What Is Underlayment?
Roofing underlayment is a protective layer applied directly between the tile and the decking. This layer protects the roof and the inside of the building from extreme weather and moisture. Underlayment roof installation is necessary for many reasons, including:
- It protects your roof from moisture during the roofing process and for a long time after.
- It acts as a barrier between the water and the inside of your home if the roof is somehow damaged.
- It adds a layer of protection from sound and heat.
- It acts as a non-slip walking surface for roof-installers.
- It prevents the leaching of chemicals from your roof shingles onto your roof deck, which keeps the roof stronger for longer.
What You Should Know About Tile Roof Underlayment
While underlayment is always an essential step in roofing, it is especially useful in Phoenix, AZ, as it often climbs above 100 degrees in the summer. To maintain a comfortable temperature in your home, sufficient protection from the heat and sun is necessary. Roofs are constantly exposed to sun radiation, wind, weather, water, and countless other hazards. For a roof to properly protect the home and family inside, it must be sturdy and durable. A big part of the durability of a roof is due to the underlayment material, rather than the shingle material. There are three main categories of roofing underlayment:
- Asphalt-Saturated: Asphalt-saturated underlayment contains a high concentration of asphalt, which is part of the reason why it is so effectively water-resistant. The asphalt-saturated underlayment consists of:
- Natural plant fibers
While this is a good material and can be installed across the entire roofing deck, it’s mostly only water-resistant rather than waterproof. It may work to protect the roof from some weather and water related damage, but a waterproof underlayment option is a great way to go for areas that receive a lot of water. In some cases, asphalt-saturated underlayment may be perfect. For example, if heat is the main thing that you’re looking to protect your home from, this would be a great option.
- Rubberized Asphalt: Rubberized asphalt adds an additional component to the underlayment that further protects the roof from damage. It is made from a high percentage of asphalt content and rubber polymer content, which results in a thick and waterproof option. Because of the waterproof nature of rubberized asphalt and the durability and protection it adds to your home, this is the most expensive option.
We highly recommend rubberized asphalt underlayment for areas that receive extreme weather in both directions. For cold regions, the roof is protected from heavy snowfall and moisture. The underlayment, depending on the ratio of the components, can resist the heat up to 250 degrees without wearing on the adhesives—which is great for hot regions like Arizona.
- Synthetic Roofing Underlayment: Synthetic underlayment is one that is preferred by many roofing professionals. Its base-mat consists of a high asphalt saturation which provides water-resistance while also being incredibly heat-resistant and durable because of the fiberglass addition into the underlayment. It offers many benefits, including:
- The material is lightweight and thinner than other underlayment, which is better for the roof.
- It is less slippery, which reduces the risk of accidents and injuries during repair or installation.
- Scrim reinforcement can be added to increase slip resistance.
- Synthetic roofing underlayment is easy to install.
- The material tolerates high heat very well, which makes it extra popular here in Phoenix.
- It degrades slower and lasts much longer than many materials used for underlayment.

When to Replace Your Tile Roof Underlayment
The most used underlayment—asphalt-saturated felt—usually lasts anywhere from 12 to 20 years before it starts to deteriorate. Sometimes though, roofing underlayment won’t last that long. Factors that can cause early deterioration include:
- Poor installation
- Lack of maintenance
- Low-grade underlayment
- The absence of hip and ridge closer
- Undersized channel metals
