Gutter overflow in heavy downpour - overflow protector?

rossyl · 19 Aug 2021

Hi

Firstly, gutters are 3 storeys up, I don't ha e a ladder, nor head for heights to fix this myself.

Water comes off a large gable end, rushes down, hits the gutter, then the water splashes over the edge of the gutter.

The gutter is half round plastic.

(note this only happens on one side of thr gable, on the other side the normal half round plastic gutter works fine)

The gutters were recently cleaned, I saw photos, they thought this was the issue as well.

I've seen metal "overflow protectors" that sit on the side of the gutter.
I think a steel overflow protector might be bit too heavy on a plastic gutter.

Thoughts?

Also any other ideas to stop this from happening, appreciated.

Thanks

Gutter might be in the wrong place (often happens when old cast iron is replaced with placcie, the cast brackets had a long spike on them.
Gutter might be undersized for the roof given the recent tendency for heavy rain rather than persistent drizzle.
Lead upstand might work (but if the brackets are too far apart the gutter might sag).
You paid for the gutters to be cleaned- were they? Is the downpipe blocked or restricted?

Down pipe is clear
Gutters are clean

I am sure of both.

The rest has question marks. No idea when the plastic replaced the iron.

But looks like this has been a problem for a while given the walls

Aluminium sheet wouldn't be much heavier than plastic, held in place by polymer type mastic and a couple of self tappers or perhaps a piece of upvc sheet? You cant go too big or the wind may catch it and bring it all down with disastrous results.

Alternatively what about something fixed to the roof to divert the water flow and slow it down before reaching the gutter?

You could use a piece of the same guttering you already have and glue it inside using some polymer as suggested by old salt but raising it up to the desired height on the outside edge.

Thanks.

Trouble is trying to build it on the ground, then making sure it doesn't foul the clips when trying to seat it.

Junior hacksaw to cut the top off any gutter bracket that might be in the way.
