If your home has an attic, chances are you don’t pay much attention to it – they tend to be places we put things we don’t need, but don’t want to get rid of yet. Because of this, homeowners almost never go up there and don’t consider their attic’s air circulation a key part of maintaining the health of their home. HoweverUnderstandably, roof ventilation is a critical part of attic health and total whole home ventilation, and today we’re going to take a look at the top reasons why.
1. Extreme Heat
It’s common knowledge that your attic heats up in summer. Many homeowners assume this is a good thing – after all, it’s water damage that most people think of as the main hazard for roofing. While it’s true there’s less chance of water damage in a hot attic, the heat itself shouldn’t be underestimated. Stagnant air in your attic is capable of reaching temperatures hot enough to warp rafters. You can imagine that many seasons of this sort of stress can significantly weaken the frame of your roof over time, leading to costly replacements down the line.
It’s also worth considering the heat from the perspective of health and comfort. Your roof acts like a warm blanket or hat. As heat rises, it gets trapped in your roof. This can suffocate the lower portion of the home, leading to a house that is uncomfortably hot. Roof ventilation keeps the air up there cooler, helping keep your whole house cooler. After all, just like you wouldn’t wear a woollen beanie on a hot day, your roof needs to the chance to air out!
Depending on your roof’s construction, some attics are more sealed than others, resulting in minimal airflow. Unventilated attics are the perfect place for mould to grow, leading to the classic nightmare scenario of suddenly discovering a large infestation. After all, the last thing you want to discover is a lot of winter clothes stored in your attic damaged by mould. Mould and mildew tend to grow unchecked in attics because homeowners don’t frequent them, meaning they never even have the chance to notice damage before it’s too late. Roof ventilation – like a solar star roof fan - can play a critical role in keeping the attic space dry.
3. Damaged Insulation
Finally, the last major reason to ventilate your attic is to protect your insulation. Both heat and moisture can be absorbed by your roof insulation, damaging it in the process. This degrades your homes energy efficiency, which can lead to an increase in your power bills. Attic ventilation helps avoid this problem by keeping the climate ideal for insulation, ensuring it can maintain a comfortable, economic environment in the spaces you actively live in.
