Roof Cleaning - covering Oreston and the PL9 area
Oreston weather does a number on exterior surfaces, and roof cleaning is usually the first thing to suffer. Slate, stone and lime render all want a softer hand than the standard pressure wash.
Why Oreston matters for this kind of work
Oreston weather does a number on exterior surfaces, and roof cleaning is usually the first thing to suffer. Slate, stone and lime render all want a softer hand than the standard pressure wash.
Old boatbuilding village on the Cattewater, which shapes how exterior cleaning here actually plays out. If you can see Plymstock from the end of your road, we cover you.
What good roof cleaning looks like here

- 2Mechanical scrape before any softwash, debris bagged - never swept into estuary village gutters
- 3Hip-tile and verge tiles inspected during the scrape on slate and concrete tile
- 4Solar arrays masked to keep softwash off the panels on newer Oreston builds
- 5Valley flashings checked and cleared before the main rinse on stone cottages and 1930s bungalows
