Your roofing system is comprised of various layers that help protect your home. One of these is the underlayment, which is critical to your roof’s longevity.
Read on to know more about the role of underlayment.
What Is Underlayment?
The waterproof or water-resistant material installed beneath your exterior roofing components is called the underlayment. It provides an additional layer of protection against outdoor elements and prevents water damage. It is the final barrier that keeps your home’s interior safe from water infiltration. Although some people argue that underlayment isn’t always necessary, experts say it should be used, especially on low-sloped roofs.
Why Is It Necessary?
Aside from improving your roof’s protection against leaks and water damage, underlayment can also help increase your home’s curb appeal. It can flatten the surface where your shingles will be installed, giving your roof a cleaner, more even appearance.
Your roof underlayment can also add a layer of insulation to your home, increasing overall energy efficiency. It can keep conditioned air from escaping, so your HVAC system won’t have to work as hard to keep you comfortable. As a result, you’ll save money on your utility bills.
Types of Roof Underlayment
Asphalt-saturated felt. Before the introduction of synthetic products, most roofers relied on asphalt-saturated felt as the primary roofing material. It’s still a reliable underlayment material due to its flexibility and water resistance. It is also the most affordable type of underlayment.
Non-bitumen synthetic. It’s the most common type of underlayment used today. It offers better water resistance than asphalt-saturated felt and is designed for full application on the entire roof.
Rubberized asphalt. It’s the most expensive underlayment material because it contains higher percentages of asphalt and rubber polymers. Rubberized asphalt is completely waterproof.
