Still Spinning… But Still a Problem

From my experience maintaining homes, I've seen many cases where roof turbines continue to spin after hail damage but don't function correctly. It’s easy to assume everything is fine since the turbines move, but damage to their surfaces can reduce airflow efficiency significantly. This subtle issue often goes unnoticed until homeowners start experiencing issues like increased attic heat or moisture, which can harm insulation and roofing materials. In one case, a neighbour delayed checking their hail-damaged turbines because they ‘still worked.’ However, within months, their roof decking showed signs of rot from trapped moisture, leading to costly repairs. The key takeaway is to schedule thorough inspections post-hail storms, focusing not just on visible breaks but on operational efficiency. Some technicians use airflow tests to verify performance. Additionally, ensuring proper roof ventilation supports energy efficiency, prevents ice dams in winter, and prolongs roof lifespan. Replacing or repairing damaged turbines promptly can save money and headaches in the long run. For homeowners, understanding that functional wear may not always appear broken visually is crucial for proactive roof maintenance.
