Flat roof leak - can't find leak?

    My partner has a flat roof with Dryseal fibreglass covering. It was done 5 years ago. The roof is supposed to be guaranteed for 20 years. The Dryseal person says the membrane is fine and it is the velux windows. The leak only occurred since Storm Antonio. My partner found that on one of the velux roof lights, the casing was slightly displaced, and one of the nails in the frame was rusty. There was evidence of a leak stain on one of the velux windows, but it was at the other end of the kitchen, where the kitchen leaked in several places. The other velux window casing was fine but rattled as if it was loose. A service engineer from velux is coming tomorrow My partner power washed the roof including last week and at the side of the velux windows but no water came in. Last night was a dry night, but this morning we came down to the same area leaking again and then a new small leak - at the other end of the kitchen to where the Velux had a stain, but near to the velux which looks fine. Do we need a thermal imaging camera to detect the leak, and if so, what is the likely cost of this? We wondered if there were central heating pipes going across the ceiling - my partner heat the water with gas - when the leak occurred today after it being dry last night. Any suggestions and advice welcome - my partner is stumped by this.
