You should also remember that while the roof is being fitted or fixed the conservatory (and perhaps even the adjacent rooms) will be out of bounds for most of the time, so to make sure labourers can get on with the job you should avoid the area as much as possible – and perhaps even stay over a friends for a night or two if you can. Once they’ve installed the new roof, however, your conservatory will be ready to use and fully prepared for any kind of gathering or personal activity – come rain or shine!
