The lifespan of a metal roof is considerably longer than other roofing materials. But even the most well-maintained metal roofs will eventually need to be replaced. Knowing when to replace your metal roof can save you thousands of dollars in the long run, and help ensure you and your family will be safe and protected. So how do you know when it’s time to replace your metal roof?
Inspect for Damage and Corrosion
The first step to determining if you need to replace your metal roof is to inspect it for any signs of damage or corrosion. Look for any rust, dents or punctures in the metal. If your roof is still in good condition with only minor cosmetic damage, then a simple patch job may be all that’s needed. However, if the damage appears to be more extensive, or if the metal is showing signs of rust and corrosion, then it may be time to replace the entire roof.
Check the Age of the Roof
Metal roofs are designed to last a long time, but they also tend to age out even faster than other types of roofing materials. If your metal roof is more than two decades old, it may be time to start considering a replacement. Even if there’s no visible damage, the older the roof, the more likely it is to suffer from wear and tear over time.
Check the Fasteners and Seams
Another factor to consider when determining if a metal roof needs to be replaced is the condition of the fasteners and seams. If the fasteners and seams appear to be loose or damaged, then it may be time to replace the roof. Loose or damaged fasteners and seams can cause significant water damage to the structure below the roof, so it’s important to check these regularly and to make sure they are securely fastened.
Look for Signs of Leakage
One of the most common signs that a metal roof needs to be replaced is leaking. Look for any signs of water damage in the attic or on the walls or ceiling of your home. If you find any signs of leakage, then it’s definitely time to replace the roof. This type of damage can quickly turn into a much bigger problem, so it’s important to address the issue before it gets worse.
Check for Mold or Moss Growth
Another indication that you may need to replace your metal roof is when you notice signs of mold or moss growth on it. Mold and moss can quickly accumulate on metal roofs, since they tend to stay damp due to condensation. If left unchecked, mold or moss can cause serious damage to your roof over time.
Check for Extra Loads
If you’ve recently added an addition to your home or installed an outdoor heat pump, it’s important to check the load capacity of your metal roof. The additional weight of these additions may require you to replace the existing metal roof with a heavier gauge material in order to support the extra weight.
Average Lifespan of Metal Roofs
Metal roofs generally last between 20 and 50 years, depending on the type of metal used, the quality of the installation, and the environment the roof is exposed to. Knowing the approximate lifespan of your metal roof can help you determine when it may be time to replace it.
