"I had the pleasure of working with Mike, a general contractor for my multi-unit investment property on the northwest side of Chicago. Mike demonstrated a strong vision for how to add value to the property, offering creative solutions (adding livable square footage to the attic unit for a duplex up) that made a significant impact. His attention to detail and ability to identify areas for improvement helped enhance the property's after rehab value, all while staying within budget. What stood out most was his excellent communication throughout the entire process—he was always available to address questions or concerns and kept me updated on progress (daily updates). His professionalism and efficiency were unmatched, making the project run smoothly from start to finish. I highly recommend him to anyone looking for a reliable, skilled, and thoughtful contractor."

FAQs for addition to existing structure building service projects in Chicago, IL

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.
