1. Nail a row of roof brackets about 18 in. up from the eave and about 4 ft. apart. Position the brackets directly over a rafter or truss (Fig. A). Install each bracket by lifting a shingle tab and sliding the bracket under it. Then pound 20d common nails into each slot, making sure they hit the rafter or truss.

2. Lay a 2x6 plank across the brackets and attach it to the brackets with screws. Make sure the 2x6 extends at least 6 in. but not more than 12 in. past the end brackets. Set another row of roof brackets and planks about every 8 ft. up the roof, or as close together as needed to make your work safe and convenient.

3. Strap on the safety harness according to the manufacturer’s instructions. Tighten the straps for a snug fit. Double-check all the buckles before you go onto the roof.

4. Fasten the roof anchor to the peak according to the manufacturer’s instructions. We drove six 1/4 x 2-in. lag screws through the roof boards into the rafters. Predrill 3/16-in. holes. Then use a wrench to tighten the lag screws.

5. Clip the end of the safety rope to the ring on the roof anchor. Then clip the lanyard to the D-ring on the back of
the harness. Squeeze the rope-grab and slide it along the safety rope to reposition the lanyard on the rope as you move around the
roof.

6. Relocate or remove brackets by pounding up to slide them off the nails. Keep the lowest set of planks in place until
you’re done on the roof. Store tools and supplies in a bucket hung from a roof bracket.
