Hi folks
I recently got my attic converted and got some Optilight roof windows installed onto the existing tiled roof. I am currently at the snagging phase with 25% of the bill left to be paid. I have two queries:
- I have noticed that if the windows are marginally opened on a wet day that the horizontal channel at the bottom of the windows (see photo with channel highlighted in red) quickly fills with water and it then starts spilling over and down the wall. When I then fully close the window, water continues to seep down the walls for a period of time and eventually stops when the water level in the channel has presumably dropped to a low level. I would have expected that I could avoid the rain getting in if the windows are only slightly opened, and would also expect zero water to get in after the windows have been closed - is this wishful thinking?
- See attached some other pics of the roof tiles. As you can see some of them are positioned at a slightly different angle to majority of the tiles, and as a result there is a noticeable gap under some of the tiles. The independent engineer has requested that the gaps are filled to avoid potential water egress and also avoid potential bird nesting. The builder claims that his work is standard and that the window manufacturer would not replace the window (if required in the future) if the tiles surrounding the window are permanently sealed up. Who is in the right here?
