Breathable Underlayment Is Important For Your New Roof
Homeowners install new roofs with the goal of superior, long-lasting roof protection in mind. If the installation of your new roof does not involve the addition of a breathable underlayment, you probably won't get the experience you expected.
Moisture retention is one of the greatest threats a roof will face. If any level of moisture can build up under the roof, it's only a matter of time before rotting within the sublayers of the roof occurs. The rotting will damage and weaken the materials, and ultimately open the door to water penetration within your home, which will damage the insulation and other internal structures within the attic.
With breathable underlayment, moisture doesn't get trapped under the roof, which greatly reduces the likelihood of the above scenario occurring. As a result, you have the luxury of having a roof that lasts considerably longer than a roof without this type of protection, which means lower replacement costs going forward.
It does not matter what the local climate is like -- any roof will experience a cooling-heating cycle. For example, the temperature of the roof will drop significantly during the night hours when the air temperature is cooler, and the roof will heat when the sun rises and the temperature increases. This hot-and-cold cycle will typically lead to condensation.
It's important to remember that condensation is moisture, so any roof that experiences heavy condensation can also experience considerable moisture damage. With breathable underlayment, the rate at which a roof experiences condensation is reduced considerably. With less condensation, there also comes along a lower risk of moisture damage, which means the roof will perform better overall.
Every roof needs to breathe in order to prevent considerable moisture damage and even damage within the interior spaces of a home, such as an attic. However, with a roofing system that does not include an underlayment, the only way to get this ventilation is through the installation of a ventilation system.
Breathable underlayment takes care of this area and, when included, eliminates the need for a ventilation system to support the roof. When you compare the cost of a ventilation system to breathable underlayment, the cost of the underlayment is far lower. As a result, you get roof protection for a fraction of the cost with this option.
