Has anyone used Leak Proof Spain ?

[jimny1]

I have been searching for reviews but can only find trustpilot reviews for Liverpool in the UK
I managed to cure two small leaks on the flat roof terrace and it has been ok for nearly 2 years
Now they are back after all the heavy rain we have had , small damp patches, one in the bedroom and another in the living room
It was my own fault not replacing the membrane before i had new tiles over the old , but i kept it dry by using a waterproof paint around the drain channel causing one damp patch and the same on an adjacent wall
I don't want to rip up all the new tiles and the old to repair the membrane and replace the tiles , it will cost thousands
So i was thinking of having the rubberised coating leak proof advertise to cover the whole roof terrace , they say it has a 30 year guarantee , i will be long gone before that
Depending on the cost , if too expensive i could get them to do around the two suspect areas
I just wanted to hear from someone who has used them before and were happy with the service
Any advice welcome
TIA
