The Importance of Roof and Attic Ventilation

Your roof is usually the last thing on your mind, let alone attic ventilation. Yet every so often, it is one of the most crucial components of making a house comfortable. Ventilation is the flow of air through a system of intake and exhaust. This greatly determines the comfort and well-being of your family. After all, you definitely need clean air to breathe.

A well-ventilated attic prolongs your roof’s lifespan, is energy efficient, and cost-effective. Sadly, this is often not the case for most American houses. It’s one of the things that is simply taken for granted.

What You Need To Know About Attic Ventilation

Attic ventilation plays an important role in making sure the air in your attic flows properly. This way, it prevents musty air stagnation. To put it simply, ventilation allows outside air to pass in and out of your attic. Through this process, it removes excess moisture and heat from your attic. 

In a technical perspective, the air enters through your eaves and soffits, and is exhausted through the ridge cap or vent of your roof. Thus creating the right amount of air balance in your attic, thereby keeping your home comfortable.

But most roofs are poorly ventilated. Most people don’t know how much roof and attic ventilation they need, let alone what type they need to get. The FHA (Federal Housing Administration) recommends that for every 1 square foot of attic exhaust (both intake and exhaust), your attic space should have 300 square feet. 

Lack of ventilation is one of the major causes of a lot of roof damage. If you live in areas with temperature extremes of heat and cool climates, you need to prioritize taking extra care of this part of your house. If neglected, it can severely take a toll on your electricity bills and lead to costly roof repairs or replacement.

Here are a few problems you will encounter with poor ventilation:

  • Without proper air circulation retained heat happens. The sun’s rays produce extreme heat inside your attic. Heat transfers itself through your attic’s floor, warming up your house’s rooms. This is where your air conditioner works double time to keep your rooms cool thereby increasing your energy bills.

  • Heat expands and always looks for ways to escape, so not only does it go down, it also tries to go up. This will result in overheating your roof shingles, causing them to have a shorter lifespan.

  • This same extreme heat will warp your walls and anything made of wood. Most doors and window frames are made of wood, so you may wonder why you cannot properly close or open them during hot weather. This can also cause additional damage to your paint and wallpaper.

  • During the winter season, it does the opposite. Lack of proper attic ventilation during the cold months can cause condensation inside your attic. This happens when heat from cooking food, hot showers, or heaters inside your house meets the cold air in your attic. This creates and retains moisture that will lead to the growth of mold and mildew. Moisture also rots the wood panel or flooring of your attic

Having the right amount of air circulation in your attic can have a number of benefits. It extends the roof’s lifespan, manages indoor temperatures, prevents costly repairs, and reduces energy costs. You can thank yourself later in the year when you realize you didn’t encounter any problems because you prioritized the proper maintenance of your roof ventilation.
