One skylight vs. two skylights, price difference?

Horrido,

we are planning an open saddle roof structure with a 25° roof pitch. The bathroom should be located roughly in the middle and under the ridge at one point. Since the bathroom, with a width of 3.5 meters centered under the ridge, does not allow for particularly large roof windows on both roof sides, we are now considering a ridge window. Although you can occasionally find absolute prices for the bare window, for example at Velux, I am currently missing information about the possibly higher installation effort compared to two roof windows with the same window area. At the moment, I cannot assess how much more complex a ridge window is than a roof window between the rafters.

Can someone help me with experience in this?

I think someone would first have to be able to imagine what you are planning. You have been here long enough to know the value of the illustrations.

Horrido, we are planning an open gable roof with a 25° roof pitch. Fairly centrally and under the ridge, there should be a bathroom in one spot. Since the bathroom, with a width of 3.5 meters centered under the ridge, does not allow for particularly large roof windows on both roof sides, we are now considering a ridge window. Although you can occasionally find absolute prices for the bare window, for example from Velux, I currently lack information on the possibly higher installation effort compared to two roof windows with the same window area. At the moment, I cannot estimate how much more complex a window in the ridge is compared to a roof window between the rafters. Can someone help me with experience?

I am just wondering what happens with the ridge beam with such a window? At 25° pitch, shouldn’t two roof windows about 1.2 x 1.4m in size each be possible?

It might look something like this. The question is whether this works with completely normal roof windows? I lack the knowledge regarding distances to the ridge. Or am I inventing a problem? A 1-meter-high window should be possible, depending on how far you have to stay away from the ridge beam.

When googling for ridge windows, I come across something like this, but this seems to be something different again:

Addendum... just checked with Roto. One of the standard sizes is 78 or 98 cm in height. That would be quite feasible, I think. Nevertheless, out of interest, does anyone know how much more a ridge window or over-ridge window, as I have now learned, costs compared to regular roof windows?

As in the third (lower) picture, it is easiest, in the second (upper) picture it will be more difficult (to me they look wider than one rafter field per element). Unfortunately, you forgot the first picture (how we have to imagine the situation with you), but that would be the most important.

Still, out of interest, does anyone know what a ridge window or ridge-over window, as I’ve learned in the meantime, costs compared to normal roof windows?

Ridge-over window, aha, you always learn something (?)
The ones in the lower picture are comparatively cheaper; they don’t look tiltable to me (but probably include sun protection).
