"Working with Gabriel and American Family Construction & Remodeling was probably the least stressful part of our entire home upgrade journey From the first meeting, Gabriel was incredibly organized and had a clear plan of action. He listened to what we wanted, offered smart suggestions, and worked with our budget without making us feel like we were cutting corners. One of my biggest fears was living in a construction zone for months ? but these guys worked efficiently and kept everything surprisingly tidy along the way. I really appreciated how Gabriel checked in regularly to make sure we were happy with each stage of the work Now that it?s finished, I can honestly say our new kitchen is my favorite part of the house. It's not just beautiful, it's practical and feels like "us." Thank you, Gabriel and crew!!"

"TERRIBLE experience. Complete lack of supervision of subs, shoddy workmanship in many many areas; refused to correct at his own expense his subcontractors installation of pocket doors, where the sub incorrectly modified the factory-supplied frame assemblies. Complete incompetence and complete failure to take responsibility for any work he arranged."

FAQs for addition to existing structure building service projects in Laguna Hills, CA

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.
