The Importance of Attic and Crawlspace Ventilation
Ventilation provides air circulation crucial to protecting your roof and other structural areas of your home. The attic and crawlspace are two of the most important areas for air to flow freely from the ground to the roof. However, these areas can get easily overlooked because we rarely check the attic or crawlspace for any problems. With the proper installment of vents in your attic and crawlspace, you can guard against the buildup of excessive moisture that can lead to damaging mold growth, unhealthy air, and other hazards. The following are specific reasons why attic and crawlspace ventilation are vital.
Protect against water damage—Vents in the attic and crawlspace are important to protect against the damage that water accumulation can bring to your roof, flooring, drywall, and insulation. Crawlspace ventilation is key to preventing moisture buildup from the soil, while intake and exhaust ducts in the attic ensure the roof will be safeguarded against the ravages of concentrated pockets of hot and cold temperatures. For instance, rooftop snow and ice become more manageable. With proper circulation, there is even melting, so there won’t be an excess of water run-off to damage your gutters, downspouts, and shingles if the water refreezes. This occurrence, called ice damming, can be prevented with proper air circulation.
Energy efficiency—Vents prevent the air from stagnating and pooling in one area. When air is enabled to flow freely, there is no burden on your heating and cooling system to work hard to control the indoor climate. Ventilation can help you cut costs in wasted energy, so you’re not paying more than you need to heat and cool your home.
Allergy and dust elimination—With vents installed to facilitate the efficient entrance and exit of airflow, dust, airborne pathogens, and other impurities are filtered out to ensure clearer and healthier indoor air.
Control infestations—When the accumulation of moisture is kept at a minimum, so too will mold, mildew, rodents, and insects that can warp and eat away at flooring, walls, and insulation.
Oxygen for gas—Gas appliances such as water heaters and furnaces need a proper flow of air to avoid the ignition of embers from a dry environment. Combustible materials such as cardboard boxes and clothing can be a fire hazard if embers are allowed to settle on them. Special ventilators, such as Turbine vents, are resistant to the entry of embers. A mesh screen can also be used to further prevent embers from entering. It also helps to cut down on the amount of storage you amass.
You can protect your home’s foundation, improve air quality, and ensure safety from hazards by checking for the absence of air ducts wherever you have square footage. To install vents, or if your existing vents need cleaning, repair, or replacement, hire a ventilation specialist to conduct an assessment. After inspection, they can advise you on the appropriate procedure.
