Wind and storm damage on a Diamond Bar roof is covered where it is documented; wear is not covered anywhere. Supplements are normal on Diamond Bar claims once the covering is off and the deck is visible, and they should be raised with evidence rather than argued later.
Phasing a large Diamond Bar building across two seasons is commonly cheaper than financing the whole job at once. As a rule, deck replacement on a Diamond Bar job is unknown until the tear-off, which is why it belongs in the contract as a per-sheet rate. Cheap Diamond Bar quotes usually skip the flashing. That is where the money is saved and where the next leak arrives.
