Hello everyone,
Since this is about being "outside," this seemed like the most appropriate subforum.
We have been living in the house for 3.5 years now and are currently looking into the topic of patio roofing. I have already had initial on-site discussions with two local companies. Unfortunately, these talks raised more questions than answers.
The area to be covered is about 26 sqm (280 sq ft). Width 7.30 m (24 ft) and depth 4.00 m (13 ft), with the special feature that part of the patio narrows diagonally, so the depth on the left side is not 4.00 m but 2.00 m (7 ft). This means that part of the roof and drainage must slope diagonally and be adjusted on-site; a roof of a standard size x by y meters won’t work for us.
What we originally wanted and were offered:
- Powder-coated aluminum construction
- 10 mm (0.4 inch) laminated safety glass (VSG) roofing
- LED spots integrated into the rafters
- Under-roof shading with a wireless sensor
- Both sides (left with 2.00 m (7 ft) depth and right with 4.00 m (13 ft) depth) closable with frameless glass sliding doors
This option costs 19,000 EUR. Shading on top of the roof with a weather station was even more expensive. Shading adapted to the sloping area was even pricier. The affordable under-roof shading would not cover the sloped section of about 3 sqm (32 sq ft).
What the second company proposed:
- Powder-coated aluminum construction
- White milky polycarbonate twin-wall panels roofing *
- LED spots integrated into the rafters
- No shading
- Only one side (right 4.00 m (13 ft) depth) closable with frameless glass sliding doors
This option costs "only" 8,000 EUR.
* This company specializes in polycarbonate twin-wall panels. Apparently, this roofing has many advantages. A double UV filter protects against the sun, while an integrated prism structure is said to concentrate sunlight and direct it downward, resulting in only 7% light loss. Supposedly, no shading is needed. The climate under it should always feel as if you are sitting in the shade. Polycarbonate is said to be self-cleaning.
I am mainly skeptical now. Of course, I would prefer the cheaper option, but I find it hard to fully believe all these benefits, especially the claim that no shading is necessary. Do you have any experience with this? The main argument against twin-wall panels seems to be noise during rain, but that doesn’t matter to us, so that argument is irrelevant.
Overall, it is very difficult to find a suitable company and to assess the prices. How did you solve this?
Thanks and best regards!

So, three supports are planned at the front: one on the left side (with a depth of 2 meters (6.5 feet)), one on the right side (with a depth of 4 meters (13 feet)), and one at the point where the terrace begins to slope diagonally from 4 meters (13 feet) depth to 2 meters (6.5 feet) depth. Foundations are included, as well as installation on the ETICS (external thermal insulation composite system). The plan is to drill at the floor slab level and glue threaded rods in place. The shading system would specifically be a Warema W10 under-roof model, consisting of two parts with two motors and two remote controls. Additionally, there would be 13 LED spotlights included.
I need to take care of cutting out the terrace slabs (notching for the posts) and reinstalling the three terrace slabs that will be removed at the post locations. I currently don’t have the exact dimensions of the posts.
§ 62 Exempted construction projects, removal of structures
g) Terrace roofs with an area up to 30 m² (323 sq ft) and a depth up to 4.5 m (14.8 feet), balcony glazing as well as balcony roofs up to 30 m² (323 sq ft) floor area, conservatories up to 30 m² (323 sq ft) gross floor area on buildings of building classes 1 to 3 with a minimum distance of 3 m (9.8 feet) to the neighboring boundary.
There was apparently a change in 2018 or 2019 that now offers more flexibility. Our terrasse has a depth of 4 meters (13 feet), an area of 26.2 m² (282 sq ft), and maintains the 3-meter (9.8 feet) boundary distance on both sides, so the roofing is exempt from requiring a building permit / planning permission.
We will submit a design change. We now believe it makes no sense to enclose the left side with the 2-meter (6.5 feet) depth. We want to remove this part. As a result, a floor-level adjustment beam, a three-part sliding glass wall, and a glass wedge would no longer be needed. I’m curious to see how this will affect the price.

§ 62 Exempt Building Projects, Removal of Installations
g) Patio covers with an area of up to 30 m² (320 square feet) and a depth of up to 4.50 m (15 feet), balcony glazing as well as balcony covers with a floor area of up to 30 m² (320 square feet), and conservatories with a gross floor area of up to 30 m² (320 square feet) on buildings of building classes 1 to 3, with a minimum distance of 3 m (10 feet) from the neighboring boundary I had previously linked the Building Code NRW without permission. Well, I’ll accept that, but at least I want to restore the context here.
We have now placed an order for a canopy. The work will start around mid to late March. The side sliding wall will be made with panes set into profiles after all, to ensure a tight seal. There will be 13 LED spots. Wireless remote controls for both awnings. Square posts, but a rounded gutter cover, as we want a more robust appearance.
