My clay roof has been leaking since we built this house 5 years ago. So much so that the ceiling is now rotting and falling down in chunks, both the drywall and the plywood in between the drywall and clay. The joining between the split level also leaks down the wall whenever it is hot and it had been raining prior. The builders tried to fix it several times in the first 2 years, trying different sealants on the wall and roof, and trying layers of cement over the flashing at the wall, but couldn't solve the problem. Is this a clay roof in the picture here? Does clay have a lot of pores? How can they prevent it from leaking? Ideas for split level wall? I live in Belize and don't have access to professional roofers experienced in clay. One roofer said to coat with tar, another to use expandable cement good in rain, another to replace with zinc... Please help if you can. Thank you
