Roof Cleaning In Melbourne

Roof cleaning is priced on roof area including the pitch factor, the access around the property, the tile or sheet type, and how established the growth is. A single-storey concrete tile roof with light algae and clear ladder access is the straightforward end of the range. A steep double-storey roof, a house on a sloping block, or a roof carrying years of thick lichen that needs a stronger application and a second pass all move the figure up. The gutter clear-down after the clean is part of the job rather than an add-on. Send photos of the roof and of the house from the street to 0430 392 100 for a written price.

High pressure absolutely will, which is why we do not use it on roofs. The colour and weather resistance of a concrete roof tile sit in a thin cement-rich surface layer, and a high-pressure lance strips that layer off with the lichen, leaving the tile porous, chalky and shedding grit into your gutters for years. Terracotta faces a different risk, being brittle underfoot and prone to water being driven up under the laps. Metal roofing can be dented and its coating scoured. TopTier treats the growth chemically and rinses at controlled low pressure, so the water only removes what is already dead.

Most tile roofs across Melbourne's south east want attention every three to five years, and shade and tree canopy decide where in that range your roof sits. A roof under mature eucalypt, tea tree or pine, common through Frankston South, Langwarrin, Mount Eliza and Somerville, will grow moss and lichen considerably faster than one in open sun. Coastal properties tend to need metal roofing attended to more often for salt film and streaking rather than for growth. The signs to watch for are dark patches spreading on the southern pitch, visible moss along the tile laps and granular grit collecting in the gutters.

Yes, the gutter clear-down is part of every roof clean rather than an optional extra. Any roof clean sheds moss, lichen and grit into the valleys and guttering, so leaving it there would block the downpipes at the first decent rain and push water back under the eaves. Valleys, gutters and downpipes are cleared and flushed once the roof work is finished. If your gutters need a full service in their own right, with a photo report and a proper check of the brackets and falls, that is covered under gutter cleaning and can be quoted into the same visit at 0430 392 100.

Killing the growth at the root, which is what the treatment stage does, already gets you far longer than a blast that only removes the visible layer. Beyond that, a protective treatment can be applied after the clean to slow regrowth on roofs that are going straight back under the same shade and canopy. It is worth being straight about the limits: no treatment makes a roof permanently self-cleaning, and a north-facing roof in full sun will always stay clear longer than a south pitch under a tea tree. What treatment buys you is time between cleans. We will tell you whether it is worth it for your particular roof.

Yes, and metal roofing is a different job to tile. Colorbond and similar coated steel roofing does not grow lichen the way porous tile does, so the work is about salt film, tree sap, dust streaking and the dark tiger-striping that builds along the ribs, particularly on the coastal side through Mount Eliza, Aspendale, Seaford and Patterson Lakes. It is washed with the appropriate detergent at low pressure so the coating is not scoured and the sheets are not dented, and rinsed thoroughly. The same care applies to Colorbond carports, verandah roofs, sheds and fencing, which are often quoted into the same visit.
