Dear Sir,Two years ago, we called on your professional services to remedy the problems we were experiencing on our Service Building roof. We had ice forming on the roof causing water to run inside the building over top expensive equipment, and also high voltage control cabinets. Another factor that made us approach your company was the fact that fair size ice formations had already come down the roof and could have caused bodily injuries to employees working at this station. Since your company has insulated our roof with your Foam Roofing System, three problems were totally eliminated: water leaking on equipment, ice formation on the roof and heat loss. It is my belief that the money saved in heating costs paid the repair of that roof the very same year. Thank you very much for a job well done!
