"Francisco Garcia did an excellent job finishing our basement. The work quality is excellent. The communication and flexibility throughout the project was excellent. The project finished on time within budget with zero surprises. Any concerns that arose were addressed expeditiously and professionally. I highly recommend Colorado Paradise Builders for your next project. The building inspections were coordinated by Colorado Paradise Builders and passed easily. We learned while talking to the inspectors that we had a gift by using Francisco as a general contractor. They mentioned other people in the business may not provide the level of customer service and professionalism which Colorado Paradise Builders demonstrated on our basement finishing project. I could not be more enthusiastic with a recommendation."

"I hired Paramount back in 2020 for work on the first floor and appreciated their work so much that I brought them back for the basement (fix/ update after mold repair) and second floor (bathroom and stairs update, new carpet). Like the first time, I really appreciated Ryan's suggestions on style and options, and the various contractors were professional and very kind about working around me and the cats. Ryan was ultimately more critical than me about details and appreciate that desire to do things right and as clean as possible. Would use again!... although that would require a new house at this point. 😁"

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