Cleaning & Growth Profile
Harkness Roofing & Weather Profile
What We See in Harkness
A clean roof is one of the clearest visual signals of a maintained property. The difference in street appeal between a moss-covered roof and a clean one on the same house is substantial — it changes the perceived age and condition of the entire building.
Why It Happens
The cleaning interval required for a given roof is a function of tree cover, aspect, rainfall, and tile type. A heavily shaded terracotta roof in a high-rainfall suburb may need cleaning every three to four years. A north-facing concrete tile roof in an open block may go eight to ten years.
How We Fix It
Cleaning a moss-heavy roof in multiple passes is more effective than a single high-pressure blast. A first pass at moderate pressure lifts the bulk of the growth; a second pass at lower pressure removes the remaining rhizoids from the tile surface without driving them deeper.
