What You Need to Know About Metal Roof Maintenance

How to Safely Wash a Metal Roof

If you purchase your metal roof from Carefree Metal Roofing, the paint on your metal roof panels is baked on a high temperature to ensure a permanent bond and lasting color. However, exposure to dirty air, extreme sunlight, and persistent moisture can lead to dirt, chalking, and mildew deposits, which hide the long lasting paint finish. Simple cleaning can restore the roof to its factory appearance and help you avoid repainting or corrosion.

Cleaning your metal roof is easy: just mix a biodegradable soap such as Simple Green or clear household ammonia with water. For Simple Green, mix one cup of detergent to two gallons of water, and for ammonia use one cup with five gallons of water.

Start from the bottom of the panel working up, and scrub with a sponge, cloth, or very soft nylon brush. Use low pressure water to rinse.

We do not recommend using abrasive cleaners. For mildew that does not come off with ordinary soap (this is rare) use one cup bleach dissolved in five gallons of water.

General Guidelines to Repainting a Metal Roof

Metal Roof Maintenance Tips

Repainting is not generally a part of typical metal roof maintenance, but storm and tree damage could lead to conditions that damage paint. If you need to do any repainting, first follow the cleaning steps above.

For paint repairs where the paint has not exposed bare metal, sand the area gently to create smooth surface.

For painting and metal roof maintenance where some bare metal has been exposed, clear the area gently with hand tools, but do not destroy the galvanized coating. Destroying this coating leads to significantly greater chances of rust even after repainting.

Use the manufacturer’s recommended primer for bare metal roofing before applying the topcoat of paint.

Always be sure that metal roof maintenance or repainting is performed when weather conditions will be stable for 24 to 48 hours depending on the recommendations of the paint in use.
