"We just had our roof replaced by Cody and his team. Everything from start to finish was done professionally and skillfully. The roof looks great.

Here at Best Co. Exteriors, we believe in quality work. We pride ourselves in our ability to provide the exact exterior service you need to make your property shine. Every project is handled with top efficiency. Call today for an estimate. We look forward to earning your business. We have been providing quality bobcat and excavation services for 25 yrs.

"Do the Right Thing? Warren didn?t handle this properly, but I?ll let you judge. I hired him for a fixed-price bathroom remodel. Afterward, the pipes in the wall froze. I agreed to place the pipes in the outside wall with heavy insulation instead of along the baseboard, but I?m not a professional contractor. Also, the implementation was flawed: the vapor barrier was on the outside wall, trapping moisture, and the higher-grade insulation (R22) was between the pipes and the inside wall, insulating the pipes from house heat. Contractors I consulted felt this should?ve been fixed free since it was done wrong. I offered to pay for the plumbing but not the wall redo. Warren billed me $2,500 for time and materials, charging $55/hour for his worker and apprentice (110/hr). To be fair, the work looks great, and he addressed the issue quickly. Still, I don?t think I should pay twice for work done incorrectly. I hope this review seems reasonable."

"Aubrey and Son came out to do multiple jobs to my home starting with new flooring in two bedrooms. I needed a whole new bedroom built in my garage for my mom and he completed that job quickly and thoroughly. She stays warm in the winter and cool in the summers and is very comfortable and happy with her room, it came out lovely. Beau also built a custom shed and picnic table which also he did in a needed time frame and they both came out beautiful. Easy communication and solid work. I would definitely recommend this company to family and friends and strangers alike. "

"Jim and crew are reliable and knowledgeable. I agree with all that Dana C in Kensington shared. We hired Jim to close in a carport for an addition by seeing the work he was completing for Dana. I then had him remodel an old garage that needed a face lift. We now have Jim building a ranch home for us from the ground up. It is going just as well. If only the prices due to the economy were not so disappointing. Materials are through the roof as a result. Here hoping for some REAL change in 2025 !!!!"

Addition to existing structure building services FAQs

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.
