Building envelope subcontractors close the structure against water, air, and weather: roofing contractors and roof repair services on top; stucco and siding contractors on the walls; window and door installers at the openings; and waterproofing and rain gutter contractors handling below-grade membranes, deck coatings, and drainage. For a general contractor or builder, the envelope phase sits between framing sign-off and interior finishes, and its defining risk is sequencing: flashing, weather-resistive barriers, and window installation have to integrate in the right order, because most construction-defect claims trace back to transitions between trades rather than to any single product. A roofer, a stucco crew, and a window installer can each perform their scope correctly and still leave a leak if the laps and flashing sequence at the head and sill were never coordinated, so it pays to walk those details with all envelope subs together before lath or housewrap goes on. Roof dry-in typically comes first so interior trades can start; windows and exterior doors follow, then the wall cladding, with gutters and final waterproofing details at the end. In California, stucco over two-coat or three-coat lath systems remains the dominant cladding, Title 24 energy code drives window U-factor and cool-roof requirements, and wildfire-zone (WUI) projects add ignition-resistant requirements for roofing, vents, and siding; Texas projects deal more with wind ratings and hail-rated roofing. Before contracting, we recommend confirming that each sub's license classification matches the work, since in California roofing typically falls under CSLB C-39, plastering under C-35, and glazing under C-17, and that their liability insurance is current; California's CSLB offers a free public license lookup. Texas does not license these trades at the state level, so verification there runs through city contractor registration, insurance certificates, and references. For waterproofing scopes especially, ask who owns the warranty across trade boundaries and whether the manufacturer requires a certified installer for the specified membrane system.
A common sequence is roof dry-in first so interior rough trades can proceed, then windows and exterior doors, then the weather-resistive barrier and cladding (stucco lath or siding), with rain gutters and finish waterproofing details last. The exact order matters less than agreeing on the flashing sequence at every transition before the first envelope sub starts.
Review whether the bid matches the specified assembly (underlayment, ventilation, cool-roof compliance where required), whether the roofer holds the manufacturer certification the specified warranty requires, and whether that warranty is conditioned on documented maintenance after turnover. We recommend confirming liability and workers' compensation coverage are current, and in California that the C-39 license is active via the free CSLB lookup; Texas has no statewide roofing license, so registration and references carry more weight there.
Assign one party clear responsibility for the water management plan, either a dedicated waterproofing contractor or the GC's superintendent, and have every envelope sub's flashing tie into it. Split accountability at trade boundaries is the most common root of envelope leaks and the hardest to resolve after a failure.

Order long-lead window and door packages as soon as openings are confirmed at framing, since custom and energy-code-compliant units can carry lead times of several weeks to a few months. Late windows stall the cladding, which in turn stalls insulation and drywall inspection inside.
It varies by scope. The main drivers are roof area and pitch, cladding type (three-coat stucco versus one-coat systems versus siding), window count and performance specification, waterproofing complexity at decks and below-grade walls, and access or staging conditions. Energy-code and WUI requirements in California can also move the specification meaningfully.
