What is the best metal roof coating for your commercial building?

The best metal roof coating for your building depends on its current condition, the local weather, and your budget. There isn't one "best" coating for every situation, but Conklin-trained contractors can recommend the right metal roof coating system after an on-site inspection.

Symptom

You see rust spots, leaks, or faded paint on your metal roof. Maybe fasteners are popping up, or seams are pulling apart. You might also notice your building's cooling costs are higher than they used to be, or your tenants are complaining about inconsistent temperatures indoors. Basically, your metal roof isn't doing its job like it used to, and you're worried about bigger problems down the road.

Problem

When a metal roof starts showing these signs, it means its protective layers are failing. Rust weakens the metal, leading to holes and leaks. Leaks damage whatever is inside your building, including insulation, inventory, or equipment. They can also lead to mold and structural problems. Loose fasteners and separating seams are open invitations for water to get in. If your roof is dark and absorbing sunlight, it makes your AC system work harder, wasting energy and money. Ignoring these issues means the problems will only get worse, eventually requiring a full roof replacement, which is far more expensive and disruptive than addressing it early.

Solution

A commercial roof coating system can restore your metal roof and extend its life, often for many years. It stops leaks, prevents further rust, and reflects sunlight to save on energy costs. Here's how it generally works with a Conklin roof coating system:

1. Inspection: First, a Conklin-trained contractor will inspect your entire roof. They look for rust, loose fasteners, open seams, and damaged metal panels. They check the condition of the insulation underneath. If the insulation is wet, or the metal deck is too far gone, a coating might not be the right fix. In those cases, they'll tell you honestly what needs to happen.
2. Preparation: The roof is cleaned thoroughly to remove dirt, rust, and loose paint. Sometimes a power wash is all it takes; other times, more extensive rust treatment is needed.
3. Reinforcement: Any loose fasteners are tightened or replaced. Open seams are sealed with a durable fabric and a special base coat. Rust spots are treated and primed. This step is critical for making the roof watertight again.
4. Base Coat: A protective base coat is applied over the entire roof surface. This layer adheres to the existing metal and prepares it for the top coats.
5. Top Coats: One or more layers of a highly reflective acrylic top coat are applied. These coats are seamless and flexible, expanding and contracting with the roof in changing temperatures. The bright white finish reflects most of the sun's UV rays, keeping the roof surface cooler and reducing the heat transferred into your building.

This process creates a new, waterproof, and energy-efficient surface over your existing metal roof. It avoids the mess and cost of tearing off the old roof and sending it to a landfill. It's a commercial roof restoration that makes your roof like new, often with a long-term warranty.

Frequently Asked Questions

What types of metal roofs can be coated?

Most common commercial metal roof types can be coated, including R-panel, standing seam, corrugated, and flat metal roofs. The key is that the roof structure must be sound and the existing insulation dry. If you're unsure, an inspection will confirm if your roof is a good candidate.

How long does a metal roof coating last?

A properly installed Conklin metal roof coating system can last 10 to 20 years or even longer, often backed by a non-prorated warranty. Its actual lifespan depends on the specific system installed, the local weather, and how well it's maintained. The good news is that when the warranty period is up, the roof can usually be recoated again to extend its life even further.

Will a coating really save me money on energy bills?

Yes. The white, reflective surface of an acrylic coating reflects up to 85% of the sun's heat. This keeps the roof surface and the building interior much cooler. Many building owners report significant savings on their cooling costs, especially in warmer climates. Think of it like putting a white shirt on your building instead of a black one on a sunny day.
