Re-doing gutters from flat to sloped.

So Iím re-doing my gutters.
they are currenlty flat, basically tucked up right up under the shingles.

i donít have any gables on the house, so itís basically 140 ft of a continuous gutter, with 5 outside corners, and 2 inside corners.

My concern is that if I keep 1/2Ēslope for every 10 ft, that eventually runs the gutters right off the 5.5Ē of fascia.

so my question is it better to break up the gutters into sections so I can have an appropriate slope in each section, or to keep the flat system, or does aluminum k style gutters have enough flexibility that I can sort of slope up and down as I go and keep a continuous gutter system.
thanks in advance.

1/2" in 10' is an unreasonable amount of slope. Professional gutter installers give seamless gutters a barely perceptible slope.

You dont need slope on gutters, nothing looks worst than a long run of gutter that slopes from the drip edge. Looks like a cheap install!

Water will find it's level, a little pooling of water will eventually evaporate!

Why do you think you need slope?

I guess I thought I needed slope because of all the videos on YouTube that said I did. I realize that may not be a reasonable argument, and the current ones seem to be draining ok, so thatís another reason to post here, to get opinions that are different than what I had.

I disagree with Marq.
My daughter's house has the exact same problem. And I need to fix it. Water should not lay in the gutters due to not enough slop. Big problems can occur. One, debris can more easily collect, causing dirt to stay and eventually seedings will grow. I just removed over a hundred tree seedling from her lower section, preventing water flow. Two, that amount of weight can cause the spikes to loosen. And if you're located in a northern climate freezing water will eventually damage the gutters, and add weight as more rain and snow and ice builds up. Water lying in the gutter will erode any connections and leak, and eventually rot the facia board. Even though they might be continuous gutters, corners are still a separate piece. Every one of these condition are an existing situation on my daughter house. So I know what I'm talking about. And if you have trees, blockage and cleaning becomes a regular routine maybe up to 3 times a year. So slope is very important. I've seen houses where the slope is very obvious. But it does not take away from the looks of the house. In fact if you are aware of these problems, a house that does not show a slope looks odd.

So that is an issue separate from water collecting which around 1/8".

Debris collecting in the gutters needs to be resolved by keeping debris out, covers or foam (another lively topic)!

You can install slope, it's not going to hurt but it's just a terrible visual

Just got back from daughters house. Cleaned upper story gutters. Installed gutter guards! My knees are burned, legs and stomach hurt from laying flat on my belly at the edge of the roof two stories high. Should've worn long slacks or jeans. This fix will last her about 2 to 4 years but I told her she must get new gutters and have them re-routed properly and installed by a reputable firm. What's on there were not properly sloped. Some of the facia boards are starting to rot and some of the seams are leaking. But at least now the water will go down the drain pipes and not over the gutters.

You did not say how many downspouts you are having.

You will need more than one for sure.
