Hi,
I am planning to build a wooden patio roof next year.
I hope you can help me with a few questions.

1. The roof will be made of double-wall polycarbonate panels in milky white. What thickness should the panels have?
2. I would like to install a retractable awning on a rail system for sun protection. Most people have their awnings installed above the patio roof. Wouldn't it be more effective if it were installed underneath? Especially when it starts to rain.
3. Do I need a building permit / planning permission for the patio roof? I am currently planning a width of about 8m (26 feet).
4. One side should provide wind protection. Is it better to build this side with masonry or wood? Since it is the exposed side, the wood would be heavily affected by the weather.

Many questions are waiting for answers. I hope you can help me.

I’m aiming for at least 35 sqm (375 sq ft). There needs to be enough space for many guests and, especially, several grills.
I can’t find anything about WPC here at all. I’ll probably start a separate thread for that.

Hello,

You will definitely need the permit! A friend of mine also had to get one for his self-built pavilion attached to the house. Typical Germany...

1. The thickness and material of the panels depend on what you want to achieve. Depending on your plans, you will need different panels.

2. In my opinion, this is a matter of interpretation and space.
Awning on top: when it rains, it is much less noisy than when rain hits the hollow chamber panels directly. However, the awning might get damaged more easily. I think it all comes down to what you think is right and how you want to set it up.

3. As far as I know, this depends on the state or region you live in. To be safe, I would check with the responsible authority. But I assume you will probably need one.

4. Yes, you are right. If it is the weather-facing side, the wood will require a lot of maintenance. A masonry wall is more expensive but is airtight (windproof) and less vulnerable. However, wood usually looks better in most cases.

I hope this helps you.

Hi,
we also had a covered area for which we needed a building permit / planning permission. The official at the local building authority had very limited flexibility regarding the execution.

We had to submit all sorts of documents (structural engineering) and after just 3 months, we received the permit. You also need to keep the required setback distances from neighboring properties. That was the first issue for us, but our neighbor agreed. Then we wanted folding glass walls, but they were not approved due to the small setback distance. It was a really long battle in our case! Now we have a glass roof with a retractable awning under the glass. I really like that. Even if it’s very windy or raining, the awning is unaffected. On the sides, we installed vertical awnings. Those are great when the sun is low.
