In addition to metal roofing becoming an increasingly popular choice, metal underlayment is an excellent way to provide extra protection to the roof because of its durability, fire resistant capabilities, and ability to shield the roof from wind damage. However, in order for metal underlayment to be effective, it must be installed in a specific way, and it typically requires specialized tools. Dutchess County roofing experts who are familiar with installing metal roofing underlayment understand that the process might resemble the same method by which shingles or other common roofing materials are installed. However, the installation of an additional layer might also be required, depending on the specific layout of the roof.

Metal roofing underlayment is an ideal choice for homeowners who live in areas that experience harsh winter weather, such as New York. Ice dams can easily develop whenever warm air from the attic area rises to the roof and melts the snow that has accumulated on the surface of the roof, and when the melted water reaches the eaves, it refreezes and can damage the shingles. The water often leaks into the interior of the home and causes major damage. Whenever roofing contractors install metal underlayment, they can also add an additional layer of ice and water shield in order to offer maximum protection from the development of ice dams.

The Roofing experts at Precision Roofing of Dutchess County NY can answer your questions about roof repair or residential roofing.

The shield should ideally extend about two feet from the top edges of the roof overhang in order to function properly, and a second strip of shield can be applied if necessary.

After the metal roof underlayment is installed, the roofing contractors will often install a layer of felt paper, which helps keep leaks from developing in the attic and provides more insulation. Roofing contractors must adhere to the specified weight of felt paper that is required by local building codes, but the average weight that is most often installed is 30 pound paper.

One of the most unique installation requirements of metal roofing underlayment is that it requires an extra layer of slip sheet, which helps prevent the metal from sticking to the felt paper upon installation. However, there is an alternative that can allow contractors to avoid installing the felt paper and slip sheet layers. Contractors can install a polymer underlayment sheet, which is much thinner and easier to work with than the other materials. Polymer underlayment is durable and waterproof, and it is only necessary to install a single layer of it.
