Roof ventilation refers to the networked system of ducts and vents located in your attic that allows air to circulate and flow through. While most homeowners don’t pay too much attention to their home’s ventilation unless something goes wrong, prudent people will keep a close eye on their home’s ventilation to ensure any problems are caught early and that it’s set up to help their entire roof last as long as possible.
In this post, we’ll explore how proper roof ventilation can extend your roof’s lifespan and give you a few pointers to help ensure your ventilation functions optimally.
Let’s dive right in.
How Ventilation Works in a House
Most residential roof types come with ridge vents (along the top meeting point of the roof slopes) and soffit vents (running under the eaves). These are screened, open roof parts that allow air to move through an attic and out at its top.
As per the laws of physics, warm air will rise because it is less dense than colder air, which is why the warm air in your home will eventually rise up and out through your attic. Cooler air will, in turn, be sucked into your home to replace the escaping air through the soffit vents.
This circulatory cycle keeps the air in your attic at a balanced temperature with the outside world. This is why insulating your attic is important – attic temperatures are essentially outdoor. The critical importance of circulation is how it benefits your home’s general condition and your roof in particular, as we’re about to explore.
Benefits of Proper Roof Ventilation
The positive effects of proper ventilation include:
Improved Indoor Air Quality
While the insulation in your attic might help keep the cold and heat out, plenty of air will percolate through it and into the air circulating in your living areas. Proper ventilation can help keep pollutants, allergens, and other unwanted airborne contaminants from gaining access to you and your loved ones. This will keep all of you safe from allergies and respiratory conditions.
During the summer, warm air accumulates and becomes trapped in improperly ventilated attics. The result will be an increased burden on your air conditioning systems, leading to higher energy costs.
Conversely, during the winter, ice dams may form on your roof when warm air in your attic causes the ice on your roof to thaw and refreeze on the colder outer edges of the roof itself. These dams may lead to extensive water damage to your roof and home, but all this can be avoided by adequately ventilating your roof.
Prevention of Moisture Buildup and Potential Damage
Mildew, mold, and rot are some of the most telling and destructive signs of poor roof ventilation. These household problems come about chiefly due to moisture in your home. Some moisture will be released into the air whenever we take a hot shower, cook food, or perform water-related activities indoors.
Unless your home is properly ventilated, this moisture can accumulate in your attic, damaging your home’s structural components, roof deck, and insulation, aside from the disorders mentioned earlier. By ensuring that our homes are properly ventilated, we can evade the often costly damage to our homes that comes with moisture buildup.
Extended Roof Life
Aside from extending your roof’s lifespan in the ways mentioned so far, having a proper ventilation system will keep it functional and effective by mitigating the effects of heat buildup. When your attic temperatures heat up due to poor ventilation, the shingles on top will deteriorate much faster, leading to premature roof failure. Proper roof ventilation will prevent this eventuality, giving your roof an extended lease on life.
Proper roof ventilation is an essential part of homeownership for two main reasons. First, it will help keep you and your loved ones healthy and safe from potential respiratory illnesses and allergies.
Second is the fact that it will extend the lifespan of your roof and protect your home’s structural integrity. As a responsible homeowner, you should have your roof inspected at least once yearly by a professional roofing outfit that can identify potential trouble areas and provide the appropriate solutions.
