"Just had our kitchen remodel completed by them and couldn’t be happier! Job was done in the estimated timeframe and on budget. Stan was great to work with. He made great recommendations when we were unsure or stuck on something, and kept us well informed on timing and any issues that came up every step of the way. He and everyone he brought in were very professional and worked hard to get the job done. We are already planning to have more work done by them in the near future. Highly recommend."

"Only thing they did themselves was the patio ceiling & French drain for my project. Acted as hiring contractor for all the other work. Overall project was a success, but I didn't appreciate how the lead crewman/ owner spoke to his employee. Subcontractors that were hired were excellent."

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