As I write this, torrential Gulf Coast rain is flowing off the roof and
overwhelming my recently cleaned 6" Cu gutters creating a mini waterfall and
putting water into the nearby garage.2 gutter men have advised that gutters
come no bigger than 6".True?
You need more downspouts. One at each end is a start. In bad areas
where a lot of water goes over the gutter a 3" high pice of matching
metal can be added. This does not look great on the front of a home
but everywhere else should be ok.
The link does not carry any gutter larger than 6", what are you talking
about? BTW, 6" is commercial size, there isn't a need for anything larger.
Sufficient down drainage sounds like the problem, maybe undersized downs or
like already mentioned, not enough downs.
There are 7" & 8" half rounds on that page when I go that link.
Though I'm not sure a 8" halfround carries any more volume than a 6"
I'd be looking in that direction myself. I'd probably want to add a
downspout if possible unless these are going directly into a gutter or
sewer system. That's a lot of water to dump around a foundation.
In a previous posting, Usenet was endowed with the following text from
Gutters come in many sizes. 6" gutter is a standard. It doesn't mean
that it's the only thing that should be used. However, larger gutters
alone will only increase the gutter capacity, not the drainage capacity.
More, or larger, downspouts will increase drainage capacity.
your problem must be the downspouts. are you using the correct size,
4"? if 2x3 leader more than 20ft apart, you might be overwhelming
I've seen plenty of commercial flat roofs, which drain here into this
size gutter without a problem. there is no larger *standard* size
gutter. you have commercial size now. any larger, which can be had,
will look terrible. I've see larger ones on prefab metal buildings.
they are LARGE and look Terrible.
