"Grant and Bailey were AMAZING. Not only were they able to help me out immediately they did everything so quickly! Absolutely would recommend them. Good people with kind hearts are hard to find. You would be remiss to not use them for any of your needs."

"Communication is important when two families own a house together, and Rory managed to pull this off both BEFORE and DURING the construction process. He was very clear in telling and showing us what we could expect, and on a daily basis answered our questions and concerns. The project turned out great and we will definitely use him again!! I also need to say we enjoyed working with his entire crew."

"Considering we started a new build in the Covid era, Mark knew when and where to order materials so that they arrived on time and at a reasonable price. He scheduled sub-contractors in a timely fashion and finished our project within a year. Marks primary crew Miguel and Trace did an outstanding job from foundation to finish and were a pleasure to work with. Mark has been in this business for many years, he is patient and has a sense of humor to get you through the difficult times. We would recommend Mark Petrie for any Custom Home you may be considering."

"Central Oregon Excavation were wonderful to work with. We had a difficult yard area to navigate around that later required a 70 lb crane to get the equipment to the intended area. The owner, Bill, was super up-front and honest about the quote and what it would take to complete the job. These guys were problem solvers, professional and were on time everyday. They completely did a great job. I highly recommend Central Oregon Excavation+"

"Brice and Andrew were awesome to work with. We had our backyard completely redone with new patio, gas fire pit and all new xeroscaping put in. Andrew kept us informed every step of the way. The yard looks amazing and they stand by their work, even coming back to check on a few items after the project was complete. I don't want to give them a good review because we don't want them to be too busy for future projects. We'd totally hire them again."

"We couldn't be happier with the quality of the work Matt Burkhardt completed on our very large kitchen addition and home remodel project. Choosing to work with Matt for our home and kitchen remodel project was the best decision we made. Matt is the kind of experienced, detail-oriented "perfectionist" that we trusted completely to bring our remodel dreams to fruition. We are so pleased with the quality of his work, his craftsmanship and his attention to detail and "getting everything right". He was always professional, honest, fair, experienced, super easy to work with and a great communicator. Matt responded quickly and effectively to all of our many emails and questions throughout the process. We would unhesitatingly recommend Matt and Burkhardt Construction for any small or large home addition or renovation project."

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