What We See in Bel Air
Bel Air builds into its hillsides, which means the water problems live below grade as often as on the roof: subterranean garages, basement walls against saturated soil, and canyon lots taking runoff from every property above them.
The roof plan and the drainage plan have to be one plan here. When they are drawn separately, the hill usually wins.

We do not caption a job with a city we have not confirmed, so nothing here claims to be a Bel Air address. It is our crews, on our work, doing the thing described above.

Bel Air Questions
The hill is draining through your wall. Hillside lots take water under pressure from uphill, and a below-grade wall without an intact membrane and working drainage shows it as damp patches, efflorescence, or standing water. Where the wall can be exposed we membrane it directly; where it cannot, we intercept the water with drainage so it stops arriving. The diagnosis goes in the written scope.
Yes. On a canyon lot the roof is only part of the story — runoff from the slope above has to be caught and moved deliberately, or it finds the house. French drains, area drains, and sump systems are part of our waterproofing scope, and we design them alongside the roof plan rather than as an afterthought.
It changes two things: the specification, and what your maintenance is actually for. Canyon parcels here are routinely inside the severity zones the state maps at its top tier for wildfire, and that obliges a Class A rated roof plus closed detailing wherever the roof can draw air in. But the part worth remembering between now and the next storm is simpler and costs nothing. The leaf and needle litter that packs into a valley and pushes water sideways under the tile is the identical litter that would give a wind-carried ember somewhere to settle and smolder. Clearing it serves both purposes at once, which makes it the single highest-value hour anyone spends on a canyon roof.
