A brand new roof, on a new build, an addition, an ADU, or a garage conversion, is a chance to get everything right the first time. There is no old material to work around and no shortcuts hiding underneath. Orian Construction & Roofing installs new tile, shingle, metal, and flat roofs across Los Angeles County, built to code and to last.
A replacement goes onto an existing house, over an existing structure. A new installation goes onto something that never had a finished roof: a ground-up build, a room addition, a detached ADU, or a garage being converted into living space. The work is different because we are starting with bare framing or new decking, which means the roof can be planned and built as one clean system instead of adapted to what came before.
That clean start is an advantage worth using. On a new roof we set the ventilation, the underlayment, the flashing, and the covering to work together from day one, without the compromises that come from matching an older roof. Whether it is an addition tying into your current roofline or a standalone ADU, the details at the transitions are where a new roof succeeds or leaks, so those are where we spend the care. For a full home reroof rather than a new structure, see our roof replacement and reroofing pages.
We also work alongside general contractors and homeowners acting as their own builder. If you are running a project and need the roofing handled by a licensed crew, we fit into the schedule and coordinate with the trades around us. Reach us through our contact page to talk through the build.
A new room or second story needs a roof that ties cleanly into the existing one. The valley and wall transitions are the make-or-break details, and we build them to shed water.
Accessory dwelling units are common across LA now. We roof them as complete little buildings, matched to the main house or built to their own style.
Turning a garage into living space usually means upgrading the roof to a habitable-space standard, with proper underlayment, ventilation, and often better material.
Ground-up homes and structures get a full roofing system installed to current code, from the underlayment through the flashing and covering.
Suits Spanish and Mediterranean designs, lasts for decades, and handles sun well. A strong choice when the look fits the home. See tile roofing.
Tile →The practical, cost-effective choice for most homes and additions, with a clean look and a solid life in our climate. See shingle roofing.
Shingle →Metal for longevity and fire resistance, flat systems for ADUs and modern additions. See metal and flat roofing.
Metal & flat →Family owned and based on Ventura Blvd in Sherman Oaks. On a new roof there is nothing to hide behind, so every layer is done the way it should be.
We review the plans or the structure, help you choose the material, and give you a written estimate.
We confirm the decking is sound and lay the underlayment that forms the roof's water barrier.
We build the flashing at every transition and install the tile, shingle, metal, or membrane to spec.
We confirm the roof passes inspection, drains correctly, and leave the site clean.
We install new roofs on builds, additions, and ADUs across the county from our shop on Ventura Blvd in Sherman Oaks. A few of the areas we serve:
