Metal Roofs 101 and How to Maintain Them
Did you know metal roofs can last up to 60 years? That’s right; these roofing systems have more than double the life expectancy of a shingle or tile roof. In Florida, metal is always a popular choice because of two reasons. 1st, metal will keep your house cooler, resulting in a 20% reduction in energy costs; and 2nd, metal roofs can withstand wind speeds up to 165 mph with a standard installation and up to 215mph with enhanced systems; hello, hurricane season. Metal roofs are relatively low-maintenance, and you rarely must worry about mildew or mold, as you do with other roofing systems. Plus, they are one of the most fire-resistant options available.
Many metal roofing systems exist, but 5v or Standing Seam are the most popular residential types. 5v metal roofing systems are the more economical choice, as the installation is not as complicated as standing seam systems. 5v systems are more affordable because the fasteners are exposed, meaning you can see the screws. These fasteners go directly through the metal panels, which prevents thermal expansion and contraction. This is one of the key differences between 5v and standing seam systems. It is important to note that both 5v and standing seam systems require regular maintenance. However, since the fasteners are exposed on a 5v system, every 15 years, you will need to have your fasteners inspected by a roofing professional.
Standing seam roofs are known to last longer than 5v metal because they are designed for thermal expansion and contraction, making them more durable and weather resistant than 5v. Because standing seam fasteners (screws) are not exposed, there is less maintenance than a 5v metal roof. Standing seam is a more complex roofing system and installation can take up to a week to complete on standard size buildings. Compared to a 5v metal roof, the complexities and unique features of a standing seam metal roofing system add up, resulting in a higher price tag. For many homeowners, the upfront cost is worth it since these roofs require very little maintenance, and they are designed to keep your home cooler in the summer and warmer in the winter.

Ten Tips to Maintain Your Metal Roof
Maintaining a metal roof is essential for ensuring its longevity and performance. Here are some steps you can take to effectively maintain a metal roof:
- Regular Inspections: Conduct visual inspections of your metal roof at least twice a year, ideally in the spring and fall, to check for any signs of damage, rust, loose screws, or debris buildup.
- Clean Gutters and Downspouts: Ensure that gutters and downspouts are clear of debris such as leaves, branches, and dirt. Clogged gutters can cause water to backup and potentially damage your roof.
- Remove Debris: Clear any debris such as leaves, branches, or other organic matter that may accumulate on the roof surface. This prevents moisture buildup and potential damage.
- Trim Overhanging Branches: Trim back any overhanging branches that could potentially scratch or damage the surface of the metal roof, especially during windy conditions.
- Address Rust Spots: If you notice any rust spots on your metal roof, address them promptly to prevent further corrosion. Use a wire brush to remove the rust, then apply a rust-inhibiting primer and a matching paint to seal the area.
- Repair Sealant and Caulking: Check the sealant and caulking around vents, chimneys, skylights, and other roof penetrations. Repair any cracks or gaps to prevent water infiltration.
- Check for Loose Fasteners: Inspect the fasteners (screws or nails) holding the metal panels in place. Tighten any loose fasteners to prevent panels from becoming dislodged during high winds.
- Prevent Ice Dams: In colder climates, install snow guards or heat cables to prevent the formation of ice dams, which can damage the roof and gutters.
- Avoid Walking on the Roof: Minimize foot traffic on the roof to prevent accidental damage to the metal panels. If you need to access the roof for maintenance or repairs, use proper safety precautions and walk only on designated walkways or supports.
- Professional Inspection and Maintenance: Consider hiring a professional roofing contractor to perform a thorough inspection and maintenance of your metal roof, especially if you’re not comfortable or equipped to do it yourself.
By following these maintenance tips, you can help prolong the life of your metal roof and ensure that it continues to protect your home or building effectively.
