The durability of steel means that steel siding can last 50 years or more–as long as you perform the necessary maintenance. While steel will not become brittle with age, it can become damaged from harsh weather, like hail and falling debris from heavy winds. After big storms, check your steel siding for potential damage to see if any panels require replacing. You also want to keep your siding clean, washing off mud and dirt as necessary. Knowing your steel siding’s warranty is also important–TruLog siding comes with a limited lifetime warranty, and a 30-year paint, fade, and chalking protection.
