Grandmark Service Company specializes in providing complete roofing, air conditioning and energy saving projects. The company was started by two brothers, who were experts in the industry, and saw the need for companies to provide all of the installation needs without having to subcontract out jobs. The company also exists because during installations something would not be completed satisfactorily and they wanted to fix this problem with their unique business model.

Fresno Roofing Contractors


  • I recently used Grandmark Service Company for a roofing repair project and new ductwork for my central air and heat unit. Two new solar light tubes and two exterior roofing vents for my whole house fan. First Grandmark was quick in sending out a Technologist to assess my roofing repair. The repair was done in a very professional manner with special attention paid to a down spout. I can't thank that tech enough for the excellent work and attention to detail. I then decided upon inspection of my existing ductwork to have it replaced. Again, the crew removed all the old ductwork out the top of the attic where the new exterior vents would be placed saving me a ton of clean up. Throughout this process they provided tarps on the floor and did a thorough clean up at the end of the day's work. All crew member's were professional and friendly and answered any questions. If I could I would give them ten stars. But for this review five stars will have to do. Again, thank you Grandmark service company. I won't hesitate to use you again should the need arrive.

    Recently moved to the central valley, got 3 quotes from other companies that were way over priced. They finished the job in less than two weeks. Highly recommend this crew..will be using them for solar install in the future
