Hot tub on roof terrace?
Discussion
What checks would I need to do before putting a hot tub on the roof terrace of my new flat? It's a converted factory with a decked roof terrace, the decking has enough support to handle the weight but I have no idea of the construction of the flat roof area underneath... any advice welcome.
Oh and yes I fully intend to use it with those of the fairer sex, any jokes, perversions, and most importantly ideas are more than welcome

Loads of checks to do.
Does your lease permit this?
How are you going to get water to it, and from it? Is the hot water system man enough for the job.
The construction of the roof will need to be checked by a structural engineer. That may involve investigations at the local authority to determine the construction, and may involve intrusive investigation on site.
The weight of hot tubs is potentially very high and the roof may need strengthening.
FAR from straightfoward, and she must be a cutie to justify that amount of effort. Cheaper to take her to a spa for the day and 'bash her back doors in' (which I believe is the favoured PH foreplay technique) in the changing rooms.

Back doors serviced thanks (lad etc etc)
Sod the lease, I've only got a 2 year extendable lease on the place (rented obviously). I'm now thinking more of an inflatable one anyway just for convenience, they're self heating, removable and weigh less. There's a tap on the roof terrace and the drainage is good so I guess theat leaves:
Structural engineer, reckon the weight will be about 1.5t when full. Not too bad but bad enough to cause disaster if I chance it without getting it checked properly

You sure of this, 1 cubic meter of water weighs 1000kg, so either is really small or you may want to work that out againETA seems a small one is about 1300kg and a large one 3200kg,

If Its a relatively new conversion it should be fairly straight forward to check the construction.
Phone your L.A. and speak to Building Control. Ask them to dig out the application for the conversion. Then go and visit the L.A. offices. This will save you fannying about waiting for the file. Trust me!!!!
As its a public file you can get copies of whatever you need (at a charge). Then speak to an Engineer on the feasibility!
If you do go ahead then post pics of afore mentioned hottie!
ITS THE LAW!!!!!

Just to be a nerdy surveyor for a moment, you're right, head for Building Control, but they may not give you a copy of information they have on file, although you can look at it if you have sufficient interest and a note of authority from the building owner. You can make notes of what you see, but some won't give you copies, citing copyright and all sorts of old bollix. Unless you know what you are looking for that will be no use at all.We have come up against this a couple of times recently and they wanted permission to relaese from the original architect. Planning drawings are different are are a matter of public record.
Having said that, best bet is to make an appointment to see the Building Control Officer and explain what's involved, he will probably look things out for you and will probably give you what you need, thus avoiding the jobsworth administration nazi's!
OP: You say that the drainage is ok. It's ok for rain falling on the roof, and will be designed for a 1 in a 100yr storm or something. Empty a hot tub too quickly and it'll be a biblical storm.
You can't just ignore the lease either. The chap you are renting from is holding the lease and you'll be on streets toot sweet if he finds out and hasn't given permission.

My money is on the the fantasy being replaced by the reality of too much red tape; resulting a Thomas the Tank Engine paddling pool, fish tank aerator, and not quite as many honeys as first expected.
and me in speedos being the picture?The only planned honey is the current bird (if she's around long enough)... and some of her mates, it was their idea tbh. You may well be right about the red tape but it'd be plain wrong not to try.
Herbialfa - It is quite recent, thanks for the advice.

I realise the drainage will need to be done slowly and gradually, but thanks. In terms of the lease, I'll go through the red tape 1st, if it's possible without any alterations I'll approach the owner. If it becomes too much like hard work I won't have bothered them thus avoiding any hassle.You can't just ignore the lease either.

The small inflatable lay-z spa's are 900 litres thus 0.9 tonnes, so using my unprofessional opinion i'd say its fine. What's the worse that could happen....
Oh there is plenty that could happen. You are aware of the duty of care you hold when offering advice? Unprofessional or not.I would be very careful. Much depends on the construction and design of your roof. That spa is 9/10 of a ton and is about 5 bathfull's. It's not so big in terms of area it sits on that you could consider it anything other than a point load.
It's quite probably going to be ok, but make no assumptions and get it checked per the advice up there ^^^^^^^^^
