leaking tiled roof terrace
We just bought a house that has a tiled terrace on part of the garage and covering a lower level mudroom. Some of the tiles are cracked and the grout has deteriorated in some areas. I plan to re-tile the terrace when the weather warms up a little bit but wanted to find out what is the proper water proofing methods for such an area. I don't know what's under the tiles, but whatever it is, there must be some damage since it is leaking through in some areas. I have heard you can lay plastic or hot mop, but I want to use the most durable and longest lasting material/method to prevent future leaks. Any suggestions would be appreciated. I can post a photo of the terrace if it would be helpful. :confused:

Roman, 1st off welcome to House Repair Talk. Next, if you can, post a pic of the area you are talking about.

Sounds like your going to have a big mess on your hands.
Sounds like some DIY job to me. If this is a flat roof there should have been a one piece membrane layed then a platform could have been built for a deck that just rest on top of with reguler decking boards but never tile.
Hot mopping can be done but not until all the old roof gets taken off and a whole new underlayment layed and any needed repairs to the old roof rafters.

I posted some photos but the message is waiting for moderator approval, probably since I am new here. I appreciate your input, maybe you can chime in once you see the photos. I hope it does not get that complicated.

Here are some photos of the project in question:

Roman, what area of the deck is leaking? And where does the water drain to?

In the first photo in the second set, sorry for duplicates, I didn't think the first set went through, where the t1-11 is painted brown and fern hanging above, there is a gap on the bottom and behind it there is an area that has a gutter around it. There is no drainage anywhere else on the deck. In the second picture, where you can see the garage roof, water sits there in some spots. Before we bought the house, they did repairs on the railing and put new t1-11 where it is primed. I believe this was due to rotted wood. In the corners where the tiles/grout meets the wood, there are thin gaps, so water could be coming in that way. I'm not sure why they would fix all the railings and leave the tiles as they are. So there is a problem with drainage due to the leveling of the deck. I was thinking of at least re-grouting the tiles, replacing the cracked ones, putting in some kind of sealant in the corners where it meets the wood and hopefully this would water proof for the time being. Again, I'm not sure what is under the tile.

Roman, how would you feel about getting an awning company to put a cover over the deck area? It will be a lot cheaper and a lot less invasive than a proper fix.
