Roofing Underlayment: Everything You Need to Know

The underlayment is a water resistant barrier that protects the roofing system from leaks and water damage. Read on as we discuss the importance of this critical roofing component as well as the three types of underlayment products to choose from.

Asphalt Saturated

This was the most common underlayment material installed in roofs until synthetic materials became more commonplace around 15 years ago. While its popularity has waned, it’s still a reliable underlayment because it’s flexible, water resistant, widely available and affordable.

Non-Bitumen Synthetic

Alternatively, you can also have your roof repair expert install non-bitumen synthetic as your roof’s underlayment. Currently, this is the most common kind of underlayment as it provides better water-resistance than asphalt saturated underlayment and is also designed for full application on your roof. This makes it more cost-effective for homeowners who are working on a budget.

Rubberized Asphalt

If you don’t mind spending a little extra on your roof’s underlayment, you can also consider installing rubberized asphalt. This high-end option boasts the benefits of non-bitumen synthetic and asphalt saturated underlayment. However, unlike these other two, it’s completely waterproof due to its high percentage of asphalt and rubber polymer.
