Roof Washing & Pressure Washing Wollongong

Wollongong homes get it from both sides: damp shade off the escarpment grows moss, mould and lichen, and salt air off the beach dulls paint and leaves a film on everything. Illawarra Maintenance Group soft washes roofs and pressure washes driveways, paths, walls and decks across Wollongong, then treats the growth so it stays away longer.

    Roof washing

    We soft wash roofs. That means low pressure and a cleaning solution that kills moss, mould and lichen at the root, instead of blasting the surface. It is safer for tiles, ridge capping and Colorbond, and the roof stays clean for longer than a high pressure clean. Black streaks, green moss on the shady side and orange lichen on tiles are the usual problems we see under the escarpment.

    We focus on roof washing. Small roof repairs, such as replacing broken tiles and minor repointing, can be done while we are there. We do not offer full roof restorations or replacements, so we will never push you towards a bigger job.

    Pressure washing

    • Driveways and paths, including oil and tyre marks
    • Retaining walls, steps and garden edges
    • Pool surrounds, patios and decks
    • House walls, render and brick, using soft wash where pressure would do damage
    • Fences and outdoor areas for real estate photos or end of lease

    Why Wollongong homes need it more often

    Houses in Mount Ousley, Keiraville, Figtree and Mount Keira sit in the escarpment's shadow for much of the day. Surfaces stay damp, so moss and mould come back faster than on open coastal blocks. Near the beach in North Wollongong and Fairy Meadow, salt and sand build up on paint and glass. We will tell you honestly how often your place needs doing, even if that means less often than you thought.

    Questions from Wollongong homeowners

    Yes. Soft washing uses low pressure, so it does not lift or crack tiles or strip the glaze the way a high pressure clean can.

    It depends on shade and trees. Open, sunny roofs often stay clean for several years. Roofs under the escarpment or big trees may need a wash sooner. We will give you an honest idea at the quote.

    We work outside only. We will confirm water access when we quote.

    Yes. Tell us your photo or open home date and we will plan around it.

    Yes. We come out, get up on the roof, measure properly and give you a fixed written quote, free.

    Our Testimonials

    I highly recommend Mathew, the workmanship was exceptional, very professional and everything was left neat and tidy. He explained how he approached the job and found a problem with the back gutter which took longer than expected but stuck by his quote. He is an absolute professional and gentleman.

    Stephen James

    Matt did a great job cleaning our gutters and doing a full replacement of our gutter guards which had been installed incorrectly. He also treated the lichen on our roof and dealt with a wasp nest complementary. He was friendly, professional and really easy to deal with. We're really happy with the work he did.

    Lisa Francis

    I had been looking for a solution to birds gaining access to the inside of my roof from the gutters. After some messages and photos with Mathew we hashed out a solution and got a quote. Really great job done here and I would recommend Mathew if you have a similar issue with birds or leaves. He got his drone up and was able to really show me the awesome work he did.

    Ethan Jones

    We have just had our box gutter and gutters thoroughly cleaned by Matt. He also provided drone photos and detected a rusted hole and repaired it until we were able to call a roofer. The service was prompt and affordable. We would recommend their services.

    Valerie Sherrell

    I had the best experience. They are so professional, organised, honest and knowledgeable. Mathew did an incredible job with cleaning my gutters. Would definitely recommend.

    Noura

    Mathew was a pleasure to deal with. Great communication, super professional and we are really happy with our gutter guards. Highly recommend.
