Input benchmark – roof painting and repair

Businesses in this industry repair and restore existing roofing materials. The major products and services provided include replacing broken tiles, securing flashings, repairing capping with cement or acrylic mortar, cleaning roof tiles and painting roof sealer.

You may find the input benchmarks useful in calculating the expected income based on the labour and materials used. They apply to roof painters and repairers who work directly with household customers and who are responsible for purchasing their own materials.

The input benchmarks have been developed in consultation with the Master Painters Association of Australia, various state roof tiling associations and industry participants.

They represent the industry norm. You should consider your own personal circumstances when using the input benchmarks to assess your situation.

These benchmarks are current as at April 2015.

Input benchmark examples

Example 1

Rob operates a roof painting business and has one sub-contractor working for him. They work on household jobs only.

Rob establishes from his quote book that his average job size is about 180 square metres and they normally take between 2 to 3 days to complete. He normally charges about $3,500 for each job.

Rob reviews the statements from his supplier and finds that he has purchased 1,620 litres of sealer, which covers approximately 16,200 square metres of roof painting. Using his average job size of 180 square metres, Rob calculates that he completed about 90 jobs during the year for income of $315,000.

Rob's records show reported income of $320,000, which is within the benchmarks and close to his estimate. He is happy with his record keeping.

Example 2

Tony has a specialist roof painting business with one employee. His work is household roof painting only and he does not perform repair work.

Checking his business records for the year Tony finds he has income of $225,000 for 90 jobs. Tony normally charges $2,500 for an average house that is painted in two days.

Using the benchmark guide, Tony estimates he would have worked 180 days to earn $225,000. However, Tony has had a busy year and is sure he worked more than that.

Tony reviews his quote books and finds 20 jobs where he was paid cash that was not deposited to his bank account. He charged $45,000 in total for these jobs. Tony recalculates his income for the year to $270,000 and is now within the benchmarks. Tony asks his bookkeeper for advice on keeping better records.
