On he side a skylight was added last year and even after numerous attempts to seal it the contractor has failed to sop the leaks. Depending on the wind direction and the volume of water the other side still leaks occasionally also. That side now has a deck over it now, which will need to be lifted.

IRB waterproofing quote needed. Greetings to whom it may concern, I have a house with part of the roof being flat. The problem initially was the gutter connectors are to small for a large amount of water. Subsequently outlet avenues were made available as to alleviate the water buildup. I have had work done on the roof and recently had an assessor from outsurence asses the roof His recommendation is that a thorough waterproofing needs to be done as the waterproofing done last year is flaking and allowing some water to seep through. This needs to be sorted out and would request an assessment and quote in this regards.

I have an open balcony on top of a concrete slab. Under the balcony is my scullery as well as a bedroom. Between the tiled floor and the wall around the balcony, water is leaking into the scullery and bedroom. The leaks are only just where the roof and the wall meets, not any other places on the roof. In the corner of the bedroom you can also see the damp on the wall, just opposite the one outlet of the water on the balcony.
