Default conservatory leak - what does this look like?

Please can someone help me with a suggestion on what to do about
below? (photos at )
We moved into a 10yr old house in Devon 3 years ago. When we've had
both strong rain AND strong wind we get leaks from the conservatory,
seems to be out of the brickwork over the house doors.
Strong rain alone is fine.
We've had the lead flashing where the house joins the conservatory
roof replaced, and it won't leak no matter how much I play a hose on
it.
But if we get strong wind too (we look out over a valley) it leaks
as per the photos .

Someone suggested it's down to rain getting into the bricks and
saturating them so much the water just passes down through the
bricks. I think image 534 and the shininess/dampness of the whole
house face after last night supports this?


No, no amount of rain will soak a brick enough for it to leak through.


Suggestion was to put some transparent waterproof coating on all the
bricks, or insert a drip tray in the brickwork above the conservatory.

I suppose the other options are to let the hedge grow so high as to
disrupt the wind, or get a turbine!
Thanks


Whoever has put the flashing on has made a pig's ear of it.... looking at
the image of the left hand side flashing,(img 0258) it doesn't even reach
the glazing bar at the top near the apex, the opposite side (img0259) is
slightly better, but that too is short at the top.
Aside from this, the entire thing is wrong, the lead flashing you can see,
which is pointed into the brickwork is only part of what should be there -
there should be another flashing running the full length which this visible
bit covers, the piece that is missing can be put in place now, but I
wouldn't use lead if I were you, use a piece of bitumen backed flashband,
about 9 inches wide, this goes at right angles, half onto the roof and half
behind the lead, you can use lead but it will need fixing to the wall
somehow, below the existing lead...there's a diagram he
