Fitting a pagoda on a flat roof terrace

[jimny1]

I have a flat roof problem where there was a leak which i now managed to solve
I had the roof terrace retiled , tile over tile, but did not replace the membrane, which i regret , 3 years or so later i had water ingress just in one spot where the water was pooling
So i had it painted with the red waterproof solution and it seems to have cured it , even after the recent storms and heavy rain
The problem is i still get pooling in one spot and have to mop up the water after heavy rain to ensure it is kept dry
So i am thinking of installing a pagoda over this area , i already have one by the pool i got from leroy merlin that had a retractable cloth roof which kept ripping , so had metal corrugated panels installed on it instead using the existing metal frame and use it now to store the furniture during the winter
I am now thinking to do the same on the roof terrace where the water is pooling to keep the area dry and also prolong the waterproofed area
But i don't want to drill into the roof tiles to fix the frame and cause another possible leak
I could fix two of the posts to the adjacent terrace wall which is about 4 ft high , then was thinking the pagoda could go over the top of the roof dome we have that i also use for storage and i am constantly painting as it gets weathered very easily, killing two birds with one stone
The problem is how to fix the other two legs securely without bolting to the floor , there is nothing behind to fix the legs to, only the floor
So i thought i would ask if anyone has had something similar done and resolved the problem ?
I know the answer is to get the membrane replaced , but ripping up two sets of tiles and replacing and repairing the membrane would probably amount to a few thousand euros , this a few hundred, and i would have another covered area for sunbed storage etc
Any advice would be welcome
TIA

Buy a wooden shed and place it over the area then seal the bottom to the roof then you will have storage and problem solved

Thanks Fred , that is another good option , i think i would opt for a metal shed though or similar material as wood needs constant painting or staining, i have the same with a wooden fence
I will have a look at leroy merlin etc and get some prices

Would a pagoda, or a shed fix the pooling? If water pools in an area that suggest the slope of the roof runs down to that area so unless you cover the whole roof, water will still gather under the pagoda, or the shed.

The pooling area is only approximately one metre by one metre S , the base of the shed will cover the area
If the shed base is sealed all around the water should run around the shed and proceed to the drain holes the far wall
At the moment the water stops and pools where there is the slight dip
Since it was painted with mastic it hasn't leaked , but i have just paid over 400 euros to have the walls and ceiling repainted in the bedrooms under this where the wet was coming down previously
Part of the water ingress was due to it being jet washed prior to painting , that forced more water down the cracks to the screed that was spread over the tiles to level it , you would never get that from even a heavy downpour
I found another problem today while i was up on the roof planning the shed idea
There is an air conditioning unit on the wall opposite the wall of the dome , which leaves a narrow gap to fit a shed , probably about 4 feet or so, exactly where the floor dips slightly
So i would have to buy a small width shed , length is not a problem and also be restricted from repainting the wall that side of the dome
It has put a dampener on things, if you will excuse the pun, but still possible
Thanks again for your help S, appreciated
