Metal roofs are long-lasting, but they do not last forever. For this reason, it is important to learn about the indicators of a deteriorated steel roof. After all, knowing the signs will help you determine when it is time to replace a metal roof. The five biggest warning signs you should look for include:
Age of Your Roof
New metal roofs can last up to 50 years. With regular roof repairs, you can keep the aluminum or steel panels on your house top for decades. But, eventually, even the most durable sheets will need to be replaced. If your metal roofing insulation or panels are too old, it’s time to replace your metal roof.
Visible Rust and Deterioration of Metal Panels
Rust is the reddish brown coating that forms on exposed metal when moisture mixes with the air’s oxygen. For metal roofs, the formation of rust is a clear indicator that it is time to replace your roof. Although the panels are covered with a protective coating to reduce the formation of rust, it only lasts so long. Weather and other factors can cause erosion of the protective paint.
Aluminum and metal panels are highly durable, but they are not completely impenetrable. Natural and unnatural disasters like wind, storms, snow, and human interference can cause deterioration of the panels. If your metal roof damage is too severe, deterioration of the panels will start to cause problems to the interior and exterior of your building.
Loose Metal Roof Panels
Age, weather, and other factors can cause metal panels to loosen over time. Once this happens, the panels often cannot be resealed onto the roof. Loose panels cannot protect your building from water or other harmful agents. If too many panels are loosening, it is time to look at metal roof replacement options.
Interior Damage from Leaks
If you start noticing damage to the interior of your business, it is time to replace the roof. Metal roof panels are superior protectors and insulators, but if they are no longer protecting your property from external elements, it will quickly show inside your building. Water can get in and damage the walls and ceiling, causing mould and other foundation issues.
Changes to Your Internal Temperature
If you notice a sudden change to the interior temperature and cannot find a valid reason for it, it could be because you need a metal roof replacement. Metal roofs are great insulators that keep your building warm in the winter and cool in the summer. If there is a sudden change in temperature, it could indicate you need to install a new roof.
Your utility bill can also indicate a sudden change in temperature. If you notice your bill is higher or lower than usual, you might need a new metal roof installation.
Metal roofs are highly popular, especially on commercial properties. They are long lasting, durable, and require minimal maintenance. But even the highest quality metal roof will ultimately need to be replaced. To prevent damage to the interior of your building, a metal roof contractor can advise you on all your roofing needs.
