"We hired Topaz Remodeling and Yoni for a home addition to create a bigger living room and extra bedroom. The project involved framing, roofing, and major structural work - and Yoni handled it like a pro. He stayed on top of scheduling, inspections, und kept us updated every step of the way. The new space blends seamlessly with our original house. We are beyond happy with the results!"

"I hired Iconiq Construction to do my kitchen and I?m really happy how it came out. Sean and his guys were great, they told me what?s going on all the time so I never had to wonder. Everything went smooth, no waiting around, no extra money they ask for later. The kitchen looks so good now, better than I thought, and I?m glad I went with them."

"recently hired Northwest Builders & Renovation to build my garage, and I couldn?t be happier with the results. From start to finish, their team was professional, responsive, and detail-oriented. The communication was clear every step of the way, and they delivered exactly what they promised ? on time and within budget. The quality of the framing, concrete, and finish work exceeded my expectations. They took care of everything efficiently, handled permits smoothly, and left the site clean every day. It?s rare to find contractors this reliable and dedicated to doing the job right. I highly recommend Northwest Builders & Renovation to anyone looking for skilled, honest professionals who truly care about their work."

"Randy and Amber did a wonderful job on my project - new carpeting in the Master Bdrm., paint kitchen cabinets and add hardware, remove carpet from two rooms, add new wood, refinish existing wood to new wood and dye it all to a warm dark tone. Lots of work and they did a great job. It was really great to have ONE contractor that could do all the work that was needed. The pricing was very reasonable and they were always cheerful and open to my questions. I would highly recommend them. Nice team!"

"The eight month long addition and kitchen remodel went well due entirely to the stellar work ethic and efforts of the personnel who were onsite each and every day. We were very happy with the subs and crew that Excel General Contractor uses. The crew were professional, punctual, and took great care with the details. We had complete faith in Oscar, who primarily led our project, and his team. The final product is beautiful and we are so happy we decided to move forward with such a big project."

FAQs for addition to existing structure building service projects in Renton, WA

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.
