Customers say: Quick response

"Updating our home was a dream we have had for years. But finding a good contractor in Bay Area was so difficult, that we almost gave up. We were introduced to United C Construction by our architect(who we also love!) It was exhausting trying to find someone trustworthy and not overpriced. We had luck of working with Osmar which during the project we had clear communication, expectation of setting, professionalism and superior craftsmanship. He walked us through every step of the way, and helped problem solve tough permitting and structural issues in Berkeley!"

"We want to add to our earlier review. Carnhill Construction has been our go to for the past 6 years. They have dealt with a stone deck that kept leaking refuse down the facade, painted our entire house inside and out more than once, had our wood floors sanded and refinished, repaired cracks and leaks in the siding of the house, repaired a balcony. They have been very creative and innovative in coming up with fixes. As we stated earlier they are professional, reliable, consistent and their communication is immediate. We rely on them to deal with any house repair we need. They are a pleasure to work with. We would recommend them highly to anyone needing any house repairs whether a small or extensive project. "

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