Synthetic Underlayment

Choosing the right underlayment for your roof is critical in Florida. From blazing hot sun to extreme wind and rain, the underlayment plays an important role in protecting your home. There are many options to choose from. The experts from Triangle Roofing, Inc. can evaluate your needs and recommend the right solution. Each type offers unique benefits for your new roof.

What is Roof Underlayment?

Roof underlayment is a protective layer the roofer installs between your roof's wooden decking and the shingles or metal roofing. It is a huge layer of material that keeps rain and water out of your home. It also is the foundation for your shingles. The two of them together waterproof your roofing.

Keep in mind that there are a few different options for underlayment. Some are heavier and last longer, while others are highly engineered and lighter, but may cost more. The most important thing to keep in mind is ultimate protection. Depending on the roof lines of your home and previous roofing materials, you will have a range of choices and prices. The professionals at Triangle Roofing will know what's best for your home.

If your roof is flat or low-slope, the required roofing materials may be different. This application must be installed by a flat roofing expert and Triangle Roofing, Ormond, is the right choice.

Underlayment Types

In Florida, synthetic or felt underlayment is used for most residential housing. Synthetic underlayment is a great choice because it is stronger than felt. Keep in mind that local building codes may dictate what your roofer can use, as well as how many layers may be needed. Owens Corning, GAF, and CertainTeed are some popular brands we use at Triangle Roofing, Inc., Ormond Beach.

Felt Underlayment

This felt is made from recycled glass, plastic, or fiberglass. These felt sheets are also called asphalt-saturated underlayments. This is one of the oldest types of roof underlayment available. It can be cut and installed easily and is very reliable. When the Triangle Roofing, Inc. team tears off old roofing, we often see this popular choice underneath the old roof. This doesn't mean you have to use felt again, however. You may decide a peel and stick, or nail-down synthetic is better for your home.

Synthetic Underlayment

This underlayment is made from polyethylene or polypropylene. Fairly new to the roofing industry, it offers high durability, and tear resistance capabilities. Like felt, it is also available in multiple thicknesses but is a very lightweight material. Owens Corning Titanium is an example of an excellent choice. This coated woven synthetic roofing underlayment is installed with nails. It is unaffected by water which means no mold and it will not wrinkle.

Peel and Stick

Stick-on underlayment is a newer option that's gaining popularity. It has a peel-off backing and sticks directly to the roof deck. It forms a tight bond with the roof deck, with no seams, reducing the risk of leaks and wind damage. No nails are used so this roofing underlayment is quick to install. It also is very durable and may not need to be replaced as often as felt. But it needs to be installed the right way! Triangle Roofing, Inc. has the roofer experience you need for this type of application.


The cost of materials may affect your final decision. One of the reasons why roofers use felt underlayment is because it’s more affordable. Synthetic underlayment is the more expensive option when compared to felt because of its higher durability and longer lifespan. However, it proves to be cost-effective in the long run. Its durability does not require much maintenance or frequent replacement compared to felt. Again, the local roofing codes and your insurance company will likely influence your decision.

Triangle Roofing, Inc. can help you make the right choice for your budget and project needs. With the right choice and superior installation, you'll have a new roof that keeps your home safe and dry in the ever-changing Florida weather. Got questions? More information is available on our FAQ page.
