A roof ventilation system working properly will keep your roof cool and moisture free. This is a very important process, as a roof with poor ventilation can cost you a lot of money. The main problem with improper ventilation is an unhealthy buildup of moisture in the attic. This excess moisture can have damaging effects on your roof. In this blog, we’re going to provide you with some further information on the effects of improper ventilation.e
Mold & Mildew
A moist, warm environment is the perfect place for mold and mildew to flourish. They can end up causing health problems, if left to grow. People report asthma, headaches, fever and other symptoms as a result of the presence of mold and mildew. It is impossible to control the growth of these contaminants in a moist environment. The only way to rid your attic of this problem is to remove the moisture.
Roofing Structure Deterioration
A constantly moist and warm environment can cause the entire structure of the roof to deteriorate. This type of excessive moisture can cause the decking on your roof to sag. Moisture can also cause the adhesive holding the decking together to dissolve, making your roof unsafe. Improper ventilation can cause problems with your shingles, as well. Missing or cracked shingles will need replaced.
Frost & Ice Dams
If you have excessive moisture in your attic come winter, you may have frost forming. Once this frost melts, it can leak into your ceiling. This causes even further deterioration and water damage. An ice dam can form around the perimeter of your roof, where hot hair escapes and melts the snow. Once the snow is trapped there, it cools and hardens. This prevents any further precipitation from properly draining off the roof.
