If you have asked a marketing company how much you should spend on Google Ads for your roofing business, you have probably received an answer that did not fully satisfy you. Either it was a number with no explanation of why, or it was a broad range with a lot of “it depends,” or it was framed around what your competitors are spending without explaining what that should mean for your goals.
The honest answer is that the right budget depends on your market, your job mix, and what you need the ads to produce. But there is a real framework for thinking through it, and there are also real minimums below which roofing ads do not work no matter how well the account is set up.
The Math Behind a Roofing Budget
Roofing is a high-value service. A full replacement can run anywhere from eight thousand dollars to twenty thousand dollars or more depending on the home, the materials, and the market. Emergency repairs and insurance jobs span a wide range. Even a conservative job value makes the math more favorable than many other service businesses, which means there is room to spend meaningfully on advertising if the leads are qualified.
The way to think about budget is to work backward from the job, not forward from the ad spend.
Start with your average job value: say twelve thousand dollars for a replacement. Figure out what margin you need to keep: say you want at least forty percent. That means you can spend up to roughly seven thousand dollars to acquire a single replacement job and still hit your target. In practice you would set a much lower acquisition cost threshold to leave room for variability, but the point is that roofing companies can afford to spend significantly more per lead than most service businesses because the underlying job value supports it.
Now think about your close rate. If you run ten inspections and close four jobs, you are closing forty percent of booked inspections. If you can afford to spend five hundred dollars per closed job, you can afford to spend two hundred dollars per booked inspection.
The remaining question is how many clicks it takes to produce a booked inspection in your market. That depends on how well the account is set up, how competitive the market is, and what kind of work you are targeting.
What Clicks Actually Cost in Roofing
Roofing is one of the more expensive advertising categories in local service businesses. In most markets, a click on a roofing keyword costs somewhere between fifteen and forty-five dollars. In large metro areas, in competitive markets, and during the period immediately following a major storm, costs at the higher end of that range or above are common.
That means reaching a homeowner through a Google Ad, before they have done anything other than click, costs fifteen to forty-five dollars. If ten percent of clicks produce a phone call, you are spending one hundred fifty to four hundred fifty dollars per call. If half of those calls produce a booked inspection, you are at three hundred to nine hundred dollars per booked inspection. If you close forty percent of inspections, you arrive at a cost per closed job that ranges from seven hundred fifty dollars to twenty-two hundred dollars.
These numbers are not universal. Better-optimized accounts produce higher contact rates from clicks. Better ads produce higher call-to-inspection rates. Better targeting reduces the share of clicks that come from unqualified searchers. The numbers improve as the account is refined over time. But they illustrate why a five-hundred-dollar monthly budget does not work in most roofing markets.
The Minimum That Actually Works
A budget that is too small for the market produces a specific set of problems.
With a small budget, the campaign exhausts daily spend before the end of the day and stops showing ads for the remainder. If you set a fifty-dollar-per-day limit and clicks cost thirty dollars each, the campaign reaches its cap after roughly one or two clicks in the morning and goes dark for the rest of the day. Homeowners searching in the afternoon and evening, when many people research home service decisions, do not see your ads.
A limited budget also means limited data. Google’s bidding system learns which searches produce your conversions by observing patterns over time. A campaign that generates only a few calls per month does not produce enough data for the system to identify meaningful patterns. The system stays in a low-confidence state, making less accurate bid decisions, which produces fewer calls, which produces less data. The campaign gets stuck.
The minimum budget that produces enough volume to generate real data and reach homeowners throughout the day varies by market. In a mid-size city with moderate competition, that minimum might be fifteen hundred to two thousand dollars per month. In a large metro with significant competition, two thousand five hundred to four thousand dollars or more may be needed before the account has enough budget to compete for placements and accumulate useful data.
Spending below that threshold in a competitive market is not just inefficient. It often means the account is technically running but producing near-zero results, which leads to the conclusion that Google Ads does not work for roofing when the actual problem was budget.
Market Size Changes the Number
A roofing company in a large metropolitan area competing for terms like “roofer in Houston” or “roof replacement Denver” is in a different competitive environment than a contractor in a smaller city of fifty thousand people.
In large metros, more contractors are bidding for the same searches. More national brands and storm chasers enter the market. Clicks cost more because competition is higher. The budget required to maintain a meaningful presence is correspondingly higher.
In smaller markets, the competitive landscape is thinner. Clicks are cheaper. Reaching a larger share of the relevant homeowners requires less spend. A well-structured account in a mid-size market can produce qualified inspections at a cost that would be impossible in a major metro.
This is why a specific dollar figure offered without reference to the market is not very useful. The number that works for a roofing company in a suburb of Chicago is genuinely different from the number that works for a roofing company in a smaller city in the Midwest.
The Ramp-Up Period
A roofing campaign that is new, or that has been rebuilt, needs time to accumulate data before it performs at its potential.
In the first few weeks, the bidding system is learning. It does not yet know which searches in your specific market produce calls, what time of day produces the best leads, or which geographic areas within your service footprint convert at higher rates. It makes bidding decisions based on broad signals rather than account-specific patterns.
Over the first sixty to ninety days, as calls and form submissions accumulate, the system learns. Bids become more accurate. The allocation of budget shifts toward the searches that produce results. Cost per lead typically improves during this period as the system calibrates.
This means the first two to three months of a roofing campaign should be viewed as the learning period, not the steady-state performance period. Evaluating a new campaign against the performance standards of a mature, well-optimized account will produce a false picture.
It also means starting with an undersize budget has a compounding cost: the campaign takes longer to gather data, which extends the learning period, which delays the point at which it performs well.
How to Think About Value, Not Just Cost
The question “how much should I spend” is easier to answer if it becomes “what am I willing to pay per booked inspection, and how many inspections do I want per month.”
If you want ten booked inspections per month and you are willing to pay two hundred fifty dollars per inspection, you need a budget of at least twenty-five hundred dollars per month. Whether that budget actually produces ten inspections per month depends on how well the account is set up, how competitive the market is, and how the account is managed.
A budget conversation that stays at the level of total monthly spend misses this. The number that actually matters is whether the cost per inspection and the volume of inspections meet your business goals. Budget size is a means to that end, not the goal itself.
Getting This Fixed
Modeling what a realistic roofing ad budget looks like for your market, your job mix, and your goals, and then building an account that can actually hit those targets, is exactly the kind of work I do for local service businesses.
