Your iron roof works hard to protect your home, but over time, natural elements like moss, mould, and lichen can cause serious damage. Understanding these issues and taking preventive action can save you from costly repairs down the line.
Moss, mould, and lichen may seem harmless at first, but their roots gradually break down the paint surface on your roof. Once these roots reach bare iron, rust sets in quickly, shortening your roof’s lifespan. To prevent this, it’s essential to apply a moss treatment every two years. Regular maintenance helps protect your roof, keeping it in top condition for many years to come.
If you notice nails lifting from your iron roof, you might be dealing with bleeding nails. This occurs due to wind pressure lifting the roof slightly over time, causing nails to loosen. As a result, the iron flexes up and down on the nails, leading to leaks.
Simply hammering down loose nails won’t solve the problem – they’ll just pop back up. Instead, they need to be replaced with longer, thicker nails that have a twist thread for a secure grip. For example, a 60mm smooth nail should be swapped for a 75mm twist-thread nail to ensure a tighter hold.
Regular moss treatments and proper nail replacements are simple yet effective ways to extend the life of your iron roof. Keeping up with these maintenance tasks will help you avoid costly repairs and ensure your roof remains strong and secure for years to come.
