The rowhouse roof,
done properly.

Flat roofs fail at the details, not the field

The membrane in the middle of your roof is rarely the problem. Flat roofs die at the edges: parapet walls that wick water down into brick, scuppers that clog and pond, skylight curbs flashed with caulk and hope, and party-wall transitions where two buildings move differently. Our installs treat those details as the job — because they are.

We work in TPO, EPDM, and modified bitumen, and we'll tell you which suits your roof rather than pushing whatever's on the truck.

Drainage is everything

Water that leaves the roof never hurts it. We set tapered insulation where roofs hold water, rebuild scuppers and drop outlets, and size downspouts for real DC cloudbursts. If your roof ponds for days after rain, that's not "normal for flat roofs" — it's the first chapter of a leak story.

Skylights, decks, and penetrations

Rowhouse roofs carry skylights, vent stacks, HVAC, and increasingly roof decks. Every penetration is a future leak unless it's curbed and flashed into the system properly. We integrate them all — and if you're planning a roof deck, talk to us before the framing goes down, not after.
