"American Home replaced my roof and siding, porch windows and some add-on exterior lighting. One of the reasons I chose AHR was not just due to the best price, they came in line with other estimates I received, but because they included things with their final price that similar companies had as add-ons at an extra cost such as the dumpster and gutter system. I did not know what to expect as this was the first time I've had these things replaced. My rep John was awesome, he was professional, friendly and accommodating, and was able to work with me on the spot vs. "I have to check back to the owners" which I got from other companies. John was readily available by phone, text, and in person. He walked me through all the steps, timelines, and the whole process. After the crew finished, he took my list of 'nit-pick' things and made sure they were addressed. Overall I am satisfied with the job, In fact, we recommended them to our neighbors who hired them to do their siding this Spring."

"All-Star Contractors was a pleasure to work with on my garage project. Bill scheduled an assessment and was right on time, during which he provided a competitive estimate for the whole project. The garage included electric, cement, roofing, and custom shelves, all of which Bill and his team were able to provide. His team showed up on time every morning and got the work done on the agreed-upon timeline. Bill was easy to work with an accommodated several special requests and his team did a fantastic job on the project. I would hire him again for any construction or home improvement needs!"

"Exceptional Work and Professionalism Justin from Innozign Contracting did an outstanding job building a bathroom in my mother’s home. He is professional, detail-oriented, and committed to high-quality work. From the start, he listened carefully, created a solid schedule, and stuck to it while ensuring everything was done to perfection. His kindness, patience, and adaptability shined through as he worked with my mom to complete the job, making the process smooth and stress-free. The finished bathroom looks fantastic, and I highly recommend Innozign Contracting to anyone looking for a skilled and reliable contractor! "

"We hired Carlos Herrera of Rioza Construction in Feb 2024 for a major renovation and second-story addition under a Fannie Mae 203K loan. The home was move-in ready?just small for our family. Now it?s severely damaged from partial excavation, demo, and unnecessary removal of molding and walls. After a year-long variance process, in October of 2025 we were ready to build, Rioza demanded an extra $40K for ?inflation.? We asked for an accounting of the $84K advanced for materials?none provided. Quotes passed off as receipts were confirmed fraudulent by suppliers. No materials delivered, no phases completed, and we failed foundation inspection. HUD consultant documented everything; bank refused to release additional funds to Rioza Construction. Work has stalled for 6+ weeks, contractor name on Home Improvement license not Carlos Herrera's, belongs to someone we?ve never met. BUYERS BEWARE: Do NOT hire Rioza Construction. Verify licenses, demand receipts, and proceed with extreme caution."

Customers say: Quick response

"I recently had the pleasure of working with MF Builders on a home addition, kitchen remodeling, and bathroom remodeling project, and I am beyond thrilled with the results! From the very beginning, their team was professional, communicative, and truly took the time to understand my vision for the space. The home addition turned out better than I could have imagined, seamlessly blending with the existing structure while adding much-needed space and functionality. The kitchen remodel completely transformed the heart of my home. It now feels open, modern, and incredibly efficient. The attention to detail in the cabinetry, countertops, and lighting really made a difference. As for the bathroom, it went from outdated to absolutely luxurious. The design was both practical and stylish, with quality finishes and fixtures that made it feel like a spa. Throughout the process, the MF Builders team was respectful of my space, kept the work area tidy, and always made sure I was satisfied with each step. What really stood out was their commitment to meeting deadlines and staying within budget. They provided regular updates and were always open to any questions or concerns I had. I am so happy with the final outcome and highly recommend MF Builders to anyone looking to renovate or expand their home. They exceeded my expectations in every way!"

FAQs for addition to existing structure building service projects in Somerville, NJ

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
