At Aspen Contracting, we want our customers to be informed about the materials that go on their roof. Today, we’re going to dive into roofing underlayment and explain its importance in the preservation of your home.


To start, roofing underlayment is a layer of material installed between the roof deck and the roofing material (such as shingles, metal, or tiles) to provide additional protection for the building. It is typically made of synthetic materials, such as rubber or polymer, and is designed to be water-resistant. The purpose of the underlayment is to prevent water from penetrating the roof in case of leaks or other damage to the roofing material, helping to extend the life of the roof and prevent water damage to the interior of the building. In addition to its waterproofing properties, roofing underlayment also serves as an air and vapor barrier, helping to regulate temperature and prevent moisture buildup.


Roofing underlayment is necessary as it provides a secondary line of defense against weather and water damage to a building’s interior. It serves as a barrier between the roof deck and the shingles, protecting the roof structure and the inside of the building from leaks caused by wind-driven rain, ice dams, or other forms of precipitation. The underlayment also provides added insulation, helping to regulate temperature and prevent heat loss. Additionally, it helps extend the lifespan of the roofing system by providing a protective barrier against the elements.


To determine if you already have roofing underlayment, you can do the following:


1. Inspect the attic: If you have access to the attic, look for a layer of material between the roof deck and the shingles. If present, it’s likely that you have an underlayment installed.

2. Check the roof deck: If you can see the roof deck from the ground, look for a layer of material between the deck and the shingles.

3. Look for signs of leaks: If you have had leaks in the past, but your roof is relatively new, it’s possible that the underlayment has failed. Check for signs of water damage or staining on the ceiling or walls.

4. Consult with a professional: If you’re unsure, consider hiring a professional roofer to inspect the roof and determine if an underlayment is present and in good condition.

Keep in mind that not all roofs have underlayment, especially older ones, and it’s always a good idea to have a professional inspection to determine the condition of your roofing system.
