Pittsburgh had a hell of a winter storm in January, with more than a foot of snow, and freezing temperatures that created towering walls of ice and annoyed locals whose parking situations wouldn’t return to normal for a month. Some of the city’s oldest buildings suffered the most damage, victims of a phenomenon known as ice damming. The warmth from a building rises to the snow banks on the roof, but it’s only enough to defrost the bottommost layer, which then flows to the eaves and then re-freezes, creating a trapped reservoir of snowmelt that penetrates cracks and crevices, and flows into the walls to create conditions for mold. Ice damming alone caused millions of dollars worth of damage in Pittsburgh, but perhaps nobody in the city felt as targeted by thermodynamics as Naomi Ruiz, a conservator currently working on some priceless and suddenly damp treasures at St. Nicholas Croatian Church.
“I had, like, just gotten back home [to Europe] when they sent me a picture,” she says, pointing up toward the corner of the Church’s arched ceiling. Even from down here, I could see the intersection of the balcony and the wall was stripped of paint and had the unmistakable flaky look of water damage. She sighs as she remembers the sinking feeling. “That was the spot I’d spent a bunch of time fixing just before leaving.”
Naomi specializes in the painstaking process of preserving art in aging churches. It’s much more complicated than simply putting a fresh layer of paint over the water damage or scrubbing candle soot from the walls. At St. Nicholas, Naomi is tasked with conserving internationally renowned—and uniquely provocative—murals painted by the Croatian artist Maxo Vanka.
