The Steps

• 1). Set your ladder to the highest point of the house. Put on your mask. Climb up with your scrub brush and hose, with sprayer set to a medium-hard spray.
  
  
• 2). Wet down the top portion of the shingles. With the water still running over it, scrub the area with your brush, removing all dirt, debris and loose paint. Keep flooding the area as you scrub. Do this for as much of the surface as you can reach, then move your ladder over and proceed across the face of the house.
  
  
• 3). Let the surface dry for at least two days.
  
  
• 4). Apply a thick coat of good acrylic exterior primer, again starting from the top of the house and working your way down. Make sure to completely cover all sides of all the shingles.
  
  
• 5). Give the primer a day to dry, then paint with an exterior latex house paint.
