"I've used Mike and Cameron on a few of my remodel projects. Mike pays great attention to craftsmanship. When we ran into some technical complications with the remodel, he was able to solve the problem and keep the project moving. Very pleasant to work with. I will be using Techniques again in the future. Thanks again."

"I highly recommend A to Z Remodelers and will hire them again for my next job. Roman Chabin at A to Z remodelers did a wonderful job! Roman did everything that he said he could do. The crew was efficient and showed up on a timely basis and when they said they would. I was especially happy that Roman was able to deal with MetLife, my problematic insurance company, which was very difficult at best. A car had driven into my rental property and caused extensive damage to multiple rooms. Being a former contractor, city building inspector, Minnesota State Building Official number 1540, and currently owning a home inspection company, I have had experience with numerous contractors and insurance companies."

"We had Reetz Construction redo our existing deck. They did a wonderful job replacing the old wood with Armadillo composite decking. They had a great attention to detail and were meticulous about ensuring everything was just right. I highly recommend them!"

"Joe and his team did a fantastic job with our roof on our home and garage and did so on time and within our budget. Joe also completed some siding work that was in need of repair and went above and beyond to make sure we were completely satisfied. I highly recommend Joe to my family and friends for any exterior work that needs to be completed!"

FAQs for addition to existing structure building service projects in Chanhassen, MN

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.
