Roofing Inspections 101: Inspecting Underlayment

Roofing elements must all work together in order to protect your and loved ones. When installing a new roof or replacing an old roof, it’s important to know what materials will do the best job for your home. At First Out Roofing in Denton, Texas we want to make sure you get quality materials and proper installation.

All about Roofing Underlayment

Roofing underlayment options are designed to meet the requirements of homes located in various climates. It’s important to select an underlayment that will work well in your area. The type of roof you are having installed also plays a role in helping you select an underlayment. It’s a good idea to speak with local professionals to ensure that the type of underlayment that is used on your home will be effective for both your roof type and climate.

Choosing the correct underlayment is important because it adds another layer of water protection to your roof. Most roofing materials are only water resistant, not waterproof. The underlayment is a membrane that helps protect your home from moisture. It is another layer of protection that is installed below the other roofing materials. This secondary barrier can be either water resistant or waterproof. Waterproof underlayment is typically used on the most vulnerable spots of your roof. This includes low sloping sections of roof and around penetrations. Most often, depending on your climate, water resistant underlayment can be safely used everywhere else.

Underlayment also provides temporary protection of the roof deck and home before the installation is complete. Roof covering material is usually installed as quickly as possible. However, setbacks can delay a full installation. The underlayment will provide temporary protection during this time. Underlayment also helps protect the roof decking from the chemicals that may seep down from shingles or other roof covering materials. This added layer of protection helps to extend the life of your roofing system. In addition to protecting your home from moisture, underlayment can also help increase fire resistance.

Things to Consider When Comparing Underlayment

There are a number of factors that you should consider when choosing which type of underlayment is right for your home. Underlayments are created for hot and cold dry climates as well as hot and cold humid climates. It’s important that you select the type of underlayment that is designed for your climate. Choosing the wrong underlayment can lead to roof failure.

It’s also important to consider the type of roof that you have. The runoff rate of moisture on your roof will depend on both the pitch and style of roofing. You also should think about any design features which have the potential to trap runoff water. The type of roofing material used can also impact which type of underlayment you need. Different types area available for use with different roof covering options. Some types of underlayment are not compatible with certain roofing materials.

If you’re unsure about which type of underlayment to select, check with a roofing expert such as those at First Out Roofing. We will gladly point you in the right direction to make sure that your home has the best protection available.

Inspecting Underlayment Installation

Choosing the correct underlayment is extremely important. Ensuring the proper installation of underlayment is also important. Installation methods vary depending on the type of underlayment used, along with the pitch of the roof. Some types of underlayment are self-adhering while others require the use of fasteners.

Unfortunately, those types of underlayment that require fasteners are at a disadvantage. This is because the fasteners make small holes that have the potential to allow moisture through. The most common type of fastener used in underlayment installation are staples. However, in areas with high winds and with synthetic underlayment then it’s more common to fasten them using plastic caps. Plastic caps are essentially nails with plastic gaskets. The gaskets help protect the puncture hole against moisture. In high wind areas, use plastic caps to provide additional protection against missing or damaged roofing.

If you live in an area that has regular ice buildup on the roofing eaves then you may also need an ice barrier underlayment. An ice barrier helps prevent melt water from backing up under your shingles or other roofing materials. When ice forms over the cooler eaves of your home then it prevents the melt water from running off the eave. This water can back up under the shingles and cause problems. An ice barrier is a self-sealing, waterproof, self-adhering underlayment that provides additional protection against ice dams. Ice barrier installation should begin at the lower edge of the roof and continue at least 24 inches beyond the inside of the exterior wall for adequate coverage.

Underlayment is an important part of your roofing system. Choose the correct type of underlayment and ensure proper installation. These two things can help extend the life of your roof and minimize potential damages.
