"We have a long standing relationship with Fredrick James Construction. We have worked with this company for over 10 years. They have replaced flooring for us and have done numerous home improvement projects. Our most recent project was the re-siding of our home. We had Fredrick James Construction remove our old vinyl siding, and re-side our home with Hardy Plank. We also had them replace 10 dated vinyl windows and replace them with 10 new, vinyl windows. The house looks amazing. Everyone on the crew is polite and very skilled. As with all remodel projects, some unexpected 'surprises' arose, but as usual, Fred and his crew knew exactly how to address the problem and everything turned out wonderfully. What I appreciate about Fredrick James Construction is that each of the workers are respectful, skilled and work hard to finish the project in a timely manner. We recommend Fredrick James Construction highly for any of your remodel or repair needs."

"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"

Their work was thorough and the fence looks great. Their team was respectful and kind when doing their work. Overall had a great experience and would work with them again."

"I couldn't Recommend Steve Orme enough! He has constructed large shops, outbuildings, in addition to a lot of work on our houses, on the McKenzie river. Steve and his crew are punctual, possess excellent communication skills, are creative, and flexible as well. We have been 100% satisfied with all the projects we have had him complete, and will definitely use his services again in the future. Steve's reputation for excellent work is well known throughout my community, and he has built a reputation for fair priced, quality results. He's always in demand."

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