Roof repair and replacement.
Most of our reviews are about roofs, and many of them mention the same two things: how quickly the job was done, and the price. Roofing in Bergen County.
“Make your life easy - just hire Robert Johannemann & Sons for your new roof … His quote was the best one we got; and just a week after we met, my new roof was completely done. His professionalism is exceptional, there was no pressure to do more work than I thought my old house needed; the final bill was exactly what we agreed upon. … thousands of pounds of shingles are NOT thrown down to CRUSH your landscape and lawn.”
“Rob and his team were great - they took the time to explain what they had to do and why, and his prices were low compared to other quotes I received in the area. I would definitely recommend to others for replacing their roofs in Northern NJ.”
