"How much should I spend on Google Ads?"
Every roofer asks this question. And every agency gives the same useless answer: "It depends on your market."
That's technically true and practically worthless. You're a business owner trying to plan a budget. You need numbers, not hedging. So here are real numbers, based on what I see running paid media for contractors in competitive Florida markets and what I know from 15+ years of building websites that actually need to convert the traffic those ads send.
The Three Budget Tiers
Here's what each spending level can realistically deliver. I'm using conservative assumptions: $30 average CPC, 5% landing page conversion rate (meaning 5 out of every 100 visitors call or fill out a form), and 30% close rate on those leads.
Tier 1: $1,000/month — Testing the Water
[Comparison table — see full post for details]
At $1,000/month, you're running a pilot program. You'll get enough data to see which keywords get clicks, what your actual CPC looks like, and whether your website converts the traffic. You probably won't generate consistent revenue from ads alone at this level.
Who this works for: Roofers who are new to ads and want to learn the system before committing serious budget. Also works if you're in a smaller market with less competition where CPCs run lower.
The honest truth: $1,000/month in roofing Google Ads is a learning budget, not a growth budget. If you expect 10 leads a month at this level, you'll be disappointed and blame the ads when the problem is the math.
Tier 2: $3,000/month — Competitive Presence
[Comparison table — see full post for details]
Now we're in a range where the math starts working. At 5–7 leads a month, you have enough volume to close 1–2 jobs. At $10,000 average job value, you're generating $10,000–$20,000 in revenue from $3,000 in spend. That's a 3–6x return on ad spend (ROAS — the number that matters).
Who this works for: Established roofers who want consistent lead flow beyond referrals. This is the sweet spot for most roofing companies doing $500K–$2M in annual revenue.
The key requirement: Your website needs to actually convert. If your roofing website isn't built for conversions, you'll burn through $3,000/month getting clicks that bounce. Fix the site first, then turn on ads.
Tier 3: $5,000+/month — Market Dominance
[Comparison table — see full post for details]
At $5,000/month, you're showing up for the majority of high-intent roofing searches in your market. Your ads appear at the top of the page for storm damage, roof replacement, roof repair, and branded competitor terms. You're generating enough lead volume to keep your sales team busy and your crews booked.
Who this works for: Roofing companies doing $2M+ that want to own their market. Multi-crew operations that can handle the job volume. Companies in highly competitive markets like Sarasota, Tampa, or Miami where $3,000/month gets outbid.
The scaling note: There's a ceiling in every market. At some point, throwing more money at Google Ads produces diminishing returns because you've captured most of the available search volume. For most metro areas, that ceiling is $8,000–$12,000/month for roofing. Beyond that, your growth dollars are better spent on SEO or other channels.
The 5 Mistakes That Waste Your Roofing Ad Budget
I've audited hundreds of Google Ads accounts for contractors. These five mistakes show up in almost every one that's underperforming.
1. Sending ad traffic to your homepage
Your homepage is designed for everyone — homeowners, commercial clients, insurance adjusters, people who Googled your company name. When someone clicks an ad for "roof replacement Sarasota," they should land on a page specifically about roof replacement in Sarasota. Not your homepage. Not your generic services page.
A dedicated landing page with conversion optimization built in — matching headline, specific service info, local trust signals, one clear CTA — converts 2–3x better than a homepage. At $30 per click, that's the difference between paying $600 per lead and $200 per lead.
2. Bidding on informational keywords
"How to fix a leaky roof" and "roof shingle types" get lots of searches. They also attract people who are Googling because they want to DIY, not hire. If you're spending $20 per click on someone who wants a YouTube tutorial, that's wasted budget.
Focus your budget on commercial-intent keywords — phrases that signal someone is ready to hire. "Roof replacement near me," "roofing company Sarasota," "storm damage roof repair" — these people are looking for YOU, not a how-to article. Save the informational keywords for your blog and SEO strategy.
3. No negative keyword list
Negative keywords tell Google "don't show my ad when someone searches this." Without them, your roofing ads will show up for "roofing jobs hiring," "DIY roof repair," "roofing shingle prices Home Depot," and dozens of other searches that will never become a customer.
Every roofing account needs a negative keyword list from day one. Common ones: "jobs," "hiring," "salary," "DIY," "Home Depot," "Lowes," "free," "cheap." Review your search terms report weekly and add new negatives as you spot wasted clicks.
4. Not tracking calls
If you're running Google Ads and not tracking which phone calls came from which ads, you're flying blind. You have no idea which keywords generate jobs and which generate tire-kickers.
Call tracking isn't optional — it's the foundation of knowing whether your ads work. Google's built-in call tracking is good enough to start. Dynamic number insertion on your landing pages is better. The point is: every call needs to be attributed back to the keyword that generated it.
5. Running ads to a slow website
Your ad loads in 0.3 seconds. Your website takes 6 seconds to load. In those 5.7 seconds, 40% of your visitors leave. You just paid $30 for a click that never saw your page.
Page speed matters everywhere, but it matters most with paid traffic because every slow-loading page is literally burning money. If your site takes more than 3 seconds to fully load on mobile, fix that before you spend another dollar on ads. A website built for speed is a prerequisite for profitable Google Ads.
Before You Spend a Dollar
Honest advice from someone who doesn't make money on your ad spend (clients always pay Google directly — I don't mark it up):
- Fix your website first. If your site doesn't convert visitors into calls, ads just send expensive traffic to a dead end. Get a free site audit to see where you stand.
- Start with $1,500–$3,000/month. Enough to gather real data without blowing your budget on month one learning.
- Expect 60–90 days before the account is optimized. Google Ads accounts get better over time as you build data, add negative keywords, and refine your targeting. Month one is always the worst month.
- Track everything. Calls, forms, cost per lead, cost per job. If your agency can't tell you exactly how much each job costs to acquire, something is wrong.
