How To Clean Metal Roofing

Your roof is exposed to a great deal of wear and tear due to various weather conditions throughout the year, and thus it is only natural that the finish on your roof should start to fade or wear away with time. Even metal roofs are highly durable and stand up to weather exposure much better than their wooden or asphalt counterparts, they too can begin to look a little battered and beaten over time. Thankfully, if you want to clean your metal roof and leaving it looking good as new, there are a few simple cleaning techniques that you can use.

Corrosion

If your metal roof has begun to corrode, don't panic. Corrosion and rust can be a major problem if left untreated, eating through your roof and letting water seep into your home. However, if you catch it early enough, you can fix it fairly easily. Simply use a wire brush to scrub the corrosion away, brushing lightly so as not to damage the surrounding metal and paint. If the corrosion does not go too deeply, you can simply paint over the scraped area. If the corrosion has eaten through the metal, you'll have to replace that panel as soon as possible.

Dirt and Debris

Dirt and debris can be easily and quickly removed from a metal roof using a pressure washer. Simply start at the peak of the roof and spray downwards, so that the water will flow into your gutter system and drain properly. If need be, you can use a solution of water and mild cleaning detergent if the dirt is particularly stuck on. In order to proactively reduce the amount of detritus and dirt on your roof, you should trim back any overhanging trees or shrubbery.

Mold and Mildew

If mold and mildew have begun to grow on your metal roof, you should remove as much of it as you can by hand, and then use a cleaning solution to disinfect the area. Avoid using a mixture that has bleach in it, no matter how diluted, as bleach will cause your metal roof to corrode. Instead, use a common household disinfectant dissolved in water, or for serious cases, a half cup of trisodium phosphate (available at most hardware stores) mixed into a gallon of water. Simply scrub down the infected area and remove any stuck on mold, and then rinse it down with a normal garden hose.
