"If you want a competent, professional and courteous crew that will complete your project accurately, on-time and on-budget, call M&J Home Improvements! My 94 year old mother needed a bathroom overhaul to convert her bath tub to a shower stall equipped with handicap bars. We visited three of the larger well-advertised bathroom remodelers. One was temporarily closed, another was not helpful and the third was way over our budget. We found M&J Home Improvements of S.A. on Angie’s List. M&J had great reviews so we called Michael Moreno for a quote. Michael was knowledgeable, friendly and offered an overhaul that worked with my mom’s budget. Michael provided a complete bathroom overhaul…he re-leveled the bathroom floor, installed drywall, removed the existing tub and shower walls and installed new shower walls, installed a new vanity, painted the entire bathroom, etc. Michael and his staff were prompt, friendly and professional through and through. Michael was easy to communicate with from start to finish – he listened to our concerns and answered all of our questions and came up with solutions. He and his team did an outstanding job and worked diligently to finish our bathroom overhaul in a week. They worked every day until the job was completely finished. We are very happy with my mom’s new bathroom and highly recommend M&J Home Improvements!"

"I have hired Bill Clark on two different occasions to replace my roof due to hail damage. I can truly say that any time I need a roof done I'll call Bill. He does the job right the first time. I trust Bill with all my roofing projects 100%. I have never had any problems with the roofs he has put on my home. I can rely that the job is done right the first time."

FAQs for addition to existing structure building service projects in Karnes City, TX

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.
