Hi Sifus,
My extended kitchen area has leaks at the corner. My next door neighbour did not extend hence the opposite wall is open area. My roof is a slanted with tile roof. It will start to show wet water marks just with moderate rain. Backed in March before I moved in the contractor has applied some sealant on the roof when I complained on leaks. it seemed the problem is still there. Any recommendation to fox this ?
