Roofing

HVHZ certification, flashing detail, and warranty registration — a roof failure shows up 5 years later, long after the homeowner review.

What this trade is

Roofing covers tear-off, decking inspection, underlayment, flashing, ice-and-water shield, and finish roof (asphalt, tile, metal, TPO/EPDM for flat sections). Flashing detail at valleys, wall intersections, and penetrations is the quality signal — 90% of roof leaks are flashing failures, not field failures.

Why a GC needs a verified roofing sub

Roofing subs carry significant liability — a roof installed during a remodel is often warranted back to the GC of record. A GC with a stable roofing sub has consistent warranty coverage and predictable flashing details across projects. In HVHZ jurisdictions (Miami-Dade and Broward in Florida) the sub must hold current HVHZ certification.

Regulatory landscape

License structure varies by jurisdiction. AskBaily verifies against the licensing authority that applies to the project location — not the GC's headquarters. A few representative jurisdictions:

  • California — CSLB
    C-39 (Roofing)

    C-39 specialty license for roofing. Chapter 7A applies in Wildland-Urban Interface.

    CSLB→
  • Florida HVHZ — Miami-Dade + Broward Product Control
    Roofing Contractor + HVHZ product approval

    Miami-Dade and Broward impose High-Velocity Hurricane Zone product approval on all roofing assemblies. Subs must use HVHZ-approved products + install per Notice of Acceptance.

Quality signals AskBaily tracks

Each declared sub accumulates these signals across projects. They appear on the sub's digital twin and on the GC's public sub-trade view.

  • HVHZ certification (FL only)

    Required in Miami-Dade and Broward. Tracked on the twin for FL pros.

  • Manufacturer-warranty registration rate

    Percentage of installs registered for extended manufacturer warranty — a discipline signal.

  • Flashing-failure callback rate

    Callbacks traced to flashing install, tracked over 5-year window.

Cross-trades

Roofingsits at the edge of several other trades. Coordinated scheduling between these is the GC's core responsibility; the sub-trade graph makes the coordination visible across projects.

Framing
Framing sets every dimension that follows. Mistakes here compound for the rest of the project.
Masonry & Concrete
Concrete cures once. Foundations, slab pours, and retaining walls do not forgive mistakes.
Painting
The finish everyone sees. Prep discipline and product selection separate a 2-year finish from an 8-year finish.
