Selected homes produced the strongest result. Writing to each house nearly doubled signed contracts inside that list.
Four equal groups of 32,000 homes. Two mailing lists, two kinds of mail, signed roofing contracts counted. The winner signed 240. Below is every group, every count, and every limit, because you should be able to check us, not trust us.

Nothing hidden
Four separate groups. 32,000 homes each.
One good number can hide a weak test. Here are all four groups side by side, so you can see exactly what did the work.

The part that was dealt randomly
Same selected list. The letter alone signed 92% more.
Two groups of 32,000 came from the same selected list. Which homes got which letter was dealt randomly, so the letter is the only thing that changed. The letter written around each house signed 240. The ordinary letter signed 125. That is 115 more signed roofs,92% more, from the writing alone.

Read this one carefully
240 versus 35 is the real result. It is not the proof.
Chosen homes with mail written to the house signed 240. The broad list with ordinary mail signed 35, across two 32,000-home groups. That gap is the complete strategy working together, and it is the strategy we run.
Here is the honest part: the two lists were not dealt randomly, so we cannot prove the picking did it alone. Some of that gap may come from the lists themselves. So take 6.86× as a reason to test the complete system in your market, not as a number we promise to repeat.
What this page will not claim
One field result. Not a forecast.
- This happened once, in one market, for one company. Your market has to prove itself.
- Brand, market, timing, offer, crew room, and follow-up all move the number. Yours will be different.
- The 92% is the letter, measured inside the same selected list. Those two groups were dealt randomly.
- The 240-versus-35 comparison was not dealt randomly. It shows the complete strategy, not picking alone.
- Roof age tells us where a roofing conversation is worth having. Only your inspection tells you the condition.
- If a mailed roof is more than five years newer than our estimate, we credit that selected home. Exact terms are in your written campaign quote.
