I am looking at replacing a downspout and possibly some gutters. Currently I have the usual rectangular white aluminum downspouts and gutters.
My concern with those is that they have limited capacity, so in heavy downpours they can overflow. Also, they are kind of flimsy.
Are there better options that would represent an upgrade disregarding cost?
Several options I have thought about are: clay pipe for the downspouts, copper gutters and stainless steel gutters. In Europe I have seen clay/terra cotta downspouts, but in the US I do not see them. Is there some practical reason why they should not be used?
