When reading the reviews that my customers wrote about work that I have completed it will provide you with definite reassurance that no tasks can not be done.

"I can't say enough about the professionalism and exceptional quality of work from McCann Home Remodeling Services! We completely transformed our home, taking many areas down to the studs. The project included a brand-new kitchen, an updated bathroom, and the addition of a half-bath in the basement. Some standout features included a redesigned staircase with sleek glass railings, a modern deck featuring the latest wire railing technology, and upgraded plumbing and electrical work—complete with smart-connected light switches as per my request. Anthony and his team are true experts. Seeing the incredible transformation from day one to the finished product is almost unbelievable. They were reliable, hardworking, and always accommodating, even when I made last-minute changes. If you're looking for top-tier home remodeling or repairs, McCann is the team to call. You won’t be disappointed!"

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

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.
