Our Fiber Glass Roof Installation Process

1

Surface Preparation

We thoroughly clean and prepare the substrate, ensuring it's dry, sound, and free from contaminants.

2

Resin Application

We apply the first layer of catalyzed resin to create a strong bond with the substrate.

3

Glass Mat Installation

Glass fiber matting is carefully laid into the wet resin and thoroughly saturated.

4

Additional Layers

We apply additional resin and mat layers as required for the specific system specification.

5

Top Coat Application

A UV-resistant top coat with aggregate is applied for protection and aesthetic finish.

6

Curing & Inspection

The system is left to cure completely before undergoing rigorous quality inspection.

Fiber Glass Roof Maintenance

Proper care ensures your fiber glass roof lasts for decades

Regular Inspections

Conduct visual inspections twice yearly to check for any damage, blisters, or wear.

Keep Clean

Remove debris, leaves, and dirt regularly to prevent moisture retention and potential damage.

Ensure Drainage

Keep gutters and drains clear to prevent water pooling on the roof surface.

Trim Overhanging Branches

Prevent damage from falling branches and reduce debris accumulation on the roof.

Address Repairs Promptly

Fix any minor issues immediately before they develop into major problems.

Professional Maintenance

Schedule professional inspections every 3-5 years for optimal performance.
