Should I Treat My Roof?

[Joey Ramone]

I have a fibreglass roof on a single storey extension. At least I think it's fibreglass.

It has seen a fair amount of weathering over the years we've lived here, with some staining. I tried wet and forget but it didn't really get a huge amount off.

Is there something else I should be treating it with to protect it?

At least I think it's fibreglass

Well make sure of that for a start.

Yes, it's fibreglass.
