What’s on your roof?

Different roofs. Same standard.

Know the details, because the details make the difference.

Slate-look shingle roof with a stone chimney, the coast behind.

Composition shingle

The common Bay Area roof. Most failures are details, not shingles.

Flat-tile hip roof on a hillside estate, the San Francisco skyline across the Bay.

Tile

Tile outlives the layer beneath it. A leak usually means the underlayment needs attention, not the tile.

Flat white roof of an office building with rooftop units, the city beyond.

Flat & low slope

The scarcest skill in this market. A seam or penetration fails long before the membrane.
