Common questions
What others asks before signing up?
How much does it cost to replace a roof in Australia?
A full roof replacement runs from about $10,000 for a small single-storey home to $40,000+ for a large two-storey property, depending on material, roof area, access and whether asbestos is involved. This calculator gives you an instant estimate for your exact roof in under a minute.
How much does Colorbond vs tile roofing cost per square metre?
Installed, concrete tile runs about $40–$80 per m², Colorbond steel $50–$90 per m², and terracotta tile $80–$200 per m². The calculator applies Australian per-m² rates to your roof area and adds removal, access and add-ons.
How accurate is this roofing calculator?
It gives a realistic estimate based on current Australian per-m² rates, material, access and asbestos handling. Your roofer confirms the final price after a site measure and inspection.
Does the estimate cover asbestos roof removal?
Yes. If you select an asbestos (fibro) roof, the calculator adds a licensed-removal cost. Asbestos must be removed by a licensed removalist, and the final figure is confirmed after a licensed inspection.
Can I add this calculator to my website?
Yes — embed it on WordPress, Webflow, Squarespace, Wix or Shopify with a single snippet, or share your free hosted Leadkit estimate page if you don't have a site.
What do I get when someone uses my calculator?
You get the homeowner's name, phone, email and full roof scope, plus a branded PDF estimate — a qualified lead you can call back the same day instead of driving out to quote for free.
Is Leadkit really free?
Yes. Free lets you add up to 3 calculators to your website and receive 10 leads per month — no credit card. Every lead beyond the cap is still captured and held for you; upgrading to Pro ($29/mo) opens them all retroactively and removes the cap.
Do I need to know how to code?
No. You get an embed code (one line of HTML). Paste it into your website builder — Wix, Squarespace, WordPress, or any custom site. That's it.
How accurate are the price estimates?
You configure the calculator formulas to match your actual pricing. Leadkit provides the framework; you set the numbers. Estimates can be as detailed or as rough as you like.
What happens with lead data?
All lead data is stored securely in your workspace. You own it. We never sell or share your leads with anyone.
Can I use Leadkit as an agency for multiple clients?
Yes — our Agency plan lets you create and manage separate workspaces for each of your clients, all from one dashboard.
What's the difference between the plans?
Free: up to 3 calculators, 10 leads/month (over-cap leads held + locked until upgrade). Pro: unlimited leads, unlimited calculators, white-label, branded email sending, analytics, email templates. Agency: everything in Pro plus multi-workspace management.

How it works
How this roofing estimate is calculated
This calculator produces an estimate, not a binding quote. It applies Australian per-m² roofing rates to your roof area and material, then adjusts for access, asbestos and add-ons.
GST handling: All estimates are GST-inclusive at the Australian rate of 10%.
1
Measure the roof
Enter your roof area in m² — roughly your home's floor area times 1.2 for a pitched roof.
roof_area (m²)
2
Price the material
Each material has its own per-m² installed rate, plus a per-m² cost to strip and dispose of the old roof.
new = roof_area × material_rate
3
Adjust for access & asbestos
Steep or two-storey roofs add an access loading and scaffold; asbestos roofs add a licensed-removal cost with a minimum charge.
asbestos = max(roof_area × rate, minimum)
4
Add extras & GST
Gutters, skylights and underlay are added, then 10% GST is applied to reach the total.
Real ranges from Australian roofing cost guides. Your actual price depends on roof area, access, asbestos and material choice.
