"Awesome Contractor — Fair Pricing & Quality Workmanship Geno's Siding & Roofing Company replaced my gable vent today. It was the first time that I used this company, and I will absolutely use them again. I am retired, so I watched the entire project and was amazed at how skilled and meticulous the worker (actually the owner) was. The next time I encounter something that I can’t personally fix, I am calling Geno's Siding & Roofing Company at 215-971-6292. Howard (Howie) Walters Langhorne, PA"

"Myself and my father has used MJA Contracting for two roofs in our houses in Jersey City. Both times Manuel and his team has taken good care of us and installed good roofs. At first I thought the price was a bit high but after I saw the amount of time, material, and workmanship that they completed I thought the price was very fair. Roofs are alot of work as I learned. What I especially liked about Manuel is he did not go cheap and install a torch down rubber roof. He installed a rubber EPDM roof instead. If you have a flat roof, do yourself a favor and install a rubber EPDM membrane and make sure to contact Manuel. He also rebuilt our chimneys very good as well. Excellent masons! I guarantee you will not be disappointed!"

"Great company to work with! So professional from beginning to end of the job. We had a slate-look shingle installed on our historic house (1850) and a flat roof replaced on the rear section of the house. Both look awesome. Clean up was excellent!"

"Luis and his crew did a great job replacing a flat roof along with part of the main roof. This was a big job that was very well done in good time. Meticulous workmanship in every aspect of the job at reasonable costs and Luis was always easy to reach. I will certainly be using and highly recommend Economic Pro Construction"

"Janucz was on time, friendly, professional and worked hard to make sure I was happy. HOWEVER, upon installation of my tile kitchen backsplash, the workers were found standing on my stove top, used my garbage can as their mixing bucket (which Janucz ran out and purchased a new one for me) and chipped several tiles. It took far longer than expected too. I would be weary of recommending them if I knew I couldn't be around to supervise the job like a hound. If it were Janucz doing the job, I would trust him implicitly. He was respectful and meticulous. His workers, not so much."

"I hired BH Builder to replace a window with a sliding door and build a new deck. Anthony coordinated the entire project flawlessly from start to finish with zero issues. The quality is excellent and the results are fantastic. Highly recommended — I’ll definitely use them again!"

"I needed my chimney repaired along with my roof. They did a phenomenal job. They finished my roof in one day and finished the rest the next day even during a not so cooperative weather. Frank and Vinny answered all my questions and explained in detail what was being done. Overall I would give them a solid recommendation."

FAQs for flat, foam, or single ply roofing installation and replacement projects in Lambertville, NJ

Many roofing pros point to PVC as the top performer on flat roofs thanks to its tough seams and long-term waterproofing. A properly installed PVC membrane can last 30 years or more, resisting ponding water and harsh weather with ease. You will pay more up front than you would for EPDM, but the added durability often translates into fewer repairs and a lower cost per year of service.

Yes, a rubber roof is an environmentally friendly choice. Most rubber membranes contain recycled content and can reflect heat, which helps trim cooling bills in hot weather. Manufacturing has a lighter footprint than many traditional materials, and the long lifespan means fewer tear-offs headed to the landfill. If sustainability is a priority, ask your roofer about brands that carry third-party eco-certifications and confirm they meet local environmental standards.
