How Much Should Roofers Actually Spend on Google Ads?

Every roofer we talk to asks the same question first: "How much do I need to spend?" And every agency gives the same useless answer: "It depends." That's technically true, but it isn't helpful. Here's the real math.

The short answer

Most roofing companies running paid Google Ads campaigns spend between $2,000 and $10,000 per month in ad spend, not including management fees. Where you land on that spectrum depends on four things:

• How many leads you can actually handle without dropping response time below 5 minutes
• Your average job value (repair vs. replacement vs. insurance restoration)
• How competitive your service area is — urban Florida is a different game than rural Midwest
• Whether you have sales process and follow-up dialed in, or still winging it

Budget tiers, and what each one realistically gets you

$1,500–$2,500/mo: Starter

This budget works if you're a smaller operation, have a tight service area (single metro or county), and are disciplined about following up fast. Expect 10–25 qualified leads per month in most markets, with cost-per-lead in the $70–$150 range for repair/inspection queries.

At this level, you should be running Google Search only, with one or two tight campaigns focused on the highest-intent keywords in your service radius. Don't spread to Meta, YouTube, or display — you don't have the budget to optimize multiple channels.

$3,000–$5,000/mo: Growth

The sweet spot for most established roofers doing a mix of insurance and retail work. At this level you should be running Google Search, Local Service Ads (LSAs), and some Meta retargeting. Expect 30–70 qualified leads per month, blended CPL in the $60–$130 range.

This is also the budget where weather-responsive scaling starts paying off — when a storm hits, you can push an extra $1,500–$2,000 in a single week and capture 20+ insurance claim leads.

$6,000–$10,000+/mo: Scale

Multi-market roofers, high-volume insurance restoration companies, and storm chasers. At this level you're running the full stack: Search, LSAs, Meta prospecting, Meta retargeting, YouTube trust-building, and dedicated landing pages per service and per city. Expect 80–200+ leads/month, with blended CPL often dropping to $50–$100 as Meta and LSAs scale.

The math you should actually care about

Cost-per-lead is a vanity metric. What matters is cost-per-booked-job, and the formula is:

Ad spend ÷ booked jobs = true customer acquisition cost

If you're spending $3,000/mo and booking 6 jobs from it, your CAC is $500. On a $10,000 average replacement job with 25% margin ($2,500), your ROI is 5x. That's a winning channel. If you're spending $3,000/mo and only booking 2 jobs, your CAC is $1,500, and you need to fix the leak in your funnel before adding more spend.

The leaky bucket principle

Before increasing ad spend, ask: is your sales process actually converting the leads you already have? Most roofers we work with are losing 40–60% of leads to slow response time and weak follow-up. That's $2 of leaks for every $1 of new spend. Fix that first.

What about management fees?

Competent paid ad management for roofing runs between $1,000 and $3,500/mo depending on scope (channels managed, creative produced, landing pages maintained). Add that to your ad spend for your true all-in cost.

Rule of thumb for total monthly investment:

• Starter: $2,500–$4,000/mo all-in
• Growth: $4,500–$7,500/mo all-in
• Scale: $8,000–$15,000+/mo all-in

Bottom line

Don't ask how much you should spend. Ask: "How many jobs do I want to book, and what's my max CAC?" Work backward from there. If you want 10 new jobs at a $500 CAC, you need to spend $5,000 in ads. Everything else is noise.
