I have a two story home with a newly installed asphalt shingled roof that also has original "Yankee" gutters. These are aluminum lined gutters built right into the roof overhang. They vary in width from 5" to 6" with depths varying from 3" to 5". I would like to find a way to prevent leaves and debris from clogging them. I have not found any commercial gutter guards capable of doing the job. Any suggestions.
