"We couldn’t be happier with our entire experience with Pete and Regal Construction from day 1 for our addition and remodel. We were so impressed with his communication and scheduling of subcontractors. Rarely was there a day that someone wasn’t at our house working to finish the project. The project finished a little early despite delays with permitting due to the city of Lakewood. The original estimate Pete provided was very close to the actual cost, however we added on several changes during the process. Pete was easy going, friendly and great to have around during the entire process. Would highly recommend!"

"Jason and his team are the best contractors I have worked with. I have lived in my home for 25 years and have remodeled and worked with other contractors so I have a pretty good foundation of how to plan my project, my vision and what I expect. Jason was incredibly helpful in the beginning when I showed him my plans and made suggestions that I would never have thought of. He actually picked out fixtures and the materials with me! His team is hardworking, professional and kind. I will be working with Jason in the future on additional updates and wish I found him before now because I had to ask him to re-do some of the work that was done by others. I highly recommend Odyssey Construction Group LLC!"

"Alan Gaul merged two back to back closets and turned it into s larger pantry. He removed and closed off the two existing doors and repositioned it on the kitchen side. He did an excellent job and made sure everything was perfect and cleaned up before he left. I highly recommend him."

"Hired Denver Construction to renovate the main level of my house including the kitchen and the bathroom upstairs and they did such an awesome job. Trusted them in my home while I had to work and came back to a job well done on multiple occasions. Highly recommend this company. Will be hiring again sometime in the future. Thanks DC!"

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