In areas where the weather can range from scorching summers to icy winters, the condition of your roofing system is paramount to the safety and comfort of your home. While it’s tempting to cut corners and overlook replacing old underlayment during a roof replacement, doing so can lead to severe consequences down the line. In this post, we discuss why you shouldn’t postpone updating your old underlayment.
The underlayment of your roof serves as a critical barrier between its shingles and the structural decking. This layer provides an additional line of defense against water infiltration, protecting it from rot, mold, and other moisture-related damage. In a diverse climate where roofs are subjected to intense sunlight, heavy rain, or even snow, the integrity of the underlayment is crucial for preventing leaks and extending the lifespan of your roof.
Over time, the underlayment can deteriorate due to continuous exposure to the elements. Old underlayment may become brittle, tear easily, and lose its waterproofing capabilities. This can allow water to seep through and damage the decking, insulation, and even the interior of your home. Replacing the roof shingles without addressing the old underlayment is akin to placing a band-aid on a deep wound—it may cover the problem temporarily, but the underlying issues remain and can worsen over time.
When it’s time for a roof replacement, the best practice is to completely tear off the existing roofing materials, including the old underlayment. This approach allows roofing professionals to thoroughly inspect the decking for signs of damage or decay, which can then be repaired before installing the new underlayment and shingles. While overlaying a new roof on top of an old one might seem like a cost-effective solution at first, it can lead to increased weight on the roof’s structure and mask underlying issues that could require a roof repair down the line.
Adhering to local building codes and manufacturer’s warranty requirements is critical when replacing a roof. Many roofing manufacturers specify that a complete tear-off and replacement of the underlayment are necessary for the warranty to be valid. By ensuring compliance with these stipulations, you can extend the lifespan of your roof and protect your investment with warranty coverage.
Investing in a complete roof replacement, including tearing off the old underlayment, offers numerous long-term benefits. New underlayment technology offers superior protection against water and UV damage, provides better ventilation, and can significantly improve the energy efficiency of your home. Furthermore, taking this comprehensive approach to roof replacement enhances the overall aesthetic appeal of your home and can increase its market value — a crucial consideration in a competitive housing market.
