"Several years ago they remodeled an older home I own. Because they are so good, we used them to build a new home on 10 acres. They are very adaptive to our changing ideas. We worked with them in making changes as the work progressed. This has been either because we see a need for a different design or in response to their suggestions for how to make things nicer. There input was extremely important in adapting our new home to a steep hillside. There work is of the highest quality and they work with us in deciding on subcontractors. The support does not end with the end of the project. The have dealt with the subcontractors each time an issue has arisen in the months following completion."

"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."

"I had a 15 foot section of sidewalk the city mandated required replacement. Toro DEMOd and replaced the sidewalk in one day. The work was clean and defect free. Further complicating it was the sidewalk had a 4 foot wide section to a 5 foot wide section. They measured and lined out the frames to cleanly taper it in to the point where it is not noticed at all. Will definitely call them again for future projects. Will definitely call them again for more projects."

"I contact Jeff on a Sunday and was in desperate need for a sliding shower door installed ASAP. Jeff was able to come out that day installed the door. He did great work at a fair price and even made time to check in later to make sure the door works properly. The next job i have around the house I'll be calling Jeff."

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