Your roof may look tough on the surface, but your exterior roofing alone isn’t what makes it capable of withstanding the elements. Beneath the asphalt shingles or metal panels is another layer of protection called the underlayment. Adamson Roofing Company, one of the top reroofing contractors in the area, explains everything you need to know about this important roofing component below.
A Waterproof Barrier for Your Roof
Underlayment is a water-resistant material sandwiched between the roof covering and roof deck or sheathing. Its primary purpose is to stop moisture from penetrating the structures that hold the entire roofing system in place. We all know about the damaging effects of water, not just to the roof but also to the entire house, which is why expert roofers make sure to apply the right underlayment before installing the roof covering.
Because it comes first before the residential roofing pros begin installing asphalt shingles or metal panels, underlayment also serves as temporary protection for the entire home. It may not be as effective a protective measure as the finished roof, but the component will suffice should there be a delay in the installation because of rain or snow.
Types of Underlayment
There are various underlayment materials used in roofing. The most common is asphalt-saturated felt, which was the go-to material of choice for many roofers before synthetic alternatives slowly rose to prominence. It’s water-resistant, but not as much as the newer materials.
Rubberized asphalt is also a widely-used underlayment material known for its tremendous waterproofing qualities. It combines rubber polymers with high-density asphalt to give roofing systems maximum protection against water damage.
