The Importance of Proper Roof Ventilation from Your Benton Harbor Roofing Contractor
A critical factor in the performance and lifecycle of a home’s roof is its ability to vent. The correct amount of attic ventilation extends the life of a roof because it minimizes the temperature differential between the attic and the air outside. This is important because an inefficient ventilation system can raise energy costs, damage roof system components, lead to the formation of ice dams, and ruin personal items stored in an attic. We know that improper ventilation can be a living nightmare for many homeowners.
Sealed and Secure
An effective air ventilation system controls attic moisture in the winter and hot air in the summer. For prime efficiency, all openings leading to the attic floor must be sealed. That list includes ceiling light fixtures, attic access doors and hatches, electrical wiring, plumbing pipes, exhaust fans, and chimney chases. If any of these are not properly sealed, warm moist air will travel from lower living spaces to the attic and cause damage when it condenses.
Whether your roof project is new construction or replacement of an existing roof, installation of the best ventilation system for your house is critical. The best ventilation system is one that effectively keeps the components of a roof assembly sealed and secure.
You, the homeowner, do not have to figure all of this out. That’s the job of your chosen roofing contractor. However, it will help you make the best choices if you have an understanding about the basics of roof ventilation.
A roof’s ventilation system should be engineered to allow consistent intake and exhaust airflow underneath the covering of the roof substrate. It needs slotted fastening holes that promote thermal movement through the vent passages which air flows through from the eave to the ridge. This keeps the entire roof system balanced by promoting the correct flow of air.
Proper venting should be a mix of 50% on the roof and 50% under the eaves or soffits. This distribution of venting will assure a proper flow of air in the attic space and minimize problems that occur in improperly vented attics. Experienced contractors are skilled in determining how variables interact and impact residential roof ventilation. They can assist you in determining the ideal airspace relative to your project’s ventilation needs.
