Underlayment is material that goes on top of roof decking and below roofing material such as asphalt shingles, slate and wooden shakes. Underlayment was once made of asphalt saturated recycled rags and had a fuzzy felt feel to it. Today, underlayment is readily available in new and improved felt as well as synthetic variants. Many homeowners are unaware about the importance of underlayment, but it serves a vital role in every roof system. Bergen County roofing professionals are always available to answer questions regarding underlayment or any other roofing material.

For a variety of reasons, underlayment should always be installed under roof coverings. Most importantly, it serves as a final protective barrier against moisture entering the home through the roof deck. Asphalt shingle and other similar roof systems are actually designed to shed water from above, and they can leak when water comes from other directions as a result of wind driven rain, clogged gutters or ice dams. Although standard types of underlayment are not completely waterproof, a layer of felt or synthetic material does protect the otherwise bare wood roof decking from these types of water infiltration.

Without underlayment, this water can rot the wood decking, cause mold and mildew in the attic and eventually lead to significant structural damage to the home and its contents.

Underlayment is often required under products warranties and building codes. All manufacturers of roofing products offer extended warranties with the purchase of their products, but many of these warranties become void if underlayment is not used. Homeowners should check with their local building department for codes related to the use of underlayment in their city.

Additionally, roofing underlayment actually does several things to assist in the installation process. It provides a temporary barrier against the elements to protect wood decking while installation of the roof is ongoing. Many types of underlayment also have guide lines built into them. If installed correctly these lines can ensure the roof covering is correctly aligned and presents a perfectly straight appearance when finished. Professional roofers also appreciate that synthetic underlayment comes in white. White material does not get nearly as hot as black in direct sunlight and can help a roof stay cool. Synthetic underlayment is also sold with a slightly sticky texture to help prevent slips and falls on the roof.

Homeowners are cautioned to beware of a roof replacement bid that does not include underlayment. It simply provides too many benefits and should not be left out during a roof installation.
