Roof Underlayment

Roof underlayment is a crucial first step in any roofing system, installed beneath shingles, plywood, or OSB to create a water-resistant barrier. Acting as a secondary line of defense, the underlayment roofing paper protects against moisture, ice, and wind-driven rain, helping to prevent leaks and extend the life of your roof. Available in multiple types such as felt, synthetic, and rubberized materials, each underlayment for roofing offers unique advantages in durability, flexibility, and energy performance. Whether you're tackling a steep-slope installation or need added resistance in high-moisture zones, our roofing underlayment options are tailored to meet your specific needs. Designed for performance and long-term protection, roofing underlayment is a smart investment for a secure and weatherproof roofing system.
