If installed correctly and well maintained, shade sails are designed to last for many years. We have several sails that have been up a decade and still look good! The lifespan of a shade sail can, however, vary with environment, climate, and negligence. A critical part of your sail’s longevity is keeping it tensioned properly. A loose sail left to whip around in the wind will wear quicker than one that is tight. If you notice the sail losing tension, tighten your hardware further until it returns to the tension it should have.
Additionally, do not leave it up in snow or abnormally high winds. Snow allowed to settle on a shade sail will stretch the fabric beyond the point where it can elastically recover when the snow load is removed. Removing your shade sail during these weather phenomena will increase its lifespan.
