A Case Study in Roof Restoration: Coastal Roofing and the MantaSil 430 System

This case study examines a classic example of the benefits of applying a roof restoration system instead of a complete tear-off. It highlights the economic and sustainable advantages of this approach, focusing on the successful application of the MantaSil 430 silicone coating system by Coastal Roofing.

The Challenge: A Building in Need, a Budget to Meet

The owner of a commercial building faced a predicament. His insurance company, noticing the deteriorating condition of the roof and recent leaks, demanded upgrades, including a new sprinkler system. The building owner, already facing the costs of these upgrades, was on a tight budget. A complete roof replacement loomed as a potentially overwhelming expense.

Seeking a cost-effective solution, the building owner contacted Coastal Roofing, a reputable firm known for its expertise in roof restoration. Sean Campbell, Sr. Project Manager, and Andy Whitham, owner of Coastal Roofing, assessed the situation and recommended a roof restoration system using MantaSil 430, a high-solids premium silicone coating. This approach offered a compelling combination of cost savings and long-term performance, all backed by a 15-year materials warranty.

The Solution: MantaSil 430 and the 5 Steps to Roof Restoration

Coastal Roofing, confident in the MantaSil 430 system, laid out a clear plan for the building owner, emphasizing the five key steps involved in the restoration process:

Adhesion Testing: Before proceeding, Coastal Roofing conducted thorough adhesion tests to ensure the existing roof substrate was compatible with the MantaSil 430 system. This crucial step confirmed the restoration’s long-term success.
Cleaning: The roof surface was meticulously cleaned to remove dirt, debris, and any contaminants that could hinder adhesion. This involved power washing, scrubbing, and vacuuming to ensure a pristine surface for the subsequent steps.
Priming: A crucial step in the process was the application of MantaPrime 230, a specialized bleed blocker primer. This primer serves several vital functions:
1. Enhanced Adhesion: It creates a strong bond between the existing roof substrate and the silicone coating.
2. Bleed Blocker: It prevents asphalt bleed-through, a common issue with older roofs that can discolor and compromise the silicone coating.
3. Moisture Barrier: It adds an extra layer of protection against moisture penetration.
4. Monolithic look: It will smooth the original roof surface, allowing the final coat of silicone to become more monolithic.
Reinforcing: Coastal Roofing meticulously addressed all critical areas of the roof:
1. Flashing: All flashing details were inspected and reinforced to ensure a watertight seal around chimneys, vents, and other roof penetrations.
2. Seams and Low Areas: To prevent long-term damage, seams were sealed, and any ponding water areas were addressed.
3. Valleys and Waterways: These critical drainage points were reinforced to ensure efficient water runoff.
Coating: Once the primer had cured, the Coastal team applied the MantaSil 430 coating. This high-performance silicone coating provides:
1. Seamless Membrane: It forms a durable, seamless membrane that protects the roof from the elements.
2. UV Resistance: It offers excellent resistance to UV degradation, preventing premature aging and extending the roof’s lifespan.
3. Flexibility: It remains flexible even in extreme temperatures, accommodating building movement and preventing cracks.
4. Reflectivity: Its high reflectivity reduces energy consumption by minimizing heat absorption.
Inspection and Refinement: Upon completion, Andy Whitham personally inspected the roof, ensuring the highest quality standards were met. Any minor deficiencies were promptly addressed, further solidifying the integrity of the restoration.

The Result: A Restored Roof, a Satisfied Client

The building owner was delighted with the outcome. Coastal Roofing had successfully restored his roof and met the insurance company’s requirements while staying within his budget. The 15-year materials warranty provided additional peace of mind, guaranteeing long-term protection and performance.
