Roof Maintenance
It is prudent for the building owner to have routine roof maintenance performed on the roof at a minimum of once a year, preferably two times a year — spring and fall. Koppers warranted flashings (Specifications #172, #176 and #180) must be coated every 5 years with Koppers Aluminum Coatings.

Routine roof maintenance including both roof membrane and flashings is recommended regardless of whether or not the roof is warranted.

Koppers has a complete line of roof maintenance products to assist in this area. For more information on Roof Maintenance Product and Systems consult your local Koppers representative. Koppers has developed a comprehensive Roof Repair Handbook describing various roof maintenance procedures. This handbook is available from your Koppers representative.
