Hello, my name is Al Birkenmeier, I am president of Birkenmeier and Sons, Inc.. So grateful for Angie's List and the Super Service Award 11 years in a row. I started my custom building and remodeling company in 1980 after 9 years in the commercial construction industry working with companies like McCarthy Bros., Hercules and Tarlton. I have pursued my love of providing the highest quality of construction while working hard at keeping my overhead down to keep it as affordable as possible. The proof is always in what my past has to offer so please don't hesitate to contact my past clients through a client reference list I would be happy to share with you as 99.9% are not Angie's List Members. Our quality of work and service is second to none so please let us offer you a no cost estimate and opinion for your next custom home or remodeling project. Thank you much, Al Birkenmeier

"I’m not sure where to start with this review. I faced several challenges with insurance and finding the right contractor to take care of spring storm damage and make repairs to work a previous contractor performed to my home. I met with Al Birkenmeier and showed him everything that needed to be repaired. The QUALITY of the materials and work done was impeccable and reminded me of how things use to be done years ago. Bobby, the carpenter, treated me respectfully and didn’t cut corners. Al only uses subcontractors he trusts to do the same quality work and ALL of those subs did exactly that! My house is fixed and is warmer due to the other work that needed to be redone just in time for winter. I can’t thank Al, Bobby, and the Subs enough and I appreciate ALL of the work done. The work wasn’t just good enough, it was above and beyond my true expectations!"

FAQs for addition to existing structure building service projects in Saint Charles, MO

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.
