Whether it's new construction, a re-roof, repairs or service, Tri-State has been trusted by some of the largest companies in the country to take care of their roofing needs. Often times, national brands like these have very stringent safety and work requirements. This means that we need to be vetted for compliance long before we step on their roof. These brands often use companies like Avetta, ISN, Veriforce, ComplyWorks, ESFM, GSH and more to ensure that contractors on their premises will complete their scope in a manner which is safe and acceptable. Tri-State has been vetted by these companies to ensure that we can work on their roofs.
