Downpipe draining into vent

[george121212]

Hi just had new soffits and down pipe installed.

A new downpipe has been installed what looks to be draining directly onto what appears to be a roof vent? I suspect the vent could be linked to the extractor fan or venting to extension void.

A little worried water is draining over this vent and going to go straight in?

Would be grateful for your thoughts?

Note: I'm not a roofer, just my diy level opinion!

If that's a vent of any description (for fan or general roofspace ventilation) it will be designed to repel water ingress. Imagine a scenario where it's raining heavily for an hour with heavy winds blowing rainwater this way and that. The vent has to repel most/all of that water. So in theory, water running down from the drain shouldn't be a problem. If however the vent isn't a proper vent but something the roofer has cobbled together themselves then it's more difficult to comment.

If you want the drain to miss that area altogether, would it be possible to have a 90 degree joint put in a bit further up the downpipe, with a horizontal piece maybe 18-24" long, then another 90 degree joint leading down to the shoe (end piece.) Essentially, moving the exit point for the water along the roof by 18-24"? Wouldn't look as good as the straight downpipe but might put your mind at rest?

Others on here will be along to advise.

Is the new Downpipe in the same place as the old one?

Hi thanks for the helpful replies.

Prior to this there was no downpipe there.

I like the idea of moving the exit 2 foot to the left.

I suspect the vent might be up for the heavy water but not worth the risk.

Move the rwp the vents will be overwhelmed.

Use an offset and short length of d p.

The rosemary tiles below the outlet look as though they have been jammed in with a broken piece of tile.

Would I be able to climb on the roof myself would the rosemary roof hold my weight and do this perhaps going up on the hip tiles?

Better to move outlet around corner to rear to discharge onto rear roof ?

Thanks for the comments installer is coming back to amend as only completed the job last week. Out of interest why would it be better to discharge onto the rear roof?

Where Foxhole is possibly coming from is, rather than muck about with an offset on the existing side, just do a straight downpipe around the corner, will look neater and totally avoids the roof vent.

An offset will miss the vent, cost £2.00 and take 5 minutes or less
