Metal roofs are a popular choice for homeowners in Hawaii due to their durability, life expectancy in tropical environments (30-50 years) and low maintenance requirements. However, like any other roofing material, metal roofs require some level of maintenance to keep them in good condition and prolong their lifespan. In this blog post, we’ll discuss some tips for monitoring your metal roof for signs of degradation and prolonging the life of your roof.
Monitor Your Roof Regularly
The first step in maintaining your metal roof is to monitor it regularly for signs of degradation. Here are some key things to look for:
Rust or corrosion – Metal roofs can rust over time, especially if they are exposed to moisture or other corrosive elements. The eaves and valleys are usually the first places to rust. Look for any areas of rust or corrosion on your roof, and address them as soon as possible to prevent further damage. Painting your roof is an excellent way to prevent and treat rust and corrosion.
Loose, missing or deteriorated fasteners – Metal roofs are typically installed using screws or other fasteners. Over time, these fasteners can become loose or fall out, which can lead to leaks or other issues. Metal roof fasteners also incorporate neoprene rubber washers to seal out water. These washers and fasteners typically have a life expectancy that is about half of the roof’s life and may need to be replaced depending on their condition and past maintenance. Check your roof regularly for any loose, missing, or deteriorated fasteners, and replace them as needed.
Cracks or other damage – Metal roofs can also develop cracks or other damage over time, especially if they are exposed to extreme weather conditions. Look for any signs of damage on your roof, and address them promptly to prevent further issues.
Clean Your Roof Regularly
Another important aspect of metal roof maintenance is regular cleaning. Keeping your roof clean is important because dirt and microbial growth can accumulate on the roof, leading to potential damage and degradation of the metal. Here are some tips for keeping your metal roof clean:
-
Use a soft-bristled brush or broom – When cleaning your metal roof, use a soft-bristled brush or broom to avoid damaging the surface of the roof.
-
Use a mild cleaning solution – To remove dirt and debris from your roof, use a mild cleaning solution such as water and mild detergent. Avoid using harsh chemicals or abrasive cleaners, as these can damage the surface of the roof.
-
Power washing – Power washing is a viable way to clean your roof, but it is important to use caution when doing so. Power washers are bulky and heavy, so unless you have the proper extensions needed, it may be difficult to get them up high enough to reach the entire roof. If sprayed too close, they may also dent the roof or remove protective coatings.
Maintain Penetration Points
In addition to monitoring and cleaning your metal roof regularly, it is also important to maintain all penetration points, including plumbing vents. Fluid applied sealant under tar foil (bitumen tape) or rubber boots work best for flashing on metal roofs. Inspect all penetrations at least every 2 years and check for signs of damage or wear and replace or improve as needed.
Paint Your Roof To Prevent Or Treat Rust & Corrosion
Painting your metal roof can be an effective way to treat and prevent rust and corrosion. Applying a coat of paint to your metal roof can create a protective barrier that helps to seal out moisture and prevent rust and corrosion from forming. Before painting your metal roof, make sure to clean it thoroughly and remove any rust or corrosion using a wire brush or rust converter. Choose a high-quality paint specifically formulated for metal roofs, and follow the manufacturer’s instructions for application.
Conclusion
By following these tips, you can keep your metal roof in good condition and avoid costly repairs or replacements in the future. Remember to monitor your roof regularly, clean it regularly, maintain all penetration points, and address any issues promptly. By taking these steps, you can prolong the lifespan of your metal roof and enjoy its benefits for years to come.
