The fastest quotes we turn around are the ones that arrive with everything we need the first time — no follow-up emails chasing a missing dimension or an unconfirmed compliance requirement. The slowest are the ones where a two-line enquiry ("need pricing on a roofing pack for a 2000m² shed") kicks off three or four rounds of back-and-forth before we can actually price it properly.
What a complete take-off submission includes
- Roof plan and elevations — even a rough architectural or structural drawing is far better than a verbal description; dimensions, pitch and roof plane count all affect material quantities and flashing detail.
- Roof area and pitch — if drawings aren't available, at minimum confirm total roof area and pitch so blanket, sheet and sarking quantities can be estimated accurately.
- Purlin/rafter spacing — affects batten, spacer system and safety mesh specification; even an approximate figure helps narrow the right product range.
- Building classification and use — occupied vs unoccupied space changes insulation and acoustic requirements significantly.
- Compliance drivers — BAL rating if bushfire-prone, any acoustic Rw targets, NCC climate zone, and any fire engineering requirements known at enquiry stage.
- Program and delivery timing — staged delivery needs for multi-building or multi-stage programs, and any hard delivery dates driving the quote.
Why this avoids re-quotes later
Compliance requirements that surface after an initial quote — a BAL rating confirmed later, an acoustic report landing after pricing — almost always change the material spec, which means the original quote needs revising anyway. Getting these confirmed upfront, even as a "best current understanding, to be confirmed," lets us flag likely cost impact early rather than surprising the builder with a price change once the requirement is formalised.
The take-offs that turn around fastest aren't necessarily the simplest jobs — they're the ones where the estimator sent drawings and a written scope together, so there's no ambiguity about what's actually being priced.
Drawings plus scope, not one or the other
A drawing without a written scope leaves compliance drivers, program timing and delivery preferences unstated. A written scope without drawings leaves dimensions and roof geometry to assumption. Sending both together is what actually produces a fast, accurate quote — each fills the gaps the other leaves open.
For multi-stage and program supply jobs
If the job involves staged delivery across multiple buildings or construction phases, include the staging sequence and rough timing alongside the take-off. This affects not just quantity planning but delivery scheduling — see our guide on staged delivery for large roofing programs for more detail on how PREZO structures multi-stage supply.
A quick pre-submission checklist
- Roof plan/drawings attached (even rough)
- Total roof area and pitch confirmed
- Purlin/rafter spacing noted
- Building use and any known compliance drivers (BAL, acoustic, NCC zone)
- Delivery program and staging requirements
Send your take-off with these details and we'll turn around a properly scoped quote — not a rough estimate that needs revisiting once the real requirements surface.
