Moss is on most roofs, but it can also get into your gutters. This can cause a huge problem when it comes to gutters being blocked. Moss is very thick and with added rainwater, it can get even thicker due to the fact it absorbs the water. Just because you can’t see any problems externally with your gutter it doesn’t mean that there aren’t any problems at all. Some of the worst damage to gutters are hidden. These may cause you to have a leaky roof or watermarks appearing on the ceiling. Prevention is the best way to fix anything, make sure that you check your gutters every now and again just to make sure that it is in full working order.
