Metal roofs can last between 40 and 70 years. Another advantage of a metal roof is its durability. Metal roofs are often better able to withstand extreme weather than other types of roofing materials. Additionally, metal roofs can help lower the cost of your energy bills by reflecting heat from the sun away from your house.
A metal roof does still need maintenance, however. If you want your metal roof to reach its maximum possible life expectancy and continue to protect your home as well as it can, you need to take care of it, too. But what maintenance do metal roofs need?
Keep Your Roof Clean
Over time, dirt and other particles, such as pollen and mildew, can build up on your roof. Metal can also start to rust or become water-stained. Sometimes there are chemicals in the air that can be deposited on your roof, such as by acid rain. These can actually end up harming your roof and impacting its longevity if left alone.
How to Properly Clean a Metal Roof
You may be able to clean your roof with just water. However, you may need a cleaning agent and a cleaning tool like a microfiber cloth to get off more stubborn stains. If you do need to use a cleaning solution, you may want to dilute it with water in order to make sure it’s safe to use on your roof. Car washing soap, dish soap, and laundry detergent may all be used at a 5% cleaning solution per gallon of water.
Clean Branches and Leaves off the Roof and out of Gutters
Make sure to keep branches and leaves off your roof. If there are trees near your home, then leaves and branches can accumulate in the gutters as well as in valleys on your roof. The branches don’t add to the aesthetic appeal of your home and can also scratch the paint on your metal roof if not removed.
Trim Your Tree Branches
If you have trees near your home, it’s important to keep them in good condition. Trim any branches that hang over your roof. This will prevent them from falling onto your roof and potentially damaging it in the first place.
Keep Metal Away from Your Roof
Although it’s unlikely that other metal will touch your metal roof, it’s important to ensure that your roof doesn’t come into contact with it. Contact with foreign materials could cause your roof to stain or even to degrade and deteriorate more rapidly than it would otherwise. This is why what you use to clean your roof matters. Metal tools could scratch or corrode your roof and brushes with hard bristles could damage the paint.
Touch up the Paint
Typically, the paint on a metal roof can last up to a decade. However, if it’s been that long or you notice chips in the paint, a fresh coat of paint can help to fix small blemishes on your roof. Fresh paint may also help remove corrosion and even small holes. Keeping the paint refreshed when necessary can also help your roof as a whole last longer.
Schedule a Professional Inspection
Scheduling an annual inspection of your metal roof can help prolong its life by identifying any problems more quickly. Professional roofers will know what they’re looking for and can more easily spot scratches, corrosion, leaks, dents, and more that you may have missed. After a professional inspection, the roofing company can then repair any damage they find.
