Roofing Post-Storm Response: 6.8% Response on a 900-Piece Hyperlocal Drop

The challenge

Summit Ridge Roofing competed in a Dallas market where the post-storm landscape was a knife fight. Out-of-state storm chasers descended on hail-affected neighborhoods within 24-48 hours, knocking on doors with high-pressure pitches and often disappearing after collecting insurance checks. The owner ran a legitimate, locally-based, insured operation — and was consistently losing the first-mover battle for damaged-roof inspections to fly-by-night door-knockers.

On April 14, a confirmed hail event with 1.5"+ hailstones swept across a 4-mile-wide swath of his service area. He needed to be in those mailboxes within 72 hours — before the storm-chaser caravan finished door-knocking the neighborhood. Existing marketing channels (Google Ads, Facebook) couldn't geofence tightly enough or fast enough. He needed a postcard system that could ingest a hyperlocal address list, push approved creative, and drop within a 72-hour window.

The owner had pre-built a storm-response template in PostKnock during his onboarding — based on the playbook — but had never deployed it. April 14 was the test case. The address list came from a publicly-available NOAA hail-swath polygon overlaid on the local property database, filtered to single-family residential. The list came back at 900 households — small enough to mail fast, large enough to matter.

The PostKnock approach

Playbook used: Storm Response Hyperlocal

We deployed PostKnock's Storm Response Hyperlocal playbook with a pre-built template that the owner had configured during onboarding. The hail-swath polygon was uploaded as a CSV of 900 addresses; the template populated the ZIP-and-storm-date personalization automatically ("April 14 hailstorm — your roof may have damage you can't see from the ground"). Drop authorization happened within 18 hours of the storm, with mail in mailboxes 4-5 days post-event — well inside the storm-chaser window.

Wave 1 was a 6x9 postcard with a high-contrast headline ("Free post-storm roof inspection — local, licensed, here when the chasers leave") and explicit anti-storm-chaser positioning ("Our office has been here since 2014. We don't disappear."). The card carried a QR code linking to a pre-filled inspection-request form and a callback line. The visual was a clean photo of a recent local job, not stock — credibility was the conversion driver, not slick design.

There was no phone follow-up; the owner deliberately avoided proactive cold-calling because in a storm-response context it reads as predatory. Inbound response was strong: 28 inspection requests within 10 days, plus 12 phone callbacks the dispatcher fielded directly. Wave 2 was held back — the owner's preference, given crew load — and the campaign was treated as a single-wave hyperlocal blitz. Total: 900 pieces, 14-day active window.

Campaign timeline

May 1-15

Insurance scoping + claim filing. 12 of 18 progress to scheduled re-roof.

Results

Twenty-eight inspection requests on 900 unique households is a 6.8% response rate that lands at the high end of the 5-8% storm-response window — exceptional because (a) the targeting was hyperlocal-by-actual-damage, not blanket-mail, and (b) the timing landed inside the homeowner's awareness window. Of those 28, 18 had real insurable damage and 12 progressed to scheduled re-roofs. Average insurance-claim re-roof at this market is $8,200 (mid-range tier-2 shingle, full tear-off), giving $98,400 in committed revenue.

Campaign cost ran $3,160 — $540 in postcards (900 at $0.60), $99 for one Pro-month (the campaign closed in 2 weeks), and $2,521 in NOAA-list pull + dispatcher inspection coordination. ROI of 31x is the headline, and unlike more speculative marketing, this revenue is largely insurance-funded and high-margin. Six of the 16 "no-damage" inspections converted to a future inspection appointment for the next storm cycle, and the owner's reputation in the storm-affected neighborhood lifted notably — he's now booked through Q3.

“The chasers had three days. We had a week to land in the mailbox before they left town. PostKnock got us there in four. That's the whole game.”

What we’d do differently

• Pre-built storm-response template was essential. We could not have moved fast enough if we'd been designing from scratch the day of the storm. Setting up the template at quiet time pays off in chaos.
• Anti-storm-chaser positioning resonated more than offer-based. Customers in a chased neighborhood want a reason to NOT call the door-knocker. "Local, licensed, here in 2014" did that work.
• We should have set up an SMS opt-in CTA on the card for future storm events. Two homeowners told the inspector "send me a text next time" — a reactivation channel we left on the table.
