Attic Ventilation Benefits
Energy – We are always looking for ways to cut corners with our energy bills and save money where we can. This means that proper air ventilation is needed. In the summertime, when the heat rises outside, we use our air conditioners to cool the house down. When we do this, we need a place for the hot air to escape to as the cool air fills the home. This is where your ventilation system comes into play. Once the hot air has somewhere to escape to, your A/C will not have to work as hard. This will in turn, lower your air conditioner costs.
Longer Roof Life – When it is freezing outside and it snows, you may start to see that there are icicles on your roof. The reason for this is because when snow lands on your roof, the heat from the attic (if it is unvented) will start to melt the snow and it will slide to the end of the roof. Once it is there, it will start to refreeze, hence, icicles. If your roof has the proper ventilation, the snow attic will not be as hot because the air will be able to escape and not build up, allowing the snow to sit on the roof and melt naturally, avoiding icicles from forming. Although they may be pretty, they can cause unnecessary weight to be added to the edge of your roof and can cause a lot of damage over time. When you have the right ventilation, it will take the stress off your roof and will actually cause it to last longer than ever before. This is important for metal roofing as well as it can get very hot.
Lower Your Indoor Temperature – When you have no attic ventilation, the heat in your home will rise. If it has nowhere to go, it will go upstairs and it will make your upstairs much hotter. This is important because we have all been to a house that you walk upstairs and it is so much hotter up there than downstairs. If the ventilation system was working properly, this would not be happening. If you are having fixture installation done, you can consider having the plumber check out your ventilation system as well to make sure that everything is working correctly.
