Payment schedules on Diamond Bar work should track progress, never run ahead of it.
Photographs taken in advance of any tarping on a Diamond Bar property are the most valuable evidence in the whole claim. This holds across Los Angeles County. In practice, a Diamond Bar adjuster works from the scope in front of them, which is why the contractor's report has to be thorough. Worth knowing before you sign anything. Emergency tarping on a Diamond Bar roof is normally covered, and receipts should be kept for it.
