The roof on your building is one of the most important parts because the roof protects the inside of the building. You may not realize though that proper roof ventilation is also vital for commercial buildings. If you are getting ready to replace the roof on your building, you may want to talk to your roofer about extra steps you can take to provide your building and roof with the proper amount of ventilation.
Why Is Ventilation Important?
Ventilation is important for all types of buildings because it improves the airflow between the building and the outdoors. Airflow is necessary for a number of reasons, including:
- Keeps the attic space temperature regulated in the summer and winter – When air is flowing properly, it will keep an attic cooler in the summer and warmer during the winter months. This can directly affect the temperature inside a building and can help control heating and cooling costs.
- Helps a roof stay dryer in the winter – If the attic space stays warmer in the winter, it will help melt the snow on the roof.
- Reduces the amount of moisture on a roof – Keeping snow off the roof in the winter is important because moisture damages roofing materials. Your roof may last longer if it has a sufficient amount of ventilation.
The goal of ventilation is ultimately to protect the roof and the building; however, proper ventilation is also important for energy-efficiency inside a building. All types of roofs need ventilation; however, installing a ventilation system on a flat roof tends to pose challenges because of the way a flat roof is designed.
How Is This Accomplished?
With a pitched roof, a roofing contractor will install several different vents on the roof itself, and the vents will be connected to the attic space. This allows the air to flow to and from the attic, but this process tends to work better if there is an attic fan installed as well.
When an attic fan is running, it will continuously be pulling and pushing air from the attic. As air is pushed out, fresh air is pulled in. Because of the purpose of roof ventilation, it is also vital to make sure that there is enough insulation in the attic. Insulation will help control the temperature in the attic and in your building.
With flat roofs, this job is harder because there is not usually an attic. If there is an attic, the space is very limited. Because of this, installing ventilation for a flat roof is tricky, but there are options. One option is to have the roofers create a gap between the top of the building and the roof. This will require using additional building supplies and may cost more, but it will offer protection for your new roof.
Your roofer may also be able to install some vents on the roof, but the vents may have to be connected inside your actual building. When this option is used, the roofers must install the vents properly and waterproof them to make sure they do not leak.
As these renovations are being conducted, you may also want to talk to the roofers about other options you have to protect your building from water. They may be able to install a better gutter system for you, or a drainage system on your roof. Any of these additional steps may extend the life of your roof and should help prevent water problems from occurring.
