"This was a huge effort, especially with working through Jefferson County permitting processes. They worked with architect, engineer, soil, surveyor, and then did an amazing job on the construction. They found phenomenal matches to existing materials, including fireproof wood siding to match existing. The finish work, especially Tile and cabinet install were phenomenal."

"We hired Chris at Prospect 30 Eight to build an addition on our house for my aging mom. It was a scary commitment for us, and Chris made it manageable. He handled every step of the process, from design and permitting, to hiring and managing the flow of workers, and all the steps of the building process, right down to the small details. Chris is honest, trustworthy, and a hands-on guy -- he will drop everything and show up if something is wrong. He has a calm demeanor and will figure out a solution to any problems that come up. I am so grateful we found him for this project. The end result is exactly what we wanted and better than we could have imagined. It has been a pleasure spending time with Chris. Highest recommendations!"

"Highly recommend Rich Madura and his team! High-end 1250sf basement addition started in July 2024 and completed 1st week of November, took 4mo, just as promised. Very good communicator through-out the process and he even provided material samples for flooring, countertop and tiles to help with the finish work."

He consistently stood behind his commitment to the timeframe, completing the work as promised without compromising quality. His professionalism and dedication made the entire renovation smoother than I had anticipated. I would definitely work with Verified Builders again and strongly recommend they services to anyone looking to improve their home"

FAQs for addition to existing structure building service projects in Centennial, CO

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.
