Case Study

Case study: nearly doubling a roofer's leads after a slow summer

By Nico · 8 October 2026 · 4 min read

Growing your leads usually means paying more for each one. The more you push, the more expensive it gets. So when a roofing company’s leads nearly doubled in a month and the cost per lead went down, it’s worth explaining how.

The problem: a quiet summer

August was a quiet month for this roofing company in Surrey. During the heatwave, fewer homeowners were searching for roofing work, and the leads that did come in were expensive.

That’s normal for roofing. When the weather’s dry and hot, roofs aren’t top of anyone’s mind. When the weather turns, demand comes back quickly.

The goal: grow fast without costs rising

When demand picked up in September, the aim was simple: get as many extra leads as possible, without letting the cost per lead rise with them.

What I did

Looking back over the summer, one thing stood out. Roof repairs had been the most reliable source of cheap enquiries all season, even when everything else was quiet.

So the account was set up to:

  • Let the roof repairs campaign take more of the extra searches as demand came back, rather than spreading the budget evenly across everything
  • Adjust bids towards the devices and audiences that were converting best, so the extra spend went where it was most likely to bring in enquiries

In other words: when the searches came back, the budget went to the work that had already proven it could bring in leads cheaply.

The results

September compared with August:

August September Change
Leads 20 37 +85%
Roof repair leads 6 18 3×
Cost per lead – – −29%
Clicks that became enquiries 4.7% 7.3% +2.6 points

Leads nearly doubled, roof repair leads tripled, and each lead cost 29% less than in August.

Why it worked

  • Using the summer’s data. Even quiet months tell you something. August showed which campaign brought in the cheapest, most reliable leads.
  • Backing the winner. Instead of growing everything at once, the extra demand was channelled into what was already working.
  • Being ready for the change in season. When the searches came back, the account was set up to make the most of them straight away.

The takeaway for your business

Quiet months aren’t wasted months. They show you what’s really working, so you’re ready to grow when demand returns. If you’d like to read more on this, see should you run ads during your quiet season?
