         NCI BUILDING SYSTEMS REPORTS THIRD-QUARTER EARNINGS AHEAD OF
                     GUIDANCE AT $0.36 PER DILUTED SHARE

                                   ----------

             ESTABLISHES EARNINGS GUIDANCE FOR THE FOURTH QUARTER

HOUSTON (AUGUST 27, 2003) - NCI Building Systems, Inc. (NYSE: NCS) today
announced earnings of $0.36 per diluted share for the three months ended August
2, 2003, compared with the Company's established guidance for the quarter in a
range of $0.32 to $0.35 per diluted share. NCI's sales for the third quarter of
fiscal 2003 were $236.3 million versus $257.8 million for the third quarter of
fiscal 2002, and net income was $6.8 million for the latest quarter compared
with $12.6 million, or $0.67 per diluted share, for the same period in fiscal
2002.

         Sales for the first nine months of fiscal 2003 were $643.3 million
compared with $699.6 million for the first nine months of fiscal 2002. Net
income was $12.7 million, or $0.67 per diluted share, for the first nine months
of fiscal 2003 versus a net loss of $44.6 million, or $2.39 per diluted share,
for the comparable period in fiscal 2002, which included a charge to earnings
resulting from a change in accounting principle of $65.1 million or $3.49 per
diluted share.

         Johnie Schulte, Jr., President and Chief Executive Officer, commented,
"We were again pleased with NCI's relative financial and operating performance
for the third quarter of fiscal 2003, which slightly exceeded our expectations.
Although our comparable-quarter results demonstrate that demand has remained
slow in the nonresidential construction business, NCI benefited from the
expected seasonal increase in construction activity. This increase enabled the
Company to improve its operating results compared with the second quarter of
fiscal 2003, more than tripling the second quarter's net income of $2.0 million
or $0.11 per diluted share. As we have experienced throughout fiscal 2003, our
profitable operations and substantial cash flow are in contrast to many of our
industry peers. In addition, we continued to strengthen our financial position
through a further reduction in long-term debt of nearly $25 million during the
third quarter, improving our debt to total capital at the quarter's end to 45.0%
from 49.0% at the end of fiscal 2002."

         A.R. Ginn, Chairman of the Board, added, "While NCI is not immune to
the impact of the lackluster nonresidential construction market, it has
performed well compared with its industry peers because of its continuing focus
on low cost operations, outstanding customer service, product innovations and
broad product line. As a result, we have consistently increased our market share
in spite of the difficult operating environment of the past two years, which we
expect will position the Company well for any market recovery.

         "In addition to debt reduction, we have used our cash flow to launch
new initiatives both to enhance our sales and improve our efficiency. The
investment in our new frame plant in Lexington, Tennessee, which is on schedule
for a fourth-quarter opening, is an example of the latter category, not only
because of the increased operating efficiencies we expect it to provide, but
also because it will enable us to close a less efficient plant. Recent
initiatives to improve sales include the acquisition of our fifth NCI Metal
Depot retail store in Baytown, Texas. In addition we opened our sixth retail
store during July, which is our flagship store located in Waller, Texas. A
logical extension of our leadership position in the metal construction industry,
NCI Metal Depot stores enable us to provide a wide range of commercial and
residential metal components and accessories, as well as a variety of small
metal building packages, directly to do-it-yourselfers, farmers and small
contractors, which are markets not normally served by our other distribution
channels.

         "While we believe that NCI's fourth-quarter results will again benefit
from seasonal volume, industry data and our experience indicate the
nonresidential construction market continued to contract through the first half
of calendar 2003 compared with the prior year. Based on NCI's performance to
date for fiscal 2003, we are confident of the Company's ability to continue
outperforming the metal construction segment of the overall industry during our
fourth quarter. However, with no sustained signs of improved industry demand, we
continue to temper our guidance, with expectations of earnings per diluted share
in a range of $0.40 to $0.43 for our last quarter of fiscal 2003. Although our
short-term earnings visibility beyond the current fiscal year is limited, we
remain well positioned to withstand the continuing challenges of this economic
cycle, both on an absolute basis and relative to our industry peers, and to
profitably leverage any significant improvement in the cycle."

         NCI Building Systems, Inc. is one of North America's largest integrated
manufacturers of metal products for the nonresidential building industry. The
Company operates manufacturing and distribution facilities located in 16 states
and Mexico.

financial indicator in the metal construction industry of a company's ability to
finance its operations and meet its growth plans. This measure is also used by
NCI internally to make acquisition and investment decisions.
