What Makes A Rain Gutter Cover Good?
Adding a gutter guard or screen can reduce gutter clogging problems substantially, but the way the gutter guard is made greatly influences how well it works. Get the wrong one, and you could end up with more problems instead of making things better. If you're about to buy guards or screens, evaluate them for the following qualities to find a guard that will really help protect your home.
Flexibility sounds like it should be a good quality, but it's not one you want in a gutter guard. A flexible guard is one that can bend under the weight of a lot of debris, and leaves become quite heavy when large piles of them are saturated. If you install guards that are too flexible, the weight of the leaves can drag down and partially block the gutter itself. Instead, look for sturdy, stiff guards that can hold up under the weight of a lot of debris.
Hole Size and Spacing
The guards and screens will all have some sort of pattern at the top where the openings are, and the size of the openings and the space between them can affect clogging and cleaning. Some guards have just the right size of openings to trap tree seeds, which then clog the guards and prevent water from getting into the gutter. Others have openings big enough to not trap seeds, but those also let pine needles fall into the gutter, creating a blockage over time. And yet others have enough space between the top openings to allow leaves to settle on top and block what openings exist. Evaluate the types of trees you have around your home and get a guard that won't be affected by them.
Curvature and Angle
Some guards lie flat on top of the gutter; others are curved or angled so that everything that hits the top falls off. Flat guards can have piles of debris build up quickly, though curved/angled guards aren't perfect - they can contribute to a little more water running off the top of the gutter. If you're getting the guards as a just-in-case protective measure (and you really have no trees looming over your home), the angle might not be as important to you, but if you do have trees nearby, a curved or angled guard is better.
Contact rain gutter contractors and see what styles they recommend for your area. Remember that what worked in one state might not work in another, so if you've just bought your home and moved in from another region, don't assume that what you used at your old home will be the best for your new home.
