Triple Manufacturer Certification

Neighborhood Solutions

South San Francisco roofing tailored to wind, fog, and flat-roof corridors

Sign Hill & Hillside Zones

Higher gusts and uplift risk. We reinforce edge zones, starter/ridge systems, and replace weak flashings to prevent wind-driven leaks.

Best For: Wind Resistance

Lindenville & Industrial

Flat roofs demand perfect drainage. We install TPO/modified bitumen systems with clean penetrations, curbs, and leak-first detailing.

Best For: Flat Roofing

Westborough & Sunshine Gardens

Fog and moisture cycles can expose ventilation issues. We balance intake/exhaust and strengthen valleys, chimneys, and sidewalls.

Best For: Moisture Control

South San Francisco Systems

Shingle + Flat Roofing Mastery

South 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.

  • High-wind shingle install + sealed edges
  • TPO / Modified Bitumen flat systems
  • Drainage upgrades + leak-first detailing

Roofing Snapshot

Leak-First Detailing

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.

Mastering South San Francisco Roof Details

Roof failures usually start at details—flashings, penetrations, edges, and drains. We build and repair roofs to stop leaks at the source.

01. Flashing Discipline

Chimneys, walls, skylights, and penetrations sealed and reinforced to prevent recurring leaks.

02. Flat Roof Drainage

We address ponding water, drain performance, and curb details that cause hidden water intrusion.

03. Wind-Resistant Edges

Edge zones and starter/ridge systems built to withstand gusts and protect the roof perimeter.
