Don't use canvas.
Use calico from Spotlight and lots of paint which seeps throught the calico to form a seal.

We did our roof with calico.
I wrote a story about the restoration of the van. Here is the section about the roof.

Calico on roof.
While in Albury at the end of August we also picked up several metres of calico and chose a slightly cloudy day to roll the calico roof on. We didn’t want it drying out too quickly. We had washed the sizing out of it in a hot wash and spent 2 hrs crawling round the floor ironing the wretched thing. Calico wrinkles terribly when washed. We then rolled it up around a large cardboard roll to keep it as flat as possible. If we folded it, there would be creases. So with two tall ladders and one of us on each side we put about a metre wide layer of undercoat and sealer on the roof and proceeded to unroll and stick the calico to the roof. Once we got the first two metres done, it became easier. We ducked inside the caravan occasionally when we got to a skylight. Given the size of it, we didn’t do too bad a job wrinkle wise and no joins. Another 2 or 3 layers of undercoat and sealer and then two top coats – tight as a drum and leak-proof. When we bought the stuff we hadn’t measure the distance so made a rough guess and added some for shrinkage and a bit for luck. I think we had 10 centimetres left at the end to cut off.
After the roof was finished, and the calico was trimmed, the caravan’s edges were lined with aluminium J-mound and the sail rail was added for the awning. The roof skylights were also added and covered with tinted Perspex.

We did our little Globe with Calico from Spotlight.
No pre washing. put undercoat on roof, rolled calico on, stapled one corner & pulled across, stapled other corner & pulled tight, then stapled all edges.
Liberally applied water with paint rollers.(yes water!) When dry,cut excess off, put 2- 3 layers of undercoat (I'm struggling to recall exactly) then 2-3 layers of top coat.
