Commercial Roofing Systems and Workmanship

There are two choices to make when the time has come to replace your roof: the roof system and the installation team.


The key factor in selecting a roof system is not what the roof costs initially, but what the annual cost will be to own and maintain the roof during it’s service life. Paying more for a system that will perform long term, with little or no maintenance costs, will prove to be a better purchase than selecting a cheaper system with a shorter service life and high annual maintenance costs. Annual cost over service life is the key.


The best flat roof system, metal roof system or low sloped system in the world will perform poorly if improperly installed. Many things can go right or wrong during a roof installation. Sentry specializes in re-roofing businesses, schools, plants and facilities of all types that are fully staffed and in operation.
