    Our beachfront home is 16 years old and we were experiencing a number of small leaks in what is quite a substantial roof. We were quoted $250,000 to replace the roof. However our architect recommended that we consider using a guardian seal. Which we did! Total cost was $12,000 and we haven't experienced any leaks since although experiencing some very substantial downfalls of rain. Not only to save $238,000 but the roof looks absolutely fabulous. The service was prompt and efficient. And I would definitely recommend Guardian Seal to anyone else who's experiencing similar problems to what we had.

    Our roof was in need of new life so we decided to have the Guardian Seal team treat and coat it. Boaz and Kaia did a fantastic job. They were hard working, polite and professional. The finish looks amazing and we are very happy with the product, the team and the look.Thoroughly recommended all around.

    The Guardian Seal Coating Process

    1. Clean
    A comprehensive chemical treatment is applied to effectively remove organic growth such as moss, mould, and lichen, followed by high-pressure water blasting to restore surfaces to a clean, pristine condition.

    2. Prep
    Prep - Surface preparation involved mechanical fixes, rust conversion using rust converter, roof and fibreglass patching, silicone sealing, screw replacement, and repairing or replacing broken tiles to ensure long-lasting protection.

    3. Prime
    Prime - As part of the restoration process, we apply a high-quality primer to prepare surfaces for sealing or coating, ensuring optimal adhesion and long-term durability.

    4. Seal
    Seal - To complete the process, we apply two coats of Guardian Seal, creating a resilient, weatherproof barrier that locks in protection and extends the lifespan of the roof surface.
