"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!"

"We hired Vic and his team to replace a gas range with electric. This task was complicated by the need to upgrade our electrical panel and run new cables to support the new range. We also needed to cap off the old gas line and repair and paint drywall. They made sure that everything was up to code (including correcting an existing problem they found with grounding) pulled the required permit and arranged for inspection of the completed work. We were impressed by their professionalism throughout. As well as doing quality work they also were very careful to protect our home and clean up once complete. We were very pleased with the finished job and would definitely hire them again."

"JJ construction was my #1 choice for remodeling. I made my appointment with JJ construction. The person showed up on time and very thorough. We were very pleased by their expertise and their advice. However, I decided to sell the house as is. No work was done on my house. But I do recommend this company for future projects."

"My project involved cutting into my basement floor to repair and pour 2 new concrete footings. They answered the phone on the first call and were very polite and professional. I would consider using them if I had a larger project. <br />"

"The group performed a good job updating our old bathroom. They gave sensible design advice and took care to avoid plumbing issues. Coordination should be improved and there were a couple material delays. Overall, the makeover was respectable but the communication was mediocre."

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