Does the roof fall away from the wall/corner where you get the water marks inside? ESSENTIALLY THE FLAT ROOF POOLS ON THE NEAR SIDE OF THE PICTURE. THERE IS LIMITED SLOPE BUT TO ANSWER YOUR QUESTION YES I THINK IT DOES.
Does it leak every time there is an good amount of rain, or only sometime? ONLY SOMETIME. I WAS CONFIDENT IT WAS WIND RELATED TO START WITH BUT IT CAN BE SUPER WINDY AND NO LEAK AND THEN VICE VERCA
What is above the wall, is the gutter in good condition? THE GUTTER LOOKS IN GOOD CONDITION TO ME. IVE INCLUDED A PIC BELOW
As it is a kitchen below, is that causing condensation? NO THERE IS NO CONDENSATION ON THE SKYLIGHT OR IN THE CONDITION
How is that pipe sealed to the roof? THE PIPE IS SEALED AS IN PICTURE BELOW
What are all those circles in a line, bolts/screws? I AM NOT SURE THE PICTURE I HAVE SHOWN WAS ON A COLD DAY I WILL INCLUDE ONE ON A NORMAL DAY BELOW> I WILL ASK MY ROOFER TOMORROW THOUGH.
Sorry for caps but felt the best way to respond to distinguish my response from your question
cheers
