Owens Corning swung to a loss and logged lower sales in the third quarter, as weak demand trends hurt volumes across multiple businesses.

The Toledo, Ohio, maker of building materials on Wednesday posted a loss of $494 million, or $5.92 a share, compared with a profit of $321 million, or $3.65 a share, a year earlier.

The company recorded a non-cash impairment adjustment in its doors business, which Chief Financial Officer Todd Fister said reflected the weak near-term market environment.

Stripping out one-time items, earnings were $3.67 a share. Analysts polled by FactSet expected adjusted earnings of $3.71 a share.

Sales slipped 2.9% to $2.68 billion, compared with Wall Street views of $2.7 billion.

Roofing sales edged 1.6% higher, to $1.24 billion. The gain was offset by insulation sales, which fell 6.6% to $941 million, and doors sales, which fell 4.9% to $545 million.

"Our third-quarter financial results continue to demonstrate our ability to perform at a high level even in the face of challenging market conditions, as we see weakening residential demand trends in the U.S. impacting our volumes in both repair and remodel and new construction product lines," Chief Executive Brian Chambers said.

Looking ahead, Owens Corning expects sales to remain pressured in the current quarter. It guided for fourth-quarter sales of $2.1 billion to $2.2 billion, missing analyst projections for $2.46 billion.

The company forecast demand for non-discretionary roofing repair activity to decline significantly in the fourth quarter, in part citing lower storm activity. At the same time, residential new construction and remodeling remain pressured, with softer market conditions and year-end inventory destocking hurting the business.

These headwinds will be partially offset by minimal tariff exposure, thanks to the company's mitigation efforts. It expects to reduce its approximately $50 million tariff exposure to a net impact of about $10 million in the fourth quarter, Owens Corning said.

Shares fell 2.4% to $119.81 in premarket trading.
