Attic Ventilation: Intake and Exhaust Balance — Inspection Notes
What a real inspection covers on roof maintenance in North Hollywood, 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 North Hollywood.
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 North Hollywood
North Hollywood takes the full inland summer with very little relief after dark, and the ultraviolet load on a south-facing slope here is as hard as anywhere in the county. Asphalt ages from the top down under it: once the granules have gone the mat underneath turns brittle and starts to crack. Mostly single-storey post-war housing with later additions, which puts a transition detail in the middle of the roof where two eras of workmanship meet.
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 North Hollywood the thing to watch is granule loss on the sun-facing slopes, and the junction where an addition meets the original roof.
