    Common Mistakes

    Common errors to avoid in your coursework

    • Neglecting to inspect the roof structure (battens, underfelt) for hidden damage before installing new slates or tiles, leading to premature failure.
    • Using incompatible fixings (e.g., nails instead of clips) for certain tile types, which can cause tiles to dislodge under wind uplift.
    • Incorrectly calculating head lap when replacing slates, resulting in inadequate weatherproofing and potential leaks.
    • Failing to mix old and new tiles gradually across the roof when patching, creating a visually jarring repair that does not meet aesthetic specifications.
    • Students often fail to inspect the roof substrate for rot or damage before laying new slates/tiles, leading to premature failure.
    • A common error is mixing incompatible slate or tile profiles from different batches, resulting in uneven lay patterns and potential leaks.
    • Many learners overlook the requirement to protect adjacent surfaces (e.g., gutters, glazing) from falling debris, causing unintended damage to surrounding areas.
    • Confusing reclaimed tiles with new ones that may not match in profile or colour, leading to visual inconsistencies.
    • Over-nailing or under-nailing slates/tiles, causing breakage or insecure fixings.
    • Neglecting to check and replace degraded underlay or battens before reinstating the roof covering.
    • Failing to set up fall protection or access towers correctly, often due to rushing or underestimating risks.
    • Misinterpreting roof pitch and headlap requirements, resulting in inadequate weather resistance.
    • Failing to verify the cause of leaks before replacement, leading to recurrent issues.
    • Using incorrect nail types or fixings that corrode or fail under load.
    • Neglecting to inspect and prepare the roof substrate before installing new slates/tiles.
    • Overlooking fall protection measures when working on fragile roof structures.
    • Misinterpreting the contract specification, resulting in non-compliant materials or finishes.
    • Failing to inspect the roof structure for underlying defects before replacing coverings, leading to recurrent issues.
    • Mismatching slate or tile sizes and thicknesses causing uneven roof planes and potential leaks.
    • Neglecting to check and comply with specific contract requirements regarding material provenance or disposal methods.
    • Underestimating the time required for safe setup of access equipment, leading to rushed work and safety risks.
    • Failing to inspect and repair substrate rot before re-covering.
