Record the details you want to preserve
Photograph the roof profile, edges, visible trim, and relationship to walls and porches from safe ground-level positions. Explain whether you want the closest practical match or a new appearance. Those priorities help the contractor discuss the actual product and details, rather than assuming that a similar color alone will produce the result you want.
Check property-specific design questions early
Pasadena’s Design and Historic Preservation section provides information about design review and alterations to historic resources. If your home has a designation or known design requirements, share the relevant documents before selecting a different roof material. Ask the city and contractor which steps apply to the specific property; this page does not determine its status.
Separate visible matching from underlying repairs
If a repair is proposed, ask about replacement-piece availability and how the repaired area will look beside older material. Also ask what work is needed beneath the surface and around openings or edges. A good-looking match and a complete repair are related but separate parts of the discussion.
Avoid guessing beneath trees or deep shadows
When the aerial image obscures a roof edge, tell the roofer which area is uncertain. A porch or lower roof can disappear under a canopy or behind the main roof in a poor view. Use the planner to communicate the layout, then let the contractor verify the measurement and condition on site as needed.
Ask for alternatives that preserve your priorities
If both repair and replacement are viable, request a clear explanation of what each includes and what it leaves for later. Keep product selection, design questions, and proposed work together in your records. Your independent roofer provides the final quote, construction agreement, and roofing work; the city resources below are available for current local process questions.
