"Jim (owner of Emerald Remodeling) came up with a great visual of what our garage add-on addition project would look like that none of the other contractors we solicited provided. As the project progressed, Jim kept us appraised as to what would happen and when to expect start and finish of each phase (cement work, framing, roofing & siding). No issues with the subcontractors for each phase. Jim returned our calls or text messages in a timely manner and paid us a follow-up visit a week after project was completed."

"I will definitely recommend Tyler. Being this was his first complete pole barn build, it turned out excellent. 36' x 63' x 14' high. I had set the poles previously and discovered that my math is not as good as it used to be. I helped some but we had to reset the posts, and everything was down to 1/16". It really made a difference when it came time to build the barn. Very trustworthy and always came out when he said he would. Top tier carpenter you won't regret!"

"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!"

"Atreas was amazing to work with! Extremely flexible and communicative! They removed a half banister wall in my kitchen (drywall on top, banister on the bottom) and replaced it. They framed and finished the wall beautifully and I love the result! It's exactly what I wanted and looks great, thank you so much!!!"

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