Why Old Underlayment Has to Be Replaced

Norfolk homes are usually exposed to various weather conditions ranging from the sweltering heat of summer to the chilly winds of winter. The durability of your roof doesn’t just depend on the outer layer that everyone sees; the underlayment plays a pivotal role in safeguarding your home from moisture damage. This brings us to the critical reason why old underlayment needs to be replaced—especially during a roof replacement project.

Enhancing Roof Longevity and Performance

The underlayment is a barrier between the roof deck and the shingles that protect the roof from water intrusion. Over time, this protective layer can become compromised due to wear and tear, leading to leaks and water or storm damage. Replacing the old underlayment during a roof replacement ensures your roof has a solid foundation, enhancing its longevity and performance.

Preventing Moisture Damage

In Norfolk, VA, where humidity levels can be quite high, the risk of moisture damage is more pronounced. Old underlayment, which may have lost its integrity, can no longer provide the reliable moisture barrier your home needs. By opting for a tear-off and replacing the underlayment, you mitigate the risk of mold, rot, and structural damage that moisture can cause, securing your home’s interior from potential hazards.

Complying With Building Codes

It’s also worth noting that building codes and manufacturer’s warranties may require the replacement of underlayment during a roof replacement. These requirements ensure that roofs can adequately protect homes against local weather conditions. Ignoring these rules can lead to non-compliance issues, potentially affecting the validity of your roof’s warranty and your home’s insurance coverage.

Cost-Effectiveness of a Tear-Off 

Opting for a complete tear-off, including the removal of old underlayment, might seem like a costly investment initially. However, it is more cost-effective in the long run. This allows for the inspection and repair of any hidden damage on the roof deck, ensuring that the new roofing system is installed on a sound structure. Additionally, with the technological advancements in underlayment materials, replacing the old material can significantly increase durability and lessen the chances of needing roof repair.

Energy Efficiency and Your Home’s Comfort

Lastly, a new underlayment can contribute to better energy efficiency in your home. Advanced underlayment materials provide an additional layer of insulation, keeping your home warmer in the winter and cooler in the summer. For residents, this means not just a comfortable living environment but also potential savings on energy bills.

While the outer materials of your roof are what you see, the underlayment beneath serves as the unsung hero, working tirelessly to protect your home from the elements. Roofing services provider M&A Exterior Home Improvement strongly advises Norfolk homeowners to consider the many benefits of replacing old underlayments during a roof replacement.
