Purpose 

According to roofing companies in Overland Park, the roofing underlayment plays a significant role in protecting a roof from being exposed to weather such as hail, rain, and wind. It is water-resistant and is installed on the roof deck under all of shingles, membrane, and other materials. 

 

Types of Underlayment 

 

Asphalt-Saturated Felt 

One of the most common underlayment material used among roofing contractors in Overland Park is black, asphalt-saturated felt. The felt is made of a variety of natural fibers, polyester, and asphalt. It is then saturated in asphalt, making it water-resistant. The felt paper typically weighs in different categories such as 15 lb. and 30 lb. 

Synthetic  

Synthetic underlayment is another prevalent material that the best roofing companies in KC use. Synthetic underlayment is also saturated in asphalt and includes fiberglass, making it resistant to tear. This material is immune to fungal growth, resistant to UV rays, and doesn’t absorb moisture.  

Rubber 

Rubberized asphalt contains asphalt and rubber polymers and is the more expensive type of roofing underlayment. Rubberized asphalt has a unique, sticky backing that gives it a waterproof sealing to protect the roofs deck edge from water. Roofers in Overland Park typically install this underlayment around protrusions and valleys of a roof. 

As you can see, the underlayment is crucial in acting as a moisture barrier and protects the roof from extreme weather and damage.
