Understanding Roof Underlayment for Asphalt Shingles
Roof underlayment is a crucial component in the installation of asphalt shingles, providing an additional layer of protection between the shingles and the roof deck. Typically made from either felt or synthetic materials, the underlayment acts as a barrier against water infiltration, ice dams, and other potential sources of damage. It serves as a secondary waterproofing layer, ensuring the longevity and durability of the roof system.
One of the key functions of roof underlayment is to prevent water from seeping through the shingles and into the underlying structure of the roof. This helps to safeguard the roof deck against moisture-related issues such as rot, mold, and mildew. In regions prone to heavy rainfall or snowfall, a high-quality underlayment is essential for protecting the integrity of the roof and preventing costly repairs down the line.
