"This was my second time contracting Dorson / Jackson Construction. We had an upstairs half bath that was dark, gloomy and little more than a toilet and urinal. We wanted to transform this space, along with some additional work on our front porch, roof and living room. Dorson came through again and we could not be happier with the results."

"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 hired Western Builders Inc. for our bathroom remodel and they transformed it into a beautiful warm space filled with finish trim details and lighting, The remodel was quite heavy, needed lots of structural repairs from water leaks in the past the floor was collapsing in some areas, needed new plumbing, electrical, all the fixtures bigger window, added dividing wall with pocket door and lots more, they exceeded our expectation, We are absolutely thrilled with the result and grateful for the excellent work and commitment, Sam the owner and Bill the onsite foreman are just a pleasure to work with, and their crew were very respectful and careful of our home during remodel, They adhered to the schedule and budget everything went like clockwork. We definitely recommend them to anybody for any type of remodel, kitchen or bathroom."

"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."

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