A rough rule
Many Central Florida homeowners wash the house about once a year and the driveway once or twice a year. Roofs usually go longer between cleanings. Homes under heavy shade or near water need it more often.
Signs it's time
- Green or black streaks on the north and shaded walls
- Black streaks running down the roof
- A gray, dull driveway with dark tire paths
- Green on the pool cage beams or vinyl fence
- Dark tiger stripes on the gutter faces
Plan around events
Wash before painting, before listing a home, before an HOA inspection, or before guests come in for the holidays. Washing first also lets you see what really needs repair.
