Start With the Problem, Then Choose the Service
If the roof has a few green patches, begin with treatment timing and the difference between cleaning and treatment. If water spills over a gutter, start with blockage signs and inspection frequency. If a walkway is slick, learn why organic film develops before assuming every dark mark needs maximum pressure.
Guides explain what cleaning can change, what may remain, and when repair should come first. They do not replace an inspection by a roofer, painter, drainage professional, or other qualified trade when the underlying material is failing.
The most useful maintenance decision may be cleaning, treatment, repair, monitoring, or doing nothing yet.
