Your investment in a waterproofing system should be based on selecting flat roofs, which are designed to be the best over the entire life cycle of the assembly (typically 20 plus years). Key to keeping replacement costs down and extending the life of flat roofs is to provide for periodic maintenance, especially on commercial roofing systems. This is true to all applications and types of Commercial Roofs.
