Early project budgeting
Get a broad roofing allowance when the design or measurements are still incomplete.
Independent New Zealand roofing platform
New Zealand roofing answers, pricing and tools in one place.
Research a product, estimate a roof with or without measurements, check published pricing, use detailed takeoff tools or ask RoofHub a question.
No measurements required to start NZ source-backed evidence Simple through to detailed tools
Independent evidenceSources, dates, GST basis and scope stay visible.
Deterministic pricingRoofHub software calculates project ranges. AI does not invent prices.
Ask RoofHub anywhereGet help with a page, a tool step or a roofing question without starting over.
Start where you are
Simple when you need simple. Detailed when you need detailed.
RoofHub is useful whether you know almost nothing about the roof or already have a complete set of quantities.
Estimate a roof
Start with approximate shape, size and pitch. You do not need measurements, and you can refine the same project later.
Start a quick estimateCompare roofing systems
Understand corrugate, five-rib, pressed metal tile and architectural tray using NZ product and market evidence.
Compare roof systemsUse measurements
Already have quantities or plans? Move straight into the detailed estimator and build a measured low/high allowance.
Open detailed estimatorCheck a roofing quote
Already have a written price? Compare GST, product and scope against the same RoofHub project before judging the headline total.
Check a quoteOne platform, different jobs
Useful whether you are researching, budgeting, measuring or pricing.
You do not need to choose a user type first. Start with the task, then add detail only when it improves the answer.
Measured estimating
Use actual roof areas, ridges, hips, valleys and other components when you need more control.
Product decisions
Compare profiles, pitch requirements, pricing evidence and practical trade-offs before specifying a system.
Quote context
Understand what a roofing quote should include and why two legitimate quotes can differ materially.
Questions New Zealanders are asking
Useful answers first. A tool when it helps.
Research the issue, see what the evidence actually says, then apply it to a project without re-entering everything.
Quotes and decisions
How to compare roofing quotes in New Zealand
Compare NZ roofing quotes on the same GST basis and scope, check products, access, removal, flashings and exclusions, and understand when two prices are not directly comparable.
Read the answer →PricingNew roof cost NZ: what should a new-build roof budget include?
Plan a new-build roof budget in NZ without mixing in reroof removal costs. Compare roof area, profile, geometry, access, flashings, underlay, rainwater scope and current source-specific price guides.
Read the answer →ComparisonsCorrugated vs five-rib roofing: what changes the choice?
Compare NZ corrugated and five-rib roof profiles, minimum pitches, cover widths, installation scope and material pricing without confusing profile with coating.
Read the answer →GuidesHow long does a metal roof last in New Zealand?
Understand the difference between roof lifespan, product warranty and Building Code durability, with maintenance and reroof decision questions for NZ homes.
Read the answer →ComparisonsCOLORSTEEL vs ZINCALUME: what are you comparing?
Compare current NZ COLORSTEEL and ZINCALUME terminology, coatings, site exposure and roof specifications, including changes to products since 2025.

Understand NZ membrane roofing systems including TPO, EPDM/butyl, torch-on bitumen and liquid membranes, with design, substrate, drainage, appraisal and quote-check questions.
Read the answer →The RoofHub method
Market evidence and estimating logic stay separate.
Supplier prices, manufacturer specifications, published project examples and technical guidance provide useful evidence. RoofHub keeps that evidence traceable, then uses an explicitly versioned estimator model when calculating a project.
How RoofHub handles evidence- 01Research
Record the source, date, region, units, GST status and what a published number actually covers.
- 02Separate
Keep market observations distinct from RoofHub's approved estimator rates and assumptions.
- 03Calculate
Turn approximate or measured roof quantities into a transparent low/high project range.
- 04Refine
Replace assumptions with real measurements or site information without restarting the project.
Advanced tools
Already have measurements or plans?
Move straight into the detailed RoofHub estimator. Enter roof area plus ridges, hips, valleys, barges, rainwater items and custom components, then refine the same project as better information becomes available.
