I know this is a topic i have posted about a lot but it really is such an important topic right now.
I have personally been in this industry for over 20 years while my family have been in it for the better part of 40 years. Needless to say, we have installed external eaves gutters on thousands of houses and have always known that gutters must have provision for overflow. As you walk around any suburban street though, you will notice that most standard house gutters do not have provision for overflow. Why has this been allowed to happen in a regulated and supposedly well-educated industry?
This is an article I wrote over a year ago that shows how long I have been working for a solution.
