"Emrah was amazing to work with from start to finish. His price, including labor, was a lot less than two other estimates I got. I would highly recommend B & E Construction to anyone wanting to paint the exterior of their house."

"From the first encounterit was apparent that Javier was an accomplished contractor. He posed questions and offered counsel on what could make working with him highly successful. Posing questions, offering his advice, and calling out oversights from the original construction in the 70s. While he and his subs were working it became clear he was going to work with us as we modified the original scope of the work. We’re looking forward to the next to-do on our list."

"They gentleman are outstanding! They help my mom out after a disaster with Great Floors on a complete home remodel. Took things over and made lots of adjustments they didn't have to do. Truly can be trusted with your work and do most of the work theirselves with little sub contracting. Also did a complete fix on a room at my house that flooded. Again I can't say enough!"

FAQs for addition to existing structure building service projects in Prosser, WA

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.
