Part 1: Why is My Metal Roof Leaking?
Metal roofs are said to last ages, and if that’s the case, it leaves most homeowners wondering why it is leaking in the first place. Metal roof leaks can have several different causes, but if you can identify them, you can prevent them, which is why we first break down the most common causes of metal roof leaks below:
Proper installation is the foundation of a leak-free metal roof. When metal roofs are poorly installed, they become susceptible to various issues. The most common mistakes are:
- Incorrectly placed screws
- Missing sealants or flashing
- Unsealed seams
If the installation process is flawed, it will leave your roof vulnerable, and metal roof leaks will inevitably show up.
Major Weather Events
While metal roofs are highly resistant to adverse weather conditions, extreme events like heavy rain, hailstorms, or snow can take a toll over time. Prolonged exposure to such elements can lead to damage, causing leaks to develop. Even the most robust metal roofs can eventually succumb to nature’s fury.
Capillary draw is a lesser-known phenomenon in which water is drawn upwards between overlapping metal panels due to surface tension. Over time, this can lead to leaks if not properly addressed.
Expansion & Contraction
Metal roofs suffer from thermal expansion and contraction with temperature changes. This natural movement can loosen fasteners or create stress points in the roof, potentially leading to metal roof leaks over time. Understanding how your metal roof responds to temperature changes is essential for proactive maintenance.
Flashings and sealants are critical components in preventing leaks. Over the years, these components can wear out or deteriorate, compromising the roof’s integrity. Regular inspection along with maintenance are essential to identify worn-out parts promptly.
