What changed

Compared with Q2, management now describes weak residential construction and a second consecutive year of below-average storm activity as pressures on roofing shipments. Q3 included a $476 million Doors goodwill impairment, while the company still generated $489 million in adjusted EBITDA and $622 million in free cash flow.

Guidance delta
