Your roof is one of the most often taken for granted, yet extremely important elements of your home. It is typically out of our reach and requires infrequent maintenance so many homeowners are unaware of important areas that affect its longevity. Making sure that there is proper ventilation for your roof is one of the most important things that you can do to prolong the life of both your roof and the structure that it protects.
“Thermal Comfort” is a buzzword of modern home building and renovation. It is aimed at making the environment as perfect as possible when it comes to the temperature of the home. This is done in two major ways:
All this technology can lead to complications that can damage your home and make life miserable for you and your family.
With the airtight system of the modern home, things are entering the environment, but not leaving. This leads to a closed system and a home that cannot breathe. The buildup of evaporated water from activities such as cooking, cleaning, and breathing is the largest concern for such a home. This is water that cannot leave your closed system. If your home is suffering from humidity, condensation, allergies, or mold growth, you might have a home that needs ventilation.
An estimated 9 out of 10 homes don’t have a properly balanced attic ventilation system in place. As a result, the average roof lasts only 10 to 12 years, even though most roofing shingles are made to last 25 years or more. In fact, the number-one reason for premature roof failure is inadequate ventilation.
What most homeowners don’t realize is that without proper roof ventilation, most manufacturers’ shingle warranties are void. That means those same nine out of 10 homes may never have even had valid warranty protection on their roofs.
The unregulated and unintentional escape of air is air leakage. When air, especially hot air, is leaking out, your heating or cooling systems have to work that much harder. And that costs you money. Ventilation comes in two forms:
The largest form of indirect ventilation should be your roof.
Proper roof ventilation helps regulate the temperature inside your attic by pulling fresh air into the attic and pushing out heat and moisture. This in turn reduces the temperature difference between the air outside and in the attic, preventing damaging heat and moisture build-up.
One of the main reasons your roof needs proper ventilation is to make regulate the heat inside your attic. During summer, the temperature is going to be very hot regardless of the amount of ventilation that you have. If you lack the proper ventilation, however, the temperature could reach upwards of 160 degrees Fahrenheit. This heat is detrimental in a variety of ways.
When the temperature in your attic is poorly regulated, one of the main side effects is an increase in humidity. This moisture is much more dangerous than the heat itself. Humidity will condense on the interior and within the roof itself, leading to water damage and rot that might not be covered under your last roofing guarantee. If enough moisture builds, it can even seep into your walls and ceiling, resulting in extensive hidden water damage, mold growth and a very unpleasant musty odor.
Since the roof and attic are the main area for humidity to collect in a climate controlled home, it’s important to have airflow in the roof and a ventilation system to spread it around the home.
Although it may be tempting to install as many fans and vents as possible, there are also some dangers to over ventilating. Electric attic fans can pull too much air out of your attic. This can cause combustion gases from your water heater or furnace to be forced back into your home. Because of this, this type of ventilation is no longer recommended. Work with a professional to make sure that your roof has the perfect amount of ventilation.
As you can see, proper ventilation is a big factor in maintaining the longevity of your roof. Proper ventilation reduces chances of ice damming, lowers heating and cooling costs and keeps mold and mildew from forming.
There are two major points of ventilation: below the eaves and along the top-most point or ridge of the roof.
Permeable ventilator strips are installed beneath the eave. Permeable strips allow humidity to through. You can also ventilate using tile vents set at regular intervals. One ventilation set on either side of the attic can allow air to enter from one side and leave through the other, taking humidity and other environmental buildup with it. However, if you’ve got a crowded or cramped attic, it’s time to add a ridge vent.
Using a continuous ventilation strip, or ridge or tile vents, you can install a similar ventilation on the ridge of the attic and roof. The ridge is the topmost joint of the triangle. This ventilation allows hot, humid-laden air to leave through the roof. That draws in fresh air down at the eaves which allows for a continues flow of air.
Your roof plays an important role in the overall safety and life of your home. You should educate yourself about its care and maintenance. If you have a relatively new roof installed by a credible roofing company, then you most likely have proper ventilation. If your roof is older, or you are unsure who did the installation, it may be worth your while to have it looked at by a professional.
One way to test whether you have enough ventilation is to take the temperature of your attic on a hot day. If there is more than a 15-20 degree temperature difference over the outside temperature, then talk with a professional roofer about improving your roof’s ventilation.
