Indicative ranges for roof cleaning, house washing, driveway cleaning and roof restoration from the Gold Coast to Byron Bay, with the five things that move you inside the range and the cheap quote that actually costs more.
Short answer: A roof-safe soft-wash on a single-storey home runs $450 to $900, a full exterior reset (roof, walls, gutters) $900 to $2,200, and a roof restoration with repointing and recoating $3,000 to $8,000 or more. The five things that move you inside those ranges are size, surface, access, condition and repairs.
Every range below is from real coastal jobs between the Gold Coast and Byron Bay. A pressure-only roof clean sits at $200 to $450, which is the cheapest line and also the riskiest, because the visible mould comes off but the spores stay in the surface and the stripes are back within a wet season. A soft-wash roof clean on a sound single-storey tile or Colorbond roof sits at $450 to $900, which is where the work actually holds for two to three years. A full house wash on render or weatherboard sits at $350 to $750, and a driveway clean with proper run-off containment sits at $300 to $600. A roof restoration, which is the repair pathway rather than a clean, runs $3,000 to $8,000 or more depending on whether you also recoat. Bundling a roof clean, house wash and gutters into one visit usually saves around 15 to 20 percent on the separate call-outs because the crew is already on the property with the gear set up.
Size and surface area is the biggest single lever. A double-garage roof and a four-bedroom roof are different jobs, even if both are tile. The surface itself is the second: tile, Colorbond, render, weatherboard, concrete and aggregate each want their own method, and some are slower than others. Access and pitch is the third: a single-storey with a gentle pitch is the cheapest end, a two-storey or a steep pitch needs harnesses and platforms and costs more for good reason. Condition is the fourth: a maintenance wash is fast, heavy lichen and salt staining means longer dwell-time, repeat passes or a repair pathway first. Repairs needed is the fifth: a clean is one price, slipped tiles or failed pointing is a different scope, and an honest quote separates the two so you can compare and choose. The estimator on this site walks you through all five in under a minute.
A $250 roof clean looks like a win until you do the maths over five years. A pressure-only blast at $250, repeated every season because the mould keeps coming back, is $1,000 a year and a Colorbond roof with the protective coating chalked off after the second pass. A roof-safe soft-wash at $700 every two to three years is $233 to $350 a year and a roof with its surface intact. Cheap once or properly priced and held, on this coast, the slow win pays. Where there is real value in a low quote is when the scope is genuinely smaller, the operator is local with no travel cost, or you are bundling work that is already on the property. Ask what makes the price low. A straight answer is fine. A vague one is a tell.
