The renovation of Soldiers & Sailors Memorial Hall & Museum’s terrace-level roof increases the insulation value, corrects moisture infiltration issues, enhances aesthetics and incorporates green technologies as part of a masterplan to update the historic facility. Through careful investigation, we discovered that stormwater was backing up through the rain water leaders causing damage to interior ornate plaster work throughout exhibit space. Estimates to correct this ailment were in the tens of thousands. To preserve aesthetics and save money, we instead addressed the problem from the exterior by removing 3’x3’ sections of concrete roof deck at each drain, creating access for new, water-tight connections and avoiding wholesale demolition of the interior plaster.
Moreover, the addition of a green roof reduced the quantity and rate of water being put into the stormwater system, further reducing the likelihood of system back-up. The vegetated system covers 54% of the roof, making it one of the largest in Pittsburgh!
