What Lies Beneath: The Essential Layer of Roof Underlayment

roof underlaymentEvery homeowner wants to make sure that their roof functions well and provides the utmost in protection. And this is the time of year when issues around leaking and water damage can begin to arise.

Most people tend to focus only on the visible aspects of a structure, not really thinking about what goes on beneath. True to the old “out of sight, out of mind” adage, it’s no different when it comes to roofing. What most homeowners tend to think about when discussing roof replacement of any kind is the uppermost, evident layer; they are often more concerned more with good looks than the role of what can’t be seen.

Right below the surface, however, sits one of the most important components of any roof system.

What is Roof Underlayment?

In the most basic sense, roof underlayment is the layer of material that sits between the roof structure and its final covering, such as shakes, shingles or tile. While good shingling and flashing installation is extremely important, also having a high quality, appropriate roof underlayment to go with it can make all the difference. This protects roof beams from water damage, thereby reducing the chance of leaks and rot due to moisture infiltration.

Traditionally, an asphalt-saturated building paper functioned as the primary weather barrier between roofing materials and the roof structure itself. These days, there are a number of other options for roof underlayment material, from rubberized asphalt to fibreglass. The best underlayment will prevent moisture and both hot and cold uncomfortable temperature extremes from entering your home, as well as give your roof a longer life.

The right kind of roof underlayment material for the job is specifically selected by roofing company experts and might be made of:

  • Rubber-based asphalt
  • Plastic polymers
  • Fibreglass
  • Synthetic materials
