Installing aluminum gutters yourself is not a project for the faint of heart. It requires an advanced level of engineering skill and knowledge of the local building codes and regulations.
In addition, you may need special tools, such as a ladder that is strong enough to bear your weight and a hacksaw if you are cutting the gutter pieces to length.
If you have at least some experience in home improvement projects, have enough time to research and prepare for the job, and access to all necessary tools, then you may be able to install aluminum gutters yourself – however, it is highly recommended that you leave this task to a professional installer if possible.
