Six inch troughs can hold twice as much water as 5 inch gutters.
Overall difference in water volume between 5 and 6 gutter.
K style can handle more water than half round and a 5 k style can handle about much water as 6 half round.
Pro s in having a 6 gutter system.
Half round is also a lot more expensive than k style.
The difference is about 50 of the amount of water treated by the 5 inch gutter.
In the past residential homes have 5 gutters and 2 x3 downspouts and commercial buildings have 6 gutters with 3 x4 downspouts.
In this round the 6 inch gutters.
Currently we are seeing more residents expand their downspouts to 3 x4 and some even install the complete 6 gutter system.
It means that the gutter will not be overfilled during periods of heavy rains as there is enough space inside the gutter.
To find out that is better the weight of the dimensions considered should be compared when both gutters are filled with water.
Also the steeper the pitch of the roof the more wind driven rain it will take.
For those torrential downpours 6 k style gutter can handle a larger volume of water than 5 k style gutter.
Able to handle carry more water.
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.
A larger gutter actually will hold more debris than a standard five inch gutter and is not self cleaning.
But even among k style aluminum there is a wide range of choices mostly regarding thickness which ranges from 019 to 032 but also on finishes.
Now pay attention to the weight of the gutters.
