"The team at Avstep were amazing. So friendly and helpful. They replaced our garage roof and helped us with joist work. They were right on time, were super efficient, and organized and cleaned as they were working. It was so nice to talk with them and were very upfront and honest. The whole job was explained in professional detail and gave us a quote for the job that we felt was very fair. The work started the next day and was completed in a day and a half. They are worth more than a simple 5 star. We will now be using them for the added work we are planning. You won’t be disappointed."

"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."

FAQs for addition to existing structure building service projects in Dayton, 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.
