I didn’t even notice the black stains on the roof at the dealership here at Lynne’s Nissan West In Stanhope NJ that is until Barb had stopped in to explain what it was, and how many life years I was losing on my roof shingles. It was explained in detail what all of those stains, and growths were doing to my roof, and how those ugly stains are not only creating damage to the roof shingles, but the appearance of a car dealership says a lot about the reflection inside on how its ran. The funny thing is that most of the sales people, service technicians, and managers knew how ugly the stains were, and that they could be seen from Lackawanna Ave. and no one said anything! I immediately had Roof Renew Pros take care of the roof shingles, the before and after were amazing! Not only did I save thousands of dollars on not replacing the roof, but the building looks amazing! Now, the outside looks just as amazing as the inside, clean, and presentable, I would hire Roof Renew Pros to clean anything at our dealerships. Very knowledgeable, friendly, and professional. The prices were very fair and reasonable for the amount I would have been spending to replace the entire roof!
