There are a lot of materials that go into place on a new roof, and one of the first materials that goes up on your house is something you will probably never see, the underlayment.
Roofing underlayments are an important part of the whole roof. Their primary job is to serve as an extra layer of protection against rain, snow and wind. Roofing underlayments go on top of the sheathing of the roof, which is the plywood base directly attached to the rafters. In the past, sheathing was put on as temporary protection from the elements until the roof was finished, however, contractors have found that leaving the sheathing on and adding an underlayment on will make the roof more weather resistant. Now, building codes require underlayments that meet standards for fire resistance, punctures and wind resistance.
Contractors will use different types of underlayments for different conditions, but fall into three different categories: felts, synthetics, and self-adhering ice–and–water barriers. The most popular roofing underlayments used are asphalt-saturated felt. This felt paper is rolled out onto the deck of the roof and stapled into place. The newest roofing underlayments are synthetics; these are polymers that are easier to work with and tend to be tear resistant, contractors tend to favor this type of underlayments.
Roofing underlayments are an important part of your new roof and your qualified roofing contractor will be able to help you choose the one that will protect your house the best while at the same time, keeping your budget in mind.
