Thanks, Brian, and good morning. Now let's turn to Slide #4 titled Gibraltar. First, I'll remind you that I'll be discussing adjusted income and margins, excluding special and nonroutine transactions. So starting with the consolidated first quarter results and comparisons, revenues decreased on the headwind of harsher winter conditions. The 3% decrease in consolidated revenues was comprised of a 2% volume decrease and a 1% pricing decline. Each reporting segment experienced the same proportional effects from the volume and pricing. And I'll provide more color on the relative strength of marketing conditions when I discuss each segment.
The first quarter's adjusted operating margin decreased by 240 basis points, primarily on a lower gross margin resulting from the weather-driven decrease in sales volume, a less favorable product mix in 1Q 2013, pricing adjustments and a raw material inflation for resins. Regarding the weather, certain winter storms caused short-term closures of multiple facilities, which led to among other effects, inefficiencies in production plus increased fuel costs for transport delays and longer routes.
DEPS comparison from last year's earnings of $0.04 per share to a $0.05 loss this quarter resulted from an $0.08 decline from lower demand for our Residential Products, driven by the prolonged harsher winter weather, which depressed reroofing activity throughout much of the U.S., plus pricing reductions and increased resin costs, which affect certain ventilation and postal [ph] products. The $0.06 decline from the Industrial & Infrastructure Products segment, largely attributable to lower volume including the weather-driven delays at construction sites causing contractors to postpone certain deliveries beyond the first quarter. This segment's profitability was also hurt by a less favorable mix of sales from the first quarter last year. And the combined segments' decreases were partially offset by a $0.05 improvement from lower compensation expense.
While our previous guidance for the first quarter 2014 is not depicted on Slide 4, we were short of our guidance on sales and earnings. After our February 20 earnings call, the extended winter weather weighed down results compared to our guidance. And it is difficult to determine precisely the weather impact on the first quarter. But we did have specific end customers unexpectedly request shipment delays for construction sites not being ready, which were worth nearly $3 million in sales value. Plus there were lower sell-through rates by our distributors, which our distributors attribute to prolonged winter conditions. Combining these 2 factors, I've estimated the weather effect on the first quarter being $6 million to $7 million of sales and $0.05 per share, including the incurrence of cost-related inefficiencies.
Next, I'll talk about each of our 2 reporting segments, starting with Slide #5, the Residential Products segment. Its first quarter sales decreased 3%, 2 percentage points on lower volume and 1 percentage point from pricing. As cited earlier, the winter weather was a major factor but a temporary factor as we expect underlying demand to come back in subsequent periods. Our roofing-related products, which provide rain dispersion and attic ventilation, were equally affected by lower remodeling and repair activity and, to a lesser extent, recently fluctuating levels of new residential construction. Our postal storage solutions had equivalent sales volume compared to a very good first quarter 2013. And as an aside, we thank snowplow drivers everywhere. This segment's operating income for the quarter declined, hurt by the nearly equivalent factors of weather-related lower volume, pricing adjustments and raw material inflation for resins.
Now let's turn to Slide #6, our Industrial & Infrastructure Products segment. Its first quarter sales also declined 3 percentage points, reflecting weather-related lower volume and a less favorable product mix in the first quarter a year ago. Among this segment's major product categories and end markets served, expansion joints and bridge bearings for the transportation infrastructure market were most affected. We rescheduled certain deliveries to beyond the first quarter of this year as requested by contractors, whose job sites were affected by winter conditions. And these delivery postponements amount to nearly $3 million of revenue. This segment also had a less favorable product mix than the first quarter a year ago. And during the first quarter of 2013, this segment shipped its last releases to key bridge and airport projects in California and Florida as well as higher volume of pavement sealing products.
This segment's other industrial products, including grating and expanded metal fabrication, rose compared to last year, driven by volume increases from discrete and process manufacturing customers in North America and Europe. For the 2 geographies we serve of North America and Europe, sales volume for these products increased year-over-year for the second consecutive quarter. So we're hopeful that recovery in industrial markets, which use our grating and expanded metal products, becomes a sustainable trend throughout 2014.
Industrial end markets, which provided incremental revenue for our products this quarter included chemical refining, mining in the Western U.S. as well as exports to South America plus power generation with cogeneration in hydro plants in the U.S. and wind power in Canada. There was little change from markets of oil and gas production and there was lower volume from coal mining and architectural facades. This segment's decrease in operating income was disproportionately larger than the decrease in revenue. The most significant effects on margin came from the less favorable product mix, manufacturing and transportation costs for several days due to winter storms and the lower unit volume.
I'll now turn to Slide #7 titled 2014 Financial Guidance. We are reaffirming the full year guidance that we previously issued on February 20. Despite our miss to the guidance in the first quarter, we continue to expect our results will improve over 2013 in the range as shown on Slide 7. Underscoring our continuing confidence is our belief that residential end markets will lead the 2014 recovery, a stronger recovery for Gibraltar than we expected at our last earnings call based on improving order rates through April.
For the Residential Products segment, the latest industry indices, such as the National Association of Home Builders Housing Market Index, Harvard's Joint Center for Housing Studies' Leading Indicator of Remodeling Activity as well as the latest Census Bureau reports on housing starts and sales still points toward a gradually improving market for new construction and remodeling in 2014 despite the weak first quarter. While reroofing demand correlates to repair and remodeling activity, that is also expected to provide modest single-digit growth for all of 2014. With seasonally favorable weather approaching, we expect demand to return as well as recover the weather-related order delays from the first quarter. Additionally, we have customer programs incremental to last year that have produced initial success. And most importantly, as cited in our earnings press release, we had notable improvement in incoming order rates.
A stronger upside for our Residential Products this year could offset any unexpected weakness in the second half demand for our Industrial & Infrastructure Products. And continuing with Residential Products, our expectations are for this segment to grow in 2014 by 10%. And this 10% sales growth is based on sustained residential new construction, modest growth in residential remodeling activity plus the rising demand for our postal and parcel products.
Regarding the notable increase in order rates through April, a large proportion was for postal and parcel delivery products. We believe these higher order rates result from a range of customer initiatives, including the promotion of centralized mail delivery. Because centralized mail delivery is the most cost-effective, efficient and secure method of delivering mail and packages to postal customers, the demand for centralized delivery equipment continues to grow. And our Florence manufacturing business, a recognized leader in the design and manufacture of secure multicompartment mail and package receptacles for centralized deliveries, has been developing new product initiatives to serve this growing demand. It has a very long history of serving the U.S. Postal Service as well as private owners of residential and commercial property in converting single-point deliveries to centralized delivery. And Florence's new product initiatives involve mail and package delivery receptacles targeted to lower the cost of delivery, increase security for the contents and benefit customers' greater convenience. And we expect 2014 to benefit from higher sales of these parcel and postal delivery products.
In our Industrial & Infrastructure Products segment, we saw less volatility in industrial demand and pricing during the first quarter than we experienced in prior quarters. And although certain macros, such as the ABI, fell below 50 in March, other indicators, such as the PMI index, increased in March. And economic forecast for Europe, which we also have penetration for industrial products, points to GDP growth after recent periods of contraction. After a slow start to 2014, we are expecting modest growth for our products serving industrial end markets. And as previously cited, we expect growth from end markets, such as manufacturing, mining and power generation. Oil and gas projects involving terminals, including pipelines, are also expected to increase this year, driven by intensified horizontal drilling.
Supporting our expectations for growth for industrial products was our improving quotation volume for applications of grating and expanded and perforated metal, which increased 50% in Q1 over Q4, as well as higher quoting and as well as incoming order rates in April. The general feeling among our industrial distributors is that 2014 will be better than last year with weighting in the second half. And improved demand from industrial markets should help ease some of the pricing pressure. These qualitative factors lead us to expect modest industrial-related revenue growth in the low single-digits for 2014 as a whole.
Also this segment sells products to the transportation infrastructure market, and this market is affected by the current uncertainty for federal government spending on transportation. The current 2-year federal transportation appropriation expires this coming September 30. While there's growing dialogue regarding the new bill at the federal level, including how to raise new sources of revenue, state and local governments are embracing the idea of coming up with funding sources of their own, and several have. In the meantime, a narrowing window of current federal funding for new projects has led to projects of shorter duration and smaller dollar amounts and have contributed to our lower backlog of transportation projects currently. As a result, our first half 2014 revenues and profits for transportation infrastructure products are expected to be unfavorable compared to the strong first half of 2013. We are focused on capturing our share of bids and growing our backlog. This should position us for a stronger second half of 2014 with the potential for upside when Congress approves a new appropriation bill for transportation spending and states continue to generate and allocate for projects based on funding they've generated locally.
Regarding our unallocated corporate expenses for the full year 2014, we expect it to approximate $18 million or 2% of sales. And adjusted net interest expense is likely to approximate $15 million for the year with an adjusted tax rate for the company of about 38%. As a result, we continue to expect Gibraltar to deliver sales growth between 4% and 7% this year, led by momentum in residential demand while increases in demand for our Industrial & Infrastructure Products are expected to be weighted toward the second half of the year and be in modest single-digit growth for the full year. And regarding expected adjusted earnings for 2014, we expect to be in the range of $0.76 to $0.90 per share, which compares to the $0.69 adjusted for 2013. Longer term, Gibraltar is well positioned to deliver more significant improvement on both the top and bottom lines as a more broad-based end-market recovery occurs.
Now I'd like to turn to Slide #8 titled the Second Quarter 2014 Preview. The second quarter is historically 1 of the 2 quarters each year with the highest order volume and revenues as warm weather construction activity gets into full swing. As previously stated, April order rates are encouraging for both segments. In Residential Products, the help of April's incoming order rates is expected to contribute to the segment's sales growth shown on the slide. In our Infrastructure & Industrial Products segment, its April order rates for larger-sized fabricated projects using bar grating and expanded metal nearly doubled the monthly average while, however, their scheduled delivery dates are weighted into the latter part of 2014 and early part of 2015. Concerning adjusted earnings, we expect the second quarter of 2014 to be between $0.29 and $0.32, benefiting from delayed orders from Q1, seasonal demand from residential construction activity and industrial markets and the incremental shipments of postal products.
And at this point, I'll turn the call back to Brian.
