How to Spring Clean a Metal Roof

A good spring cleaning can up your home’s curb appeal and prepare it for the coming summer season.

Many projects that make the biggest impact are easy enough for homeowners to tackle themselves. That’s especially true for homes with metal roofs.

Asphalt roofs can be prone to moss, mildew and fungus and require harsh chemicals to treat and clean. Cleaning a metal roof is often as simple and inexpensive as using plain water.

How to Spring Clean a Metal Roof

Clean your metal roof yourself in five simple steps with this non-toxic recipe.

Clear Gutters

Clean out all gutters and downspouts and remove any large rooftop debris, like branches.

Rinse Away Debris

Before you mix up a cleaning solution, try a garden hose attachment to spray away dirt and debris.

Never use a power washer to clean a metal roof, because the pressure could damage the metal roof’s protective coating.

Mix Cleaning Solution

If water alone isn’t enough to remove dirt and debris, mix a quarter cup of detergent per gallon of water. You can use a mild laundry detergent, car washing soap or mild dish soap.

Don’t add too much detergent to the mix, or it could damage your metal roof.

As always, follow your metal roof manufacturer’s specific instructions to help protect and maintain roof warranties.

Clean Your Metal Roof

Apply the solution to the roof using a washcloth, sponge, soft bristle brush and/or non-abrasive pad. The goal is to use the lightest touch that will effectively do the job.

Never use steel wool, wire brushes, scouring powders, paint removers or thinners on a metal roof.

Rinse Cleaning Solution

Let the solution stand for five to 10 minutes, before thoroughly rinsing the surface with plain water.

Remember, safety is always the most important step for any type of roof maintenance, no matter what the material. Don’t get on ladders or rooftops if you are not comfortable, equipped or well-prepared to take the proper precautions.
