Charlotte Roofing: Article About The Purpose Of Underlayment
Roofing underlayment is the layer of protection between your house and the roof. In most locations, underlayment is required in new construction due to the variety of protective benefits it confers. As a result, the underlayment material is usually the first thing that a roofer installs on the roof. Similar to roofing materials, the underlayment materials that you can use on your roof depends on a number of factors, such as the climate. A licensed Charlotte roofing contractor can help you to choose the right underlayment materials for your house.
The first purpose of the underlayment is to provide temporary protection of your home's roof deck before the installation of the roof. Construction problems and other unforeseen obstacles can delay the installation of your roof. Under such circumstances, the underlayment is the only thing protecting the roof deck from harsh weather, such as heavy precipitation and high winds. Additionally, the underlayment also provides protection when repairing or replacing an old roof.
Contrary to popular belief, most roofing materials are not completely waterproof, but only water-resistant. The underlayment adds an extra barrier of protection against leaks. Unlike water-resistant roofing materials, the underlayment's waterproof materials prevent water and water vapor from passing through the roof deck into your home. If you have a metal roof, the extra underlayment barrier may not be necessary to prevent moisture from entering your home through the roof.

However, if you have a wood shingle roof, a waterproof underlayment is a necessity because both water and water vapor may pass through compromised wood shingles.
The right underlayment can increase your roof's life expectancy. Depending on your roof's materials, underlayment can act as a barrier to cold weather, repel hot air and stop leaks from reaching the roof deck. These properties decrease the strain on your roof, which increases its utility and prolongs its life expectancy.
Unless you have a metal or metal alloy roof, it is highly possible that it is vulnerable to fire. There are special underlayment materials that are designed to resist fire, which increases a roof's fire-resistant properties. For example, some roofing materials -- such as wood shingles -- are particularly vulnerable to fire. A fire-resistant underlayment can decrease the odds that a fire started on a wood roof will spread to the rest of the house.
In the past, roofing underlayment material was primarily asphalt-saturated building paper. However, it is now possible to get many different grades and styles of underlayment materials, including synthetic and organic materials.
