I contacted Zenith Engineers near the end of a long and painful roof deck project, after multiple other engineers had flaked or provided incorrect information (or both). From the beginning, everyone I worked with at Zenith was helpful and responsive. They were clear about what needed to be done, how they would do it, and how much it would cost. With their help I was finally able to do what the city had been asking for and get our project approved. I will definitely use them for any project in the future and cannot recommend them enough for anyone else in need of engineers.
