"Not only did Derrick and his crew completely redo the foundation of our house plus install flooring, but they were timely polite communicative easy to work with and did an excellent job. I can’t say enough good things about them. They took over a project in the middle of it and coordinated with us as it’s our vacation home and we don’t live in the same town. I can’t begin to tell you how much we appreciate them and will be using them in the future!!!"

"They did a fantastic job building the deck I've always wanted. I told them what I needed, and they completed the project perfectly, even in the rain! I would hire them again in a heartbeat. Very professional and personal at the same time. Woo-Hoo!!!"

"Only thing they did themselves was the patio ceiling & French drain for my project. Acted as hiring contractor for all the other work. Overall project was a success, but I didn't appreciate how the lead crewman/ owner spoke to his employee. Subcontractors that were hired were excellent."

"Jose with Bellos construction is a kind person and a man of his word. The project ended up taking a little longer then planned do to minor complications. Jose still honored his original quote. Jose is a man of integrity and he holds his crew to high standards. I will use Jose and Bellos construction again in the future."

"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."

"After getting quotes, hiring a company & later firing that company to build us a deck under our deck, we were really defeated thinking our very sloped useless backyard would really ever have usable space. I found a recommendation for Mike at MG Exteriors on Happy Valley Chit Chat and gave them a call. He came out quickly for my quote (not a salesperson but the owner) and quoted us on the spot. He also looked at my existing deck & recommended we protect that one pre-construction of the new one (it was only 2 yrs old but already looked sad. We received a fair quote (less than the 'fired' company) and they were able to start us quicker due to a cancellation. Construction was in time, they were punctual, clean and ALWAYS available for questions. Highly recommend!!"

"Pacific Floors guys installed our new hardwood floor and kitchen tile. The work performed by Pacific Floors was top notch and I would highly recommend them to anyone looking at installing new floors or tile. Our Portland house looks great and it is all due to their craftsmanship, attention to detail and quality control. We could not be happier!"

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