"Stag Construction was hired to replace poorly installed Hardi Board siding and replace patio doors and window. Pictures show after corrections of miscut siding, siding pattern not running in same direction, siding not even from panel to panel, wavy uneven fascia, 2"gaps between soffits and siding, roof edges straightened and more. Fascia is now straight and runs parallel to top of windows and no holes/gaps for rodents to enter. Amazing! Due to the unknown extent of the work, contract was" by the hour, not a bid. What a pleasant surprise to deal with a company that knows how to install so as not to void a warranty. Austin and his brothers were professional, knowledgeable about the product, courteous, and efficient. Work hours calculated accurately and materials receipts were detailed. I appreciated their willingness to discuss options and express opinions when asked. Stag Construction will be doing more work for me next spring. Looking forward to it!"

"Efren and his crew at ED Enterprises did an incredible job on our bathroom remodel. They were easy to work with, thorough, timely, and had great communication throughout the process. They kept us in the loop as things progressed, always showed up when they said they would, did great quality work, and left things clean and tidy - not only when they finished but as they worked on the project. We are thrilled with the work they did for us and will absolutely reach out to them for our next project!"

"Tylor & Jake were professional and courteous. They showed technical competency and finished the job as promised. They could have done a little better job in keeping me informed about scheduling, but this does not take away from my rating at all. Great job!"

"Gabe was very professional, his crew was very clean and tidy. They worked their tails off no matter the weather. I was impressed with how efficiently they were able to get things done. It was a great process from start to finish and I couldn?t be more happy. I will be using this company in the future and recommend them to anyone needing anything built."

FAQs for addition to existing structure building service projects in Lolo, MT

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.
