Roofs down in the West Covina flats, you can walk. Up here, half the job is getting material onto the roof at all — the streets off Pathfinder Rd and Brea Canyon Rd drop away fast, and plenty of these two-story homes have a downhill side only a conveyor reaches.
Inside Diamond Bar Country Estates, the paperwork is the long pole: gate access, contractor registration, then Architectural Committee sign-off on tile profile, ridge cap and color. Concrete tile runs the rest of the city too — 70s-through-90s tract stock — so most jobs are a lift-and-relay with new underlayment, not a tear-off. Nobody's hauling tile up Grand Ave at 4 PM, so deliveries work around the 57/60.
Tile, hillside access and the ARC in Diamond Bar
Do I need Architectural Committee approval to reroof in The Country?
Inside the gated Country Estates, yes. The committee controls tile profile, ridge cap and color, so pick your tile early and let approval and material lead time overlap.
My tile roof leaks but the tile looks fine. What's failing?
Almost always the underlayment. Tile lasts decades; the felt under it doesn't. We stack the tile off, replace underlayment and flashing, then relay the original tile wherever it's sound.
