Pennsylvania is elevated suburb with above-average wind exposure on north-west faces. Elevated position with good drying reduces moss establishment somewhat; north-facing slopes still require standard 3-year treatment cycle. Free survey, no call-out fee. Call 01392 759 295.
Elevated suburb with above-average wind exposure on north-west faces — victorian and edwardian Pennsylvania Road and surrounding streets. Elevated position with good drying reduces moss establishment somewhat; north-facing slopes still require standard 3-year treatment cycle.
Pennsylvania’s specific characteristics create distinct moss removal requirements. The victorian and edwardian housing stock in Pennsylvania presents conditions that differ from Exeter’s post-war suburbs, and the correct specification for each job reflects the age, construction method and local exposure of the property.
Elevated position with good drying reduces moss establishment somewhat; north-facing slopes still require standard 3-year treatment cycle. We carry out free surveys across Pennsylvania, Exeter and provide written fixed-price quotes with no call-out fee.
Pressure washing is the most common roof treatment error we encounter on Pennsylvania survey visits. The appeal is immediate visual transformation — a pressure-washed roof looks clean on the day. The reality is that pressure washing removes the weathered surface layer from both concrete and natural tile, creating a more porous surface that allows moss spores to establish faster than on an intact weathered surface. On Pennsylvania’s Welsh slate stock, pressure washing strips the protective oxidised surface entirely, exposing fresh stone that weathers differently from the surrounding original material. The correct treatment method is low-pressure biocide application — the biocide kills the moss chemically, the die-back occurs over 2–6 months as natural weathering carries the treated growth away, and the tile surface is preserved intact. Re-establishment rates after biocide treatment are consistently slower than after pressure washing because the surface retains its natural weathered profile.
