There are a lot of different factors to consider when it comes to the quality and longevity of a roof system. For example, proper installation and the use of high-quality shingles will help protect against damage and prevent the need for repairs. One aspect that is often overlooked, however, is ventilation. A roof needs to have proper ventilation or else it will become vulnerable to all sorts of issues, resulting in a lifespan that is shorter than expected.
If you don’t have proper roof ventilation, the airflow in your attic will be restricted or even non-existent. This is because hot air will become trapped inside of your attic with nowhere to go, which can result in the buildup of excessive moisture. There are two main ways that you can create airflow through your attic. You can install mechanical ventilation, which requires a power source, or you can install natural ventilation, which makes use of the stack effect and wind effect to circulate the air naturally.
The stack effect is the process by which hot air rises and creates high pressure in the attic. For that hot air to escape out of the house through exhaust vents, cool, lower pressure air must replace it, which is done through the wind effect. The wind effect occurs when wind blows against the outside of the roof. With proper intake ventilation, cool air will enter into the attic, while hot air from the stack effect will exit, creating a natural airflow that results in a properly ventilated attic.
Proper roof ventilation is a must in order to ensure proper airflow through your attic. Without proper ventilation, your home will likely experience the following issues:
The following are a few signs that indicate your roof could use better ventilation:
Good ventilation is necessary to keep your roof in good condition. The better the ventilation is, the more likely your roof is to last for a long time.
