"Tony did a fantastic job! He was very helpful with suggestions in the design of our deck. After the old deck was removed he found some structural issues. He did a great job of making our deck structurally sound. Our deck was completed in a timely fashion as promised. His workmanship and attention to detail can be seen in our finished product.Tony was extremely easy to work with and would highly recommend him for any project"

"H & Y Contracting LLC took our basement from concrete, duct work and exposed pipes to a modern living space that we will enjoy for years to come! Everyone involved in our transformation (framers, drywall installers/finishers, electricians and painters) were professional and focused on completing to task at hand. Especially Paco...the builder's right hand man....who seemed to be here every day."

"We just got our basement remodeled by Blue Ridge Builders and we are extremely satisfied with their performance. The basement looks outstanding and the finish mirrors that of our main floor upstairs. We could not have hired a better builder. Wayne and his crew demonstrated to us that they are real professionals. The structure and finish is solid. My wife and I were looking for honesty, dependability and professionalism; Blue Ridge Builders demonstrated all of the above and more. Thank you so much Wayne. We would definitely recommend Blue Ridge Builders."

"I have used Danny at least 10 times. He remodeled an investment property I purchased and did carpentry, flooring , some electrical and plumbing. His work is EXCEPTIONAL and he has the strongest attention to details. His carpentry skills are next level, he rebuilt a stairwell and raised a roof as well. Very trustworthy guy, and did a lot of the work for me with no supervision as the property was in another state. Never had any issues and he sent pictures of the work daily. Additionally after the work was completed I started using him in my personal home in pa and he did flooring/ tile and built shelving, installed toilets and sinks and built a bar in my basement. All the work was great! Prices are very fair !!"

FAQs for addition to existing structure building service projects in Clayton, DE

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.
