One look at a Johnson Custom build and you'll immediately understand why so many discriminating customers recommend us to their friends looking for a higher level of customized home building. It's not just about the attention to detail or use of the highest-quality materials or even the custom-crafted details. It's about the personalization. Personalization that comes from a builder that not only knows how to listen but also how to anticipate, communicate and most of all deliver on a promise. A native of Kirkland, Washington, founder Ryan Johnson shares the same core values as the community he has always called home: Integrity, Honesty and Originality. He's been actively designing, building and remodeling homes in the area for over 25 years. And in that time, he has earned a stellar reputation for providing outstanding results crafted with uncompromising integrity and quality. Hes also earned a reputation for delivering on his promises. A+ rating on the Better Business Bureau (BBB) !

"Ryan and his crew did a great job building out Car Port. From the first time we talked to a completed project was about 6 or 7 weeks. He and his crew were very professional and, came on time, and exceeded my expectations with respect to the quality, time to finish, etc. Ryan also collaborated with another team of professionals that were contracted to place Solar Pannels onto the Car Port that was just completed. He made sure that all of their requirements and spec were addressed while building the Car Port. THANK YOU Ryan and Co!"

"I can highly recommend Val to handle any remodeling job you have. Mine started as a kitchen, bathroom, staircase remodel but grew to an almost complete home remodel. Foundation issues were discovered in my 1949 built home that required the management of multiple subcontractors, architectural services, permit processes. Val and his team were able to manage everything that came up. The process took twice as long as originally planned because of the foundation issues, but Val handled all issues that came up. He kept me informed of timelines, vendor issues and remained wonderfully helpful throughout it all. My daughter and her husband signed Val up for their remodel as a result of the help and expertise he provided with my remodel. "

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