Specify the metal roofing system
Ask for the panel profile, metal specification, finish, fastening system, underlayment, and flashing details in writing. Compare bids for the same assembly. Discuss penetrations, transitions, and how the crew will address expansion and contraction.
Plan installation access
Long panels and roof access can affect installation logistics. For a West Hills property with a steep approach or limited staging, ask the installer to walk through delivery and lifting arrangements. Confirm who is responsible for protecting landscaping and adjacent surfaces.
Compare ownership costs using your own assumptions
Use the lifecycle worksheet to compare installation and maintenance assumptions, then replace them with actual bids and product guidance. Do not treat a modeled lifespan or resale value as a guaranteed return. Ask the installer to explain maintenance and warranty exclusions.
Check approvals before ordering
For a material change, check the property and scope through the permit planning guide. If solar is part of the project, coordinate roofing and solar installation with both contractors. Ask which manufacturer approves the proposed system.
Choose a contractor for the scope
Before signing, check the Oregon CCB license and compare the written scope, payment schedule, and warranty. You can request a roofing referral through this site; confirm the contractor’s credentials and availability before hiring.
