space and allow exhaust air to leave the gable end, roof jack, wind turbines, ridge and exhaust vents. During the warm months, without ventilation your attic becomes excessively hot from trapped heat caused by the sun. In the colder months roof ventilation cools the air coming up from the home and reducing the amount of snow melt and resulting issues with ice runoff and ice damns.

Is Your Roof Venting Balanced? Determining if you’ve got the right amount of ventilation isn’t something you want to guesstimate. Proper roof ventilation is one square foot of net-free vent area for every 300 square feet of attic area – the 1/300 rule. In other words, once you’ve measured the total square footage of your attic or the length and width of the attic floor; there needs to be 1 square foot of ventilation for every 300 square feet of attic area. If you aren’t sure of either your measurements of your attic foot print, or the size of your current venting, call us for a free roof estimate or a free roof inspection.

Ventilation removes the hot air from your home, which prevents heat and moisture buildup, eliminates ice, and preserves the lifespan of your shingles. Air comes into your home through the intake vents or soffit vents located at the roof overhang (where the roof connects to the side of your home). The air will then flow out of the exhaust vents on your roof. The number of exhaust vents can be determined by the 1/300 rule. Together, the intake and exhaust vents provide the circulation needed to generate proper airflow.

An appropriate roofing ventilation system uses a combination of exhaust and intake vents to promote circulation. Eave and soffit vents are examples of intake roof vents. Mixing various types of exhaust vents on the same roof can disrupt the natural airflow that otherwise would allow the warm air to escape and ultimately prove counterproductive. The result would be a roof with hot and cool zones, which could cause different areas on the roof to age at different rates.
