Post-Storm Roof Walk: What to Look For — Myths and Facts
What to do about roof maintenance in the San Gabriel Valley in the first forty-eight hours, and what to leave until Monday.
After a storm the useful work happens in the first two days, and most of it is documentation rather than repair. This is what to do about roof maintenance in the San Gabriel Valley once the wind drops.
What actually matters
Roofs in this climate do not usually fail from one dramatic event. They fail from debris nobody cleared, a sealant nobody renewed and a slipped tile nobody replaced, compounding quietly across several dry years until the first real storm finds all three at once.
What to do in the first forty-eight hours
Document before you touch anything: wide photographs to establish the property, then close photographs of each item of damage, all dated. Timing matters more than frequency. One visit in late autumn, before the rains arrive, is worth more than three spread randomly across the year. A tarp fixed through sound covering creates damage that was not there before.
How the San Gabriel Valley changes the answer
Heat and airborne grit arrive together. The Valley traps particulate against the hills, and that grit settles into every horizontal surface on the roof, then washes into the drainage in the first storm. Combine that with sustained summer heat and you get roofs that age from accumulated debris as much as from weather. Tile is everywhere, much of it laid in the 1960s and 1970s over a felt underlayment that has long outlived its design life while the tile above it looks perfect.
What we look at on an inspection
- Gutters, valleys and drainage cleared and flowing
- Sealant condition at every penetration and transition
- Slipped, broken or missing units across the field
- Flashing and counterflashing at walls and chimneys
- Tree overhang and any branch making contact with the surface
- Ventilation openings clear and unobstructed
- Interior ceiling and attic check for early staining
Common questions
Should I get a tarp on it straight away?
Only once it is photographed, and only if it can be fixed without putting new holes through sound covering. A badly fixed tarp creates damage that was not there before.
How soon do I need to report it?
Check your policy, because most impose a reporting window. Reporting early costs nothing and protects the claim.
The honest summary
Nothing on a roof stays fixed by itself. An hour of attention before the rains prevents most of what would otherwise become an emergency in December. In the San Gabriel Valley the thing to watch is underlayment condition beneath sound-looking tile, and debris load in valleys and gutters.
