• Input benchmark – roof tiling

    These input benchmarks have been developed in consultation with the Roofing Tile Association of Australia.

    They represent the industry norm and apply to roof tilers who work directly with household customers and are responsible for purchasing their own materials. The main activity for these businesses is the installation of ceramic or concrete tiles, slate or shingles.

    These benchmarks are current as at April 2015.

    Input benchmark guide

    The table below sets out input benchmarks for roof tilers.

    Input benchmark examples

    Example 1

    Richard runs a roof tiling business with one regular sub-contractor to assist him during busy periods. They work only on household jobs, supplying and installing concrete and terracotta tiles.

    On average, they install 60 square metres per day. Richard charges an average price of $60 per square metre plus 10% for materials.

    Richard's records show that he has purchased 70,000 concrete and 90,000 terracotta tiles during the year. Using the benchmarks, he estimates that he has tiled a total of 13,720 square metres with income of $905,520.

    Richard's records show reported income of $900,000. This is within the benchmarks and accounts for discounts offered to friends. He is happy with his record keeping.

    Example 2

    Peter runs a roof tiling business with one tradesman. He installs terracotta tiling only.

    Over the year they have averaged an installation rate of 50 square metres per day and charged an average of $60 per square metre.

    Based on statements from his supplier, Peter has purchased 160,000 terracotta tiles in the year. Using the benchmarks, he estimates that he has tiled 12,307 square metres during the year with income of $812,262 (including 10% for materials).

    Peter's records show income of $750,000 for the year, which is less than expected. He reviews his quote book and finds several jobs where he received cash payment and used the quote as a tax invoice. This is an additional $60,000 income.

    Peter recalculates his income for the year as $810,000, which is within the benchmarks. Peter asks his bookkeeper for advice on keeping better records.

    Example 3

    Rodney runs a roof tiling business and works only on household jobs.

    Rodney has purchased $330,000 worth of roof tiles according to his supplier statement for the year.

    Using the benchmark of 40% for cost of tiles as a percentage of the price charged to the customer, Rodney calculates his sales should be approximately $825,000.

    As he has only recorded $700,000 sales, he decides to review his records and speak to his bookkeeper.
