Colorado contractors ask us two questions about Google Ads more than any others: “How much does it actually cost?” and “Does it actually work?” The honest answers are: it depends on your trade and your market — and yes, when it’s set up correctly, it works very well. Here’s what the real numbers look like.
We manage Google Ads campaigns for contractors across Colorado — roofers, remodelers, HVAC companies, plumbers, landscapers, fencing contractors, and more. The data we see across those accounts tells a consistent story: Google Ads is one of the highest-ROI marketing channels available to a contractor, and it’s also one of the most commonly mismanaged. Businesses that run it well see transformative returns. Businesses that set it up once and leave it running waste significant budget with little to show for it.
This post breaks down real benchmarks, explains the ROI math, and shows you exactly what separates campaigns that generate consistent leads from ones that drain your budget.
These benchmarks come from our own client data and industry aggregates for the Colorado market. Every trade is different — roofing and HVAC have higher average job values and higher cost-per-click, while landscaping and cleaning tend to have lower CPCs but higher volume needs. Use these as a realistic starting framework, not a guarantee.
The key insight: Even in a trade with a $100 cost-per-lead like roofing, a single closed job worth $15,000 from one Google Ads lead generates a 150x return on that lead cost. The math on well-managed Google Ads for contractors is almost always compelling — the problem is that most campaigns aren’t well managed.
Return on ad spend isn’t complicated, but most contractors we talk to have never run the numbers. Here’s a simple framework using a real-world example from our client base:
Close 25% of leads at an average job value of $12,000 = $93,000 revenue from $2,000 spent
That’s a 46x return on ad spend in a single month. Not every contractor will hit those numbers — close rates, average job values, and lead quality all vary — but the underlying math illustrates why Google Ads, when managed properly, is one of the most asymmetric investments available to a home service business. You’re spending dollars to generate leads worth thousands.
If the ROI math is so compelling, why do so many contractors tell us their Google Ads “didn’t work”? Almost always, it comes down to one of these five problems.
Setting up campaigns to target broad terms like “contractor” or “home improvement” burns budget on irrelevant clicks. A roofing contractor paying $8 per click for someone searching “roofing nails at Home Depot” is not getting ROI. Tight, high-intent keyword lists — “roof replacement Colorado Springs” — are what generate real leads.
Google Ads traffic sent to a generic homepage converts far worse than traffic sent to a dedicated landing page built specifically for that ad. If someone clicks an ad for “bathroom remodel Castle Rock” and lands on your homepage, most of them leave. A landing page that mirrors the ad, shows your work, and has one clear CTA converts 3–5x better.
If you can’t see which keywords generated phone calls and form fills, you can’t optimize. You end up pausing things that are working and keeping things that aren’t. Proper conversion tracking — including call tracking — is the foundation of any campaign that improves over time.
Google Ads campaigns need active weekly management: adding negative keywords to block irrelevant searches, adjusting bids by device and time of day, pausing underperforming ad variations, and expanding on what’s working. A campaign that hasn’t been touched in 60 days is almost certainly wasting a meaningful percentage of its budget.
Many contractors run ads targeting all of Colorado, or even nationally, when their service area is actually a 30-mile radius. Every click from outside your service area is money burned. Setting tight geographic targeting — specific cities, zip codes, or radius targeting around your location — is one of the simplest ways to immediately improve ROI.
“Google Ads isn’t a vending machine. It’s more like a garden — the returns compound with consistent attention, and neglect shows up in the numbers faster than almost any other channel.”
Here’s what we do differently for the contractor campaigns in our portfolio that consistently produce strong returns:
When Easy Home Construction came to Mountain Peak with zero paid advertising history, we built their Google Ads campaign from the ground up using this exact framework: tight keyword targeting, dedicated landing pages, full conversion tracking, and weekly optimization. The campaign reached a profitable cost-per-lead within 60 days and has maintained a consistent positive return since launch.
Google Ads makes the most sense for contractors when three conditions are in place: your average job value is high enough to make the math work (generally $500+ per job at minimum, with most contractor trades comfortably above this), your website and landing pages are ready to convert the traffic you’re paying for, and you have a system in place to respond to leads quickly. A lead that doesn’t get a callback within an hour has a dramatically lower close rate than one that does.
If those conditions are in place — or you’re ready to get them in place — Google Ads is one of the most reliable lead generation channels available to a Colorado contractor. The businesses in your market that are staying consistently busy year-round almost certainly have it running in the background.
We’ll audit your current setup (or build you a projection from scratch), show you realistic cost-per-lead benchmarks for your trade and service area, and give you a clear picture of what a well-run campaign should produce.
