Residential roofing systems need proper ventilation to remain in good condition. The things you do daily – including cooking, showering and running your dishwasher – generate heat and moisture that can rise to your attic. With good airflow, warm, humid air will effortlessly escape the space, helping you save on roof repair costs.
Continue reading to find out what can happen if you don’t have proper attic ventilation.
Reduced Roof Lifespan
Too much heat and moisture can cause dry rot in the decking and speed up the deterioration of shingles and underlayment. You’ll know you have poor attic ventilation if you find an excessive amount of shingle granules in your attic and the ground. Shingle damage is also a common indication of the issue.
Mold and Mildew Growth
Increased humidity can encourage mold and mildew growth. Mold can create spores that circulate in your indoor air and affect your family’s health. They can cause allergies and trigger asthma attacks. Another thing mold can do is damage important items stored in your attic.
Residential roofing systems need sufficient ventilation to stay in good condition. When humid air fails to escape your attic, moisture will penetrate and build up in the decking. Over time, it will compromise the adhesives securing the material together, causing it to sag.
Poor attic ventilation can cause ice dams to form. The buildup of warm air in the attic causes snow to melt, which refreezes when they reach the colder areas of your roof. These ice formations can keep melted snow from shedding off your roof.
