Roofing Underlayment and the Role It Plays

Underlayment is one of the most vital roofing parts, as it allows your system to withstand almost anything Mother Nature brings. A water-resistant barrier installed directly to the roof deck and underneath the shingles, this roofing component helps protect against moisture damage. Without underlayment, problems like wood rot, mold growth, and degradation of materials can occur. 

Earl W. Johnston Roofing, LLC, the leading company for roof cleaning and replacement, explains further the important role of roofing underlayment.

• It helps repel water. Your shingles can end up trapping rain, snow, and other forms of moisture. If water doesn’t drain properly, it will create moisture damage, which will eventually result in leaks, rot, or mold formation. This is where the underlayment comes to play. If water does seep beneath the shingles, it helps water properly run off the roof instead of into your spaces.

• It serves as a barrier backup. Shingles are the first line of defense against extreme weather, but having an extra layer of protection doesn’t hurt. If a major storm tears a few shingles loose, the underlayment serves as another line of defense against the elements until you schedule a professional roof repair to fix the shingles.

• It helps maintain roof uniformity. Some roof decks don’t really sit perfectly straight. With a layer of underlayment installed, the roof gains a smooth, flat layer on which to place the shingles.

• It prevents wood resin stains. Resin can be produced from certain types of wood used in the construction of roof decks. Over time, this can stain and damage the shingles. Having an underlayment can prevent resin from compromising shingles.
