It sounds like moss is constantly falling from your roof onto your car, driveway, or patio. You're concerned about the potential damage moss may be causing to your roof, and you’ve noticed your gutters getting blocked more often due to moss buildup. Not only is moss a nuisance for homeowners, but over time, it can cause significant damage to your roof and property. When temperatures drop, freezing moss expands, gradually enlarging the tiny cracks where the moss is embedded, which can lead to broken or cracked roof tiles. Moss also easily clogs gutters, causing overflow that can result in dampness and even mold inside your home. However, it's important to choose the right roof cleaning method, using the wrong techniques can do more harm than the moss itself.
