July 2, 2022

As a homeowner, you want to make the best decision possible when it comes to your roof. After all, your roof is your first line of defense against the elements, so you want to make sure it’s strong, sturdy, and Metal roof coating able to withstand whatever Mother Nature throws its way. But when it comes to metal roofs, how do you know if you should replace your roof or simply coat it with a protective layer? Here are some key points to consider when making your decision.


The first thing most homeowners consider when it comes to home improvements is cost. While replacing your metal roof may seem like the obvious solution to a worn-out or damaged roof, it can be quite costly, especially if you have a large roof or multiple steep slopes. In contrast, coating your metal roof is generally much less expensive than replacing it. Plus, a quality metal roof coating can go a long way in extending the life of your roof, adding an extra layer of protection against the elements.


When it comes to longevity, it’s important to consider both the lifespan of your metal roof and the lifespan of the coating or roof sealant you choose. A good quality metal roof should last 40-70 years, depending on the type of metal and the quality of the installation. However, even the best metal roofs can start to show signs of wear and tear after a decade or more. By coating your metal roof, you can extend its lifespan even further, providing an additional 10-15 years of added protection.


Another consideration when deciding between coating and replacing your metal roof is the level of maintenance required for each option. The good news is that both options require very little maintenance. However, if your metal roof is showing signs of rust or other damage, a coating may not be enough to repair the damage. In that case, you may need to have the damaged portions of the roof replaced.

Energy Efficiency

Metal roofs are already known for their energy efficiency, as they reflect sunlight and heat away from your home, keeping your home cooler in the summer and warmer in the winter.

This can help you save on your energy bills, while also keeping your home more comfortable year-round.

Environmental Impact

Finally, you may want to consider the environmental impact of both options when deciding whether to replace or coat your metal roof. Replacing a metal roof can generate a significant amount of waste, which can have a negative impact on the environment. In contrast, coating your metal roof involves very little waste and can even help reduce energy usage and greenhouse gas emissions, making it a more environmentally-friendly option.

In conclusion, whether to replace or coat your metal roof ultimately comes down to your individual circumstances and priorities. While replacement may be necessary in some cases, coating your metal roof is typically a viable option that can save you money, extend the life of your roof, and enhance its energy efficiency. Whatever option you choose, be sure to work with a reputable roofing contractor who can provide expert guidance and quality workmanship to ensure your metal roof is strong, sturdy, and able to withstand the test of time.
