Roof underlayment installation is a critical step in ensuring the longevity and durability of a roofing system. Acting as a protective barrier between the roofing material and the structure, underlayment shields against moisture, wind, and weather elements. Proper installation helps prevent leaks, provides additional insulation, and enhances overall roof performance. Whether using felt, synthetic, or rubberized asphalt underlayment, the right installation method ensures that the roof remains secure, energy-efficient, and capable of withstanding harsh environmental conditions for years to come.
