"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."

"Home projects, no matter the type, will have hiccups. What makes a company special is how they handle those hiccups. John and Matthew handle every issue with integrity and sincerity and willingly coached me through the questions I had throughout my projects, even providing welcomed design ideas. Once the project was complete I brought them back to do a few more things and they made the time for me. I can easily recommend these fine gentleman."

"Excellent experience. We had a need for more covered storage space to help free up some space under our covered porch by having a great spot to store children's toys and ride on cars out of the elements. We explained what we needed and showed the space and quickly Adams mind began working and offering solutions. We are very happy with the outcome and will be working with them again for other projects!"

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.
