7 Things That Can Damage Your Roof Underlayment


Reading Time: 3 minutes

Roof underlayment is an integral part of your roof’s structure. It serves as an extra layer of protection in the event that something happens to your roof. However, underlayment is not indestructible and there are some things that can cause damage to it. Making sure that it’s protected means an extended life for your roof and keeping your house safe.

When it comes to your roof underlayment, choosing the right material is key. Avoiding damage after that should be your next priority. To help keep your roof safe, here are 7 things to look out for that can damage your roof underlayment.

1. Poor Installation

When a roofing contractor installs the underlayment, it’s important that extra care is taken to make sure it’s in great condition. It’s important to make sure there are no tears, or other damage.  As part of the installation, it is also crucial that manufacturer-approved fasteners are used. This will ensure that the underlayment performs as it should and doesn’t void the warranty. Poor installation can lead to damage so it’s important to hire the right roofing contractors for the job.

2. Degradation of Volatile Organic Compounds

Asphalt underlayment contains volatile organic compounds. This material is initially used to increase the strength.  But these VOCs tend to degrade overtime, and even more so in hot weather. When this happens, the underlayment loses a lot of its strength and becomes more moisture absorbent. This causes it to be less durable and increases the risk of failure.

3. Bad Quality Materials

When an underlayment material is poor quality, it’s more likely to degrade quickly and fail. It’s considered poor quality when it’s made of low-end asphalt felt. Some roofing contractors choose to use this material because it’s cheaper but ends up costing you more to replace. This can also cause roof damage as water ends up seeping through.

4. UV Radiation Exposure

Different types of underlayment have different resistance levels when it comes to UV exposure. For example, asphalt felt is easily damaged by UV exposure and causes it to quickly deteriorate. The best product to use for UV exposure is Tag & Stick which can give up to 180 days of UV exposure. So, for homes in South Florida, this would be the best product to use.

5. Roaming Animals

One of the things that many contractors fail to consider, is the impact of wild animals on your roof underlayment. For example, raccoons and squirrels will try to get into your home through the roof. An important tip to consider is to ensure your tall trees are trimmed regularly so that they can’t use them to climb onto your roof. It’s also important to get

regular roof maintenance so that roofing professionals can check if your roof has been compromised by these animals.

6. Moisture Exposure

Over exposure to moisture is often a cause of underlayment damage. Tag & Stick is designed to provide an excellent seal on the roof deck to limit moisture exposure.

7. Extreme Temperatures

Extreme temperatures can also cause damage to your roofs underlayment as the material will expand and contract, causing it to break. Tag & Stick performs best in extreme heat as it is designed to be temperature resistant and is less likely to break compared to traditional felt or other materials.
