Are patio awnings waterproof?

Are patio awnings waterproof? The simple answer is yes….but be careful.

The reason I say be careful is that patio awnings are designed for sun protection. They will give you a valuable space in your garden without suffering from the effects of the sun. They will also keep your rooms cooler.

Are patio awnings waterproof? The fabrics

Most good quality awnings have fabrics with a teflon coating which works really well should your awning be out when it is raining.

Some of the less expensive awnings will absorb more water which is not ideal and could cause damage to your awning over time.

Are patio awnings waterproof? The installation

This part is really important if you want to be able to use your awning when it is raining.

Your awning needs to be fitted so the fabric is on a slope. The bigger the slope the better as the water runs off quicker.

A professionally installed awning will have a minimum slope of 300mm (12 inches) per metre of projection.

The front of your awning when all the way out will be 2 metres from the floor to allowing people to walk under without hitting their heads.

So if you wanted your awning to come out 2 metres from your home the awning will be fixing at a minimum height of 2.6 metres. 3 metre projection then fixing height would be 2.9 metres.

If your awning is installed with less of a slope than that your awning fabric could collect water because it can’t run off and if it is out long enough in the rain the weight of the water collecting in the cover could either snap the awning support arms or pull your awning off the wall.

More than 300mm slope per metre gives the water even better run off.

Are patio awnings waterproof? The framework.

Again fairly important. The more robust the awning framework the better for the reason listed above. An awning out in the rain will add extra weight to the fabric so the stronger the support arms  the better.

One of our awning suppliers has a gutter system built into the front rail so rather than the water running off in various places in only runs off in the corners.

An addition you can add to one of our awnings for better weather protection is a drop down valance.

Most awnings have a fixed valance at a set size of around 150mm.

The drop down valance is built into the rail and can be rolled up and down to the ideal position even all the way down to the floor.

A great option for sun protection but also works well when the weather is not so good.
