A thorough roof inspection should cover shingles, flashing, valleys, chimneys, skylights, pipe boots, gutters, attic ventilation, and interior signs of moisture.
The best inspection reports include photos, plain-language findings, and a clear explanation of which items are urgent versus which can be planned as maintenance.
For Alexandria and DMV homes, flashing details and ventilation deserve special attention because many homes have additions, low-slope transitions, mature tree cover, or older roof assemblies.
