Two Gutters Needed?

Hello,

I'm about to begin a garage repair/repaint project. I may need to replace some guttering, but I wanted to run it by those with experience.

My garage has damaged guttering on the north side, and the fascia is ruined as well, likely from the gutter problem. I was going to replace both.

However,

The garage roof ( which is metal ) ends right over a carport, also metal roofed, which has it's own brand new gutter.

Do I need both gutters? Or is it safe to let the water run off the garage onto the carport's roof, and down into it's gutter?

Any thoughts, pitfalls, etc?

Thanks,
Steven.

If there were 2 gutters there, I would leave it that way. You have to fix the fascia board anyway.

I agree with Pulpo, having the water from two separate roof lines empty into one gutter may overpower the gutter on the carport. I would replace the gutter on the garage and extend its own downspouts away from the carport roof so they don't intermingle water.

Also keep in mind the impact of the water from one surface hitting another. It may not be so much an issue with a metal roof as it would with a shingled roof, but any fasters near or at the impact site may prematurely start to leak or rot/rust.
