Schenectady Roofing: Article About Underlayment
With so many other choices to make when installing a new roof, choosing a suitable material for the underlayment may fall by the wayside. Some professionals may not even discuss this part of the roofing process, but it benefits property owners to be informed about the material that will lie on top of the decking. This material is designed to protect the decking as well as the actual roofing product. Talking with an experienced Schenectady roofing professional can help property owners decide on the best product for their home. Here is some basic information to assist with the decision-making process.
Underlayment comes in two basic types: felt or fiberglass paper that is coated with a petroleum product and synthetic polymer underlayment. The felt or fiberglass paper, also called tar paper, has been used effectively for many decades. Tar paper is durable and is leak resistant. It is available in both 15 and 30 pound weights, with the greater weight providing more water resistance. Additionally, tar paper is quite economical as well.
There are some draw backs to felt materials, however. It is heavy and can be difficult to install. The petroleum products that it is infused with make it slippery, so it requires care during installation to keep the roofers safe. It can be damaged by workers walking on it, and, if exposed to sunlight, it will break down quickly.

Synthetic underlayments are more costly than tar paper, but they have some benefits that tar paper does not. Synthetics are much lighter in weight and thus easier to install. They are not slippery like tar paper, so they are safer to install as well. Synthetic products provide better moisture protection than felt or fiberglass, and they often provide a radiant barrier. One of the most attractive features, however, is their longevity. Synthetics can last significantly longer than tar paper products.
In past years, and often still today, the most common roofing material was the asphalt shingle, which has a lifespan of about 20 years. However, many property owners are opting for metal or other more longer-lasting materials. Most of these newer products are warrantied for up to 50 years, so it is important to use an underlayment option that will last as long as the roof will. Synthetics will hold up for these extended periods and perform well throughout that time.
For some property owners, cost will be the major deciding factor, so it is important to keep in mind that both products do work well. An experienced roofer will provide the best guidance on an underlayment based on the type of roofing product used.
