The roof system comprises different types of rooftop components that help the rooftop perform its functions against various weather elements. There are distinct layers of the roof system. Roof shingles are the visible layer but are not the only component. There is underlayment water and ice barrier insulation and ventilation.

All these work together to help the roof perform its job. Since these adhere to the roof deck, water and ice underlayment products create a barrier on the rooftop, which allows them to maintain the temperature and keep the moisture at bay. Read the article to learn more about the critical component of the rooftop system.

How to protect your roof from moisture? 

There are multiple purposes for the rooftop. The rooftop protects the house from the elements like snow and rain. Rain affects the rooftop’s surface and runs down the roof’s slope into the gutters. It is then directed away from the foundation through drains, downspouts, and rooftop snow then melts following a similar path.

Unfortunately, various situations may disrupt the flow of moisture, and standing moisture is not a good friend of the rooftop. Water that has pulled on the roof’s surface may cause multiple problems and make it very difficult for the shingles to be in place.

Understanding water and ice barriers

A practical solution for protecting the rooftop from moisture damage is water and ice barrier underlayment. These are put below the singles. Adhering directly to roof decking, the barrier is impermeable, which means that they will seal tightly to the roof around the nails and maintain the overall structure. Along with this, it will keep the moisture out.

Water and ice barrier provides added protection to the rooftop and may be utilized in multiple areas as follows:

  •    Valleys: The rooftop will have multiple valleys and peaks based on the architectural design. Since the valley is connected to water, these are vulnerable to the effect of water. Rain goes down the rooftop and gets collected in the valley before it flows into the gutter.


  •    Eaves: The edges of the rooftop are exposed. Winds may move the shingles, lifting these and letting the moisture in blocked drains, which may cause moisture backup.


  •    Roof penetration: when you cut into the roof’s decking, you offer an opening for moisture infiltration. Placing a water and ice barrier from Atlanta, GAaround skylights, chimneys, and vents will help seal the gaps around the vulnerable spots.


  •    Roof surface:Based on your location, it may make sense to utilize a waterproof barrier on the whole surface beneath the shingle. Losing the singles during storms and other weather conditions may have a tremendous effect on the rooftop. If you don’t want to endure these problems with the roof deck, you need to secure that against the elements by proper ceilings.

You can prevent ice and snow dams by going for attic ventilation and attic insulation. With the help of proper professionals, you can make provisions for the apt sealing of the rooftop that will keep heat and water at bay.
