Problem With Metal Roof/gutters

Teetorbilt

My new metal roof provides little resistance to sheeting water and it overshoots the gutters. The obvious is to increase the height of the outer lip of the gutter, do they make gutters like this? The other idea is to make custom standoffs like I did last time but the most that I can gain would only be about 1/2" and that is not going to be enough.

A normal 5 inch gutter I have found to work out ok with most of the products I have dealt with. perhaps your gutter is not as high as it should be. If that doesnt work, then go to 6 inch gutter ( extending the front lip out farther)
If that doesnt work I know one can make a gutter with a higher front. ( the front would be higher than the back )

The only problem I see with a gutter with a front higher than the back is this....I just removed one of these gutters and went with a six inch (wider gutter) because when the downspouts would clog, the water would backup and enter into the eave. The lower face allows for the water to escape over the outside instead of what was happening on my project.

I agree that WIDER is better than TALLER in this case. The other option is placing snow guards which may slow down the water and prevent it from overshooting the gutter.

PGriz explained to me that there are guidelines for metal roofing which dictate that the gutter should be placed a little bit lower than it would be on a shingle roof. Honestly I forgot the whys and hows of the conversation but I am sure he will clue us in.

I believe the writer of the thread is down in Fla. and is not encountering the effects of sliding snow or ice.

pgriz

In the snow belt, the gutters fill up with snow, then with meltwater which becomes ice, and in a relatively short time there is a mound of ice at the edge of the roof that gets in the way of snow sliding off the metal roof. So the outside edge of the gutters on a metal roof in snow country should be lower than the slope line of the roof by about an inch.

In warm climates, where there is no danger of snow sliding off roofs, you can raise the gutters higher, so that the outside edge of the gutters is higher than the slope line of the roof. Then the water will shoot off the roof right into the gutters. The challenge is usually in the valleys, where the flow is concentrated - you may need a guard over the gutters in the valleys to prevent the water from shooting right over the gutter edge due to the volume of water flow.

Some gutter systems that I've seen have a much higher back than the outside edge, which is what I suspect Teeter has. We also see systems that have both inside and outside edges at the same level. I personally don't like these, but perhaps they are what are needed in the Florida situation.

I have the standard 5" gutters mounted to the fascia. Common here, is 'shingle moulding' which is a piece of 1 X 2 attached to the fascia over which the drip edge is placed. In this setup, I have already lost 3/4" of extension plus the additional overhang from the metal roof, another 3/4", and the gutter is about 2-1/4" below the roof edge.

Is there a wide, shallow gutter? I don't want the gutter to be the focal point of the house.

Maybe design yourself some kind of 'spring-loaded' diverter, - - when the gutter takes on water, - - the diverter pops up, - - water stops, it goes back down. Might even be your next million. Don't forget you knew-me-when!!

You can make a gutter in almost any configuration as long as the straps will hold it up.

Teet,

A "T" Gutter Wedge may help.

gutrman

I will give you the link to the product as soon as I hit 10 posts!

Finally! Here it is...

Thanks gutrman, That is perzactly what I was hoping to find. I have the dripedge moulding with angled fascia and when I installed the gutter I cut and painted about 100 wedges to level it. It works fine most of the time but a few times a month it REALLY rains.

Absolutely! Which is why I said "might slow down the water".

In the ski areas, we keep gutters low, so the sliding snow doesn't knock them off. The snow slide sooooo fast down these metal roofs. A lead-coated copper one we did this summer had 2' of snow slide off last weekend......even with low mounted gutters, the slide took out about 40' of high-end half-round copper gutter, some drip and a downspout! Expensive mess!

Teetorbilt,
Steep pitched metal roofs here in Arizona have the same problem because when it rains it really rains. I just tell you what is successful for us. I put a metal lace accross the bottom of the metal panels. It's very decotative and creates a water block for rushing water. This design slows the water flow enough to pour through the lace and into the gutters. The lace is usually as tall as the standing seam.

CGofMP

Scottsdale got a picture of the 'lace' product?

CG, that was MY next question. LOL

How is it fastened?

Sure, I'll get you a picture soon. The lace works kind of similar to weep metal the stucco guys use. It is secured to the standing seam.
