  • Roof debris like leaves and dirt can trap moisture and lead to the deterioration of your roofing materials, bringing down the lifespan of your roof.
  • Clogged gutters and downspouts resulting from the accumulation of dirt and debris can lead to water leakage.
  • A stained or discoloured roof will remove the curb appeal of your property, and roof cleaning can help you present your space & overall appearance.
  • Regular roof cleaning can help you detect any underlying issues and get them repaired beforehand.

  • Colorbond / Metal Roofing: It is durable and can go without cleaning for ten to fifteen years.
  • Tile Roofing: Tile roofing offers less resistance to harsh weather conditions than metal roofing and requires roof cleaning every seven to ten years.
  • Slate: They are prone to algae growth and require cleaning every 7-10 years.

Surrounding Vegetation

If there are overhanging trees around your roof, a lot of waste will accumulate on your roof in terms of leaves, twigs, small branches, etc. All of which, if left unattended, can –

  • Lead to algae and mould growth.
  • Trap moisture and lead to water damage.
  • Block your downpipe and gutters.

If you have a lot of trees around your home, clean your gutters and roof regularly on your own and/or schedule professional roof & gutter cleaning services frequently.

Structural Factors

Certain structural elements of your roof also determine the ideal cleaning frequency of your roof.

  • Roof Slope: Steeper roofs allow accessible water and debris flow, whereas flat roofs are prone to waste/water accumulation.
  • Gutters & Downpipes: Clear gutter & downpipes will effectively channel the water and debris off your roof and away from your property, but blocked gutters and downpipes will lead to overflow & water damage.
  • Design Features: If your roof has additional design elements like valleys, dormer windows, HVAC equipment and skylights, you will need more frequent cleaning as such structures trap dirt and debris including bird nests & debris.
