Advice for heavy/fast rainwater missing my guttering

spoony77 · 28 Jun 2020

Hi people
I have a pitched roof on a rear extension and the guttering from the main house emptys onto one of the tiles and down the groove to flow down this pitched roof and into the new guttering of the extension.
This seems to work but when the rain is heavier than normal the flow of water is so fast down the tiles that it cascades at a rapid rate straight past the guttering onto my patio below.
Is there a way I can maybe glue some sort of back splash to the guttering to catch the heavy rain flow and divert it back into the guttering?
Hope this makes sense :/

There are lots of different ways to slow the water down such as some lead, or angling some pipe across the roof rather than straight down or cutting the pipe differently etc. have you got a picture of the setup?

Thank you for taking the time to reply.

Looks like it’s already got a head start flying out of the shoe and perhaps it’s discharging over the end course of tiles. Firstly the pipe could do with coming across to the left a brick width and it’s length extended so the shoe is almost resting on the tiles. You’ll find the water running down this new channel might help as the bottom tile on the right kicks up a tad sending it over the lower gutter. Do this first and then you can think about a piece of lead or plastic wedged in the lower gutter.

You could try and move the small section of gutter up to the tiles by uncliping it and highering the bracket and then clipping it back in.

as above move and lengthen short downpipe. It looks like the gutter could be raised too.

Thanks guys, very helpful.
If I buy then a couple of square right angles and a short length of square downpipe this will suffice, as in its just push fit, no other connections or sealant needed?

You will need a pipe connector and bracket to fix it to wall if you are extending the pipe.
All push fit no sealant required.
