To work on a roof, you must first get there safely. Although setting up a ladder may seem simple, skipping some basic steps could land you on the ground -- or in the emergency room. Begin by carefully checking the ladder for any weak or damaged areas. Set the ladder on firm, solid ground to avoid sinking or tipping. Always attach the ladder to a fixed object near the roof edge to ensure that it is immobile. Enlist the aid of a helper to hold the ladder for added protection against slippage.
Inspect the roof for an area containing a solid gutter or other fixed object for ladder attachment. Have a helper aid in carrying the ladder to this area. Set the ladder on firm, level ground to ensure that the ladder feet do not sink and move while you climb. Ensure that the ladder is sitting straight. Leave three feet of the ladder extending above the edge of the roof.
Measure the approximate ladder length from the ground to the roof edge with a tape measure. The base of the ladder should be positioned one foot from the roof edge for every four feet of ladder length. Divide the total ladder length by four. Position the base at the appropriate distance from the building. Place a wooden block under the base for added support. When no tape measure is available, estimate the ladder length by counting the rungs, which are about one foot apart.
Stand on the bottom step of the ladder with both feet securely on the rung. Press down firmly with both feet to set and secure the ladder into the ground. Climb the ladder until you reach the roof edge. Do not advance above the top three ladder rungs.
Hook one end of a bungee cord to the lip of the gutter. Wind the cord tightly around the leg of the ladder. Fold the cord completely across the ladder and back around in a complete circle around the ladder. Hook the cord to the lip of the gutter on the opposite side of the ladder.
Face the ladder and climb down carefully. Use both hands and keep your feet in the center of the rungs as you descend.
