Can Mobile Roof Repair Be Applied Over Existing Roof Materials?

Yes, mobile roof repair can often be applied over existing roof materials, provided the current roof is in a satisfactory condition. This method can be an effective and cost-efficient solution for extending the life of a roof, especially in cases where the existing roof is structurally sound and there are no leaks.

Condition of the Existing Roof

The key to successful mobile roof repair lies in the condition of the existing roof. If your current roof is stable, with no structural damage or leaks, adding an additional layer of roofing material can significantly extend its lifespan. This approach is particularly useful in situations where the roof is old but still in fair condition, and retrofitting it with new materials is a more practical solution than rebuilding from scratch.

Type of Coatings and Their Durability

There are two primary types of coatings that can be used for mobile roof repair: elastomeric coatings and silicone coatings. Each type has its own characteristics and lifespan.

Elastomeric Coatings

Elastomeric coatings are designed to provide a temporary repair or waterproofing solution that lasts for a few years. They are relatively inexpensive and work well for quick fixes, especially in emergency situations. These coatings are typically made from rubber-like materials that can stretch and bend without breaking, making them effective in managing minor leaks and water damage.

Silicone Coatings

Silicone coatings, on the other hand, offer a more durable and long-lasting solution. They can last for many years and are known for their exceptional weather resistance and flexibility. Silicone coatings are highly resistant to UV rays, extreme temperatures, and other environmental factors, which is why they are considered a premium choice for mobile roof repair.

The literature on the durability of silicone coatings suggests that they can last for a "really long time," with no definitive lifespan because they are so durable. In fact, the existing testing methods are not yet advanced enough to accurately determine how long these coatings can last, making them a reliable choice for long-term roof protection.

Aesthetic and Performance Benefits

Besides their longevity, silicone coatings offer additional benefits, such as aesthetic improvements. By applying a layer of silicone coating, the roof can take on a more reflective, white appearance, which helps in reducing the temperature of the building significantly. Before the application of silicone coating, our roof was a charcoal dark grey, which absorbed a lot of heat, leading to higher temperatures inside the building. The white coating dramatically reduced the shop temperature, making it more comfortable and energy-efficient.

Conclusion

Mobile roof repair can indeed be applied over existing roof materials, provided that the existing roof structure is stable and there are no significant leaks or structural damages. The choice between elastomeric and silicone coatings depends on your specific needs and budget, with silicone coatings offering a more permanent and long-lasting solution.

It is essential to evaluate the roof's integrity before applying any coating to avoid future issues. Regular maintenance and inspections can help in identifying potential problems early, ensuring the longevity of your roof. While complete replacement might be necessary in some cases, mobile roof repair can be a cost-effective and efficient alternative for maintaining your roof's performance over time.
