How to Know If Your Roofing Underlayment is Damaged and What to Do About It

One of the most important parts of a roofing system isn't seen. The underlayment is a waterproof material that is laid on top of the roof deck to protect it and everything underneath. It provides an additional layer of protection against water damage, storm damage and the tar paper of asphalt shingles. It's absolutely essential that the underlayment be in good condition or the entire roof system could be jeopardized.

When we explain this to clients, many of them have the same question. If the underlayment is installed underneath the top layer of roofing material, shouldn't it be protected? In theory yes, but there are a number of things that can damage the surface of roofs and the underlayment below.

Common Reasons Roof Underlayment Material Gets Damage

It doesn't matter if you have felt underlayment or synthetic underlayment. Damage can occur to both types of underlayment material if things aren't installed correctly and properly maintained. Below are some of the most common issues that can damage or compromise the roofing underlayment no matter what type of roof you have.

  • Issues When the Roofer is Installing Underlayment Material

    A roofer must install underlayment properly or there could be major problems even if the surface materials are in perfect condition. It's crucial that the roofers roll out the underlayment smooth so that it lies perfectly flat when it's installed. The underlayment also needs to be snug but not too tight in order to function properly.

    The underlayment might not be properly sealed during the installation, which leads to other problems. Without good sealing, the underlayment won't be a waterproof layer. However, there still needs to be adequate ventilation with synthetic underlayment or moisture can get trapped underneath.

    One other issue to watch out for with roofing underlayment installation is how the material is stored and handled. If the underlayment is exposed to the heat prior to installation it can degrade the material and increase the risk of cracking and blistering after it's installed.


  • Not Using the Correct Type of Roof Underlayment

    When a roofer doesn't follow local building codes there's a good chance the wrong underlayment material will be used that isn't adequate for the region. There are also local codes for the number of layers that should be installed and the overlap based on the roof pitch and the environment. For example, in Texas a steep roof with a slope that's greater than 33% only needs to have one layer of underlayment. There are also city roofing codes that may be more restrictive than the state building codes.


  • Roofing Nails That Puncture the Underlayment

    Installing fasteners that are too long is a big problem. If roofing nails and fasteners that are used to secure the top layer of the roof are too long they will often puncture the underlayment below. When that happens the roof underlayment no longer provides a water-tight seal and moisture can seep down to the roof deck.

    In addition to using the correct size, fasteners also need to be corrosion-resistant and spaced appropriately to keep the roof underlayment in place.


  • Surface Roof Leaks That Aren't Fixed

    The underlayment is a second layer of protection in case the surface of a roof is damaged and water leaks through. But that doesn't mean the underlayment is indestructible or that surface roof leaks don't need to be fixed. It's actually quite the opposite. If the top layer of a shingle roof or metal roofing is damaged and allows water to seep through, eventually the underlayment will be damaged too. It's one more reason why regular roof maintenance is so important.


  • Damaged Seals

    If you have metal roofing or a flat roof system, it may not be the roofing material itself that gets damaged and allows water to penetrate through to the underlayment. The seams where metal panels and roofing material meets can become damaged and allow water to leak through. It's often the result of the seal over the seam weakening, fasteners failing or extreme temperatures causing the roof material to contract and expand, causing the seams to widen.


  • Storm Damage

    Hail and high winds can do a lot of damage to roofs, even below the surface. If the top layer suffers storm damage or is torn off, the underlayment is exposed and can be damaged as well.


  • Improper Install of Drip Edge Flashing

    There are a number of ways the drip edge flashing can be installed improperly and cause problems with the underlayment. For starters, if the drip edge flashing is installed directly over the underlayment it can trap water that causes the material to rot and allows water to leak through. It's best practice to install the drip edge first then the underlayment to avoid this issue.

    Another drip edge installation problem is not installing it far enough past the fascia. The drip edge needs to extend well past the fascia so that water flows away from the house instead of wicking back up.


  • Extreme Heat and Cold

    Like other parts of the roofing system, the underlayment is susceptible to extreme heat and cold. The heat can break down the underlayment material, particularly if it's a synthetic underlayment. In cold regions the places on the roof where ice dams form, like in the eaves, need to have an ice barrier rather than standard underlayment. The ice barrier can be two layers of underlayment that are fused together.

    Swings in the temperature from hot to cold or cold to hot are also problematic for the roof underlayment. It can cause the underlayment to expand and contract, which can cause the material to break.

How to Prevent and Correct Roof Underlayment Problems

You can't avoid all roofing issues, but keeping the underlayment in good condition is possible if you follow the advice below.

  • Get a Roof Inspection to Assess the Condition

    If you think your underlayment may be damaged the first thing you'll want to do is get a thorough roof inspection. A professional roofer can examine the condition of the roofing system and even detect if the materials were installed incorrectly. From there you'll know how to correct any existing issues to prevent further damage.


  • Use a Reputable Roofer That Follows Local Building Codes

    Whether you're installing a roof or correcting damage that's already impacting the underlayment, it's extremely important to use a reputable roofer that will follow local codes and the manufacturer's recommendations. This will ensure that the correct materials are used and that they are installed properly.


  • Practice Proper Roof Maintenance

    A lot of times damage to the underlayment can be avoided with regular roof maintenance. When the roof is properly maintained you can catch and correct minor problems before they get so big they affect the underlayment.

"I got three inspections and decided to use LOA Construction for a new roof. LOA’s Dan Harvey worked with my insurance inspector to make sure all the hail/wind damage was accounted for, gave us a good choice of shingle colors, and was great at communicating. The workers did quality work, found and repaired rotted wood and cleaned up. Highly recommend!"

"Brandon at LOA construction made replacement of our roof very easy. He was the only roofing contractor that I could find that would work directly with our insurance company. They showed up on time and made the whole process very easy. And we have a great looking high quality roof! I Would definitely recommend them to anyone looking for a new roof. Give them a call if you need a roof or think you might have wind or hail damage. I had several other bids that were higher cost and didn't think our insurance would cover it. Our insurance did cover it, I think they were just unwilling to work with the insurance company. Not Brandon, not only was he will to work with our insurance he met with the adjuster and made the whole thing a breeze. Thanks again LOA and Brandon!!!!"

LOA Construction has exceeded my expectations again. This is the second roof installation with them and I couldn't be happier. Specifically, Tyler Griffiths is professional, attentive, and made the entire process of working with my insurance company effortless. My tenant sent a glowing account of their experience as well. Knowing it was a rental, they still diligently protected all property and plants. They were on time every time and went out of their way to not inconvenience the residents. LOA Construction has integrity and takes pride in their work. I couldn't recommend them more.

Can't thank you enough Andrew and LOA Construction.

As a first time home owner with no experience in how to make claims and start the process of getting a new roof I was scared to the point of avoiding what needed to get done after the bad hail storm. August Walker did an amazing job walking me through each step along the way. He answered all my questions and calmed my concerns. They inspected my roof and drove from Austin to Belton just to be there with the ins inspector, and followed up with me in person after the roof was installed. He also made a special trip back to drop off samples! I’m grateful to August and LOA construction for being highly professional and friendly!
