Every house must have gutters to drain rainwater from the roof to the floor and protect it from structural damage. It is perfectly normal for these channels to become clogged with leaves or other debris most of the year.
Instead of doing a difficult and dangerous cleaning, you can install gutter guards or gutter shields. These covers should do a great job, but you have to carefully decide which ones they will actually do.
Here are some tips on how to find the best gutter protector.
Check how well the cover protects the gutter from leaves and dirt. Most systems don't allow leaves to penetrate, but some can't handle twigs and pine needles in particular. You need to make sure that the lid itself is not blocked by the debris.
It is good to look for models with small holes or models with slots in a narrow channel covered by a rung type. You need to make sure that the gutter guard has a high water flow. This ensures that rainwater does not overflow from the roof and cause damage.
It is difficult for you to measure the flow of water on the roof by looking at it. This is why you should ask the contractor or business for details. Most good systems have been independently tested and their water flows measured.
