EXAMPLE AT A GLANCE
This fictional Canberra, Australian Capital Territory pitched roof vent installation example contains 7 itemised costs totalling A$2,975.43. Its app-exported PDF uses the exact metric quantities and AUD rates in the table, with scope assumptions and exclusions explained below.
Project scope: Two roof ventilation points
Install two selected roof ventilation terminals through a sound existing roof covering, with compatible flashings and interior duct connection allowance.
This original fictional example is set in Canberra, Australian Capital Territory. Harbour & Gum Projects and Alex Morgan are made-up parties. The matching Australian guide explains which measurements, product decisions and site conditions turn this brief into a client-ready quote.

Itemised pitched roof vent installation costs
These 7 AUD lines reproduce the native app export. Roof opening preparation is measured as 2 each; Vent terminal allowance uses 2 each. Some lines are measured work while others are a product or site-task allowance. Read the unit before reusing the structure for a different job.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Vent location survey | 1 job | A$274.05 | A$274.05 |
| Roof access and protection | 1 job | A$417.60 | A$417.60 |
| Roof opening preparation | 2 each | A$215.33 | A$430.66 |
| Vent terminal allowance | 2 each | A$287.10 | A$574.20 |
| Flashing kit allowance | 2 each | A$123.98 | A$247.96 |
| Terminal fitting | 2 each | A$339.30 | A$678.60 |
| Duct connection and check | 2 each | A$176.18 | A$352.36 |
| Illustrative total | A$2,975.43 | ||
Product selection and installation should be clear from the descriptions. Confirm delivery, fixings, preparation, waste and any specialist trade responsibility for the actual job rather than assuming each allowance covers them.
Check the arithmetic
Roof opening preparation: 2 each × A$215.33 = A$430.66. Vent terminal allowance: 2 each × A$287.10 = A$574.20. All other lines use the same quantity-by-rate calculation and sum to A$2,975.43. Every fixture line lands on an exact cent, so the native PDF subtotal equals the displayed table total.
Measurement to check: Record roof pitch, covering type, terminal position and duct run for each vent. Selection to check: Keep terminal, flashing and duct connector allowances distinct. The PDF uses a 0% tax input only to make its fictional arithmetic visible. Confirm the GST treatment that applies to the actual job and set your own markup before sharing a client quote.
Assumptions and exclusions
Confirm a clear route and safe access before opening the roof.
Outside this stated scope: No whole-roof ventilation design, new fan or roof deck repair.
Hidden framing conflict or an unsuitable duct route changes placement. A changed condition should lead to a newly measured quantity, revised allowance or separately agreed task. Keep the client informed of the changed figure before producing another PDF.
