What roofing underlayment is and what it does

Roofing underlayment is a material that is installed between the roof deck and the shingles. Its purpose is to help protect the roof deck from water damage in case the shingles are damaged and to provide an extra layer of protection against wind-driven rain and snow. 

Many homeowners are not aware of roofing underlayment and its importance, but any concerned homeowner should be sure to ask about it when having a new roof installed. Quality underlayment can help extend the life of your roof and protect your home from costly water damage. 

When shopping for a new rooftop, be sure to ask your contractor about the quality of the underlayment they will be using. Quality underlayment can mean the difference between a long-lasting roof and one that needs to be replaced prematurely.

The different types of roofing underlayment available

Most homeowners know that the roof is one of the most important parts of the house. It protects against the elements and ensures that your house is warm in winter and cool in summer.

But what many people don’t realize is that the roofing underlayment is just as necessary as the shingles themselves. Underlayment is a water-resistant barrier between the roof deck and the shingles. 

There are different types of underlayment available, each with its own advantages: 

Material #1 — Polypropylene

Polypropylene underlayment is lightweight and easy to install, making it a popular choice for do-it-yourselfers. However, it is not as durable as other types of underlayment and may need to be replaced more frequently. 

Material #2 — Felt paper

Felt paper underlayment is made from asphalt-saturated organic materials, such as paper or fiberglass. It is more rigid and more durable than polypropylene, but it is also heavier and more challenging to work with. 

Material #3 — Synthetic alternatives

Synthetic underlayment is made from man-made materials, such as polyester or fiberglass. It is lightweight and easy to install.
