A brick, asphalt and paving company added postcards to its best-performing zones and grew year-over-year lead calls by nearly 30% – here’s the data roofing and paving owners can use to plan their own campaign.
For roofing and paving company owners, the marketing math is brutally simple: jobs are big-ticket, infrequent, and won or lost on whoever the homeowner remembers calling first. You don’t get many shots at a driveway or a roof – so when a channel proves it can keep your phone ringing year after year, it’s worth understanding exactly why it worked.
That’s the question behind this case study. A brick and asphalt paving company wanted to know whether increasing direct mail frequency – and layering in postcards on top of its regular mailings – would move the needle on lead volume. The results give roofing and paving owners a real, numbers-backed answer.
Why direct mail still works for roofing and paving companies
Roofing and paving are considered-purchase categories. Homeowners don’t decide on a whim – they research, compare quotes, and often wait until there’s a visible problem (a leak, a crack, a pothole) before they call anyone. That means:
- Repetition builds trust. A company a homeowner has seen in the mailbox for three seasons in a row reads as established and reliable – exactly what someone hiring for a $10,000+ roof or driveway job is looking for.
- Demand is driven by aging infrastructure and weather, not impulse. Roofing industry revenue is projected to reach roughly $92.5 billion in 2026, with about 80% of that activity coming from renovations and repairs rather than new construction – driven largely by aging housing stock and severe weather events (IBISWorld, 2026). Paving follows a similar pattern: the U.S. paving contractors industry (residential and commercial driveways and parking areas) is valued at an estimated $17.6 billion in 2026 across roughly 139,000 businesses (IBISWorld, 2026).
- Timing matters as much as targeting. Because the “need” for a new roof or driveway often shows up seasonally or after a storm, staying visible across multiple mailing windows (not just one) puts your name in front of homeowners closer to the moment they’re ready to call.
The case study: what changed, and what happened
The strategy:
- Blue Envelope mailings sent to 600,000+ homes across spring, summer and fall
- PlusOne postcards layered on top of Blue Envelope in select zones, to test performance with and without the additional touch
- Every piece carried a unique phone number, URL and QR code for call tracking
- Zones were matched to the company’s actual service area, not mailed broadly
The results:
- Lead generation calls grew from 1,081 in year 1 to 1,395 in year 2 across 60+ zones – a 29% year-over-year increase
- The two zones where postcards were added outperformed the rest by 30–70% in sales
- Those two postcard zones alone accounted for 37 of the company’s 229 jobs sold in year 2 – 15% of all business from just two zones
- Call tracking numbers were still generating calls years after they were first mailed: in year 2, 85% of calls came from that year’s numbers, but 14% still came from year 1 numbers, and a small share from numbers prior to the test.
That last point is the one roofing and paving owners should sit with. Direct mail with a good offer doesn’t just generate a short burst of calls — it keeps working long after the piece hits the mailbox, because homeowners hold onto mail (stuck to the fridge, tucked in a drawer) until the moment they actually need the work done.
What this means if you run a roofing or paving company
- Frequency compounds. One mailing is a coupon. Three seasons of mailings is a relationship. The jump in call volume here came from consistent presence across multiple mailing windows, not a single campaign.
- Layering formats outperforms a single format. Adding postcards on top of Blue Envelope mail, rather than choosing one or the other, is what produced the 30–70% lift in the top zones.
- Call tracking tells you where to double down. This company didn’t guess which zones to expand postcards into. It used call and sales data from prior years to decide, then scaled what was already working.
- Old mail still converts. Don’t judge a campaign’s ROI only by its first 90 days. A meaningful share of this company’s calls came from mailers over a year old.
FAQ: Direct mail for roofing and paving companies
Does direct mail still work for roofing and paving companies? Yes. Because roof and driveway purchases are high-consideration, low-frequency decisions, homeowners tend to hold onto mail until they’re ready to act, which is why this case study saw calls coming in from mailers up to three years old.
How often should a roofing or paving company mail? This case study mailed across three seasonal windows (spring, summer, fall) rather than a single campaign, and saw call volume grow each year that frequency was maintained.
Do postcards work better than envelope mail for roofing and paving leads? In this case study, postcards weren’t a replacement; they were an addition. The zones that layered postcards on top of existing Blue Envelope mail outperformed the other zones by 30–70%.
How do I know which zones to target with additional direct mail? Use call tracking and sales data from your existing campaign to identify your best-performing zones first, then expand frequency or add formats there — that’s the exact approach that drove this company’s results.
