Roofing disputes and metal wall cladding disputes generally arise out of poor contractual documentation and/or defective work and/or materials.

Plans often lack critical detail as to flashings, gutters, penetrations etc and specifications are often general and not project specific. Quotations will often omit (deliberately or accidentally) items of work but not expressly state so on their face, and may contain estimates for the works to be undertaken in the form of PC (Prime Cost) or Provisional Sums that are woefully inaccurate for the works that are in fact required to be undertaken/supplied.

Many building projects are not well programmed or coordinated and roofing works are in fact time critical in terms of holding costs for scaffolding and delay to other trades that require protection from the weather such as interior linings. In addition, owners and head contractors will often request changes/variations to the scope of work and specification as work progresses and no price will be agreed in advance.

On the other hand, mistakes and errors are a feature of any building related work and some roofing contractors lack the necessary skills and/or fail to have adequate quality assurance processes in place to ensure they achieve the agreed/specified scope of work to the specified standard, and/or to complete their work by the due date for completion.

In the circumstances, it is little wonder that roofing disputes arise from time to time. There are essentially two types of disputes that we deal with:

  • technical (in the legal sense) disputes – ie disputes that arise out of non-compliance with the technical requirements for making and responding to payment claims under the Construction Contracts Act 2002 (the Act); and
  • merits based disputes – ie disputes about the merits of the parties’ arguments in terms of the construction contract that governs their relationship, or in the case of a contract with a residential occupier, the statutory warranties that are implied into every residential building contract under s362I of the Building Act regardless of whether there is a written building contract. Typical merits based plumbing disputes include disputes in relation to:
    • non-payment for work undertaken;
    • contract interpretation – what the parties actually agreed;
    • scope of work;
    • quality of work;
    • quality of materials;
    • time for completion;
    • payment – the value of the work undertaken in the absence of express agreement as to price;
    • estimates v actual cost;
    • variations – whether certain work is in fact a variation to the agreed scope of work and the value of that varied work;
    • defective work;
    • scope and cost of rectification work;
    • repudiation/cancellation of the contract; and
    • damages for breach of contract.
