Roofing Companies · New Zealand
Roofing
A roofing company with 5 crews based in Christchurch, serving the wider Christchurch area and focused on re-roofing, plus roof repairs and leaks. Before working with us, 69% of enquiries came through Builderscrack and similar paid platforms, where the same lead often went to three or four competitors. The goal was more exclusive inspection requests, a lower cost per contract and a pipeline the owner controls.

The challenge
Where the business was stuck
- Roof replacements are high-value but infrequent purchases, so buyers are cautious and compare several quotes.
- Storm and weather events create sudden demand spikes that most roofers aren't set up to capture.
- Roofing has a trust problem. Buyers worry about cowboys, so credibility signals matter more than in most trades.
- Peak season (repairs spike after storms; re-roofs are strongest from spring to autumn) was not being planned for, so budget ran out when demand was highest.
The approach
Two services, one goal
We focused on Lead Generation Program and Email Marketing, the two channels with the best cost per contract for roofing businesses in Christchurch. Every call, form and chat was tracked to a booked outcome from week one, so every decision was based on revenue, not clicks.
What we did
The technical work behind the numbers, service by service.
Service 1
Lead Generation Program
- Added the business to our exclusive lead generation program: one roofer per service area, so leads are never shared or resold.
- Launched dedicated lead capture pages and campaigns for re-roofing and roof repairs and leaks across 8 service areas in the wider Christchurch region.
- Qualified every lead by job type, location, budget and timeframe before delivery, with instant delivery by SMS and email.
- Replaced paid lead credits on Builderscrack with a fixed monthly program and weekly reports on cost per lead and booked jobs.
Service 2
Email Marketing
- Set up SPF, DKIM and DMARC on the sending domain and warmed it up, taking inbox placement from 75% to 99%.
- Segmented 4,900 past customers and quote recipients by job type, area and last service date.
- Built 5 automated flows: welcome, quote nurture, post-job review request, annual service reminder and win-back.
- Sent a monthly campaign with seasonal offers for re-roofing and related work, A/B testing subject lines and send times.
