This kind of underlayment normally is made out of organic felt and then saturated in asphalt. It might contain some fiberglass reinforcement for increasing longevity and strength. Felt that is saturated in asphalt is water-resistant for a while, but it will wear down eventually and become penetrable. When more asphalt is used for saturating the material, that makes the underlayment more durable but also more expensive. When it comes to the roofing process, asphalt is the component that is the most expensive. Lower priced underlayment will be of lesser quality and contain less asphalt potentially.

Choosing A Roof Underlayment

Even after learning more about the three main types of roof underlayment, you may be unsure about which type is the right option for your home. In order to determine the best roof underlayment, it’s necessary to consider a few important factors, including the climate, top roof layer material, durability, water-resistance, and cost.

The climate impacts any materials that are installed outdoors because they are exposed to the seasonal temperature changes. For homes located in areas with relatively constant temperatures, asphalt-saturated roof underlayment is a good option, but if you live in an area that experiences extreme temperature changes throughout the year, then rubberized asphalt is the best choice. Synthetics are also a suitable option for areas with broad temperature changes.

Roofs built with traditional asphalt shingles tend to pair well with rubberized asphalt and asphalt-saturated roof underlayment. Similarly, rubberized asphalt and asphalt-saturated underlayment is also suitable for slate shingles. However, if you have a metal roof, then it’s recommended to invest in synthetic roof underlayment because this material is more heat-resistant than either rubberized asphalt or asphalt-saturated underlayment.

However, before installing any roofing materials, make sure you have obtained the proper building permit if required in your locale, and refer to the building code in your area to ensure you’re using acceptable material.
