Safety is a top priority for Sentry – it’s the first thing I see at the job site. Making sure everything’s well marked off, roped off where it needs to be, everyone is where they need to be, all the lifting and hoisting is done properly, the roof is very clean at the job site no tools and clutter laying around. Everything’s in its proper place all the time.
