Riverwalk and the Eno River give this page authentic Hillsborough orientation. They do not prove any roof has moss, algae or moisture exposure; the proper content move is to invite owners with visible staining or debris concerns to request an assessment.

The visible issue may be discoloration, yet the cleaning limit is material-based: ARMA guidance says pressure-washer force is not appropriate for algae on asphalt roofing. That distinction matters when older Hillsborough exteriors are being maintained.

Where leaves or surface debris are visible near roof edges and gutters, an estimate can include discussion of Greg Tilley’s published roof-and-gutter service rather than limiting the inquiry to shingles alone.
