Roofs have to get repaired. It's just part of regular maintenance. In an imperfect world with an imperfect climate and imperfect materials, roofs age naturally and require maintenance and repairs to maintain their strength and integrity. An old shingle roof might get a loose shingle from a little wind, a crack might form in the seal of your commercial roof. Regardless of the cause, repair and maintenance is part of getting your money's worth from a roof installation, and having a professional do it right will not only save you big money in the long run, but it will also give you many more years with that roof.
