Roof Pressure Washing Services — Island-Wide, Sri Lanka
Sri Lanka's humidity and rainfall give moss, algae, and black streaks everything they need to take hold on a roof — especially on shaded slopes or roofs surrounded by trees. Beyond how it looks, built-up growth holds moisture against the roof surface longer than a clean roof would.
Pressure washing works, but the pressure and technique matter. Too much pressure aimed the wrong way can lift or crack tiles and force water under them. Our approach uses controlled pressure suited to your specific roof type rather than one setting for every job.
What's included in our roof pressure washing service
- Inspection of the roof surface and tile condition before starting
- Clearing loose debris from the roof
- Washing the roof surface with pressure and technique matched to the roof material
- Rinsing to remove loosened moss, algae, and dirt
- Final check of the roof and surrounding gutters
When to consider roof washing
If you can see green or black patches spreading across your roof, or the roof looks visibly duller than when it was new, it's worth having it assessed.
Frequently Asked Questions
Does pressure washing damage roof tiles?
It can, if the pressure and technique aren't matched to the roof material — that's why we assess the roof first and adjust our approach rather than using one setting for every job.
How often should a roof be pressure washed?
It depends on shade, humidity, and how quickly moss and algae return — many roofs benefit from a wash every one to two years.
Will pressure washing remove moss and algae permanently?
It removes what's currently there. Regrowth depends on how much shade and moisture the roof gets afterward, so some roofs need cleaning again sooner than others.
Can you wash roofs with solar panels installed?
Yes — we work carefully around existing solar panels, and can quote panel cleaning as part of the same visit.
