The roof decking was the next element to be installed after the stainless steel sheeting.  Evidence for the decking was found when a thin line of reddish paint was discovered on the brick walls of Montpelier's main block and was made when a painter accidentally brushed paint along the intersection of the deck and brick wall.  Incredibly, this accidental strip of paint not only recorded the existence of the decking but also provided its approximate height and the color it was painted.
