2Finding the Problem on a Diamond Bar Roof

We photograph every elevation on a Diamond Bar job so the written estimate can be read against what is actually up there. Put simply, photographs with dates are part of every Diamond Bar inspection, because an undocumented claim gets read as wear and tear by any adjuster. Realistically, a Diamond Bar roof covering is inspected from the attic as well as the roof covering surface; half the evidence is underneath. A Diamond Bar inspection should end with a written report and photographs, not a verbal summary and a price. We inspect the deck from inside the attic on every Diamond Bar job. Daylight through the sheathing tells you more than anything visible from the driveway.

Mixing materials across a Diamond Bar roof covering is fine provided each section gets the system it calls for and the transitions are flashed properly. As a rule, standing seam on a Diamond Bar property hides its fixings, which removes the most common leak path on exposed metal.

On most jobs, most Diamond Bar claims that fail do so given that the deterioration was cleaned up or patched before anyone photographed it.
