The average cost to clean a roof is around $500, but prices can fall between $150 to $1,000 or more. The size and complexity of your roof are the most significant cost factors, as larger roofs and those with various bump-outs and gables will increase your cost. Your roof material will also make a difference. An asphalt roof will require more labor, as your professional will need to be careful not to damage the shingles. A metal roof can stand up to more intense scrubbing and shouldn’t take as long to clean.

You may become so frustrated with the look of moss on your roof that you contemplate whether to clean or replace your roof. Fortunately, you don’t have to go as far as replacing it. After cleaning the moss, you can use a chemical solution to keep it away. For further protection, trim branches that overhang the roof, as fallen seed pods and leaves on the roof allow moisture to collect, encouraging moss growth. Consider adding zinc-coated flashing to the roof, too. As rain washes across the zinc, it leaves zinc particles behind that inhibit moss growth.

While it is possible to remove snow from your roof without a professional, we don’t recommend it. Accessing your roof can be a dangerous task; pair that with slippery ice and snow that can be heavy to move, and you have a very risky problem on your hands. This dangerous situation becomes more high-risk when there’s a snowstorm or your roof has a steep pitch. To ensure that everyone stays safe, be sure to call a roof snow removal specialist to complete this job with the proper tools and equipment.

Leaving a significant amount of snow on your roof can be risky. Most roofs are designed to handle about 20 pounds per square foot of snow, but exceeding this limit can lead to a roof collapse. A collapse can cause severe damage to your home and belongings and poses a physical danger to anyone inside. Furthermore, heavy snow accumulation increases the risk of ice dams, which can cause leaks and water damage to your roof, attic, and interior walls.
