Why Treat Your Roof in Wellington?

Moss, algae, and mould aren’t just unsightly; they can cause significant damage to your roof. Wellington’s coastal weather can accelerate roof degradation, so regular treatment is essential to avoid leaks, increased maintenance costs, and structural issues.

Prevent Roof Damage

Remove moss and algae that lift tiles, block drainage, and cause water penetration.

Extend Roof Life

Stop organic growth that breaks down roofing materials and accelerates deterioration.

Improve Energy Efficiency

Clean roofs reflect heat better, reducing cooling costs and improving home comfort.

Maintain Property Value

A clean, well-maintained roof enhances curb appeal and protects your investment.
