Best Synthetic Underlayment For Roofing In 2024

The underlayment of your roof is the first layer of protection, and it is very important to make the right choice while choosing the type of material. While going through options for roof underlayment, you might have come across synthetic underlayment.

Synthetic underlayment is one of the popular underlayment choices for both pitched and flat roofs. In this blog post, we will share the 10 top synthetic underlayment options that are worth considering for your roof to help you make a choice that benefits you for years to come.

What Is Synthetic Underlayment Made Of? 

Synthetic underlayment is made from special plastics like polyethylene or polypropylene. It’s designed to keep water, wind, and other nasty weather away from the important parts of your roof. Unlike old-fashioned felt paper (also called asphalt felt), synthetic underlayment is tougher, lighter, and lasts longer.

There are a few different types of synthetic underlayment:

1. Non-woven: This type looks a bit like fabric and is very strong
2. Woven: This kind has a crisscross pattern that makes it extra durable
