"Saw this guy driving on the highway with some serious road rage. Purposely swerving into another car and blocking them when they tried to pass. I wouldn't hire someone who loses their head that easily"

"Bob and his crew are the best. This was a major renovation and complete re-do of a split level house that we converted to a more traditional house. 95% of our house was redone. Bob is meticulous and his subcontractors are fantastic at their crafts and very loyal to Bob for good reason. He was pretty instantaneous in his communication with me even on weekends, which we rarely bothered him in. This was a mid 6 figure job that Bob said would take 4 1/2 to 6 months. They finished in 5 1/2 months which is pretty amazing during a pandemic with major supply chain issues. Bobs bid wasnâ t the lowest, but it wasnâ t the highest of the 5 bids we received. They were pretty much on budget except for material price increases, especially lumber which was not his or the lumber yards fault. If youâ re thinking of hiring MZ Development you will not go wrong if you hire them to do whatever size project you are thinking about."

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