Do You Really Want a Fully Waterproof Shade Sail?
We are a shade sail specialist dedicated to protecting people from harmful UV rays while keeping outdoor spaces cool, comfortable, and enjoyable on sunny days.
When customers ask, “Do you have waterproof shade sails?”, our first thought is often:
do you really need one? (It might be more like wanting an umbrella!)
We specialise in high-quality, breathable (mesh) shade sails that are highly showerproof. We do not manufacture fully waterproof shade sails ourselves — and we’ll explain why we believe breathable sails are usually the better choice for most situations. However, we now have an established partnership with
SD Sails (based in the UK), experts in properly engineered waterproof tensile canopies. If you are set on a fully waterproof solution, we will happily redirect you to them.
Nearly Waterproof (Showerproof) Shade Sails – Our Recommendation.
Our sails are highly showerproof. In proper rain (with at least 20–25% slope on the sail), water sheets across the top surface and runs off to the lowest point, with only a minimal line of drips underneath in heavier downpours.
Rain rarely falls perfectly vertically, and shade sails are installed well above head height. In most real-world scenarios, if you’re standing toward the centre of one of our breathable sails, your head and shoulders will stay dry — without the drawbacks of a fully waterproof fabric.
Breathable mesh also allows hot air to escape, preventing the greenhouse effect that can build up under solid waterproof materials on warm days.
Totally Waterproof Shade Sails!
This image shows a car parked beneath a fully waterproof shade sail after rain. The car is dry, along with a small dry area nearby — but you can clearly see well over 100 litres of water ponding (sagging and pooling) in the centre of the sail, just waiting for a gust of wind (or someone brushing against a post) to dump it all at once.
Poorly designed or insufficiently tensioned waterproof sails are particularly prone to ponding, which adds weight, stresses the fabric and fixings, and can lead to sudden large water dumps.
Heavy rain is usually accompanied by wind and a temperature drop, making prolonged outdoor time uncomfortable anyway. In many cases, the need for complete waterproofing becomes less critical.
That said — fully waterproof shade sails
can perform extremely well
when designed and installed correctly. Proper engineering with adequate slope, high tension, and the right structural support allows rainwater to shed cleanly without ponding.
This requires specialist expertise, which is why we have partnered with
SD Sails — the UK’s leading specialists in high-quality waterproof tensile canopies and shade sails.
SD Sails use premium waterproof fabrics combined with advanced 3D design and professional installation to ensure excellent water run-off and long-term performance. They offer a full end-to-end service design, manufacture, and installation.
If you definitely need a fully waterproof solution that is engineered to handle UK weather reliably, we strongly recommend contacting
