Roof & Gutter clean
Protect your roof. Keep your drainage working.
Your roof is the most exposed surface on your property and, for most homeowners, the least inspected. Moss, lichen and biological growth hold moisture against roofing material and accelerate deterioration. Blocked gutters redirect water into fascia, walls and foundations. Both are preventable with the right treatment on a regular schedule. Clean by Design is certified to work safely at heights. Roof work is not a service we approach casually.
What happens when Roofs are left untreated
Moss and lichen trap moisture against tile and metal surfaces, breaking down mortar, coating and protective finishes
Biological staining reduces solar reflectance and increases heat absorption
Gutters blocked with debris cause overflow into fascia and wall cavities
Pooling water at foundations from inadequate drainage creates long-term structural risk
Neglected roofs affect property presentation and can become a flag for building inspectors at sale
How we clean roofs and gutters
We inspect the roof before work begins, noting tile condition, ridge capping, any cracked or displaced tiles, and the extent of biological growth. Biological treatment is applied first and allowed to work before any rinsing. Gutters are cleared of debris, downpipes checked for flow.

Common questions
Do I need to be home while you clean my roof?
Not necessarily. We need safe access to the property and ideally a contact number in case we need to raise anything observed during the clean. If you prefer to be present, we accommodate that.
How long does a roof and gutter clean take?
Most residential properties take two to three hours. Larger roofs or those with significant moss and lichen accumulation take longer. We advise at quoting stage.
How often should gutters be cleaned?
At minimum twice per year, typically spring and autumn, for properties with tree canopy above or near the roofline. Properties without significant tree cover may manage with an annual clean.
Can you repair cracked or broken tiles?
Tile condition is noted and photographed during the clean. We do not carry out tile repairs, but we will document any issues clearly so you can arrange the right trade.
