Often, homeowners only pay attention to the visible parts of their roofs. While not visible from the ground, underlayment plays a significant role in the longevity of residential roofing systems. This component is also vital to your home’s protection against the elements.
A local roofing company shares the importance of underlayment.
The water-resistant material installed on the decking before attaching shingles is the underlayment. It adds an extra layer of protection against leaks and weather-related damage. Synthetic, asphalt-saturated felt and rubberized asphalt are the three main types of roofing underlayment.
Synthetic underlayment features a base mat saturated in asphalt and fiberglass for added strength. Over a decade ago, asphalt-saturated felt was the most popular underlayment option. Your roofer might recommend this option if you have a steep-sloped roofing system but not if you have a flat one.
Increased Protection Against Water Damage
Heavy rains and snow can cause water to infiltrate and accumulate beneath shingles. Excessive moisture can lead to leaks, rot and mold growth. When shingles can’t offer protection against these issues, the underlayment is there to prevent them.
Helpful for Fire Prevention
Fires are among the most devastating incidents that can happen to a building. Underlayment can help protect your property against fire. An underlayment that is compatible with your shingles and meets industry standards and local building codes can help you achieve a Class A fire rating.
Added Weather Protection
During an extreme weather event, shingles can be torn from the roof. When this happens, water can travel to the materials below. In such instances, you can count on your underlayment to prevent rain, snow and ice from infiltrating the decking. Underlayment will protect your roof from the elements until necessary repairs have been made.
