The following are the benefits of roof underlay:

  • Improved safety

Roofing underlayment in commercial roofing projects can help create a safer roof for your workers and tenants. This reduces the risk of injury to personnel and reduces the liability risk to your company.

  • Better weather protection

A key benefit of using roofing underlayment is that it protects against inclement weather, including wind, rain, sleet, and snow. The layer helps provide extra protection against damage that may occur during storms, protecting the integrity of your roof and keeping water out of your building.

  • Energy efficiency

Another key benefit of using underlayment is that it helps improve energy efficiency in your building. This is because it keeps air from getting in and out through any cracks or gaps in your roof’s surface area, which can help prevent drafts and leaks while improving energy efficiency overall.

  • Improved insulation properties

With proper insulation on your roof, you can keep your building warmer during the winter months and more relaxed during the summer months without using as much energy for heating or cooling purposes. Roofing underlayment will directly impact the insulation properties of your commercial roof, making it an excellent option for commercial roofs everywhere.
