We want to cover and provide shading for the area in front of the roof extension of our house with a glass and metal structure. It will be an add-on roof construction with an electric blind for shading. The structure basically consists of just two posts, connected horizontally to each other and at the contact point on the roof. In total, we are talking about 10.5 m² (113 ft²) of roof glass with 10 mm (0.4 inches) thick glass. We have obtained two quotes and were taken aback by the prices. The total comes to €23,000–26,000, WITHOUT installation of the point foundations for the two supports and without electrician work. We had previously expected total costs to be about half that amount. Is this the well-known “corona supply chain tradesman shortage—I can pick my jobs” surcharge, or have material prices really exploded as the two providers tell us (glass has doubled since the start of the year, aluminum supposedly as well)?

It also seems a bit expensive to me, considering that the neighbor mentioned around 30,000 euros (about 32,000 dollars) for a conservatory and carport combined. It was built by a small company active in southern Germany. I don’t know the details, so this comparison might be mixing apples and oranges.
Would self-assembly be an option? On a tip from @TmMike_2, I know of a supplier that ships relatively affordable kits.

Hello WilderSueden, we had several awning installers on site. The problem is the support structure, which is not really able to bear loads (see picture). Attaching it to the fascia board is not structurally possible, and the height would then be only about 180 cm (5 ft 11 in) after extending 2 m (6 ft 6 in) — and I’m 2 m (6 ft 7 in) tall. One installer wanted us to remove the support structure so he could install his awning, while a third suggested attaching it to the house wall beneath the support structure (ouch). We don’t really feel confident building it ourselves, and since it has to be an on-roof solution, most kits are out of the question anyway. Or is there a suitable option? I could organize a few helpers who are more than just handy.
Are you looking just for better shading or also for weather protection? If it’s only shading, I would use a sun sail. @Nida35a can show a nice solution for that.
For weather protection, your overhang is really impractical. In that case, maybe vertical elements would be better?

WilderSueden14 Oct 2022 10:25Yes, a rooftop installation is definitely one of the key reasons why it is so expensive. Off the top of my head, I wouldn’t know of any kit for that either. For a kit, it would have to be supported at the gable board or from the rear with posts, similar to a carport or pavilion.

xMisterDx14 Oct 2022 10:27Is “just waiting 2 years” an option? Glass is currently extremely scarce; my neighbors have been waiting 4 months for windows. Aluminum is also more expensive than ever... both materials require a lot of energy to produce, and energy prices are currently insanely high.
Yes, waiting is certainly an option. We are having the garden and terraces redesigned early next year, so it would have been ideal to integrate the pier foundations into the construction work and complete everything in one go. However, the delivery times for the components are already 4-6 months (at both offers we have), so a perfect timing is probably not possible anyway. I don’t know how you feel, but given the overall situation, a roof covering is really a luxury problem, and one has to be grateful to even be able to consider it. However, at least for us, this does not lead to a fatalistic attitude of just closing our eyes and pushing through. At the prices being asked, anyone who has already completed the project can count themselves lucky. We just got our photovoltaic system up and running (12 months from accepted offer to commissioning) and see that we were actually lucky this time (quote from the installer: “You could weigh inverters in gold right now…”). Of course, projects can be killed by sitting them out, but in this case with the roof covering, waiting seems to be the only sensible option, or the umbrella solution (not comparable, I know…).
