Every homeowner wants to protect their home, along with the belongings and people inside, as well as they can. Whether your roof needs replacing or you’re building a new home, choosing the proper roof underlayment is crucial for ensuring your home stays safe and dry.

The term ‘underlayment’ can be confusing if you’re not a professional roofer. Many people don’t know much about their roofing system, and underlayment is not necessarily part of what they do know. When you work with Silver Creek Roofing, we can take the mystery of underlayment out of the equation and help you determine what kind will match your home’s needs the best.

What is Roof Underlayment, and Why Do I Need It?

Roof underlayment is a barrier made of water-resistant materials that provides an extra layer of waterproofing and weather protection to your roofing system. It is just one necessary part of your roof system to provide maximum protection to your home.

Not only does it help increase the safety of your home, but it is also a building code qualification all over the country. A high-quality, professional roofer will always use underlayment to ensure the roofing system is as strong as possible.

What Different Types of Roof Underlayment Exists?

Just like there are several types of roofing for your home, there are also several different types of roof underlayment, each with its pros and cons. Depending on your roofing needs, you may find these benefits or drawbacks aren’t as important, but getting familiar with them is a good idea if you are working on a roofing project.

Asphalt-Saturated Felt

A common type of underlayment—asphalt-saturated felt—is the type with the most extended history of protecting roofs. It is available as either 15-pound or 30-pound options, and it is water-resistant but not waterproof.

The 30-pound felt is thicker and the more widely used of the two. It is affordable and fits most budgets, but it is not UV resistant and breaks easily, which can cause issues during installation. It also breaks down more quickly than other underlayments, especially in warm climates.

Rubberized Asphalt

As the name suggests, rubberized asphalt looks and performs much like rubber. Because many of the rubberized asphalt underlayment options are peel and stick, they are convenient and work well to self-seal around staples, nails, or other imperfections. This type of underlayment is highly effective at protecting against water and snow damage and is more heat-resistant than different types.

Rubberized asphalt is also commonly used and highly effective for areas that receive a lot of snowfall or precipitation. The most common concern with this underlayment is that it can be costly, so it isn’t as affordable as the commonly used asphalt-saturated felt.

Non-Bitumen Synthetic

Of all the types of underlayment, this type is the newest, and it’s been gaining popularity recently. Synthetic underlayment is much lighter than the other two types discussed above and is much more tear-resistant. With this underlayment, you can expect better performance versus the first two types in areas with high winds.

Synthetics have water resistance, and many come with the self-adhesive ability that you will find is typical with rubberized asphalt. To be eligible for roofing warranties, some companies will require that you have a synthetic roof underlayment because they are part of a more effective roofing system than felt is. The main drawback with this type is cost as well.

What’s the Best Roof Underlayment for My Home?

As previously discussed, each roof underlayment comes with pros and cons, but the type you use for your home will depend on several factors. Your roofing materials are the first defense your home has against the elements, but the underlayment needs to be a solid backup support system if your roof is compromised.

Consider the climate of your area and what material you are using for the top layer of your roof. Compatibility between those materials is necessary for the roofing system to perform at its peak.

Your roofer may suggest a thin asphalt-saturated felt for steep slope roofing. A home that experiences a lot of rainfall or snow could benefit from a thicker felt’s ice and water shield abilities. Synthetic roof underlayment could work for a home with a lower-sloped roof in an area with lots of wind.

No matter which roofing underlayment you think is suitable for your home, it is best to speak with professional roofing contractors to determine what will perform best for your roofing system.
