Your roof safeguards your house from many natural incidents. A basic thing which everyone knows, but the things that are unknown to most of us are the components that go in to the entire roofing system. Perhaps you have never heard of roof covering underlayment. It is vital for your roof’s everyday safety.

Many people are interested only in noticeable elements of the structure and never bother about how it is made of. The old saying “out of sight, out of mind” holds true and roofing is not exception for that. As far as roofing is concerned most homeowners think that replacing the roof is the solution; they are often more worried about great looks than the role it plays which is not noticed.


What is the Roof Underlayment?

In simple terms, rooftop underlayment is a layer of material that is situated between roof structure and its last coverings, such as shingles, shakes, or porcelain tiles. While good shingling and flashing installation is very essential, getting a top quality, appropriate roof underlayment to go with it can make all the difference. This safeguards roof beams from water damages, therefore decreasing the chance of leakage and rot because of dampness.


When the roofing develops the drip or the lose shingle, underlayment will not stop water from reaching the decks and framing. Yet, professional roofing contractors use it and numerous area development code needs it. When using tar or felt residue papers according to the design, installing it does make sense.


There are 3 primary kinds of roofing underlayments:


Asphalt-saturated felts

The most commonly used underlayment.  It can be made with a substrate that is organic or fiberglass. It is water resistant, however, not waterproof.


Non-bitumen underlayment (synthetic)

This is called as “synthetic or artificial underlayment” which can be made from multiple sources of materials. They are lightweight but are high in strength. They have a high resistance to UV damage and considered good moisture barriers. It does need to be installed correctly by a professional who understands that it cannot be installed like asphalt felt.


Rubber asphalt underlayment

The weather surface may have a polymer film that is bonded to it that helps resist moisture. It also helps to be skid-proof and weather resistant. It is a good option for metal roofing as it is designed to withstand high temperatures.


Why roofing underlayment is required?


  • It is the moisture buffer.
  • Roofing underlayment offers your roof an extra safety that shingles cannot give.
  • Your shingles are the first line of protection. Shingles reflect the sun-rays, endure wind, and block precipitation.


But shingles overlap and are not sealed at all edges. They can easily get lifted by the strong wind and makes shingles susceptible to wind-powered rain. Shingles could turn out to be fragile and the temperature of an non-ventilated attic will damage your shingles, as well. So be sure that you have underlayment and check it when you are doing your roof’s winter maintenance.


Why the warranty is important

Check your roof’s guarantee – it will determine how and where the underlayment needs to be installed.

Having a high quality, properly set up rooftop underlayment, guards you against multiple roofing issues, which means the property owner will be spending less for upkeep and fixes in the long run. Be sure to talk to your roofing professional to help you decide which type of underlayment your need for your property.
