ᐅ Patio Roof – What Is the Cost of Twin-Wall Polycarbonate Sheets?

Hello,
We want to cover our terrace.
The terrace is 20sqm (5x4) in size, and we would like a roof with twin-wall polycarbonate panels that let sunlight through and do not get algae growth too quickly. The structure should be made of laminated timber.
Does anyone perhaps know roughly how much such a project would cost if done by a company? 😕
Or could it also be done as a DIY project? We have plenty of tradespeople in the family.

Hello

The material costs should be around 1000 euros.

Then you hire a skilled carpenter for one Saturday.

So about 1250 euros in total.
