"Paul Derosia of Triple D is a high integrity individual. He is polite, soft spoken, and knowledgeable. He showed up on time, every day, and took painstaking care to do the siding and painting job as if it was his own home. The siding installation, the window trim, the caulking, and the painting were all done professionally. Paul doesn't just bid a job, and then hand off the work. On any given day, Paul could be seen on a ladder or the scaffolding, and even with a paint brush in hand. I don't typically provide public reviews of contractors, but, I was impressed with Paul, his skills, integrity, and work ethic. I am extremely pleased with how our home looks, and I have the confidence that I won't have to deal with the exterior of our home for a long time to come! Gary Mallory Gresham, Oregon"

"We had a 200sq ft shed built by another company and had Steve Anderson Construction come in after to build out the interior. Everything other than the actual structure was done by Steve and his team. (Electrical, plumbing, framing, drywall, hardwood floors, staining, LVP Floor, cabinets, tile,etc) Steve's team was great to work with, and everything came out better than I could have expected or asked for. Don't mind the mess in the photos. Just wanted to show their work."

I recently left the union as a journeyman carpenter and superintendent. I built custom homes in my 20’s after graduating from college with a bachelor’s degree in business administration. Before college I worked in all phases of construction from concrete and framing to finish work. I have a well rounded understanding of building and am passionate about what I do and the quality of work I provide. In my personal life I am led by Jesus. I enjoy running several times a week and working out in my home gym. My goals are to provide value to my clients and give back to my community.

"NW Builders & Renovation is the best that Portland has to offer. Tops in professionalism is Max, who was our point man for the roof project. He uses only the best materials, top of the line building and roofing materials make our job one that will last for a lifetime. I have confidence in Max, he was always there for any questions I had and when I had an unexpected disaster - a ceiling fell on me, he was right there, offering to come to my house and help me, in my hour of need, he was there. He finished the job with time to spare, and they did a thorough, excellent job. Now I have no fear of rainstorms making my roof leak, I can confidently decorate my home and know that the roof won't leak or fall in. Not only did they do a thorough and excellent job, they cleaned up all the mess that was left over after finishing. If I had to do it all over again, I would definitely choose NW Buildlers & Renovation and Max. my favorite go to roofing guy."

"The company was very professional in contacting us and following through on the work. The work done was done very quickly and met the request made. Work was done well and very efficiently. Quality paint used that provided additional warranty security. Communication was good throughout the project and follow-up to questions was provided when requested."

FAQs for addition to existing structure building service projects in Cascadia, OR

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.
