Granules and gutters
Heavy granule loss shows up in downspout exits and splash blocks. Some shedding is normal on newer shingles; sudden increases after hail or wind merit follow-up.
Missing or lifted tabs
From across the street you may see uneven color bands or lifted corners along prevailing wind directions. Close-ups help when lighting is consistent.
Flashing and penetrations
Look at chimney sides, vent stacks, and wall intersections for bent metal, gaps, or caulking that has cracked away. Those junctions drive many slow leaks.
Ridge line and slopes
A visibly wavy ridge or sagging plane can indicate structural or decking issues. Compare your roofline with neighbors at similar ages when possible.
From the attic
With lights off, scan for daylight through the deck and for stains that follow rafter paths. Musty insulation after rain suggests water paths even when shingles look acceptable.
Next steps
Use our storm checklist after severe weather. When signs pile up, book a professional inspection rather than guessing from the yard alone.
