"We hired Topline Builders and Renovations for a full home addition, adding nearly 600 square feet to our main floor. From the very first consultation, Ben walked us through the architectural plans, structural requirements, and permitting process with the city. We were nervous about taking on such a large construction project, but they made it feel organized and manageable. The framing crew worked efficiently, inspections passed without delays, and the final finishes blended seamlessly with the existing structure. You honestly can?t tell where the old house ends and the addition begins. Communication was consistent throughout the entire process. This wasn?t just a contractor showing up ? this felt like a professional construction team managing every detail properly."

"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!"

"Highly recommend Lopez Bros Construction for any remodeling and major home repairs. We completed major home repair and remodeling, including bathroom shower repair and remodeling, Kitchen and Living Room ceiling/internal skylight enhancements, Interior and Deck Painting, and Basement Remodeling. Ray has been always going above and beyond in delivering the results. He will make sure the details and end results are perfect. His team's integrity is unquestionable, responsiveness and quality are top notch. Given the multiple projects he's dealing with, his crew still manage to get the repairs and remodeling done on time, as promised. I would hire Lopez Bros Construction again for my next project."

"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."

"Dave Thacker is old school. He gives you a quote for your project and sticks to it. If he finds something he missed, he doesn't charge extra and fixes it. He gives fair quotes, works fast, and is really a pleasure to work with. While he was at my home my old fence blew down. I had him fix that too. Both the deck and the fence look professionally made, like the professionals that built them! I would definitely refer a friend or relative to PlanTrak!"

"It went amazing! NWPM do awesome, high quality work. They pay attention to every detail and are very neat and tidy. Everything is done with expert craftsmanship and very straight, clean lines. I can not do what they are able to do for me; their work in just a few days replaces all the work that would have taken me weeks or months to do myself and I would not have the same clean finish. I enjoy my almost 20 year old home so much more after all the work they have done to update it!"

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