"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!"

"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."

"Wow! I had the privilege of Bailey helping me with a project to build a pantry and I can’t express how impressed I am with his dedication and craftsmanship. He worked SO hard, all day long, and finished the entire thing in record time. All while having innovated ideas to make the project extremely functional and professional. His craftsmanship was outstanding and his work ethic was the cherry on top. I hope to work with him again soon."

"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!"

"Lionsgate is the best!!!! As first time homeowners, we had spent several months looking for the best contractor to help with our basement remodel-- and we are so happy that we found Alex, Gina, Sam, and the entire LionsGate team. Some qualities that made them the ideal partner for the job: ⁃ They worked within our budget without sacrificing quality ⁃ Alex navigated the convuluted permitting process way more effectively than we ever could have (and likely other contractors may have given up on some aspects of the job) ⁃ They continuously checked in to make sure the finished project matched our vision. No detail was too small ⁃ LionsGate works with a team of top tier electricians, plumbers, tile designers, etc. which made the entire process seamless. We could rest easy knowing every aspect of the job was covered by vetted professionals, without needing to find them ourselves. The final product is a basement which is stylish, modern, and livable. It truly exceeded expectations!"

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