How to make a slope for Pergola roof?

[michaelsync]

I have a Pargolas similiar to this. 

I want to put a roof on it. 

Do you recommand to use the flat roof https://www.bunnings.com.au/sunlite-10mm-twinwall-x-3-0m-clear-polycarbonate-roofing_p1010590 or this one https://www.bunnings.com.au/suntuf-trimdek-3m-solar-grey-polycarbonate-roofing-sheet_p1010785 or corrugated roof https://www.bunnings.com.au/suntuf-1800-x-660-x-16-beige-cooltop-corrugated-1800mm_p0037610 ? 

The top part of my parlago are flat. I need to make a slope for the roof. I am thinking to put the Batons https://www.bunnings.com.au/42-x-42mm-5-4m-baluster-handrail-h3-pink-pine-fj-primed-losp_p0052850?pr... but they are all same size. Do I need to sand them to get different height? 

Thanks.

Hello @asmithdigital 

Another option that has come to mind is to use timber itself cut at different levels to achieve that gentle slope you are after. It would be much easier to customize than steel. There are steel brackets available at the store, but I'm not sure if they come in sequential lengths and if the hole positions are in line with your proposed plan. I suggest visiting your local store and having a look at what's in stock.

Thanks Eric. That is a good idea and I agree would be easier to customise than steel, I did think of that but felt that some kind of bracket would be nicer to look at than bit of timber. I would need to think about how I could achieve this whilst also ensuring it looks good

Good Morning @asmithdigital 

I would use timber blocks to attach extra horizontal height to your roof, Tho as it is a large area I still have a cautious attitude to adding weight. Timber plus sheeting and factoring in wind is the equation I have in my head.

Screw the timber block to the side of your beams so it is taller then the beam, then screw the additional pieces to those blocks. No expensive brackets needed.

Thanks @Dave-1 I appreciate your advice. Ill look into that idea and will check in with a builder/carpenter if i can to confirm the weight and wind requirements.
