Six-nail or four-nail pattern? Why does it matter?

Almost every shingle wind rating you see advertised assumes a 6-nail installation pattern. Drop to 4 nails and the rated wind speed cuts roughly in half. Trill installs every shingle with the 6-nail pattern as a standard, regardless of what code minimum allows.

The cost difference is negligible — maybe an extra $80 of nails on a typical job and 30 minutes of labor. The performance difference is enormous. We have on file before/after photos of two adjacent Brighton homes hit by the same May 2024 storm: 4-nail (code-min) had 38 shingles peel; 6-nail (Trill standard) had two. Same shingle brand, same crew, same weather. The pattern matters.
