Proper Roof Ventilation’s Importance from Your Grand Rapids Roofer, Sherriff-Goslin
A key factor in your roof’s performance and lifespan is proper roof ventilation as it extends the life of your roof by minimizing the difference in temperature between the attic and the outside air. If your roof has an inefficient ventilation system you could have high energy costs, damaged roof system components, and formation of ice dams. In this post, your Grand Rapids roofer, Sherriff-Goslin, will take a closer look at the importance of proper roof ventilation.
Controlling attic moisture in the winter and hot air in the summer is crucial. 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.
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 half on the roof and half 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.
Fortunately, you do not have to figure all of this out. That’s the job of your Grand Rapids roofer, Sherriff-Goslin. However, it will help you make the best choices if you have an understanding about the basics of roof ventilation.
