What Homeowners Need To Know About Metal Roof Restorations
Restoring a metal roof typically involves a series of steps your roofer will perform to clean, repair, and protect the roof surface. Below is the general process for restoring a metal roof.
The Metal Roof Restoration Process
Inspection: Your roofer will begin by thoroughly inspecting the roof for any signs of damage, such as leaks, rust, loose or damaged panels, or deteriorated sealant. They will identify areas that require repair or replacement.
Cleaning: Before applying any coatings or treatments, it's crucial to clean the metal roof surface. The roofers will remove any dirt, debris, moss, or algae using a broom, brush, or pressure washer. They may also clean it using a mild detergent or specialized roof cleaner to remove stubborn stains.
Repairing: Your roofer will address any identified issues, such as damaged panels, loose screws, or rust spots. They will replace or repair damaged panels, tighten loose screws, and treat rusted areas. In many cases, they will also apply a rust inhibitor or primer to prevent further corrosion.
Priming: Once the roof is clean and repaired, roofers will apply a metal primer to enhance adhesion and improve the longevity of the coating system. Application methods and drying times will vary.
Coating: Roofer will apply a suitable metal roof coating to protect the roof surface and extend its lifespan. The coating can provide waterproofing, UV resistance, and thermal protection. It should be a coating specifically designed for metal roofs. Common types of coatings include acrylic, silicone, or polyurethane-based coatings.
Application: Using a roller, brush, or sprayer, the roofers will apply the coating evenly across the roof surface, paying particular attention to seams, edges, and other vulnerable areas. The coating is applied according to the manufacturer's recommended thickness for optimal performance.
Multiple coats: Depending on the specific product, it may be necessary to apply multiple coats of the coating.
Finishing touches: Once the coating has dried, your roofer will inspect the roof surface to ensure that a consistent and thorough application has been made. Expect them to address any missed spots or areas that may require touch-ups and to clean up any drips or excess coating.
Ongoing maintenance: Regular maintenance is essential to preserve the restored metal roof. Speak to your roofer for information about maintenance, which may include periodic inspections, cleaning, and reapplication of protective coatings as needed.
