Roof Re-Coating – Extend Your Roof’s Life!

What is Roof Re-Coating?

Roof re-coating involves applying a new layer of protective coating over an existing roof to enhance durability and weather resistance. This process is commonly used for flat roofs, metal roofs, and some shingle roofs. Unlike a full roof replacement, re-coating restores the roof’s surface and provides added protection against the elements. Interested to learn more? Read more about roof coating here.

The Benefits

• Extends Roof Lifespan: A properly applied coating can add 10–20 years to your roof’s life.
• Improves Energy Efficiency: Reflective coatings reduce heat absorption, keeping buildings cooler and lowering energy costs.
• Prevents Leaks & Moisture Damage: A seamless waterproof barrier helps prevent water penetration and mold growth.
• Cost-Effective Alternative to Replacement: Re-coating is significantly cheaper than installing a new roof.
• Environmentally Friendly: Reducing roof waste helps minimize landfill impact.

Types of Roof Coatings

Acrylic Coatings

Best for sloped metal and single-ply roofs. Highly reflective and affordable but may wear faster in heavy rainfall areas.

Silicone Coatings

Ideal for flat and low-slope roofs. Excellent resistance to ponding water but more expensive.

Polyurethane Coatings

Stronger and more impact-resistant. Great for commercial roofs with high foot traffic.

Asphalt-Based Coatings

Used for modified bitumen and built-up roofs (BUR). Provides excellent waterproofing but can be heavy and dark-colored.

Signs Your Roof Needs Re-Coating

• Visible cracks, blisters, or peeling on the roof surface.
• Increased energy bills due to poor insulation.
• Ponding water on flat roofs.
• Minor leaks or moisture stains inside the building.
• Fading or chalking of the previous coating layer.

Roof Re-Coating Process

1. Inspection & Cleaning: The roof is inspected for damage, then pressure-washed to remove debris.
2. Repairs & Priming: Any cracks or damaged areas are patched before applying a primer (if needed).
3. Application of Coating: The coating is sprayed or rolled evenly over the roof surface.
4. Curing & Final Inspection: The coating dries within 24–48 hours, followed by a final quality check.

Cost Considerations

Before During and After of Re-Coating Metal Flat Roof

Before re-coating a metal flat roof, it’s crucial to inspect for damage, clean the surface, and remove any rust or debris to ensure proper adhesion. During the process, a primer may be applied, followed by the coating using rollers or spray equipment, ensuring even coverage. After re-coating, the roof should be inspected for uniformity, and regular maintenance should be scheduled to prolong its lifespan and prevent future issues.
