NEW FLAT ROOF CONSTRUCTION & REPAIRS IN NEW YORK For decades, Goldenberg Roofing NYC has been providing residents of the five boroughs of New York City with the highest rated and most efficient flat roofing services. Our new state-of-the art flat roofing systems are aesthetically pleasing, reduce heating /cooling costs and keep your building structurally sound. Goldenberg flat roofing systems will add a significant amount of value to your residential or commercial structure by keeping mold, mildew and moisture away from your property. Patching up antiquated flat roofing will cost you more in the long run and keep your roof at a risk for major damage. Over the years, many of our clients went with the patch and repair approach and within a few years time were forced to purchase a new flat roof (regretting the fact they could have enjoyed that same new roof for many years prior).
