Higher gusts and uplift risk. We reinforce edge zones, starter/ridge systems, and replace weak flashings to prevent wind-driven leaks.
Best For: Wind ResistanceFlat roofs demand perfect drainage. We install TPO/modified bitumen systems with clean penetrations, curbs, and leak-first detailing.
Best For: Flat RoofingFog and moisture cycles can expose ventilation issues. We balance intake/exhaust and strengthen valleys, chimneys, and sidewalls.
Best For: Moisture ControlSouth San Francisco has two roofing realities: wind-exposed residential slopes and commercial flat roofs. We build both with the same discipline—details first.
Your roof is a system: underlayment, flashing, ventilation, drainage, and finish layer. We focus on the failure zones: edges, penetrations, transitions, and drains.

Valleys, chimneys, sidewalls, and penetrations sealed to a higher standard.
Drainage & Ponding Control
Flat roof drains, scuppers, and slope corrections where needed.
Wind Performance
Starter/ridge, edge zones, and fasteners aligned for uplift resistance.
