Best cure for a leaky portacabin roof?

jimoc

About 7 years ago I bought a second-hand portacabin.
About 2 years ago I started to get insane amounts of mold growing on the inside walls, made of plasterboard and eventaully tracked it down to the seal that was around the roof on the outside.
It was perishing away and leaving the rain water in.
So I went and got myself a few tubes of silicone sealant and sealed it all.

This year again, the same problem, mostly because the damn birds are eating the sealant off!!!

Should I just resign myself to having to reseal it each year, or is there a more permanent solution?

I was thinking of felt roofing it, but I cant think of how to do that without making loads of holes in the roof or sides.

Any suggestions gratefully recieved.

Hi,

You might look at fitting a pvc coated metal drip detail around the roof, simple enough just a piece of .5 metal L shaped.

The purpose is to protect the silicone, do not fix it through the roof only at face / front of the metal because most portacabins are waterproofed using a pvc sheet which is very difficult to repair.

If you want to use felt you may want to look at fitting plywood sheet over the existing roof because bitumen and pvc do not like each other so you could end up with a worse mess in as little as 5 years.

Hi I am suffering a similar problem and have been quoted an insane amount of 1200 for repairs. Sure it only cost 2000 to buy. Any advise appreciated.
