Preserve, Protect and Defend

Our thoughts about government get intertwined with our images of the buildings that house its institutions. Architects know this, and in their designs, they often strive to evoke the key principles governments aspire to—permanence, stolidity, common-sense functionality, even grandeur. These buildings can touch our emotions. They can inspire us.

But no building lasts forever. When the time comes, talented individuals and enterprising companies have to step up and secure the integrity of these landmarks so they can survive to serve and inspire future generations.

The twin themes of this issue are government projects and historic renovation. Many of the projects you’ll see detailed on these pages would qualify in both categories, including three buildings that recently had iconic structures at their peaks meticulously restored. They include the copper pyramids on the North Carolina Legislative Building in Raleigh, North Carolina; the Saskatchewan Legislative Dome in Regina, Saskatchewan; and the Bradford County Courthouse Dome in Towanda, Pennsylvania.

The contractors involved in these projects conveyed the sense of responsibility that comes with keeping these one-of-a-kind structures functioning. But as they talked about the challenges they faced on these projects, it was the love of their jobs that kept coming through.

“We’re using natural, traditional building materials of stone, wood, copper and other noble metals,” said Philip Hoad of Empire Restoration Inc. in Scarborough, Ontario, as we talked about the Saskatchewan Dome project. “That’s what drives me to love the industry and my job—because it’s permanent, sustainable and it’s for future generations.”

Mike Tenoever of Century Slate in Durham, North Carolina, echoed that message when he talked about his company’s work on the North Carolina Legislative Building. “Our guys do this every single day, day in and day out,” he said. “It’s repetition, practice and love of restoration. Taking something so amazing and restoring it to the beauty it originally had—we all get a kick out of that.”

“You put in a hard day’s work and you’re proud to go home and know that what you’ve done is going to last not only your lifetime, but probably your kids’ lifetime, and maybe even your grandkids’ lifetime,” said Bill Burge of Charles F. Evans Roofing Company Inc. in Elmira, New York, as he detailed his company’s work on the Bradford County Courthouse.

Each of the roofing professionals I spoke with about these projects had the conscious goal of making sure the systems they installed might last another century. “We try to think of these slate and metal projects in terms of 100 years—that’s why we named our company Century Slate,” said Tenoever.

“This is the one thing that makes Charles F. Evans Company special to me: the fact that what we do from an architectural sheet metal standpoint, from a slate, copper, tile roof standpoint—these roofs will last 100, 150 years, and it is artwork,” Burge said.

“At the end of the day, why do we go to cities?” Hoad asked me. “We go to cities to look at their beautiful old buildings. We don’t generally go to look at their skyscrapers. It’s the old building that gets our minds and hearts working. When you go to a city and look at these old buildings intermingled with new buildings—that’s what gives a city life.”

Historic 1883 Barn Gets New Composite Slate Roof

This timber-framed Standard Pennsylvania-style barn was originally erected in 1883. When its slate roof deteriorated beyond repair, it was replaced with a synthetic slate roof manufactured by DaVinci Roofscapes and installed by Absolute Roofing.

Back in 1883, a timber-framed Standard Pennsylvania-style barn was constructed with a real slate roof on the homestead of the Hartong family, located in the City of Green, Ohio. After more than a century of service, the worn-out slate roof—and the rotting wood structural support system beneath it—have finally received a facelift.

“The structure was deteriorated beyond repair and had been leaking enough to also adversely affect the wood batten nailers,” says architect Chas Schreckenberger, AIA and principal of Braun & Steidl Architects. “Because this was a historic structure, our first choice was to replicate the original slate. When costs wouldn’t allow that, we investigated more economical slate alternatives.

“After reviewing all our choices, it was easy to make the selection of a DaVinci Roofscapes Single-Width composite slate roof. The appearance of the synthetic slate, its lightweight composition, affordability and durability all made it the obvious choice for this project.”

The next step required gaining approval on the roofing choice by the City of Green, which owns the structure, and the Ohio Historic Preservation Office, which awarded a grant to finance the roof’s replacement. Once approval was received, the project started. Christian & Son Inc. was brought in to replace the rotting timbers, and Absolute Roofing and Construction Inc. started the roof installation.

“The DaVinci slate tiles we specified enabled us to retain the historic character of the barn, even to the point of recreating the large ‘1883’ date on the roof,” says Schreckenberger. “The final outcome exceeded our expectations and everyone involved is extremely happy with the results.”

Roofer’s Perspective

The challenge of recreating the 1883 date on the roof, plus detailing the entire roofing job for the Hartong barn, required a great deal of collaboration between the team at Absolute Roofing and Braun & Steidl Architects. Started in the spring of 2016, from start to finish, the roof frame reconstruction and tile installation took about six months.

The 45-foot by 90-foot timber-framed barn is part of the Levi J. Hartong homestead, which was placed on the National Register of Historic Places in 2007.

“There were two significant challenges in this project,” says Chris Kamis, president of Absolute Roofing. “First, we were working alongside the framing team to make sure the structure was secure and ready for the roof installation. Second, we had to configure the 1883 date carefully.”

Recreating the numerals was a challenging task. “The DaVinci product was slightly different in dimension from the original slate, so it took several layouts to accurately recreate the date,” Kamis notes. “The original date on the roof had been very faded, so we had some guidelines. In the end, the roof looks terrific with the 1883 date in Evergreen tile colors showing up beautifully against the Slate Black tile background.”

The completed roof project received the Contractor of the Year Award from the National Association of the Remodeling Industry in 2016 in the commercial specialty category.

Reflective of the Pennsylvania German heritage of the Hartong family and the community in the 1880s, the 45-foot by 90-foot timber-framed barn rests on a tooled sandstone foundation. Finished with vertical wood boards, the barn is part of the Levi J. Hartong homestead that includes a farmhouse, summer kitchen, milk house and other outbuildings.

“The city purchased the property more than a decade ago and it was placed on the National Register of Historic Places in 2007,” says Sarah Haring, community development administrator for the City of Green in Ohio. “It’s located in the City of Green’s Southgate Park and since that time, the Summit County Mounted Unit has stabled their horses at the barn.

“The farmstead represents patterns in agriculture and architecture from the 19th century in our area. We’re excited to have the new roof overhead that so perfectly replicates what we believe the original roof looked like in 1883. The finished product is stunning and everyone, including visitors to the farmstead, are impressed with the look of the roof.”

Contemporary Materials Are Used to Preserve a Historically Significant 1889 House

In my capacity as a historic preservation contractor and consultant, I am often afforded the opportunity to become involved in exciting and challenging projects. Recently, my firm was awarded the contract to restore the clay tile roof turrets at Boston’s Longy School of Music’s Zabriskie House. Now part of Bard College, Longy School’s Zabriskie House is actually the historic Edwin H. Abbot House with a sympathetically designed addition built in the 1980s. The deteriorated condition of the original house’s turrets, as well as lead-coated copper gutter linings and masonry dormers, had attracted the attention of the Cambridge Historic Commission, and a commitment to the proper restoration of these systems was struck between the commission, building owner and a private donor.

The hipped roof turret on the building’s primary façade was in need of serious attention.

BUILDING HISTORY

Before I can specify historically appropriate treatments, I need to don my consultant’s cap and dig into the history of a building to best understand its evolution. Developing the background story will typically answer questions and fill in the blanks when examining traditional building systems. An 1890 newspaper clipping held by the Cambridge Historic Commission re- ports that “[t]he stately home of Mr. Abbot, with its walled-in grounds, on the site of the old Arsenal, promises to be the most costly private dwelling in the city.” An examination of records held by the Massachusetts Historical Commission and from the Library of Congress’ Historic American Buildings Survey reveals that the firm of Longfellow, Alden & Harlow designed the Richardsonian Romanesque portion of the building and that Norcross Brothers Contractors and Builders was the builder of record.

Alexander Wadsworth Longfellow Jr. (of Longfellow, Alden & Harlow) was the nephew of the famous poet Henry Wadsworth Longfellow and an important figure in U.S. architectural history. After graduating from Harvard University in 1876, he studied architecture at the Massachusetts Institute of Technology and the École des Beaux-Arts in Paris, after which he worked as a senior draftsman in Henry Hobson Richardson’s office. After Richardson’s death in 1886, Longfellow partnered with Frank Ellis Alden and Alfred Branch Harlow to found the firm of Longfellow, Alden & Harlow. With offices in Boston and Pittsburgh, the firm designed many important buildings, including the Carnegie Library in Pittsburgh and the City Hall in Cambridge.

Norcross Brothers Contractors and Builders was a prominent 19th century American construction company, especially noted for its work, mostly in stone, for the architectural firms of Henry Hobson Richardson and McKim, Mead & White. Much of the value of the Norcross Brothers to architectural firms derived from Orlando Norcross’ engineering skill. Although largely self- taught, he had developed the skills needed to solve the vast engineering problems brought to him by his clients. For example, the size of the dome at the Rhode Island Capitol was expanded very late in the design process, perhaps even after construction had begun, so that it would be larger than the one just completed by Cass Gilbert for the Minnesota Capitol. Norcross was able to execute the new design.

BUILDING STYLE

The Edwin Abbot House is an interesting interpretation of the Richardsonian Romanesque style. Whereas the great majority of such buildings feature rusticated, pink Milford granite in an ashlar pattern, trimmed with East Longmeadow brownstone, Longfellow created a unique spin for Mr. Abbot. Although the building is trimmed with brownstone, the field of the walls features coursed Weymouth granite of slightly varying heights. The motif of orange, brown and golden hues of the stone is continued in the brick wall surrounding the property.

Scaffolding was erected that would make the otherwise dangerous, heavy nature of the work safe and manageable.

Scaffolding was erected that would make the otherwise dangerous, heavy nature of the work safe and manageable.

The roof is covered in a flat, square orange-red clay tile. Richardsonian Romanesque buildings are almost exclusively roofed in clay tile; Monson black slate; Granville, N.Y., red slate; or some combination thereof. It should be noted that because their need for stone was outpacing the supply, Norcross Brothers eventually acquired its own quarries in Connecticut, Georgia, Maine, Massachusetts and New York.

The roof framing system of steel and terra-cotta blocks is relatively rare but makes perfect sense when considered in context with the latest flooring technologies of the era. A network of steel beams was bolted together to form the rafters, hips and ridges of the frame. Across each is welded rows of double angle irons (or inverted T beams). Within these channels, in beds of Portland cement, the terra-cotta block was laid. The tile was then fastened directly to the blocks with steel nails. Because of the ferrous nature of the fasteners, the normal passage of moisture vapor caused the nails to rust and expand slightly, anchoring them securely in place. Whether this element of the design was intentional or simply fortunate happenstance, the result made for a long-lasting roof.

What doesn’t last forever in traditional slate and clay tile roofing systems is the sheet-metal flashing assemblies. Over the years, there must have been numerous failures, which led to the decision to remove the clay tiles from the broad fields of the roof and replace them with red asphalt shingles in the 1980s. Confronted with the dilemma of securing the shingles to the terra-cotta substrate, a decision was made to sheathe the roof with plywood. Holes were punched through the blocks and toggles used to fasten the plywood to the roof. In an area where the asphalt shingles were removed, more than 50 percent of the plywood exhibited varying degrees of rot caused by the normal passage of vapor from the interior spaces.

Fortunately, the turrets had survived the renovations from 30 years before. A conical turret in the rear and an eight-sided hip-roofed turret on the north side needed only repairs which, while extensive, did not require addressing issues with the substrate. The 16-sided turret on the primary façade of the building was in poor condition. Over the years, prior “repairs” included the use of non-matching tiles, red roofing cement, tar, caulk and even red slate. A scaffold was erected to allow safe, unfettered access to the entire turret and the process of removing the tile began. Care was taken to conserve as many tiles as possible for use in repairing the previously described turrets.

As the clay-tile roof covering was removed, the materials of the substrate were revealed and conditions were assessed.

As the clay-tile roof covering was removed, the materials of the substrate were revealed and conditions were assessed.

The substrate was examined closely and, save for thousands of tiny craters created by the original nails, found to be sound. A new system had to be devised that could be attached to the terra-cotta blocks and allow for the replacement tiles to be securely fastened, as well as resist the damaging forces of escaping moisture vapor. Cement board, comprised of 90 percent Portland cement and ground sand, was fastened to the blocks with ceramic-coated masonry screws. The entire turret was then covered with a self-adhering membrane. The replacement tiles were carefully matched and sourced from a salvage deal- er in Illinois and secured with stain- less-steel fasteners. The flat tiles, no longer manufactured new, are referred to as “Cambridge” tiles for their prevalence on the roofs of great homes and institutional buildings in and around Cambridge.

CONTEMPORARY UPDATES

Although I typically advocate for the retainage of all historic fabric when preserving and restoring traditional building systems, there are exceptions. In the case of the Abbot House roof, we encountered “modern” technologies that pointed us toward contemporary means and methods. Rusting steel nails in the terra-cotta block were brilliant for initial installation but seemed ill conceived for a second-go-round. Instead, using non-ferrous fasteners and a new substrate that is impervious to moisture infiltration will guarantee the turret’s new service life for the next 125 years or more.

ROOF MATERIALS

Wagner Roofing was awarded the complete replacement of all roof systems. These included an upper double-lock standing-seam copper roof system, a bullnose copper cornice transition, slate mansard, 34 dormers with double-lock standing-seam copper and fascia metal, eight copper hip metal caps and a continuous built-in gutter with decorative copper fascia. Each of the dormers also had a copper window well.

The upper standing-seam roof was removed and replaced with 24-inch-wide, 20-ounce copper coil rollformed into 1-inch-high by 21-inch-wide continuous standing-seam panels that matched the original profile. The eave bullnose, which also served as the mansard flashing, was removed and returned to Wagner Roofing’s shop where it was replicated to match the exact size and profile.

The 34 dormer roofs were replaced with 20-inch-wide, 20-ounce copper coil formed into 1-inch-high by 17-inch- wide continuous standing-seam panels. The decorative ornate fascia of the dormers was carefully removed and Wagner’s skilled craftsmen used it as a template to develop the new two-piece copper cornice to which the roof panels locked. The cheeks and face of the dormers were also re-clad with custom-fabricated 20-ounce copper.

The oversized built-in-gutter at the base of the slate mansard was removed and replaced with a new 20-ounce copper liner custom-formed and soldered onsite. The replacement included a specialty “bull-nosed” drip edge at the base of the slate and an ornate, custom-formed fascia on the exterior of the built-in gutter. The decorative copper fascia included 85 “hubcaps”, 152 “half wheels” and 14 decorative pressed-copper miters. The original hubcap and half-wheel ornaments were broken down and patterns were replicated. Each ornamental piece was hand assembled from a pattern of 14 individual pieces of 20-ounce copper before being installed at their precise original location on the new fascia. The miters were made by six different molds, taken from the original worn pieces, to stamp the design into 20-ounce sheet copper.

In all, more than 43,000 pounds of 20-ounce copper was used on the project.

Maury Hall was built in 1907 and was designed by Ernest Flagg. Flagg designed many of the buildings at the U.S. Naval Academy, including the Chapel, Bancroft Hall, Mahan Hall, the superintendent’s residence and Sampson Hall. His career was largely influenced by his studies at École des Beaux-Arts, Paris. Examples of Flagg’s Beaux-Arts influence can be found in the decorative copper adorning the built-in gutter on building designs.

Maury Hall currently houses the departments of Weapons and Systems Engineering and Electrical Engineering. The building sits in a courtyard connected to Mahan Hall and across from its design twin, Sampson Hall.

Approximately 423 squares of 1/2-inch-thick, 18-inch-tall by random width Unfading Green Slates were installed by hand on the project. This was close to 750,000 pounds of slate, or 375 tons.

About 3,000 feet of custom copper gutters and downspouts, conductor heads and 100 squares of painted standing-seam panels were fabricated, and pre-built copper clad dormers and decorative copper cornices were installed.

The project also included 35 squares of copper standing-seam roofing, 25 squares of soldered copper flat-seam roofing and 115 squares of copper wall cladding. About 58,000 pounds of copper were installed on the brewery.

Everything on the building is oversized and that meant everything had to be built to support the heavy structural loads and live loads from wind and mountain snow. The large roof faces called for 10-inch custom copper gutters. When you have gutters that large in the mountains of North Carolina you have to consider the extraordinary weight of the annual snow.

In addition to snow guards being installed on the slate roof, custom 1/4-inch-thick copper gutter brackets fastened the gutter to the fascia. It is typical on steel-framed construction, particularly on this scale, that the framing is out of square and there is widely varying fascia and rake dimensions.

However, these items should not appear out of square or have varying dimensions. Great care had to be taken to measure and custom bend onsite all the detail flashings so everything appeared perfect. This took many skilled craftsmen, a great deal of time and the absolute drive to provide the highest quality work.

Carefully Select Roofing Materials to Maintain the Character of Historic Buildings

Selecting a historically appropriate roofing material is often restrictive as a simple matter of economy. Not everyone can afford a new slate roof. But individually landmarked structures and those in local historic districts are often monitored by historic district commissions (HDCs) that typically require property owners to replace in-kind or with an otherwise historically appropriate material.

Although the preference is replacement in-kind, an intelligent argument for an alternative can often be made. The HDC can consider other materials that were available at the time of construction, as well as what buildings of similar style in the community have on their roofs. A Queen Anne may have started with a polychromatic Vermont slate roof, but the commission can consider that nearby Queen Annes have monochromatic Monson slate or even cedar shingles. A Greek Revival may have a silver-coated tin roof, but few would argue with a homeowner willing to replace it with standing-seam copper. Let’s look at several American building styles and the materials used to roof them.

Colonial Styles, 1620 to 1780

From the New England Salt Box to the Dutch-vernacular homes of upstate New York, the earliest structures in the American colonies were roofed with wood shingles.

From the New England Salt Box to the Dutch-vernacular homes of upstate New York, the earliest structures in the American colonies were roofed with wood shingles. It is a myth they were covered with hand-split shakes because these sometimes do not hold up well. Wood shingles were easily made by planing down the shakes to a uniform thickness for ease of installation.

In the Northeast, Eastern white cedar was the typical material used while cypress was often used in the South. Western red cedar was not used much in the eastern U.S. until after the 1850s and should not be considered appropriate on a circa-1820, Federal-style structure in Connecticut. Eastern white cedar, however, rarely lasts longer than 10 years in a roofing application. Instead, preservation architects now specify Alaskan yellow cedar. Predominantly distributed from British Columbia, this dense wood is favored because of its longevity and because it develops a silvery patina, like Eastern white cedar, within one year.

Federal and Neoclassical Styles, 1780 to 1820

Many of these buildings have low-slope roofs and are often obstructed by a balustrade that runs across the top of the eaves. In congested, urban environments, the roof may not even be visible from the street. This raises the obvious question: What needs to be done when an element of the exterior is not within the street view? Most HDCs use that standard question to limit their purview over a proposed alteration. If your roof falls into this category, then you should pick the most enduring and sustainable material you can afford.

These structures were not often originally covered in slate, though many are today. Original roofs were wooden shingles—less than ideal on a roof with a shallow pitch. In limited instances, standing-seam or flat-lock-seamed roofs are seen on these building styles. To find out what’s appropriate, check out roofs on structures of the same style in your neighborhood and neighboring communities.

The mansard roof is the character-defining feature of the Second Empire style. A mansard is essentially a hipped gambrel. The lower roof, between the eaves and upper cornice, is most often covered in slate.

Greek Revival, 1820-50

This style also features a low-slope roof, typically 4:12. Although the original roof material may have been wooden shingles, many of these roofs in the Northeast were replaced by a more sustainable material long ago. Flat-lock tin or terne-coated steel were typical from the late 1800s on. Because many of these structures also have box gutters at the eaves, keep in mind that relining these systems is costly and will need to tie in to the new roof material. (See “Traditional Gutter Systems in North America”, March/April issue, page 56, or bit.ly/1Mw7Qek.) It is not uncommon for an affordable membrane, like EPDM or TPO, to be used on the majority of the roof while a costlier appropriate material, like copper, covers the visible, projecting “porch” roof.
