Do you leave loftroom Velux open at night in your mid-terrace home?

Just that really.

If you have a loft conversion with Velux windows in your mid-terrace home - do you leave the Velux open at night?

Would it make a difference to your answer depending on who occupies the room or the room's purpose?

Why? I keep saying this and nobody has expla8ned. My veluxes (25 years of use) have never let rain in. Are yours open to horizontal? I can see that might be a hazard. Open a little bit - like up to quarter of the way? Never been an issue. 3 different veluxes, 2 different houses.

If the rain falls completely downwards, none comes in. But if the rain is slightly at an angle, it can easily come in at the side - this is open about 25-30cm so not an unusual amount. Basically if there’s any wind / breeze. Maybe your windows are at a steeper angle? Maybe prevailing winds never come from that direction? We’ve had wet areas under the window most time it rains, if we’ve forgotten to close it.

I used to until I was woken up by a squirrel in the room.

I don’t really know how to explain it other than it came in through the gap, regardless of how open the window was. Obviously more came in if they were really wide open. My bed was right underneath and I was frequently woken up by rain.

How strange. Not my experience.

Your roof looks a shallower slope than either of mine. Wonder if that makes a difference. Also I think in both cases the roof stood a bit proud of the window so maybe baffled the rain?

I worry about crows getting in so always close it.

I read that as cows and had been sent off on a mild diversion....

thehorsesareallidiots · 30/04/2025 14:20

We get rain in if we leave the veluxes wide open enough. Not to a flood level but to a damp patch on the floor level certainly. I would close them or leave them just cracked if I was going out and rain was forecast.

wonkylegs · 30/04/2025 14:47

Unless there is scaffolding or an easy route to climb up onto the terrace roof it’s not realistically an issue to have your Velux open. Even if it’s not open, you can actually pop them open from the outside if determined enough
I’ve seen a builder do it (it was the easiest way to get access to fix something)
The main reason they are not usually a target for opportunist burglars is it’s to much of a faff to a get up there and then climb in especially as it’s very visible once your up there and you don’t know what you’ll find inside so there are easier ways to burgle

Yes, that seems likely.

Only if it’s occupied so you wake up if it’s raining as your room will get soaked if the velux is left open

I am the voice of experience… I once owned a very soggy carpet when the weather changed and
someone forgot to shut the velux…

ghostyslovesheets · 30/04/2025 15:40

I leave my bedroom window open 24/7 even when I’m away overnight as the cats use it as a cat flap

front of house, not massively accessible without a big ladder, ring doorbells on all the neighbours houses and nowt really worth robbing!

mondaytosunday · 30/04/2025 16:30

I leave my first floor bedroom window open. The study window is open, and my back bathroom window is open almost permanently (though this may not be wise as there’s an extension underneath so I guess a nimble person could access it).
My DD has the converted loft and yes she has the windows open when she’s here (she’s at uni now).
If we were away all windows shut and locked obviously.

mindutopia · 30/04/2025 16:32

I personally probably wouldn’t because I assume if you are mid terrace there are neighbours either side to create a lot of noise and you are in a town or village, so again noise. I wouldn’t not leave them open because I thought someone might climb in or out.

SeventeenClovesOfGarlic · 30/04/2025 16:38

I did and a bat came in.

mackawhack · 30/04/2025 16:39

I would leave it open a bit like my bedroom windows. Even in London I think it's unlikely that burglars try & get in through the roof!

mackawhack · 30/04/2025 16:42

Our back bedrooms could be accessed by climbing on the kitchen extension which is much easier so I don't open the big ones. But the little ones wouldn't fit a body through. I do find it odd when some people have just huge windows and no little windows.

Glittertwins · 30/04/2025 17:02

We’ll shut them if rain is forecast . They’ll stay open tonight just as they have been the last few nights it has been warmer.

outlanderish · 30/04/2025 17:05

Always open! Good luck to anyone getting to our townhouse roof lol!

WillItEverWork · 30/04/2025 17:11

We leave ours open, I try to limit though not because of burglars etc, but because how much light they let in as soon as the sun rises.

re insurance we was burgled, after we accidentally left the front door unlocked over night, had pay outs from both the car and home insurance.

Edited

Here’s one I can’t quite grasp - does the room not get very bright at about 5am (or earlier as summer goes on) if you have the velux windows open overnight? We have blackout blinds on ours to keep it dark, and if we open them, the light comes streaming in early. So we open the other windows behind the curtains.

Probably it makes a difference for us as the velux face due east. Or do people have some sort of way of shielding the light while opening the velux?

Most burglaries are via the doors, it would be an exceptionally acrobatic thief who could get onto a roof

Even with scaffold up further along the terrace? I'd hardly say that's acrobatic.

I did once watch a burglar getaccess to a terraced house via the loft velux. I was at work, we phoned the police and they were straight round to apprehend him.

Detered me from.leaving my velux open when we lived in a terrace.

HelenHywater · 30/04/2025 17:13

Yes left open as kids are in the bedrooms up there and the rooms get too warm in the summer.

We also had a flooding incident after a torrential rainfall (in August) - rain made it through floors/ceilings two levels down.

Usually there isn’t scaffolding up though? I probably wouldn’t leave them open and unattended if there was scaffolding a door or so down / builders climbing about all over the roof elsewhere. But that’s not happened down our road (apart from us getting ours done).

Unlikely, but not impossible or completely improbable.
