Old caravan roof joint leaks

[Este]

I need to repair the 3 roof joints on my 40yr old Bailey Maru. The trims are not screwed in but nailed! I didn't lift the black rubber seal far but all the nails I saw were of course rusty.

How can I put the trim back on after replacing the mastic when the remains of the nails will be blocking the holes, if you know what I mean?

Can I seal the nail in with something and put the trim back on top and drill new holes for screws?

Presumably you will be fitting new trim. It the wood it sound, it only needs the nails taken down to the surface. Use Sika 522 to fully bed the new trim and fix with stainless steel screws countersunk.

I am not sure where your rubber seal fits. Perhaps pictures would help.

It is quite common practice to install new non corrosive stainless screws into new trim with the holes away from the originals.

Thanks for that. It's reassuring. Are new trims expensive? And do they need to be a particular type or is it by length?

Thanks! I was lead to understand that Sika 522 was not Judy a slant but made a permanent bond offering impossible to remove. If that's the case presumably it doesn't matter that the trim can't be removed if it's done well in the first place?

Can those screws be bought at screwfix or is there a better place? And where would I get new trims from?

Sika 522, (512 as was). Is both a sealant and an adhesive. Most would recommend it.
