Roof Cleaning questions, answered by experts

To prep for metal roof painting, have a roof inspection conducted to determine the condition. Complete any repairs required before you paint. Remove the old paint on your metal roof, if any, remove rust and mold with a wire brush, and power wash the surface. Once the roof is clean and dry, start with a primer get painting.

You can rinse your solar panels in some cases. For example, periodically rinsing your solar panels can remove light debris if you live in an agricultural or dusty area. Light dust and dirt won’t affect efficiency much, but they can build up and mix with other debris like animal droppings, leaves, and small sticks. 

It is a bad idea to try to walk on a roof with snow on it. In fact, you should stay off your roof all year long, even when it is dry and sunny outside. There are too many things that can go wrong, and one misstep can cause serious injury or even death.

Rather, if you need to get something done on your roof, call in a pro. They have the right experience and know-how to get things done safely on a snowy roof, including snow removal.

Soft washing chemicals typically consist of a mix of sodium hypochlorite (or a chemical component of bleach) and water. While sodium hypochlorite and bleach are often thought to be the same thing, there is one small but key difference between the two: sodium hypochlorite comes in powdered rather than liquid form, which means that it’s also more concentrated and more effective from less product overall.

Other than it looking like a dirty car, there are some other signs you need to clean your roof. Moss growth, algae (often black streaks), grime buildup, buildup under shingles, and leaf buildup are all classic signs a cleaning is overdue. If you have neighbors, take a look around. If your roof appears different in any way, that’s another sign to call a pro to have it cleaned.
