Roof Pressure Washing in Cobham — When It's Appropriate
Pressure washing has a place — concrete tiles with very heavy organic build-up, flat felt roofs and certain commercial substrates can tolerate controlled pressure. For most Cobham homes, however, low-pressure soft washing is safer and longer-lasting. We'll honestly tell you which your roof needs.
What's included
- Honest advice — we'll recommend soft wash where pressure washing would damage tiles
- Variable-pressure equipment with rotary surface cleaners where suitable
- Trained operators only — no subcontractors
- Full surface protection and runoff management
Our process
-
Step 1
Tile assessment
We identify tile type, age and condition to decide whether pressure washing is safe.
-
Step 2
Test patch
A small inconspicuous patch is cleaned and inspected before the full job proceeds.
-
Step 3
Controlled wash
Pressure is dialled to the minimum that removes growth without disturbing the tile surface.
-
Step 4
Biocide finish
A post-clean biocide is always applied to slow regrowth.
Frequently asked questions
Does pressure washing damage roof tiles?
It can. On concrete and clay tiles older than 15 years, high pressure removes the protective surface coating and accelerates moss regrowth. We assess every roof individually.
When is pressure washing the right choice?
Modern flat roofs, garage roofs, render and patios benefit from controlled pressure cleaning. Pitched tile roofs almost never do.
