Some people use harness all the time, and in some cases they’re required by government safety codes. A ground ladder is one that stands on the ground and is used to get up to the roof. This is the typical ladder that most people are familiar with. Aluminum ladders are recommended because they’re light in weight and easy to handle, although aluminum ladders do conduct electricity and are very dangerous around electrical wires. Ladders must be put up properly or they can be very hazardous. Ladders will blow off the house if not tied on, and are typically tied to a rain gutter, or a nail or hook driven into the fascia. They must not be set up too steeply, or not steep enough (at too great an angle), and must be put up plumb (perpendicular to the force of gravity – not leaning sideways). Although smaller ladders can he pin tip by one person, longer ladders should be put up by two people, for safety’s sake.
Replacing roof is serious business so hire quality roofers.
