Use the property’s location, not a broad region label
Include the full address and identify the building or unit. A Los Angeles-area mailing address is not a substitute for confirming the authority responsible for a particular project. Ask the contractor which local process applies. The Los Angeles Building and Safety resource below is a starting point for properties within its jurisdiction.
Begin with the question you need answered
An active leak calls for an assessment of its cause. A planned replacement calls for a complete work specification. A material comparison starts with product suitability and appearance. Say which of these best describes your project, and add the timing, repair history, and any special access arrangements you already know.
Separate the buildings and roof systems
Identify a main house, detached garage, rear unit, or commercial area separately if more than one is included. Note changes between pitched and low-slope roofs. If ownership or responsibility is shared, explain who can provide access and approve work so the contractor can assess the intended areas with the right people involved.
Treat online planning as a conversation starter
Trace only the roof areas you want to discuss, select the pitch assumptions you know, and flag any unclear imagery. The outline does not inspect the roof or reveal concealed damage. A contractor verifies quantities and work conditions before providing a final price; a planning result is not a material order or construction contract.
Know who takes the project forward
Your Roof LA is the planning and referral service. The independent roofing contractor reviews availability, assesses the property, provides the written quote, contracts directly with you, and performs the work. Confirm that contractor’s identity, license status, scope, and terms before hiring. You can use the CSLB resource below to check the license information you are given.
