Harold and Team made sure that the work was completed to my satisfaction. This seems to be rare nowadays. Highly recommended for any metal roof work! Glad that I found them using the HomeAdvisor
Very professional and prompt. Quality work and materials. Completed my job in one day. Went above and beyond other quotes on same job, for much less money. I am extremely pleased with this contractor.
Professional, fast and efficient. Harold was very personable and easy to work with. Did a great job!
Friendly owner, great price, roof looks great. Looking forward to seeing how the snow slides right off in the winter.
