Hi. Bet im asking a question EVERYONE has beat to death already BUT here goes...I Recently had a $40,000.00 metal roof installed over top of our asphalt shingle roof. It's a rustic metal style shingle on all the pitches but a straight flat metal on all porch roofs. (BEAUTIFUL) Now, When the rain lands on the rustic style metal shingle it hits the gutters fine. Smooth, as it should. But as rain slides/runs down the straight flat metal roof it over shoots the gutters. Especially during heavy down pours. This is currently happening in two areas. Over the garage and back patio/porch. Water collects quickly below as it over shoots these areas, quick enough that I've got a flash flood situation at times. Scary feeling...I worry about water in our finished basement now. There are signs that its getting in. So...how do I solve this problem? French drains? No, how about the roof??? As I said, the rustic style shingles distribution of rain into our gutters is fine. The problem only arises from the flat metal portion, over shooting horribly. The Roofers did nothing with the gutters that were already on the house. No tweaking of any kind and no mention of any possible problems we may have with rain. They did suggest snow/ice thingys, whatever they're called, but we passed on those as of now. RAIN...that's our current problem. Help... Thank you for your time.

Thanks for buying a metal roof. It does look great. Normally my suggestion would be to mount the gutters as high as possible. I see the gutters are sloped from the left to the right. Is the over-shooting of the gutters any better on the high left end of the gutter than it is on the low right end?

+1 Gutters can be moved up with brackets and perhaps the next size up gutter (i.e. 6") will work better here.

It looks like your existing gutters were installed with spikes and ferrules at 3'0" on center. This winter you will find your gutter on the ground if you did not install snow guards. I recommend you install a 6" k style with concealed hangers 16" oc with two screws each. Then you probably do not need snow guards. Heavy summer rains will probably always overshoot the gutters, but the volume of water should not be a problem if the landscaping slopes away from your home. thanks for installing a metal roof!

Our home has a metal roof but no gutters. We are in a low snow area but in times of heavy rain the basement leaks. Would we help ourselves with gutters or are we doing more harm than good?

Gutters can be a great way to get water away from your home's foundation. I would echo the above comments in terms of installing a heavy duty gutter with fascia brackets screwed into every rafter tail. I also suggest mounting the gutters high rather than low.
