Whats the best plastic, aluminium or steel?
Most gutter guards work to a degree. The most important thing you should think about is the life of the guard. Plastics are not made for the Australian conditions as they expand and contract. This causes them to crack, bubble and most are highly flammable. We remove most plastic guard within 5-6 years. Steel is great but needs to be an Australian Made quality steel in order to be better resistant to rusting, or needs to be treated after the expansion process. Gumleaf gutter protection is treated after the expansion process, therefore resisting the tendency to rust.
