How much should a home-service company spend on ads in 2026?
A practical framework for setting a roofing, HVAC, or plumbing marketing budget — based on revenue, job value, and cost per acquired customer, not guesswork.
The honest answer to "how much should I spend on ads" is: enough to win profitable jobs, and not a dollar more on channels that don't. That sounds evasive, so this guide turns it into a number you can actually set this week.
Start from revenue, not from a competitor's budget
A common rule of thumb across home services is to reinvest roughly 5–10% of revenue into marketing. A newer company fighting for visibility usually sits at the higher end; an established brand with strong word-of-mouth can sit lower. If you did $1.2M last year, that's a $60k–$120k annual marketing envelope, or roughly $5k–$10k a month across everything — ads, your website, call tracking, and the people running it.
That percentage is a sanity check, not a strategy. The number that actually matters is what it costs you to acquire one paying customer.
The only equation that matters: CAC vs. job value
Customer acquisition cost (CAC) is total marketing spend divided by the number of customers it produced. Compare it to the profit on an average job — not the revenue.
- Take your average job value. Say a roofing job is $12,000 with a 30% gross margin = $3,600 gross profit.
- Decide what fraction of that profit you'll pay to win the job. Most contractors are comfortable spending 10–20% of gross profit on acquisition.
- That gives you a target CAC. At 15% of $3,600, you can profitably pay up to ~$540 to land a roofing customer.
Now you can judge any channel honestly. If Google Local Services Ads bring you a customer for $300, scale it. If a lead-resale site costs you $450 in shared leads that close at 1-in-5, your real CAC is $2,250 — and you should walk away.
Where the budget should go
For most roofing, HVAC, and plumbing companies, the highest-intent spend is on people actively searching for a service right now:
- Google Local Services Ads (LSA) — pay-per-lead, shows the green "Google Guaranteed" badge, sits above search ads. Usually the best first dollar in home services.
- Google Search Ads — captures "emergency plumber near me" intent LSA doesn't fully cover.
- Google Business Profile + local SEO — the compounding asset. Slower, but it lowers your paid CAC over time.
- Retargeting — cheap insurance so the people who visited your site don't forget you.
Notice what's not at the top: brand awareness campaigns, billboards, and shared-lead marketplaces. Those can have a place once the high-intent channels are saturated — not before.
Don't let the platform mark up your spend
One quiet budget killer is the agency markup. Some agencies bill your ad spend through their own account and add a margin, so you never see the real cost-per-click. At Proforged you pay Google and Meta directly — we never touch or mark up your ad spend — so your CAC math stays honest. That's the whole point of the equation above.
A simple starting point
If you're not sure where to begin: set your monthly budget at the lower bound of 5–10% of revenue, put 60–70% of it into Google LSA and Search, 20% into your Business Profile and local SEO, and hold 10% for retargeting. Then watch CAC by channel for 60 days and move money toward whatever beats your target.

Retargeting for contractors: the second shot at the 95% who left your site without calling
Most homeowners who click a contractor's ad leave without calling, and most contractors never see them again. Here is how retargeting works for roofing, HVAC, plumbing, and electrical companies in 2026: which audiences to build, what it costs per platform, the creative that books, and the setup mistakes that quietly waste the budget.
