The answer to 'my emergency roof repair is failing' is that there are several common causes, including poor workmanship, improper materials, or damage from weather conditions. Symptoms may include leaks, sagging, or visible deterioration of the repair. To address this, you'll need to carefully inspect the repair and determine the root cause.
If the emergency repair was done hastily or by an inexperienced contractor, it's likely that the work was not done properly. This can lead to the repair failing prematurely. Using the wrong materials or techniques can also cause the repair to break down over time. Severe weather like heavy rain, wind, or hail can also damage a temporary roof repair, leading to further issues.
