Re-Roofing Your Metal Roof
Duro-Last Roofing System

Normal problems of an aged metal roof:

  • Rust and corrosion
  • Loosening of screws due to continuous expansion
     and contraction
  • Deterioration of neoprene washers, sealants,
     and caulking
  • Loss of effectiveness of normal maintenance      procedures such as tightening screws, resealing,
     and recaulking
  • Gutter and drainage backups
  • And the inevitable rising tide of leaks
