How do I protect myself re flat roof?

Other

Hi,

I am shortly going to be renting out a 2nd floor flat with a large window in the lounge which (if you climb out) leads to the flat roof of the flat below.

I do not want to block or limit the window as it would affect the option of using it as a fire exit if the stairs to the flat were blocked and it is a feature of the lounge which is attractive and good for ventilation in summer. But I want to ensure that I am legally protected if the tenants go onto the flat roof and either (a) damage it or (b) injure themselves. It has a raised edge around the roof about 50cm high so is not flat to the edge but I am still aware of the potential danger if they go out onto the roof just for fun!

I was thinking of adding something to the tenancy agreement to this effect and making sure they sign this - some sort of disclaimer? And perhaps putting a laminated sign to the same effect near the window?

Would this be the sort of action you would recommend and can you point me towards any particular wording?

Many thanks,

Charlotte Hayes
