Does anyone know anything about roofs, I'm in need of some (informed) advice please specifically about this spray on roof insulation that seemingly fixes all problems (mine leaks when windy).

Apologies this is nothing to do with model cars. I read as many positive reviews as bad ones it seems so really not sure what to do.

Can we avoid jokes in this please as I'm a little stressed about this.

Any help/expreriences much appreciated!
