Gutter Guard sounds fine in theory, but in practice it doesn’t always work out! Here is another load of gutter guard that we pulled off of a roof. The dirt and dust still gets into the gutters. Leaves can sit on the gutter guard, break down and fall into the gutters. When that is combined with bird droppings, seed and water, grass and other plants can grow. The gutter guard makes cleaning of the gutters very difficult and in some cases it is better to rip the gutter guard out and just clean the gutters regularly.
