I have a flat roof with no wall around the edge, so there is a sheer drop of the edge.
Is it possible to fit railings to the walls that support the roof rather than having to drill through the roof and causing issues with water leaking through?
If you said what your roof was made of it would help alot, come back with details and in the meantime DONT go too close to the edge becase you could have a nasty fall and you might not be found for several weeks.
