Executive Summary

CertainTeed posts an AI Authority Value of $1.97 million per month, placing it third in the roofing category behind GAF at $2.71 million and Owens Corning at $2.01 million. The benchmark reveals a company with strong recommendation quality and sentiment but a measurable visibility gap relative to its closest competitor.

CertainTeed appears in 67.8% of all AI responses across the three public high-intent clusters, compared to Owens Corning's 86.7% and GAF's 73.5%. This 19-point gap in raw mention presence is the primary structural disadvantage CertainTeed faces. However, CertainTeed converts visibility into recommendation credit more efficiently than Owens Corning. Its valid recommendation coverage rate of 31.2% is competitive with GAF's 32.5% and slightly below Owens Corning's 34.0%.

The rank-one story is where CertainTeed shows both strength and opportunity. Its 12.8% rank-one rate is higher than Owens Corning's 10.3% but trails GAF's 20.8% by a wide margin. CertainTeed's average recommended rank of 1.95 means that when it is recommended, it typically appears as the second choice. GAF's average recommended rank of 1.41 means it is almost always the first choice.

CertainTeed's net sentiment score of 0.53 is among the highest in the category, trailing only Malarkey at 0.55. This suggests that when CertainTeed appears in AI responses, the framing is predominantly positive. The company has only 2 negative mentions out of 767 total appearances, a 0.3% negative visibility rate.

The evaluation-stage comparison cluster is CertainTeed's strongest performance area, with a 36.7% top-three rate and an 18.5% rank-one rate. The decision-stage pricing cluster shows similar strength with a 25.7% top-three rate and a 12.2% rank-one rate. The consideration-stage cluster is the weakest, with a 24.6% top-three rate and a 9.1% rank-one rate.

What CertainTeed Is Winning

Strongest recommendation sentiment in the top tier. CertainTeed's net sentiment score of 0.53 is higher than GAF's 0.52 and Owens Corning's 0.49. The public evidence layer that AI systems retrieve for CertainTeed is more consistently positive than for either competitor. The company has only 2 negative mentions across 1,131 observations, indicating that cautionary or critical framing is rare.

Competitive recommendation conversion. CertainTeed converts 31.2% of its appearances into valid recommendations, nearly matching GAF's 32.5% and exceeding the category average. When AI systems mention CertainTeed, they frequently include it in the shortlist rather than treating it as a neutral reference.

Strong performance on Google AI Overviews. CertainTeed achieves a 35.5% top-three rate and a 13.2% rank-one rate on Google AI Overviews, paired with a net sentiment score of 0.71. This platform represents a growing share of AI-driven discovery for homeowners and contractors and is where CertainTeed's framing is most consistently positive.

Consistent platform performance. CertainTeed shows rank-one rates ranging from 6.6% on Perplexity to 17.1% on Google AI Mode, with no platform where performance collapses entirely. This consistency is a structural advantage over competitors like Owens Corning, which drops to a 1.3% rank-one rate on Perplexity.

Where CertainTeed Has the Clearest AI Visibility Gaps

Raw mention presence trails Owens Corning by 19 points. Owens Corning appears in 86.7% of AI responses versus CertainTeed's 67.8%. This gap means CertainTeed is absent from nearly one in five AI-generated responses where Owens Corning is present. The gap is most pronounced in the evaluation-stage comparison cluster, where Owens Corning appears at a 111.7% rate (multiple mentions per response) versus CertainTeed's 83.4%.

Rank-one rate trails GAF by 8 points. GAF achieves a 20.8% rank-one rate versus CertainTeed's 12.8%. In the evaluation-stage comparison cluster, the gap widens to 27.3% versus 18.5%. GAF is consistently positioned as the first recommendation, pushing CertainTeed to the second slot where buyer attention and conversion probability are lower.

Consideration-stage cluster is the weakest performance area. In the Best Roofing Shingles & Top Roofing Materials cluster, CertainTeed's rank-one rate drops to 9.1%, compared to GAF's 18.3%. This cluster represents buyers in the earliest stage of research, when brand awareness and initial shortlist formation occur. Weakness here allows GAF to establish a first-mover position before buyers reach the comparison stage.

Perplexity is the weakest platform. CertainTeed's rank-one rate on Perplexity is 6.6%, compared to 17.1% on Google AI Mode and 16.5% on Gemini. Perplexity accounts for a smaller share of total observations but represents a growing audience of technically sophisticated buyers who conduct detailed product research.

Biggest Opportunity

Close the rank-one gap with GAF in the evaluation-stage comparison cluster. The Roofing Shingles Brand & Product Comparisons cluster represents buyers actively comparing brands side by side and carries a $5.36 million monthly opportunity. CertainTeed's 18.5% rank-one rate trails GAF's 27.3% by nearly 9 points. Improving rank-one performance in this cluster by strengthening the citation signals that push CertainTeed to the top of AI-generated shortlists would directly increase captured recommendation value. The evidence suggests CertainTeed has the sentiment quality and product authority to compete at this level. The gap is in the specific comparison framing and trust markers that AI systems use to select the first recommendation rather than the second.

Prompt Evidence

Gemini / Roofing Shingles Brand & Product Comparisons Prompt: "Compare CertainTeed vs GAF roofing shingles" Result: CertainTeed appeared as a recommended option but was consistently placed second behind GAF in ranked recommendations.

Google AI Mode / Best Roofing Shingles & Top Roofing Materials Prompt: "What are the best roofing shingles for a residential home?" Result: CertainTeed was mentioned as a top-tier option alongside GAF and Owens Corning, with positive framing around product quality and warranty terms.

Perplexity / Roofing Shingles Pricing & Cost Prompt: "How much do CertainTeed roofing shingles cost compared to Owens Corning?" Result: CertainTeed appeared with pricing context but was less frequently recommended as the top choice, appearing more often as a comparison anchor than a primary recommendation.

What CiteWorks Studio Would Do Next

Phase 1: AI Market Discovery Audit Map the full prompt-level response data across all 10 buyer intent clusters to identify exactly where CertainTeed wins, loses, or is displaced by GAF and Owens Corning in AI-generated responses.

Phase 2: Recommendation Readiness Plan Analyze the citation sources driving CertainTeed's current recommendation patterns and identify which evidence layers are missing or underweight in the comparison and pricing clusters.

Phase 3: Owned Answer Layer Buildout Develop structured product comparison content, warranty documentation, and pricing pages designed to be retrievable and synthesizable by AI systems, with particular focus on the evaluation-stage comparison cluster.

Phase 4: Citation / Authority Layer Development Strengthen the public evidence layer through independent review signals, installer directory listings, and building code compliance records that AI systems can cite as authoritative sources when forming comparison recommendations.

Phase 5: Monthly AI Visibility and Recommendation Tracking Establish ongoing measurement of CertainTeed's recommendation coverage, rank position, and sentiment across all six platforms to track progress against GAF and Owens Corning across all observed clusters.

Why This Matters

Homeowners and contractors searching for roofing materials now encounter AI-generated shortlists before they see traditional search results. CertainTeed is present in these shortlists but is systematically placed behind GAF in the top recommendation slot. This is not a visibility problem. CertainTeed has strong recommendation quality and the highest sentiment score in the top tier. The gap is in the specific citation signals and comparison framing that push a brand from second choice to first choice at the moment a buyer forms their shortlist.

The commercial cost of this gap is measurable. CertainTeed's modeled monthly lost AI opportunity value is $16.2 million. Closing the rank-one gap in the evaluation-stage comparison cluster alone would shift a meaningful share of that lost value into captured recommendation credit. The next move is not broader visibility. It is targeted correction of the prompt, page, and citation layers that determine whether CertainTeed is recommended first or second when a buyer asks AI which roofing brand to choose.

Sentiment Score

Sentiment Score = (positive mentions x 1 + neutral mentions x 0 + negative mentions x -1) / total mentions

CertainTeed Sentiment Score = (411 x 1 + 354 x 0 + 2 x -1) / 767 = 409 / 767 = 0.53

This score matters because unclassified mention counts are misleading. CertainTeed appears in 767 AI responses, but 354 of those are neutral references that carry no recommendation credit. Counting all 767 appearances as wins would overstate CertainTeed's commercial influence in the category. A positive recommendation, a neutral reference, a cautionary mention, and a competitor-displaced mention are not the same signal, and treating them as equivalent produces a distorted picture of where a brand actually stands. Classified sentiment is required before interpreting AI visibility. CertainTeed's 0.53 score indicates that the majority of its framed mentions are positive, which is a strong foundation for improving recommendation rank without needing to rehabilitate brand perception.
