EXAMPLE AT A GLANCE
This fictional Liverpool pitched roof vent installation project has 7 itemised lines and an illustrative £1,824.00 total. The app-exported PDF, first-page preview, measurement basis, scope boundaries and matching UK estimating guide let you inspect every quantity and rate.
What this example covers
This fictional job is set in Liverpool and concerns two roof ventilation points. Install two selected roof ventilation terminals through a sound existing roof covering, with compatible flashings and interior duct connection allowance. The estimate is a bounded document: the customer should be able to compare the described work with its measured lines, product allowances and exclusions. The matching UK guide explains how to prepare those inputs.

Itemised pitched roof vent installation example
These 7 lines reproduce the app-exported PDF exactly. The largest is Terminal fitting at £416.00; this is one fictional component, not a typical price. Read each quantity with its unit: area, length, time, count and lump sum describe different work and must not be interchanged.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Vent location survey | 1 lump sum | £168.00 | £168.00 |
| Roof access and protection | 1 lump sum | £256.00 | £256.00 |
| Roof opening preparation | 2 each | £132.00 | £264.00 |
| Vent terminal allowance | 2 each | £176.00 | £352.00 |
| Flashing kit allowance | 2 each | £76.00 | £152.00 |
| Terminal fitting | 2 each | £208.00 | £416.00 |
| Duct connection and check | 2 each | £108.00 | £216.00 |
| Illustrative total | £1,824.00 | ||
The table separates the named product or material allowances from labour and site tasks wherever the scope needs that distinction. Before replacing a rate, check whether the product allowance includes delivery, waste, fixings and the selected specification.
How the total is calculated
Roof opening preparation is 2 each × £132.00 = £264.00. Vent terminal allowance is 2 each × £176.00 = £352.00. The other lines follow the same calculation and sum to £1,824.00. Each fixture line lands on an exact penny, so the native PDF total equals the sum of the displayed line amounts.
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 0% tax field and zero markup are example document inputs, not an instruction for a live quote. Decide the correct settings for your own business and job.
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, explicit revised allowance or separately agreed task. Keep the customer informed of which figure changed and why before producing another PDF.
