Hi,
I have a slightly sloping (1/60) flat roof with a velux atrium. Where the roofing felt has been overlapped it traps water from moving across the slope and the window stops the water from flowing down the slope.
The resulting pooling of water then creates splashing and the water splashes up into the air vents along the brick and roof join. I now have a leak inside where the water is dripping down the vents.
The builder has put a lead 'curtain' from the roof surface up to the vent to stop splashing. This curtain is covering the vent just by the pooling water and covers about 30% of the entire vent. I thought this was okay as the ventilation will still be okay.
However, after the very heavy rain this week there is another leak on the same scale. The builder has suggested putting a lead curtain accross the whole vent now and i am worried this will cause more problems due to condensation from poor ventilation.
Should i take his advice?
I was thinking doing the curtain to stop the leak in the short term, and work on getting rid of the pooling water so it doesnt splash up.
I need to raise the level of the roof slightly so it flows across the slope until it moves from behind the roof light, it can then flow down the slope away into the gutter. How can i do this? I was thinking liquid rubber and sand to make a trowelable material into a slope?
Or can i cover the vents with anything to stop the water but keep the air flow?
I hope that makes sense. Any suggestions would be appreciated.
Thanks,
Bryce
