"John and his team do amazing work. Built a stunning custom office space with a floor to ceiling library, custom cabinets and custom French doors that blended into our existing home design. I’ve owned a number of homes over the years and I’ve never worked with a builder more dedicated to quality and with more experience than Bay."

"Joe, Abel, and Crew did an awesome job building our 28’x8’ Timbertech deck, 25’ elevated on a hillside. Joe worked closely with the Mill Valley permitting office to get the engineering plans approved, and once we got the green light the deck shot right up! We’re extremely happy we chose them to build the deck and would happily recommend for anyone looking at similar projects."

"A million thank u's to Declan, Jackie, Vince, Alex and Holden. Job well done! My bathroom and loft look wonderful. I was very nervous about this project. Had a previous issue with someone else who ghosted me and left my vanity in the dining room. Nice huh? Luckily, Jackie called me though Angi's list, booked an appointment and the rest was magic! Attention to detail, quality and accountability describes this company. Thanks again everyone! I'll be seeing you in the spring!"

"I hired them to do pest repair and paint the outside of my house as I was prepping for a sale. The quality of the work was excellent. I was informed at every step if something additional needed repair and given options. The paint job was superior. They let me know when the were coming, always showed up on time and didnâ t leave until the work was done. I highly recommend their company."

FAQs for addition to existing structure building service projects in Lagunitas-Forest Knolls, CA

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.
