Now pay attention to the weight of the gutters.
Overall difference in water volume between 5 and 6 gutter.
It is important because the heavy weight of the water can cause the gutter to sag.
A larger gutter actually will hold more debris than a standard five inch gutter and is not self cleaning.
For those torrential downpours 6 k style gutter can handle a larger volume of water than 5 k style gutter.
In the past residential homes have 5 gutters and 2 x3 downspouts and commercial buildings have 6 gutters with 3 x4 downspouts.
If you want the best performance from your gutters and have a larger roof area then 6 gutters along with the larger 3 x 4 leaders downspouts are able to handle approximately 50 more water than a regular 5 gutter.
The difference is about 50 of the amount of water treated by the 5 inch gutter.
Six inch troughs can hold twice as much water as 5 inch gutters.
Pro s in having a 6 gutter system.
Half round is also a lot more expensive than k style.
Six inch gutter will let the leaves and other debris wash right down the downspout with no need for covers.
Currently we are seeing more residents expand their downspouts to 3 x4 and some even install the complete 6 gutter system.
Able to handle carry more water.
In this round the 6 inch gutters.
K style can handle more water than half round and a 5 k style can handle about much water as 6 half round.
Also the steeper the pitch of the roof the more wind driven rain it will take.
This further decreases the chance for overflow of your gutter even during the hardest of windblown downpours.
With these systems a large load of water can overwhelm 5 inch troughs with their swifter flow rates.
