Construction costs are currently skyrocketing

Something new again about the current prices for a renovation

Roof renovation approx. 120 sqm floor area and 155 sqm roof area:
With insulation of the top floor ceiling approx. 56k
With counter-rafter insulation approx. 61k
Both offers complete with plumbing work, scaffolding, new folding stairs and with Brass

For comparison. New build, passive house. Roof areas 180 sqm, with 160mm above-roof insulation WLG024. Creaton tiles. Including all other preparatory work and drainage. €42,000 gross. Plus another €6,000 for the insulation between rafters, which is supplied and installed by the carpenter. Scaffolding excluded, as contracted separately. But it is also used by other trades

Even if 4 roofer journeymen re-roof the roof in 1 week, I come to 200 working hours. These are no longer serious offers at all. Of course, the company wants and has to cover its costs and make a profit. Then they probably charge 100 euros per hour for a student assistant. Usually, 20 percent was calculated for profit and risk in the past. Today it is more like 200 percent.

Since you unfortunately only listed half of the necessary materials, the entire calculation doesn’t fit. Aside from that, if you look into the financial statements of construction companies/tradesmen (I don’t know the small one-man businesses, only the larger ones), you can sit for weeks beforehand and look for the 200% profit. You simply won’t find it. But yes, it is more than 20%.

Well, I am a craftsman master myself and have practically learned how to calculate an hourly billing rate from the ground up.

How you arrive at a billing rate of 120 euros for an unskilled worker, who perhaps earns 18 euros gross at best, is a mystery to me. Certainly a bit exaggerated but basically often the reality again.

As long as the customers pay, there is said to be a fool standing every day (you just have to find him), as long as that is the case, everything is fine.
Let's see how much longer.

The day before yesterday I ordered [Silikat außenputz]. Ready mixed and 3mm grain size. The price per kilo has risen from 1.58 in 2020 to 2.05 today. So that's still somewhat reasonable. Now the 25 kilo bucket costs 11.75 euros more.

For comparison. New building, passive house. Roof areas 180 sqm, with 160mm insulation on the roof with WLG024. Creaton tiles. Including all other preliminary work and drainage. €42,000 gross. Plus another €6,000 for the insulation between the rafters, which is supplied and installed by the carpenter. Scaffolding excluded, as it is awarded separately. But it is also used by other trades

Would that even include the roof truss, since it is a new build? In my case, the old roof truss remains.

How one arrives at a billing rate of 120 euros for an assistant who maybe earns 18 euros gross at best is a mystery to me. Certainly somewhat exaggerated but basically often the reality again.

Calculation roughly rounded: Gross wage €20 Ancillary wage costs €16.5 Overhead costs €24.5 Profit €3.5 ==> Hourly billing rate €64.5 VAT €12.25 ==> Hourly billing rate end customer €76.75 Yes, you have exaggerated. But that is roughly the calculation for a journeyman's working hour. Everything between €60 and €85 is reasonably calculated. One-man businesses calculate somewhat differently.

Something new again about the current prices for a renovation

Roof renovation approx. 120 sqm base area and 155 sqm roof area:
With insulation of the top floor ceiling approx. 56k
With rafter-over insulation approx. 61k
Both offers complete with sheet metal work, scaffolding, new folding ladder and with Brass Tumalin tiles

Replacement of approx. 13 windows, brand Guggelfuss, including one balcony door, 1 large one approx. 3m wide and 5 basement windows including aluminum roller shutters, exterior boxes, fly screens and motor approx. 31k. Roller shutters everywhere except on 3 basement windows
Front door two-tone Schüco, aluminum with large glass surface 5.3k
Front door two-tone Schüco with large glass side panel (1.60m), also aluminum, just under 9.5k
All triple-glazed

Hi, since I read Gugelfuss here, I guess we are from the same region :)
We also have windows and blinds from Gugelfuss. I found it disappointing that the installation was carried out by subcontractors, which was never mentioned. Defect repair was a disaster. Only when I reduced the final invoice did I get to the boss, who then coordinated all the defect repairs himself. We thought we were dealing with a premium provider here but were disappointed in terms of service. However, windows and blinds are good.
Regarding roof renovation: In 2018, Holzbau Graf and Oberlander were very attractive in terms of price. Both are in the Dillingen area but would not have had a problem driving to the Ulm region at that time... We had one of the two and were very satisfied. I would also get quotes there.
For our new build roof (around 140 sqm roof area + 2 dormers): roof structure + Steico external roof insulation (but only about 10 cm) + sheet metal work + Creaton engobed tiles, we paid €25,000 in 2018-2019.
