"When we first decided to have a large deck built we went with Mr. Huff due to recommendations of other people . We were given a contract with cost and start date and finish date. Everything done as agreed and cleanup was great. We had not discussed cleanup but it was done with both decks. Price of projects very reasonable. Highly recommend this company."

We were doing a living room and front deck expansion project and Paul and his team delivered a beautiful completed project and on budget. I have already recommended Triple D to two other friends for assisting them with their current projects."

I recently left the union as a journeyman carpenter and superintendent. I built custom homes in my 20’s after graduating from college with a bachelor’s degree in business administration. Before college I worked in all phases of construction from concrete and framing to finish work. I have a well rounded understanding of building and am passionate about what I do and the quality of work I provide. In my personal life I am led by Jesus. I enjoy running several times a week and working out in my home gym. My goals are to provide value to my clients and give back to my community.

".We were very happy with Happy Const.  Bradley responded to my phone call promptly, provided a bid when he said he would, and started worked promptly.  The job took about 2 days and Bradley cleaned up after each day.  Since the work was being done in our bedroom we appreciated this.  Bradley had a couple of suggestions that really improved the project with only minimal additional expense.  We will definitely call Bradley again.

FAQs for addition to existing structure building service projects in Sweet Home, OR

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.
