Common Issues We Fix

  • At DNT Maintenance, we don’t simply patch cracked tiles — we replace them correctly to maintain the structural integrity and weatherproofing of your roof.

    Choosing the correct tile is critical. Every roof has specific tile profiles, thickness, and interlocking systems. Installing the wrong tile can create gaps, cause water penetration, affect roof alignment, and lead to long-term leaks and internal damage.

    Our process includes:

    • Careful removal of damaged tiles without disturbing surrounding tiles
    • Matching the exact tile profile, size, and material
    • Checking sarking and underlay condition
    • Securing tiles correctly to prevent movement
    • Inspecting surrounding ridge capping and mortar

    Proper tile replacement protects your roof from leaks, mould growth, timber rot, and structural issues — ensuring the long-term health of your roof.

  • At DNT Maintenance, we carefully assess the condition of your sheet metal roof(colorbond roofing) before recommending repair or full replacement. Rust can weaken the structural integrity of metal roofing and lead to leaks, corrosion spread, and internal water damage if not treated correctly.

    For minor surface rust, we:

    • Mechanically remove rust and corrosion
    • Treat the area with a rust converter and primer
    • Seal fasteners and joints
    • Apply high-quality protective coatings designed for Australian weather conditions

    For severely rusted or perforated sheets, we:

    • Remove and replace damaged roof sheets
    • Match the correct profile (Corrugated, Trimdek, Klip-Lok, etc.)
    • Replace rusted screws with weather-sealed roofing fasteners
    • Check insulation and roof battens
    • Reseal flashings and overlaps to ensure full waterproof protection

    Proper repair or replacement prevents leaks, structural deterioration, and costly internal damage. We focus on long-term durability — not temporary fixes — ensuring your metal roof remains strong, sealed, and weather-resistant.

  • Roof repointing (includes re-bedding or re-mortaring) restores the mortar joints between ridge, hip and tile beds, and between bricks or concrete tiles. Knowing whether you need repointing helps prevent water ingress, tile loss and structural damage. Check the following signs and steps to decide if repointing is required.

    Signs you may need roof repointing

    • Loose or missing mortar: Mortar that crumbles when touched, or gaps where mortar has fallen out.

    • Cracked or powdery mortar: Longitudinal cracks, hairline to wider cracks, or mortar that pulverises under light pressure.

    • Dislodged or loose tiles or ridge caps: If ridge tiles rock or tiles slip after wind or rain, the mortar bed may have failed.

    • Water leaks or damp patches: Water stains on ceilings, wall tops or under the roofline can indicate mortar failures allowing moisture through.

    • Vegetation growth: Moss, weeds or plants growing in mortar joints accelerate deterioration and show joints are compromised.

    • Excessive mortar loss at hips and ridges: These areas are most exposed; if mortar is missing or eroded there, repointing is often required.

    • Pointing inconsistent with roof age: If mortar appears much older or more eroded than the roof tiles, joints may need renewing even if tiles are intact.

    • Mortar recessed below tiles: When mortar sits well below the tile edge (recessed), it can’t support tiles properly and should be renewed.

    Assessment steps

    1. Visual inspection from ground level: Use binoculars to spot displaced ridge tiles, missing mortar and moss growth.

    2. Careful close inspection from safe access: Where safe to do so, inspect hips, ridges and tile beds for crumbly mortar and movement. Don’t climb unless qualified or using proper safety equipment.

    3. Check inside the roof space: From the ceiling or in the attic look for light through joints, damp, or water stains beneath mortar joints.

    4. Tap test: Gently tap ridge tiles—hollow sounds or movement may indicate loose bedding mortar.

    5. Age and previous repairs: Consider when the last pointing was done. Mortar typically lasts decades, but exposure and poor mixes reduce life.

    6. Professional roof inspection: If you’re unsure, have a licenced roofer or roofing contractor inspect the roof and advise on repointing vs other repairs.

    When repointing is necessary

    • If mortar is soft, crumbly or missing in several places, repointing is usually required to secure tiles and prevent leaks.

    • If only small isolated areas are affected, targeted patch re-pointing may be sufficient.

    • If the tile underlay, battens or tiles are also damaged, repointing alone may not solve the problem; broader roof repair or replacement could be needed.

    What repointing involves

    • Removing loose, damaged mortar to a suitable depth without damaging tiles.

    • Cleaning joints and ensuring mortar beds are sound.

    • Insert the correct and precise amount of mortar

    • Insert the correct and precise amount of flexible UV rated weatherproof repointing material

    • Full inspection of the work to ensure everything is sealed and correctly placed.
