Five hundred dollars a month can be enough to learn Google Ads in a small market, but it is rarely enough to fill a roofing crew if competition and job value are high. Whether it works depends on cost per click in your zip codes, how tightly you match keywords to landing pages, and how fast you answer leads.
Treat $500 as a test budget, not a full demand plan. Focus on a few high-intent search themes, such as the roof services you actually sell in your service area. Send clicks to a specific page, not the homepage. Turn on call tracking. Pause queries that attract DIY or tire-kickers. If the first two weeks produce clicks but no booked estimates, fix the offer and response time before raising spend.
Local Services Ads can stretch a small budget because you pay per lead, though lead prices still vary by market. Search ads and LSA often work better together than either alone. Roofing marketing that only buys clicks without Maps and review strength usually underperforms.
We do not publish a universal “enough” number because markets differ. Use $500 to prove tracking and close rate, then scale what books jobs.
