Roofing systems are more complicated than you might expect. They are made of different layers and features with specific functions. One of them is called ‘underlayment.’ 

Some may suggest that an underlayment isn’t always necessary but experts say it should be applied to low-sloped roofs and specific high-water risk locations of your home. In this post, we will share reasons why you should consider having one for your roof maintenance.

  1. An underlayment is designed to be installed under all your roofing materials as an extra sheet of water penetration protection from weather damage and possibly other elements. Hence, it adds another water-resistant layer to the top of your home. And with it, the prevention of leaks following storms or heavy rain and high snow accumulation.

  2. An underlayment also provides an extra cover shielding your roof if shingles get blown off by high winds or heavy storms. The roofing underlayment will serve as a defense while repairs are ongoing.

Types of Roof Underlayment:

  • Asphalt-Saturated Felt: This is once the most popular and oldest kind of underlayment option. Its material adds stiffness to the roof deck, which improves its durability against impact from hailstones, airborne debris, and large tree branches.

  • Rubberized Asphalt: This flexible material is sheets of rubber with little to no asphalt content. It is ideal for both hot and cold climates.

  • Non-Bitumen Synthetics: These are made of hard-wearing plastics such as polyethylene or polypropylene and have seen use from food-grade containers to plastic models. Nowadays, roofers prefer this material because of its exceptional strength and durability in waterproofing.
