How Often to Clean a Roof in Beverly Hills and St George
Updated: Sep 29
There is no single yearly rule that fits every roof in St George. Shade, trees and the roof material decide it. Spotless Pressure Kleen sees the same pattern from Beverly Hills through Hurstville to the Shire.
A practical calendar
Autumn: clear leaves from valleys and gutters, and wash the roof if moss has filled the shaded side.
Late spring: treat green growth before summer humidity and storms.
After a heavy storm: check gutters if water came over the fascia or into the eaves.
What changes the gap between cleans
A colourbond roof in full sun grows lichen slowly. A concrete tile roof under gums in Penshurst, Mortdale or Oatley can green up in a couple of years. If the south side stays dark while the street-facing side looks fine, the shaded side is the one to watch.
Roof washing and gutter cleaning go together. Blocked gutters are covered in our gutter cleaning guide. For Hurstville and the Shire, see the local roof cleaning guide.
How often should a roof be cleaned in Beverly Hills?
A house under trees in Beverly Hills, Hurstville or Penshurst often needs a roof clean every two to three years. A shaded roof, or one that stays green on the south side, is worth doing sooner.
When is the best time of year to clean a St George roof?
Autumn, after the leaves drop, is the most useful time. Late spring is the other good window, before the summer storms. After a storm, clean the gutters if water has overflowed.
