Proper ventilation and insulation works hand in hand to keep your roofing system as effective as possible in providing protection and comfort to your homes. Find out more about the roles of ventilation and insulation in this article.

Ventilation

Proper ventilation is a very important aspect of the roof system. It determines the durability of your roofing. Without proper ventilation, moisture can accumulate under the roof and this can lead the roofing materials to rot and buckle. Furthermore, the role insulation is lost with rotten materials and holes in your roof system.

There are many sources of ventilation for your roof. The most common sources include ridge vents, louvers, and soffit vents. Did you know that many people cover these sources during winter? This is something that should be avoided. Never block off the louvers and vents because they maintain the proper flow of air. Without the right flow of air, you attract the growth of fungi because of the high moisture level. Hence, the right ventilation prevents the possible structural damage.

Aside from preventing structural damage, proper ventilation also reduces energy consumption and extends the life of the material. Ventilation is also the key to enhancing the level of comfort in the rooms below.

Insulation

Insulation is another important aspect of the roofing system. It works hand in hand with ventilation in providing comfort to the rooms below. The most common requirement for the proper insulation is a gap-free layer of insulation in the attic floor. This will protect the rooms below form heat loss or heat gain.

Another requirement is the vapor retarder. Installed under the layer of insulation, this will stop the rise of moisture into the attic area. This will reduce the level of moisture in the attic area.

Aside from the vapor retarder and layers of insulation, it is also important to provide an open space to allow the air to flow freely. In addition, there should be a minimum of 1 inch space between the sheathing of the roof and the gap-free layer of insulation.

Conclusion

In the end, the ventilation and the insulation are two aspects that your roofing contractor should make known to you. These requirements will greatly affect your comfort, protection, and the longevity of your roofing system. Make sure that these requirements above are followed. You can also consult with your contractor for suggestions. They may recommend certain solutions based on your location and other factors such as humidity and exposure to the sun.
