Can anyone diagnose this issue with bricks

Hi 

I asked ea about the black mark above the door. This is response: 

asked about this before and she has had it looked at by professionals a few times and they have said it would have been through hail stones and paint going up it. She has been assured number of times its no concern.

Does this seem plausible. I think the toilet is at other end of the wall so concerned it could be issue.

Not sure how to rectify this either.

Seeing as we don't get that much in the way of hailstones in this country, I'd call out the response as BS.

There is a downpipe on the corner of the property discharging rainwater over the flat roof. If the flashing is defective and/or water pooling by the wall, damp will be setting in. This will lead to mold growth plus a host of other issues. A bucket of bleach will get rid of the worst of the mold for a short while, but unless the root cause is fixed, it will return.

Not 100% clear due to the quality of the photo, but the black mark looks like it is on tiles rather than bricks.

The first thing I'd look at is whether there is a defective gutter join above, with water leaking out and splashing back onto the tiles after it hits the flat roof.  It looks like there is something 'lumpy' in the right place on the photo for a gutter problem to be the cause.

Is there even a downpipe at that end?  The white line seems to go up under the eaves.  Wonder if it was deleted when the extension was added and the gutter now gets overwhelmed

I thought the downpipe is where the hanging tiles abut the area with the windows and white cladding.  There's a fuzzy grey swan neck shape in that position.

I wasn't sure what the white line was, but there is no sign of it having a connection to the guttering.

I'd be more concerned about the area round the downpipe to the right of the door. The brickwork is very green and looks like rising damp.

I would say there is a guttering join above the centre line of the dark patch which is dripping water when it rains and splashing dirt etc up off the roof.

Thanks all, has given me lots to think about. Some more investigation needed I think.

I would say it is all related to guttering, drainage and the flat roof. 

They are tiles for a start, I think it is pooling on the flat roof and splash back is creating damp. Along with a overflowing gutter.

As for all the green, look at where all the water is flowing first it looks like it drains to ground never good way. 

All seem easy fix green and black will come off with a jetwash once the drainage issues solved.

Simple rule all water should be directed away from property as fast as possible.

Thanks for this.

Just found out the road is very high surface water risk as well 

Will enquire about these things.

The green goes most of the way along that wall - so given some of the other maintenance issues I would first be taking a look at the flat roof gutter and the condition of the felt along the front edge of the flat roof to make sure the runoff is getting into the gutter and staying there, rather than dripping onto the path.

It's impossible to tell from the photo, but I would also expect the downpipe to be discharging into a gulley (or similar) rather than straight onto the ground. It could just be that we can't see it on the picture.

I'd also be reluctant to jet wash those tiles.
