Your roof makes up to 40% of your home’s visible exterior. Over time, baking under the harsh Australian sun combined with moisture buildup leads to cracked tiles, faded metal sheets, and extensive moss or lichen growth.
At Grand Design Painting, we don't just spray a quick coat of paint over a dirty roof. We deliver a comprehensive, engineered 5-step roof restoration system specifically tailored for concrete tile, terracotta, and metal (Colorbond) roofs across Camden, Campbelltown, and the wider Macarthur region.
By pairing meticulous commercial preparation with Dulux Acratex Next Gen Roof Membrane, we restore structural integrity, improve your home's street appeal, and reflect solar heat to keep your cooling bills down.
The Grand Design 5-Step Roof Restoration System
Step 1: Meticulous Inspection & Structural Repairs
Before any water touches your roof, we execute a complete structural audit.
For Tile Roofs: We identify and replace broken, cracked, or water-damaged tiles with matching profiles. We completely clean out failing mortar from ridges and hips.
For Metal Roofs: We check for structural rust, failing rubber washers, and loose roof screws, securing the metal sheets down tight.
Step 2: Industrial High-Pressure Deep Cleaning
Slapping paint over dirt guarantees peeling within 12 months. We use industrial-grade, high-pressure washers (operating up to 4000 PSI) to blast away decades of baked-on dirt, stubborn black fungal slime, moss, and lichen. We wrap around the entire gutter line, ensuring all heavy debris is completely cleared without flooding your ceiling cavities.
Step 3: Re-Bedding & Multi-Stage Pointing
(Tile Roofs) Where old mortar has crumbled, we re-bed the ridge caps securely. We then apply premium, flexible acrylic pointing compounds across all ridges and hips. Unlike old-school cement mortar, modern flexible pointing expands and contracts naturally with seasonal Macarthur temperature shifts, meaning it will never crack or blow out.
Step 4: Targeted Priming & Sealing Layers
Different roof materials require custom chemistry to ensure perfect paint adhesion:
Porous Concrete Tiles: We apply a heavy-build acrylic sealer to lock down the chalky surface and stop the topcoat from sucking into the tile.
Terracotta Tiles: Terracotta requires highly specialized glazed primers to bond with the slick surface.
Metal/Colorbond: We apply anti-corrosive, rust-inhibiting metal primers to protect raw edges and prevent future oxidation.
Step 5: Dual Coats of Premium Dulux Acratex Next Gen Membrane
Finally, we apply two heavy coats of Dulux Acratex Next Gen Roof Membrane. This isn't standard house paint; it is a specialised, ultra-thick, flexible coating engineered to withstand extreme weather, UV degradation, and pollution. It forms a durable protective shield that stays vibrant for years and is completely safe for collecting tank drinking water.
