What Is Commercial Roof Restoration?
Commercial roof restoration is the process of repairing, upgrading, and sealing an existing roof system using advanced coatings and reinforcement materials. Unlike replacement, which removes and installs a new roof, restoration preserves the existing structure and reduces environmental waste.
Steps in the Commercial Roof Restoration Process
| Step | Description |
|---|---|
| 1. Inspection | A detailed roof assessment identifies damage, leaks, and suitability. |
| 2. Cleaning | Pressure washing removes dirt, algae, and contaminants. |
| 3. Repairs | Damaged seams, flashing, or penetrations are repaired or reinforced. |
| 4. Priming | Primer is applied to improve adhesion of coatings. |
| 5. Coating | Reflective, waterproof coatings (e.g., silicone or acrylic) are sprayed on. |
| 6. Final Seal | All roof details and edges are sealed to prevent future leaks. |
