Benchmark Summary

Questions This Section Answers

  • Which roofing brand leads the benchmark on valid recommendation coverage?
  • How much did AI recommendations move across roofing brands in October 2026?
  • What are the largest coverage gains and declines since the July 2026 baseline?

The Roofing Companies benchmark ended October 2026 with GAF as the coverage leader at 53.6% valid recommendation coverage, ahead of Owens Corning at 51.7%, a gap of 1.9 points. No brand recorded a significant month-over-month move in October 2026, so the month reads as mixed rather than directional.

Across the full series, the largest coverage increase from the July 2026 baseline came from Atlas Roofing, which rose to 26.2% valid recommendation coverage in October 2026 from 20.4% in July 2026, up 5.8 points. The largest coverage decline from baseline was DECRA, which fell to 0.0% in October 2026 from 0.9% in July 2026, down 0.9 points.

The benchmark began with 800 prompt-surface observations in each month and produced 534 qualified observations in October 2026 after qualification, compared with 533 in July 2026.

Presence moved from 37.0% in July 2026 to 35.6% in October 2026, a decline of 1.4 points that sits within normal month-to-month variation.

Largest Decline: DECRA

DECRA recorded valid recommendation coverage of 0.0% in October 2026, down from 0.9% in July 2026, a decline of 0.9 points from baseline. The brand appeared in 0 valid recommendation shortlists out of 534 qualified observations in October 2026, compared with 5 out of 533 in July 2026. Presence fell from 3.2% in July 2026 to 0.4% in October 2026, a decline of 2.8 points. The brand registered 0.0% coverage in both September 2026 and October 2026 following a gradual step down of 0.9% in July 2026, 0.2% in August 2026 and 0.0% in September 2026.

Category Leader: GAF

GAF leads the index at 53.6% valid recommendation coverage in October 2026, up from 48.4% in July 2026, a gain of 5.2 points from baseline.

Its cumulative movement remains within normal variation and does not yet meet the threshold for a trend.

Evidence and Source Layer

The benchmark is built from prompt-level observations that retain the query, AI/search surface, answer, brand outcome, recommendation placement, sentiment, and, where exposed, citations or attributable evidence sources. Source presence is evidence about the information environment. It is not automatically proof that the source caused the recommendation.

Scope Boundaries

This public benchmark does not measure:

  • Market share or sales attribution
  • Every possible AI response to a given query
  • Organic-search ranking positions
  • Social mention volume
  • Private or sponsored channels (for example, brand-specific apps or paid placements)
  • Causality from a metric movement alone
