On more than one occasion I have used drain tracing dye to identify the source point of a leak.

Can involve a bit of time and patience but worked every time.

Back for advice again!
Haven’t been able to do much due to work and weather. Noticed last night that water appeared at bottom corner almost immediately after rain.
Managed to secure a sheet of tarpaulin to top of van and continued to dry out. I haven’t noticed any more water since then so I’m thinking now it may be the roof strap.
Would this be quite easy to re seal during dry weather?
Is it possible to put sealant straight on top of suspect area if it is dry and clean or is it better to work with mastic?
Thanks.

If it is the roof joint seal just putting sealant over it would only be a temporary measure at best, until the seal is remade with mastic, assuming that the panel is okay. Last December my van developed small cracks on the top of the rear panel and they were sealed with white weatherproof self adhesive tape looking like duct tape. It stayed in place and stopped water coming in until the panel was replaced in May.

If you do remove the roof joint strap ensure both surfaces are absolutely clean and dry. Solvents won’t budge the original stuff so elbow grease is the best solution. Use an approved caravan sealant such as
Sikaflex 512 sealant
Ordinary sanitary ware mastic will be a waste of time.
Anyway before any action do your very best to ascertain the source of the leak. Good luck.
