The the San Fernando Valley Annual Roof Inspection Checklist — Contractor Perspective
What a real inspection covers on roof maintenance in the Valley, and what a written report should contain.
A roof inspection is only as good as what gets looked at, and a lot of what gets called an inspection is a walk round the garden with a phone camera. This is what a real one covers on roof maintenance in the San Fernando Valley.
What actually matters
Maintenance is not repair. It is the set of small checks that stop a fifty-dollar problem becoming a fifteen-thousand-dollar one, and its value is measured in the calls that never get made. An inspection that does not account for that is looking at the wrong layer.
The detail that is usually left out
An inspection is only as good as what gets looked at, and photographs of specific defects are what let you get a second opinion without a second visit. Timing matters more than frequency. One visit in late autumn, before the rains arrive, is worth more than three spread randomly across the year. Anything under half an hour on an average house has skipped something.
What is specific to the San Fernando Valley
Summer is the problem here. The Valley runs ten to fifteen degrees hotter than the coast and holds it for weeks, so a roof surface that reads 90 degrees in Santa Monica is well past 160 in Van Nuys by mid-afternoon. Everything on the roof expands into that heat and contracts again overnight, and it is that daily movement, not the peak temperature, that opens laps and backs fasteners out. Most of the housing went up between 1950 and 1975, which means original decking, undersized ventilation and at least one previous layer that somebody roofed straight over rather than tearing off.
The full inspection list
- 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
Is a free inspection worth having?
It is, provided the report is written and itemised. What you are watching for is an inspection that finds only work the inspector happens to sell.
How long should an inspection take?
Long enough to get on the roof and into the attic. Anything under half an hour on an average house has skipped something.
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 Fernando Valley the thing to watch is attic temperature and intake ventilation, because a Valley attic that cannot breathe cooks the underside of the roof as hard as the sun cooks the top.
