👉🏼 What Is A Metal Roof Underlayment? Why Is it Necessary For Your Roof? 

A metal roof underlayment is a layer of material that is installed directly onto the roof deck before the metal roofing panels are applied. It serves as an additional protective barrier between the roof deck and the metal panels.

Metal roofs are one of the most robust roofing materials. This is because the panels made from metal are very sturdy and can withstand harsh weather conditions easily. Many homeowners, therefore, wonder if an underlayment is actually necessary or not. 

In our opinion, regardless of the roofing material you install, an underlayment is a must. Here are a few reasons why: 

  • They prevent water from penetrating the roof deck and leaking into the structure below. 
  • Underlayments enhance the wind resistance of a metal roof system. 
  • Underlayments provide sound-dampening properties that help reduce the noise transmitted into a building.
