Original decking on older Diamond Bar homes is more often than not skip sheathing, which changes what can be laid over it.

On most jobs, we do not advise filing a Diamond Bar claim where the harm is clearly age, because a declined claim stays on the record. Worth knowing before you sign anything. In practice, policies covering Diamond Bar properties generally pay for sudden damage and not for age, so the report has to separate the two clearly. On most jobs, emergency tarping on a Diamond Bar roof is normally covered, and receipts should be kept for it.
