"Elliot was great! He responded promptly to my initial request and came to my house shortly after to assess the project. That same evening he emailed me a very reasonable estimate. A few days later the project was complete. Communication was solid throughout the process, and I am very pleased with the quality of the build. We will cheerfully hire his services again in the very near future."

"I contacted John on a Saturday, and he was able to come out the next day on Sunday morning. I had purchased the doors, and he ripped out the old doors and replaced with new ones. He took care of the casing as well. I was pleased with the work, the price, and John's just easy to work with as well. Very nice gentleman."

FAQs for addition to existing structure building service projects in Janesville, WI

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.
