Do aluminum rain gutters or steel rain gutters last longer?
Aluminum rain gutters have a higher susceptibility to damage than steel. This is partly because of their lightweight nature and lower resilience. They easily get damaged during harsh weather. Improperly placed ladders or other poor handling during maintenance easily results in dents or deformity.
However, steel gutters are heavy and sturdy. This contributes to high tensile strength and higher durability. Steel gutters are a good choice if you live in an area prone to hurricanes or tornadoes. Well-maintained aluminum gutters will last from 15 to 30 years. Steel gutters can last up to 50 years, especially if you use an excellent coating system.
