I have more than 35 years' of residential, commercial and industrial experience and I pride my company on reliability, great communication, integrity, and quality work. I will do my best to keep you as educated as we can on your particular project. I look forward to earning your business!

"We recently had our bathroom remodeled by Tanoak Construction and we are extremely satisfied with the quality of workmanship. Gant Bowman and Dave Bowman were always available to answer any questions we had and were very transparent throughout the entire process. Finding a local contractor was difficult, but Tanoak Construction made the process easy and stress-free. They were clean, very respectful while in our home, and gave great advice. Every subcontractor they brought in was also great to work with. We highly recommend them to anyone in the Sonoma County area who needs remodeling work done."

"The employees were great. A couple of days there was only 1 man on the job due to illness. The company did not replace him, so the 1 man had to work alone, slowing down the completion of the project. Art and Johnny were great to work with. Communication with the office was a little lacking, but overall we are happy with the work."

We have been in the construction industry for over 10 years. From building ADUs, high-end kitchen remodels, bathroom remodels and home extensions, we have done just about everything under general construction. Our company prioritizes safety, quality and transparency.

"Me and my wife decided recently to get our kitchen remolded. After some time searching for the right guys to do the job we settled on RG Construction. Richard, who is the owner, is a great guy and super informative. He never left any question unanswered or left us uncertain about anything. His crew works quick, and they pay attention to the tiniest detail. They absolutely are worth every dollar and I would recommend RG Construction to any homeowner, and I for sure will be giving them a call back for any work I need done in the future. Me and my wife are absolutely in love with our remodel."

"We could not be happier with the remodel of our dated, dysfunctional, tiny kitchen. Ruben was very professional, friendly and a real problem solver. He continually went above and beyond and we simply cannot say enough about what a great contractor he is. We had an unforeseen deadline and he and his staff worked very hard to make sure the job was finished. Their work was meticulous and the final result outstanding. Thank you Ruben and staff!"

FAQs for addition to existing structure building service projects in Healdsburg, CA

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.
