Why the Roof Underlayment Is Important

Your roof is an essential component of your home’s exterior. It protects your house from all kinds of weather, and it can successfully perform this role due to its various parts and layers, including the underlayment.

Roof Underlayment

The underlayment is found beneath the roofing shingles and provides an additional layer of protection against water.

Benefits of Roof Underlayment

Underlayment adds another layer of protection against water infiltration. It prevents leaks during heavy rain and excess snow. In case your shingles are damaged or blown off by a strong wind, the underlayment can act as a barrier shielding your interior from the elements. Poor underlayment can lead to significant water damage, so make sure to call a professional right away if your shingles have been compromised.

Types of Roof Underlayment

  • Asphalt-saturated felt was the standard underlayment until about 15 years ago, when synthetic materials became more common. Nevertheless, it is still a dependable underlayment material due to its flexibility and water resistance. It is also widely available, and it is the least expensive.

  • Non-bitumen synthetic underlayment is the most common type of underlayment nowadays. Your roofing company will likely recommend it because it has better water resistance than asphalt-saturated felt. It’s also intended for full coverage of the entire roof, making it a cost-effective option for homeowners.

  • Rubberized asphalt is a premium underlayment that offers all the benefits of asphalt-saturated felt and non-bitumen synthetic. It is completely waterproof due to a higher content of asphalt and rubber polymer. The only disadvantage of this underlayment is its higher cost.
