"I just warn other people about their scam like business tactic. They added up overhead charge (8% of labor cost) and whatever material they used to finish the job. So an upfront estimate they give you is only labor cost. Be careful before you hire."

"I wish I could give Maarten and his team of contractors 10 stars. He far exceeded our expectations. His contractors/workers were always working, doing things that went beyond the scope of the project. Our house/yard was in better shape than when it started. He is one of the only, if not only, contractor I would have do worker prior to getting an estimate. While he was installing the new roof (with an estimate) we had his team working on eight other projects with just a verbal ballpark estimate and he came in below what was expected. Maarten is extremely knowledgeable and was able to resolve issues we have had that other contractors were unable to fix. I would recommend Reston Restoration for any project in the home. Thank you to the Reston Restoration's team"

FAQs for addition to existing structure building service projects in Washington DC, DC

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.
