The location of the skylight, or its type of opening or its dark curtain, for example, will thus be taken into account.

And even if you are a DIY ace, climbing on roofs is very dangerous. It only takes a few seconds of inattention for the unthinkable to happen. Instead, call on a professional, even more so if it involves the creation of new openings.

Note also that for the room to be livable and comfortable, the new skylights must be well insulated.
Before incurring the expense, check with your town hall, because a declaration of work is often mandatory for the replacement or installation of a skylight. And for people who live in co-ownership, obtaining the agreement of the other owners is also essential from the moment the modifications change the exterior appearance of the building. And this, even if the skylight is in the private part and not in the common area.
In addition, in the event of joint ownership, it is also important to have the approval of its neighbors since a minimum distance of 1.90 meters for oblique views must be observed and 0.60 meters for direct views. To conclude, the windows must comply with European Community standards.
