Hi Joe,

Don't bother with it, causes a lot of rot through condensation. It also sticks everything together so you can't repair the roof afterwards....cost almost the same as a new roof.

If it was any good, new build houses would use it...

Dont go for spray on foam, it causes more unseen damage, ie condensation, rotting timbers which will be covered and not seen.
Theres not a great difference in the cost of having a new roof.

I agree with mark, dont touch it, if you get broken tiles of slates you have one hell of a job to replace them and when you do you break the seal.

Hi Joe,
Mark is right.
However, if you have an old roof which is in bad condition the foam actually seals and reinforces everything. It is also a very good insulator.
The work can only be done by specialists which is why it is expensive, but you will probably be able to get a grant from the council to pay for most of the work.
