Hearst Hall is the original main building of the National Cathedral School and was designed by Robert W. Gibson of New York in a French Chateau style. Since 2006 Wagner has worked with the school to restore the building’s roof and gutters in a phased fashion during the summers when the school is out of session. The extensive copper work that Wagner performed in its restoration brought highly-detailed beauty and craftsmanship back to the building’s historic Vermont slate roof. Four circular copper dormer windows, cladding, valleys, pipe collars and built-in copper gutters were all replaced with custom fabrications to match the original design and were reinstalled in accordance with SMACNA & NRCA historic guidelines. Repairs were also made to existing concrete substrate, along with major carpentry repairs, to restore the elements to their original condition.
