A focused postcard plus phone-follow-up playbook designed for one job: getting past customers and post-storm prospects on your inspection schedule.
By the time a homeowner sees a stain on the ceiling, the cheap fix is gone. Annual inspection campaigns get you in the door before the emergency — which is when the contractor on the postcard from last spring becomes the contractor of record.
2 waves over 4 weeks, twice a year (spring + fall). Below is exactly what mails when, and why.
Headline: "Your roof is X years old — get a free inspection before the next storm" · Offer: Free 30-minute inspection · QR to online booking.
Mailed in early spring (post-winter check) or early fall (pre-winter prep). Free inspection offer is low-friction, builds trust, and sets up the upsell. Phone follow-up 10–14 days later: "Wanted to make sure you got our card — can we get you on the schedule this week?" 70%+ of inspections come from this wave.
Headline: "Storm season fills up our schedule fast" · Offer: Same free inspection, expedited scheduling.
Mailed 28 days after Wave 1 only to non-responders. Different angle: timing. "We're booking inspections through [date] — book now to get yours before the rush." Avoid scare tactics — focus on capacity and timing rather than damage.
All wave timing, call scripts, and copy direction are pre-configured for inspection campaigns. You only customize the offer (free inspection, $50 off any repair, etc.) and your contractor branding.
Export past customers from JobNimbus, AccuLynx, Roofr, or your CRM as CSV. For storm response, pull homeowner lists by zip + carrier route from ListSource or Cole Realty Resource. Our import wizard auto-maps the columns.
Wave 1 postcards print and drop into USPS within 1–2 business days. Your call queue populates 10 days after delivery. Wave 2 schedules itself 28 days later, only mailing non-responders.
Each call has a pre-loaded script. Crew schedulers log the outcome (booked, voicemail, declined). Booked inspections drop out of the sequence automatically.
Most roofing contractors have 500–1,500 past customers in the last 5 years. Here's the math on an 800-customer run:
24:1 ROI on the first cycle — before referrals from the inspection visits.

Annual inspection is the highest-ROI roofing playbook, but PostKnock also runs storm-response canvassing, past-customer reactivation, and seasonal promos. See the full lineup on the roofing hub.
300–1,000 customers for the first run. Smaller than 300 and the per-card economics get tight; larger than 1,000 and your inspection schedule may not handle the response. If you have 2,000+ past customers, split into two cohorts and stagger by 30 days.
After a major hail or wind event, pull homeowner lists by zip + carrier route in the affected area from ListSource, ProspectsPLUS, or Cole Realty Resource. Upload to PostKnock as CSV. Mail within 7–10 days while the storm is top of mind. Free inspection offer typically converts at 2–5% on storm-affected zips. PostKnock's 1–2 day print SLA means you can launch quickly.
Yes — the math works because of the upsell rate. About 30% of inspections turn up at least one repair-worthy issue, and 15–20% turn into full-roof replacements within 12 months. The cost of an inspection is your crew time + a small written estimate; the upside is a $5K–$25K+ project.
Spring (Feb–Apr): post-winter damage check — ice damming, missing shingles, gutter damage. Fall (Aug–Oct): pre-winter prep — flashings, soft spots, attic ventilation. Two campaigns a year is the sweet spot. More than that trains customers to ignore your cards; less and a competitor lands first.
Yes — most states require licensed contractors to include their license number on advertising materials. PostKnock templates leave space for required disclosures. Confirm specific requirements with your state contractor licensing board.
Stop relying on storm chasers. Start running the inspection cadence that builds long-term repeat business.
