Unwashed Areas



An unwashed area is any part of your home that is not naturally washed by rain.

Materials used to weatherproof your house will normally have warranty requirements by the manufacturer that they are washed on a regular basis.

How can you determine what is an unwashed area?

If water does not fully wet the area when it rains, it is an unwashed area. For example, the underneath of your guttering may get wet, but it is insufficient to wash away salt and other contaminants which build up. This is particularly critical for iron or steel roofs and gutters.
