Roofing underlayment, often an unsung hero in roofing systems, plays a pivotal role in safeguarding homes from environmental threats. This layer, nestled between the roof’s shingles and its wooden deck, is crucial for maintaining the integrity and longevity of the roof.
The Indispensable Function of Roofing Underlayment
Acting as a protective barrier, roofing underlayment is essential for preventing water infiltration and damage, especially during inclement weather. It’s a key component in preserving the roof’s structure and ensuring the safety and comfort of the home.
Exploring Various Roofing Underlayment Options
Asphalt-Saturated Felt Underlayment
This traditional and economical option, infused with asphalt, is a common choice for many homeowners. Its effectiveness in water resistance varies with the level of asphalt saturation. It’s particularly suited for roofs with a steep slope but may be less effective under continuous sun exposure or when used with high-end roofing materials.
