Hello everyone
The topic of "glass patio roofing" has already been discussed several times in this forum. It has become clear that such a glass roof only works well in summer with external awnings/shutters; otherwise, it gets unbearably hot. So far, so good.
Now, to all owners of such glass roofs with external shutters: how comfortable is it actually to sit under the glass roof with the shutters down during the (peak) summer? Is there really no heat buildup? Or does it still become unbearable under the glass despite the external shutters?
Our architect is currently strongly advising against a glass roof because it seems that—even with external shading—it is hardly bearable underneath during summer. He recommends a gravel roof instead.
For me, however, the advantages of a glass patio roof with sun protection shutters are obvious:
What do you think? Many thanks for your experiences.
PS: As an alternative, for example, a louvered roof could be installed for shading. This is said to be waterproof, and in peak summer the louvers can be easily adjusted horizontally to let warm air escape at the top, preventing heat buildup underneath. Does anyone have experience with this? I would be very grateful for any input.
Best regards

For me, however, the advantages of a glass patio roof with sun protection shutters are obvious:
- No darkening of the living room due to fixed shading (wood/gravel roof), especially in winter.
- Extremely flexible: without lowered shutters, it is still comfortable to sit underneath on colder (sunny) days (which is hardly possible with a wood or gravel roof because it simply gets too cold without direct sunlight).
What do you think? Many thanks for your experiences.

Have you ever looked at a louvered roof like that? It might be practical. The aesthetics are debatable, though. Also, it will darken the space since, proportionally, there are quite a few opaque edges around the glass louvers when viewing the entire roof area.
We had similar considerations in the same situation as you (a roof cover with as little darkening as possible for the living room). Since we couldn’t quite decide and didn’t want to spend money on something that would regularly cause frustration, we put the topic on hold for now. So I can’t share any firsthand experience.
In our residential area, they have now been installing roof covers with twin-wall polycarbonate sheets one after another. However, I’m still not fully comfortable with that option either.

Thank you for the response.
Sorry, I may not have been completely clear: by the "louvered roof" version, I mean a louvered roof made of, for example, aluminum, not glass. When fully closed at 100%, it would be like a solid roof (for example, a concrete roof), so completely darkened.
Of course, a glass louvered roof lets in much less light due to the framing, and on top of that, it is probably hardly affordable.

Of course, a slatted glass roof lets a lot of light get lost through the framing, and on top of that, it’s hardly affordable. I’ve seen this at a trade show and in an exhibition. We didn’t even ask about the price, as it was out of the question for us. Though aluminum and glass patio roofs aren’t exactly cheap either.
For us, there is the additional factor that we would actually need an awning at the front, since in the evening the western sun is too low for roof shading.
I would definitely advise against opaque roofing that connects directly to the house (it might be somewhat different if you have large windows on three sides). Why not consider a pavilion a few meters away? Alternatively, a fully enclosed conservatory.
Our own small 1.3 m (4.3 feet) canopy over the entrance area is already borderline. Two acquaintances experienced a terrace roof that resulted in a very cave-like atmosphere.

This is exactly why we do not want a solid roof, such as concrete, which would block all the light in the living room. However, we do want the seating area to be directly adjacent to the house, allowing direct access from the living room to the seating area. A glass roof would be ideal here, as it lets in light and can be combined with a retractable awning that hardly reduces the light. Still, I have concerns that even with an external sunshade awning, the terrace might become like a sauna during the height of summer. Therefore, I would appreciate any experiences or advice on this matter.
