How to Increase Your Roof’s Lifespan

One of the biggest (and necessary) investments you need to make in your home is installing a new roof. Depending on the quality of the materials, installation, and maintenance, roofs can last anywhere from 12 to 50 plus years. However, an imperfect amount of roof ventilation (or none at all) can shorten the lifespan of a roof. Here’s how the proper ventilation can increase your roof’s lifespan.

Moisture Problems

In order to have an energy efficient home, you need to have a house that can efficiently lock air inside of the house. However, the lack of fresh air can cause indoor air quality problems. Yes, you can buy air filtration systems to filter the air in your home, but the moisture will still remain. Excess moisture can lead to condensation and future mold problems — which can be devastating to your roof and its ability to protect your home.

Roof Damage

When there is no roof ventilation, moisture in the attic will have nowhere to go so it will form as condensation on the plywood sheathing of the roof. Eventually, the plywood will expand, buckle, and become misshapen. Roof sheathing that is damaged like this will begin to crack under stress, not be able to effectively hold the roofing nails in place, and become damaged more easily during storms. Installing the adequate amount of roof ventilation will allow moisture to vent out of the roof and attic space.

High Temperatures

During the summer months, attic temperatures can reach up to 150 degrees while roof temperatures can hit over 180 degrees! To keep the temperatures from ever getting this high, an attic vent system will need to be installed. When warm air rises within the attic, it will pass through the exhaust and create a suction at the intake vents bringing in “cooler” air from the outside. The cooler your attic space is, the less damage your roof will sustain and the longer its lifespan will be.

Quality installation, materials, and maintenance can increase a roof’s lifespan, but don’t forget about something just as important — roof ventilation.
