awning annexe holding rainwater

[TonyAsh]

I have a Dorema awning complete with a tall anexe, the roof of this annexe is flat and when erected rain water collects in the roof as there is no slope for runoff. In heavy rain a large pool collects and on the first occasion the weight caused the annexe to collapse - luckily without damage to poles. I have tried all ways to prevent this without success, rainy weather is a stressful time as I know water will collect during the night or when we are away from the site.

I have seen an 'awning rain pole' advertised in the catalogue Amazing Outdoors which looks to be suitable for raising the centre of the annexe, giving it slope.

Has anyone else had this water problem with the flat roofed Dorema annexe? I wish now that I had gone for the shorter version which has a really good slope for water drain.

My Dorema tall annex did the same until I used bungee rubbers stretched across the frame.

I now have a German awning which did the same but I now use the Halfords webbing luggage straps across the poles.

Thanks for you reply, how did it fit? as you know it's a real pain to have all this water collect.

Tony,

we have had the same problem, we have now bought another center annexe roof pole - haven't tried it yet, we are hoping because of the shape fo the pole it will push the roof up more then the rain will run off it

I think that the major problem occurs when the awning is just a little too big and the ladders for pegging down are not stretched.

Next time I buy awning I will go for the smaller size option.

My vans awning length is given as 988cm and the Isabella awning option that I chose was 1000 to 1025cm, I should have had the 975cm option.

I now carry two 2" thick planks so I can run up on these to effectively increase the awning rail length, hence the rubbers are placed under tension, keeping the roof much tauter.

something wrong somewhere,youre tall annex roof should not be flat.the centre pole should arch the roof upwards thus any water should drain of it???????

Hi Klarky, yes there is a centre pole with a slight bend in it for sloping, but when in position there is still a slight droop in the canvas at the edge where the canvas runs over the frame horizontal pole. Once the rain starts the water runs backwards and causes this depression to pool, the weight of the water then causes this to droop even further and the rainwater will collect quite deeply. I have noticed other annexes and they do not sem to have this problem, my annexe is a Dorema and it really is a problem as described in my original posting, others too seem to have the same. Tony

Refer to Klarky's excellent photo above.

I used 4 bungees, 2 from the ridge pole to the left hand rafter and 2 to the right rafter.

You can work out the spacing, all you are trying to do is to prevent a puddle forming by not allowing the roof material to sag. ie. encourage the rain to run off before a pool forms.

Yes Klarky, that's the style, although latterly I have been using webbing luggage straps rather than bungees as they are flatter and tighter against the roof material.

Tony,I have the same problem with my Dorema president. Even though the roof slopes, it still collects water. It has been back to the factory to be modified, but it's still the same. We are now afraid to use it in wind or rain.

Hi ,

It must be a facet of Dorema's as we have a Madison (5 roof poles) and on two occasions I had to use ducktape between the poles in order to stop the material sagging and water collecting. I have bought a Hercules tensioner and that just gives you that bit of extra tension that is required to taughten the roof. It did the trick.

Cheers
