That depends on the severity of the leak and whether the problem can be fixed by adjusting the tent setup. For example, if the fly is positioned too close to the tent so that the fabric touches the screen or tent fabric, water can leak into the tent during a rainstorm. A simple repositioning of the fly to allow for more space between it and the tent can solve the leak problem. Also, sealing the seams before a trip using liquid seam sealer or seam tape can reduce or prevent problems. The tent’s age can be a factor, too. After several seasons, a tent can develop small holes at the seams. Ultraviolet light can damage nylon and even polyester fabrics, too.
