Roof renovation is an extraordinary maintenance project, meaning it doesn't fall under the scope of work that can be performed using a lifeline. It is, in fact, suitable for performing ordinary maintenance work, such as radio and television antenna repairs, Faraday cage maintenance, maintenance of roofing systems, re-roofing/replacing waterproofing membranes and sheaths, gutters cleaning, satellite dish repairs, solar panel or photovoltaic system installation or maintenance, etc.
