What is roof underlayment? 


In simple words roof underlayment is the protective barrier installed between the framing materials and the top layer of shingles, it acts as a waterproofing barrier, blocking any moisture from creeping into the under-layers of your roof and creating damage. Not only that, but it also adds a layer of protection to your roof against weather conditions such as: wind, rain & snow.


Types of underlayment 


  • Synthetic Underlayment

Synthetic underlayment is a roofing accessory created by weaving/spinning together polypropylene or polyethylene and a polymer to form an all-over protective barrier to put between the roofing material and the roof deck.

This roofing material is the latest innovation that is taking over the roofing industry as a better, more advanced replacement for felt underlayment. Most synthetic underlayments are mechanically attached with roofing caps and staples, while others have a glue backing.

  • Rubberized Asphalt

Rubberized Asphalt is a noise reducing pavement material that consists of regular asphalt concrete mixed with crumb rubber made from recycled tires.

Asphalt rubber is the largest single market for ground rubber in the United States, consuming an estimated 12 million tires annually.

  • Asphalt-saturated Felt

Asphalt-saturated Felt it’s made of a base, made from natural materials or synthetic ones such as fiberglass, and then coated or saturated with a protective coating such as bitumen (asphalt), which repels water but still allows the product to breathe.
