Sealant Life on Burbank Roofs — The Short Answer
What you can check on roof maintenance in the Valley from the ground, from the driveway and the attic.
You can learn a lot about a roof without going anywhere near it, and none of the checks worth doing require climbing. This is what to look at on roof maintenance in the San Fernando Valley, safely, from the ground.
What you can check yourself
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.
What to leave alone
Stay on the ground and use the attic. Binoculars from the driveway and a torch in the roof space find nearly everything worth finding. Timing matters more than frequency. One visit in late autumn, before the rains arrive, is worth more than three spread randomly across the year. As soon as you find something you cannot explain, stop looking and get it assessed.
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.
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
What can I check from inside?
A great deal. The attic shows staining, daylight through the deck and ventilation problems long before anything appears on a ceiling.
When do I stop looking and call somebody?
As soon as you find anything you cannot explain, and immediately if there is any sign of water inside.
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.
