Your roofing system is composed of different parts supporting each other to preserve your home’s structural integrity. That is why as a homeowner, it’s essential to familiarize yourself with how each component works so you can detect issues early and have your contractor provide the necessary roof repair. This, in turn, will spare you from costly damage.

Underneath your roofing shingles lies the underlayment. Read on to learn about its key functions:

Secondary Weather Barrier

While it’s the job of roofing shingles or tiles to safeguard your home against the elements, they can’t hold up forever. They might sustain cracks, punctures, or get blown off by strong winds. This is where the roofing underlayment comes into play. It keeps excessive moisture from infiltrating the panels and flashings, thus stopping leaks, mold growth and other potential issues.

Protection Against Condensation

Condensation is a common roofing problem, which, if left neglected, can cause serious damage in the long run. This happens when the roof radiates heat and meets the colder temperature of the outside air, forming moisture. The moisture then soaks into the roofing materials, making them vulnerable to rot, mold and more.

Roofing underlayment can minimize or prevent condensation on the underside of the roof panel. To further avoid this issue, our roof repair experts also ensure proper ventilation in your attic space.

Fire Resistance

Most roofing underlayments are fire-resistant, which can help mitigate fire spread and penetration. This is especially important for homes in heavily populated areas or near wildland areas. Roofing underlayments come in different fire resistance ratings, however, so make sure to choose Class A rated products.
