Just sitting watching a thunder storm and the water is coming off our roof
so fast that it is flying straight over the guttering and into the rather
startled bamboo plant.

Made me wonder if there is something ready made to clip to the edge of
half round guttering to deflect water back into it.

No rain for a month and then it all comes at once.

Oh, the main roof drains onto the sloping roof over the extension and then
into the guttering around that.

I have a high level downspout that discharges onto a low level roof
and in heavy rain, that did overshoot the low level gutter and end
up running down the wall.

I took a 2' offcut of gutter and cut it lengthwise along the middle
forming two quarter rounds. One I glued as an upstand to the inside
surface of the outer edge of the existing guttering (using PVC solvent
weld) with the top edge curved towards the roof, and the other piece
is resting under the tile edge and felt curving down into the gutter
(acting like a felt support tray - I'll remove it when I get around
to fitting proper felt support trays along that roofline).

That has worked well for ~30 years now.

This solution was for just a short section of the gutter. If you have
water overshooting for much of the length, then the gutter is probably
positioned wrongly with respect to the tile edge.
