6 In the Points of Claim the Body Corporate is not a party. The Points of Claim also omit the roof in the description of the common property. Nevertheless in answer to a question from me, Mr Brahe stated that the roof is part of the common property and I treat it as such. From a practical point of view it is accepted that the owner of the roof is at least one of the Applicants and that any loss has been suffered by one or more of them.
7 The building was constructed by the Respondent pursuant to a building permit granted to him on 30 June 1993. A certificate of Occupancy was issued on 12 June 1996.
8 The exact arrangement regarding the construction of the premises was unclear, but it appears that the Respondent entered an agreement with Mr and Mrs Reid, who owned a substantial block of land, including the land upon which the premises is built. The Respondent's evidence is accepted that the Reids were to supply the land and he was to finance and build five quality dwellings. The Reids would receive one and he would be entitled to the proceeds of sale of the remaining four, which included the premises. His evidence is also accepted that the five dwellings were designed by the architect Nicholas Day.
9 Neither the Applicants nor the Respondent provided copies of the drawings or specifications for the premises to enable a determination of whether construction was faithful to the design, however the Respondent said that he built in accordance with the plans and specification provided by Mr Day. The Respondent said that he no longer has the drawings. I have no reason to doubt the accuracy of his statements.
10 The roof as originally built was (and remains) at a pitch of 30o. The original roof was clad in "plain tiles" underlaid by Sisilation sarking. "Sisilation" is the brand name of aluminium-coated paper-based insulation sheet which also acts as a moisture barrier in roofs and walls.
11 Plain tiles are fired clay tiles, approximately 260mm long by 165mm wide and 10 mm thick. There is a nib along the length of one end, making the tile at that point 25mm thick. The purpose of the nib is to hook over the roof battens, and thereby attach the tiles to the roof. When laid, the tiles overlap so that, with the possible exception of edges and penetrations, there is no point on the roof where there are less than two layers of tiles and for a substantial proportion of the roof there are three layers.
12 The Applicants alleged that from at least the date Mr and Mrs Thurston moved into their apartment the roof has not been water-tight and has leaked continually, and has damaged 3 Drake Street in particular. They said that Mrs Thurston and her late husband "constantly complained" to the Respondent that the roof was not water-tight and that damage was being caused to 3 Drake Street and to the common property. Mr Brahe gave uncontradicted evidence that the first he and his wife knew of the water ingress problem was the first time it rained after they moved into their new home.
13 The Applicants alleged that the Respondent agreed to rectify the problem on numerous occasions and attempted to do so himself, or by agents, culminating in the appointment by the Respondent of Tre Tempo Project Consultants in 2005. They said Tre Tempo ascertained that the roof tiling would need to be re-laid and that the sarking had been shredded, but the Respondent withdrew instructions for Tre Tempo to undertake the works. Mr McMurray, formerly of Tre Tempo, gave evidence for the Applicants.
14 Instead, the Applicants alleged, the Respondent had scaffolding erected in April 2005 (and left it in place until August 2005), a small number of replacement tiles were delivered to site but were not used and work was undertaken by two workmen for about a day and a half, but it did not fix the leaks. The Applicants said they advised the Respondent that they would seek quotes and have the work done by another roofer, and seek recompense from the Respondent. They alleged they obtained advice from two roofing contractors that the roof was not water-tight and quotations were obtained, the lowest of which was from Mr Shane Jones.
15 In contrast, the Respondent alleged there had been minimal leaking around a sky-light, which was rectified from inside the roof by George Smith Roofing and that no complaint was "formally" received from Mr and Mrs Thurston. He said there was only one isolated area of sarking which was torn and this was replaced by George Smith Roofing during the course of construction. The Respondent said that Tre Tempo did not undertake further works and replacement roof tiles were not laid because Mr Brahe refused access to the site.
16 The Respondent alleged that any leakage to the front entrance area, which is part of the common property, was caused by the installation of air-conditioning by "the Applicant's contractor ... which required holes to be drilled through the roof for the compressors."
17 The parties agree that Mr Jones undertook roofing work, for which he was paid $28,750.00; half by Mrs Thurston and half by Mr and Mrs Brahe. The roofing work undertaken by Mr Jones was replacement of the plain tiles with Swiss Patterned tiles - a shape that calls for less layers of tiles to achieve a water-tight roof, as it is specifically designed to exclude wind-driven rain. The work was undertaken in or about August 2005.
18 The Applicants alleged there was water damage to the interior of Mrs Thurston's property, which cost her $3,520.00 (inclusive of GST) to rectify. The Respondent denied this in his pleadings but did not provide evidence to contradict it. In contrast, Mrs Thurston gave evidence that she had incurred this cost by reason of water ingress and her evidence is accepted.
