What Roofing Underlayment Should I Use?

When it comes to putting up a new roof, you may be wondering what roofing underlayment to use. It is important to choose a quality product, but there are some things to keep in mind before you choose one over the other. For example, if you’re planning to use asphalt shingles, you should look for synthetic underlayment. While synthetic underlayments are slightly more expensive than felt paper, they are generally the best option, and they’re also a great choice for smaller projects.

When you’re choosing your roofing underlayment, it’s important to choose the right material for your specific roof type. A synthetic underlayment, for example, will last longer, and it will seal around fasteners and nails. It also has the same ripcord technology as the previous product. A typical roll will cover about 1000 square feet, and it is about 28 pounds. If you’re going with a traditional asphalt shingle roof, you’ll want to go with a felt underlayment, which will allow for the most flexibility.

Another option is the use of asphalt-saturated felt. Despite its low cost, it provides good seepage barriers. However, if you live in a cold climate, it may not be the best option for you. The price of asphalt-saturated felt is also a drawback, and it’s recommended to use a synthetic underlayment when it’s possible. You can install this type of underlayment with common tools.

If you have no experience in roofing, this type of underlayment is a good choice. It’s much cheaper than other materials and provides good seepage barrier. Unlike felt, however, asphalt-saturated felt is heavy and can be difficult to handle in harsh climates. As with other roofing underlayments, it should be applied in conjunction with a felt underlayment. If you’re not sure what kind of underlayment to use, you can try synthetic underlayment.

Among the different types of roofing underlayment, felt has long been used in residential applications. It is made up of a fiberglass mesh material that is impregnated with asphalt. While felt is relatively water resistant, it is not completely waterproof. It can only withstand short-term exposure to weather. Fortunately, asphalt felt comes in two different thicknesses. The thinnest type is 15lb. The thicker, 30lb. type is thicker but more durable and more flexible.

Underlayment is an important part of the roof. A good product will protect it from the elements and ensure that it won’t be damaged by weather. While it may be expensive, it can be used as a back-up plan if necessary. If you’re in a hurry to have your roof installed, synthetic underlayment is a good option. This type of underlayment can be left out longer without damaging the roof.
