Skylight Cleaning — Canterbury Road, St Kilda West

A skylight sits close to flat, and that changes how it soils. A vertical window sheds water and largely cleans itself in rain. A skylight collects instead: water sits around the frame, the surface stays damp, and moss settles at the edges. That edge matters most: growth packed against the seal holds water where a skylight leaks.

Access was the first problem: the units are roof-mounted, so the work was done from the roof with ladder access. On sheet metal that means treading the fastener lines rather than the pans, which dent under a boot, and keeping tools off the coating — a scratch in it is where rust starts. Growth was cleared off the glass and out of the perimeter.

• Roof accessed by ladder to reach the units
• Walked the fastener lines, not the sheet pans
• Moss and mould cleared from the glazing
• Perimeter, frame and flashing cleared of growth
• Debris removed, not washed into the gutters
• Before and after photographs supplied

• Daylight through the skylights back to normal
• Growth cleared from the seal line, not just glass
• No dented pans or scratches in the roof coating
• Water no longer held against the flashing
