Half-round versus K gutters?

[htroberts]

I have a house where the gutters are frequently overwhelmed by the amount of water draining off the roof. It's a 5" K gutter, which is typical here, but a fairly short (12' on each side of an L-shape) gutter drains a pretty large roof area.

The gutters are clean and sloped 1/8" per foot to the downspout. There's only one downspout, but there's also no good place to add another one (for asethetic reasons).

The guy I usually sub gutters to suggested putting on a 6" K gutter, but he couldn't give me any math behind the suggestion--I think that's just the only other thing his machine can make.

The HO and I are thinking of trying a section of these:

and if it works well, replacing the rest of the gutters on the house.

- does anyone have experience with these guys as a supplier?
- how difficult is it to learn to join copper gutters?
- anyone have a picture of a house with white fascia & trim and copper gutters?
- how does half-round compare to K shape for water handling ability?

Anything else a carpenter learning about gutters wouldn't think to ask?

The math is out there on the www - even before in books and guides.

see pg 22 - 23

looks like 5 1/2 round carries half that of 5" K style.

Consider making the single downspout larger.

I don't have one but I think I can get you one if no one else does.

Around here half round gutters are something seldom installed. I have never installed any and they have to be on the right type of house to look right to me.
I would suggest going to a 6 inch K style with the 3x4 downspouts and see if that helps

If my number of downspouts are limited, I go with a 3x4 downspout. They will work on a 5" gutter.

"...(12' on each side of an L-shape) gutter drains a pretty large roof area. ..."

Consider a 'valley shield' where roof valley meets gutter.
'Valley Shield' is standing sheet-metal shape, folded at outside of gutter where valley dumps its concentrated roof water flow.

1/2 round actually carry less volume than K style of the same width, and are more expensive to boot because the brackets and hardware are ornamental and visible.

We install all kinds of gutter and just with the info provided here, I would suggest as others have already to try the 3x4 downspouts.

IMO half round gutter is mainly a looks issue. 5 1/2" round gutter moves less water than a 5" K gutter. 6" K style would probably help, but depending on the house it can look massive.
We install mainly 5" k style gutter with 3x4 downspouts, it seems to work for most applications.
