Hi there,
We moved into a new build a few months ago.
Almost straightaway we noticed that when it rains, the water from a large section of roof, streams over the top of the box dormer windows to the ground (right in front of the garage entrance doors).
It doesn’t seem right to us and we’re trying to get a response from the developer, but after at least a month we haven’t heard anything back.
To us, it seems like there’s not enough guttering to sufficiently take away the rainfall that collects on the roof above, as it’s quite a large area. There’s effectively just two short sections of guttering for each side of the roof which is large. The rest just flows over the dormer windows where the guttering isn’t.
As well as having rain water streaming in front of the dormer windows when it rains, this is causing the wall and door area below to get damp. We’re concerned that the water could affect the foundations in the long run too. Also, we want to make sure the dormer windows are ok so they don’t leak in the future.
Just wondering if anyone has any tips on how the roof should handle the rain fall and are we actually correct in thinking that most of the rain should be taken away by the guttering rather than pouring on to the ground and walls below?
One solution we have thought of is if an extra section of guttering was installed below the last roof tiles before the rain hits flat roof of the dormer windows. Would this be a good idea? This is the blue line on the second picture.
Does anyone have any tips about how to calculate if the gutters are adequate for the roof and rainfall?
Or if it meets the building regs / control?
Thanks
