Rooftops, you are a salesman. Do you do a line in gazebos?
Maybe not a daft question, but I reckon one would be daft doing it!!
3 reasons:
1) Wind
2) Rain
3) Snow
If you need one, then erect when needed!
1) how long will it last? Wind will go under it anyway, unless you put it up at half-height! (you will need to be seriously vertically challenged to do any inspections!)
2) How much will it stop? Not a lot if the wind is blowing.
3) Snow on the gazebo will likely collapse it! Snow on a hive is often good, as it is a very good insulant (if it is quickly melted by the warmth from the colony, they are wasting too much energy!)
No, putting it inside a tent is a much better idea.......bees will be out to forage before the bulbs even sprout through the ground, if it catches the sunlight.
We are talking, of course, of 'cheapie contraptions'.
A more substantial construction may be a better idea. Especially as you don't say where you are in the UK. In Canada or parts of continental Europe, for instance, they are called bee houses (not to be mixed up with the famous plastic beetainer!) or bee cellars.
Save your money or invest some of it in some simple hive insulation.
