Hello, If the roof is sagging, it could be because the roof has settled lower than supporting walls, also putting support beams in a very old roof is a specialist roofing job, and you must make certain that this type of work is necessary, as you could end up doing more damage to your roof! depending on the tiles the only way to determine if you need new tiles is to remove a selection and look at the quality of the face side of them. You need a good roofer to advise you on this roof, and take what the surveyor says with a large shovel full of salt. Regards Sam
