There are a number of different gutter guard systems on the market. When reviewing which type of system might be right for you, you have to take into consideration what type of roof debris your home encounters.
All gutter guard systems can easily handle medium and large leaves. Their size allows the rainwater to wash them right off the edge of the roof. Smaller leaves (less than one inch in width) and pine needles pose a different problem. These types of leaves can make there way into unscreened gutter guard systems due to their small size. Once in the gutters, these smaller leaves can clump together and cause clogs. Then there is even smaller debris like particles from asphalt shingles, pollen and sand that can accumulate on a roof and then be washed into gutters by rainwater. The combination of small leaves and roof debris can really clog a gutter or downspout quickly.
Micromesh gutter guards are especially good in handling an environment with small leaves, pine needles and roof debris. The micromesh screens do not allow this small, fine debris to accumulate in your gutters. Water freely flows through the micromesh into the gutters and then to the downspouts. The angle of the gutter guard is such that this fine debris flows over the edge and off the roof leaving your gutters free and clear.
Before deciding if you need micromesh gutter guards, you should evaluate the area surrounding your house. How tall are the trees (or what is the potential height of the trees)? What types of trees are there? How close are the trees to your house? What type of roof do you have on your home? What other environmental factors are there that leave debris on your roof? All these factors will help you decide if micromesh is the best choice for you.
One other thing to note – if you collect rainwater in a rain barrel for use on landscaping, you may want to consider micromesh gutter guards to keep debris out of the rain barrel.
Taking the time to evaluate your surrounding environment will help you define your needs and lead you to the best choice for your home. This will give you the best results without spending money on a system that is more than you need.
