When used, flashing must be installed in the correct areas and fastened properly. If all steps prescribed by the manufacturer are not followed, the life expectancy of the roof may be compromised.

Neglect
Like any building component, a flat roof needs regular maintenance to prolong its life. Flat roofs should be inspected regularly and minor issues fixed promptly. It is also important that the correct materials be used when making these repairs. For example, you should not use plastic roof cement to repair a single-ply
