There is a simple, inexpensive method that will allow you to safely work off your roof and access the areas you need to paint.

  1. 1

    Mark the centre of your 5 by 10 cm (2 by 4 inch) board, using a tape measure and pencil. The centre of a 2.4 m (8 foot) long board is 1.2 m (48 inches). Place a straight edge next to your pencil marks. Use your pencil to trace a line up against your straight edge.

  2. 2

    Cut your 5 by 10 cm (2 by 4 inch) board in half with the circular saw.

  3. 3

    Clamp your two, 1.2 m (4 foot) sections together in the shape of an L. Lay one board flat with the 10 cm (4 inch) side facing up, and set your second section of wood directly up against the side of the first board, with the 5 cm (2 inch) side facing up. The 10 cm (4 inch) side of the second board should be up against the 5 cm (2 inch) edge of the first board.

  4. 4

    Drive 7.5 cm (3 inch) deck screws, with your drill, through the 10 cm (4 inch) side of the second board, into the 5 cm (2 inch) edge of the first board. Space your screws a maximum of 15 cm (6 inches) apart.

  5. 5

    Set an extension ladder up against your house in the area that you will be working. Take your drill, at least six 7.5 cm (3 inch) deck screws, and your L board up the ladder with you. Set your L board on your roof with the tallest side sticking up. Slide your board over so that it is a minimum of 60 cm (2 feet) from the side of the house or overhang you will be working on. You do not want to be positioned too close, or too far away.

  6. 6

    Drive your deck screws through the face of the bottom board and into the roof.

  7. 7

    Carry your second extension ladder up to your roof and set the feet of your ladder up against the portion of board sticking up off the roof. You will now be able to climb onto your board and extend your ladder up your roof. Make sure your ladder is locked into position before you get on it.

Tips and warnings

  • As a more expensive alternative, purchase two roof jack brackets, screw them to your roof 1.2 m (4 feet) apart, and lay a 1.8 m (6 foot) long, 5 by 15 cm (2 by 6 inch) board across the brackets.The feet of your ladder will rest on the board.
  • Use a clear roof patch in a tube to seal the screw holes when you remove your anchor board or brackets.
