One of the most crucial roofing materials is the underlayment. This is a layer of material between the shingles and roof deck, blocking out moisture and strengthening the roof. There are many different options for this material to suit the needs of homeowners. Below are the main types of roofing underlayment available and how they can benefit your home.

A Guide to Roofing Underlayment

1. Asphalt-Saturated Felt

Better known as roofing felt, this material comes from the tar paper that pioneer homes had in the 1800s. This material is fiberglass and asphalt, and while it’s highly water-resistant, it’s not entirely waterproof if saturated fully. Usually available in 15- or 30-pound grades for residences, heavier weights are sturdier and more resistant.

Roofing felt was the most popular underlayment roofing material because the asphalt in it resists wet weather and fire. However, it faces competition from materials that are more effective under ultraviolet (UV) rays and constant heat.

2. Rubberized Asphalt

Rubberized asphalt is a sturdy, rubber-like roofing material that manufacturers make from bitumen, a by-product of petroleum production. This material has several properties that make it popular among homeowners and roofers alike. It needs no nails, adhering directly to the roof deck and creating a complete, watertight seal that provides a perfect base for shingles.

It’s also safer for installation and repairs since the tough, flexible material is non-skid. You can use it on a wide variety of surfaces, including concrete and wood, and it can withstand heavy rain, hail, snow, and UV rays.

3. Non-Bitumen Synthetics

Representing the latest development in underlayment roofing materials, non-bitumen synthetics are lightweight polypropylene or polyethylene sheets. These work especially well due to their water resistance and adaptability. Non-bitumen synthetics resist mold, mildew, algae, and insects, and they perform equally well in defending against sleet, hail, and UV rays.

However, you must be careful during the installation of this underlayment, because improper fitting can cause incomplete seals and allow water inside. This will damage the joints and seams, as well as rot the wood in your attic.
