"Jared and his team did an amazing job. From start to finish, it was clear they wanted to make sure we got what we wanted. Jared worked with us to come up with the design, and the team were all great to work with. They continuously kept us informed of what they were doing, and if something needed adjusting after it was done, they were very quick to make any requested changes. The job included removing a window, and re-sizing two others; replacing siding on the exterior and matching our existing paint; re-sizing the living room archway; replacing kitchen and bath flooring with tile; removing a bathtub, re-arranging the bathroom and adding a large shower; moving a tankless water heater from outside to inside; re-routing gas and water for the washer and dryer; installing new appliances; installing cabinets and quartz countertops. I highly recommend this company and will be hiring them again for future projects."

FAQs for addition to existing structure building service projects in Vashon, WA

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.
