Cerrudo Services provided approximately 6,800 SF roof patching at failing areas of roof at Buildings 50 and 51. A pre-construction walkthrough was performed to identify existing patch locations noted in the RFP as well as any additional areas requiring repair. This site visit identified the material loading areas for each building, the material lay-down area and the debris box location.
The roof deck was be prepared by pressure washing the existing surface areas for repair at tie-in locations. The surface was allowed to dry thoroughly. Blister areas were cut out to expose the BUR roof membrane surface. The roof membrane remained in place. The repair areas were primed with silicone primer at a rate of 400-600 SF per gallon, per manufacturer’s specifications. The primer was allowed to dry thoroughly. Butter grade silicone roof sealer was applied at cut edges and reinforcement fabric embedded into sealer. Silicone coating was roller applied at patch areas at a rate of 2.5 gallons per square. The roof patching was warranted for five years.
