I need to do something about my roof (large number of broken tiles, all are deglazed and the pointing is crumbling). It is not actually leaking but it is not good.
Does anyone have any experience with roof restorations on concrete tiles. The general process is to replace cracked tiles, re-bed and re-point ridge capping, high pressure clean whole roof and then apply a proprietry coating (basically a special paint applied by sprayer). Various warranties and longevities are claimed by the companies involved.
I was not impressed with the sales tactics of the well known roof restoration company that inspected and quoted (they won't actually leave you with a written quote and want you to sign a contract on the spot) I have also heard mixed results about how long such a coating lasts.
