Gutter Leader Heads, also referred to as conductors, or collection boxes serve a practical, as well as aesthetic purpose.
On large roofs, or roofs with particularly steep slopes, gutter leader heads can prevent water from overflowing at the corners. Without leader heads, the downspout could fill with water, blocking out air thereby creating a vacuum which prevent the water from flowing.
For the typical home, in your typical geographic area, your gutters and downspouts will function perfectly fine without adding a conductor head to it. Yet some still prefer to add leader heads due to their aesthetic appeal.
At Royal Gutter Supply, as your one stop gutter supply shop, we carry a variety of Leader Heads in over painted aluminum as well as copper. In stock and ready to ship.
