Why Is The Roofing Underlayment Important?

The roof is one of the most noticeable exterior features of any home. Despite this, many people still think that it only consists of what they can easily see: the shingles, gutters and, maybe, the plumbing vents. But in reality, the entire roofing system is a collection of structural components that work together to effectively defend your home from weather conditions and elements.

The roofing underlayment is one those hidden components. Mostly water-resistant, it is the barrier directly underneath the top-most material on the roof. Homeowners don’t realize the importance of this additional layer until it’s time for a roof replacement. But what makes it so important?

  • It is a moisture barrier. There are many reasons why moisture seeps through the roof, including failing to switch on the exhaust fan during showertime and insufficient ventilation in the attic. So, excess moisture builds up in the air and accumulates underneath the roof, comprising structural components that are wood-based. The underlayment prevents moisture-related damage by removing water that results from condensation.
  • It is water-resistant. Underlayments made from asphalt-saturated felt and non-bitumen synthetic material are water-resistant while rubberized asphalt has a sticky back that acts as a waterproof protective membrane between the underlayment and roof deck. Alleys and areas around protrusions need to be protected from water.
  • It is a protection during roof repairs. Another benefit of adding roofing underlayment is having a non-slip walking surface for roofers. Roof repairs here and there are inevitable, especially after extreme rainstorms so it’s incredibly important that roofers have a smooth walking surface to protect them from accidents and further damages.
