Some humidity is important to home comfort, especially during winter. But too much vapor, combined with fumes from synthetic materials, cleansers, household chemicals and pesticides can make the air in a house not just uncomfortable but toxic as well. Fortunately Big Ike’s Roofing Company can solve this problem with ventilation.
Why is Ventilation Important in Homes & Buildings?
Houses need to breathe by drawing in fresh air and exhausting stale air. Opening doors and windows encourages ventilation but wastes heating and cooling energy and costs residents more money. Big Ike’s Roofing Company can install the proper types and combinations of vents and fans in unoccupied areas of the house, such as the attic and crawlspace, as well as venting specific areas of the home interior with bathroom fans, kitchen range hoods and whole house fans. There are two parts to ventilation – intake vents that draw in fresh air and exhaust vents that exhaust stale air. Big Ike’s Roofing Company can do a thorough inspection and then make custom recommendations as the type and location of the vents best suited to your home or building.
Fresh Air Intake Vents
Intake vents draw in fresh air through eaves or soffits. Some of the types of intake vents include:
Soffit vent. If your home is a new construction project or you are replacing your eaves or soffits, we will likely recommend installing soffit vents, which are metal louvered frames that traverse the entire area of the soffit.
Eave vent. Eave vents are added to a house to improve attic ventilation. They are typically circular shaped vents that sit under the eaves, between the rafters, and run along two sides of the house.
Rafter vent. A rafter vent works in conjunction with intake and exhaust vents. Rafter vents keep attic insulation from blocking airflow; from soffit and eave vents to the upper exhaust vents.
Foundation vent. As you would expect, foundation vents are installed along the foundation of the home. These louvered metal vents allow air to circulate throughout a crawl space or basement to prevent dangerous moisture from building up beneath the house.
Roof & Wall Exhaust Vents
Exhaust vents help stale air flow out from the roof. Some of the types of exhaust vents include:
Ridge vent. A ridge vent extrudes from and covers a gap at the top of the roof. It is typically a louvered section of metal that runs the entire roof length. The louvers release stale air from the attic and prevent rain and other inclement weather from entering the house. Ridge vents are the most effective way to exhaust stale air from buildings.
Roof vent. The basic roof vent is a square shaped metal. Some roof vents have a fan controlled by a thermostat that helps to quickly expel hot air in the summer as well as a humidistat that helps exhaust moisture in the winter.
Turbine vent. A turbine vent is a type of roof vent that features contoured vanes that pull heat from the attic in the summer and moisture in the winter. They turn with even the faintest breeze. It should be noted that their raised profile is often more noticeable than that of a standard roof vent so you may want to have them installed on the back of the house if appearance is an issue.
Gable vent. Gable vents are louvered triangles or square vents that are installed at the ends of the attic, near the roof’s peak. They are the least-effective exhaust vent option, but are commonly found on older homes.
