When replacing your roof, you might wonder whether you should keep your old underlayment or replace it. The truth is, for a variety of reasons, replacing old underlayment is not just recommended; it’s crucial for the integrity of your roofing project. As a leading provider of exterior services, BSR explains why a tear-off is ideal during roof replacement and why retaining an old underlayment is not a wise choice.
Underlayment serves as a critical barrier between your shingles and the roof deck. It’s designed to provide an additional layer of protection against water penetration, which can lead to rot, mold, and structural damage. As such, having a reliable underlayment is essential for keeping your home safe and dry.
Over time, underlayment can deteriorate due to exposure to moisture and the elements. An old underlayment may not provide adequate protection, as it’s likely to have suffered from wear, tear, and possible water damage. This can compromise the roof’s integrity, leading to leaks and costly repairs.
A tear-off, the process of completely removing the old roofing materials down to the deck before installing a new roof, is ideal for several reasons. It allows for a thorough inspection of the roof deck and rafters, revealing any hidden damage or areas in need of roof repair. This process ensures that any underlying issues are addressed before the new roof is installed, providing a solid foundation and extending the lifespan of your new roof.
Using a new underlayment with your new roof ensures all materials are compatible and designed to work together. This not only optimizes the performance of your roofing system but also maximizes its lifespan. Investing in a new underlayment is a small additional cost that contributes significantly to the overall durability and effectiveness of your roof.
Building codes often require a new underlayment when replacing a new roof. These codes are designed to ensure that homes meet current safety and construction standards. By replacing the old underlayment, homeowners can ensure their roof replacement project complies with local regulations, avoiding potential legal issues and penalties.
Manufacturers typically require that a new underlayment be used for the roofing materials’ warranty to be valid. Using old underlayment can void this warranty, leaving homeowners without coverage in case of defects or premature failure of roofing materials. It’s essential to adhere to manufacturer guidelines to ensure that your investment is protected.
