Tiled terrace on garage roof leaking rain in to garage
Hi,
I have a concrete block built garage the roof of which acts as a terrace/patio. It is tiled with quarry tiles. Recently, during severe weather, the rain has started to run through the tiles (somehow? The grouting was waterproof and looks OK) and through the joints in the concrete into the garage.
Is there any way to: waterproof over the tiles? Or waterproof the garage ceiling?
I have an awful feeling that the only way will be to take up & re-tile with membrane (or use lots of buckets on the garage floor)
Thanks in anticipation
Pat
