rain gutters

[Mary R.]

How long should it take one man to install about 60 feet of metal rain gutter 8' off the ground? It will have 2 corners and a downspout. Is one downspout on one end enough? There really isn't any good drainage place for a second one. There are trees nearby, so leaf debris would be a problem. Do the gutter screens work well enough to justify the expense, at least under the trees? If so, how much additional time is required to add them? Thanks in advance. M Read
