"We have hired Paul and his team for several projects in the past several years, most recently for a kitchen remodel. He is professional, honest, the work is done to a high standard and we trust his judgment. He has replaced our windows, remodeled our kitchen and bathrooms, remodeled our bedroom , built a new deck and made cedar siding to match existing cedar siding on our home perfectly. We highly recommend him."

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 highly recommend Berper Construction LLC. We listed our project on Angi and literally 5 minutes later we received a call from Gerardo to set up an appointment to look at and give us an estimate. He came over that same day and sent us a bid the very next day. We accepted him and his team to do the work and just over a week later once we got our funds together, they began working on our project and were finished in 2 days! He was very thorough explaining what needed to be done and sent us pictures from Home Depot of different items we needed for the job and let us pick out exactly what we wanted. Always on time, very kind, and honest which is much appreciated. Gerardo made sure that he did the job exactly how we wanted and never did anything without getting our approval first. We love our 9x9 pergola over our hot tub, thank you Gerardo, Edwin, and the rest of your team! We will definitely call again for other projects in the future! :)"

"The company was very professional in contacting us and following through on the work. The work done was done very quickly and met the request made. Work was done well and very efficiently. Quality paint used that provided additional warranty security. Communication was good throughout the project and follow-up to questions was provided when requested."

FAQs for addition to existing structure building service projects in Cascadia, 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.
