Awnings - the ones that bolt onto the house

I had one fitted last year. I think it would depend on the sophistication (and cost) of what you get.

The larger it is the more potential problem you will have. But there is another potential problem - rain. If you leave the awning extended during rain then it is likely to fill with water. Light rain will run off but more than that won't. Note: The recommended pitch is 14 degrees and then the water runs off better. Our pitch is less than that.

Your wall shouldn't be stressed by the wind affecting the awning but the awning might. There won't be any problem if you always retract it when leaving your house as, when you're at home, you can retract it if the wind is too strong. They can take a surprising amount of wind pressure.

The one we have is an electric one and is extended and retracted by a remote control. The awning also has an anemometer foxed to it which will retract the awning if the wind is too strong. The anemometer sensitivity is adjustable.

On a practical point - if it gets wet and you retract it, you should then put it out when it is dry so that the fabric dries properly.

Ours has been excellent. It is above our lounge french doors, which face south, and on sunny days we put it out even when we aren't going to sit out there as it keeps the lounge cooler. Apart from giving us shade when we're sitting out we can continue to sit out there if it starts drizzling.

As we're in a bungalow we didn't have a wall to fix it to. So we had to have brackets made to lift it above the roof line. The brackets are pretty hefty as the awning is large.

It really came in handy when we had our Open Day. It was baking hot and the Flamenco dancers were able to dance in the shade.

 

Clueless, it shouldn't be a problem if there is a sufficient degree of fall, as the rain should run off - and if you're sitting out there and the canopy starts to fill with water you can just push it off with a broom, from underneath. The problem should only occur if you leave it extended when you're not out there.

We, deliberately, didn't have sufficient fall (only seven degrees) so we have to be more careful - but we still sit out when it rains and keep a broom handy.
