Roofing subcontractors install the assemblies that seal and weatherproof a building: underlayment, shingles, tile, metal panels, low-slope membranes, and the flashings that tie them into walls and penetrations. General contractors and builders bring a roofer in at a pivotal point in the schedule, because dry-in gates almost everything inside the building. On steep-slope work the scope often lands in two mobilizations: dry-in right after the roof deck passes its nailing inspection, then the finish roof once the building can accept material loading, which on tile jobs also means coordinating crane or conveyor time. Until the roof is dried in, drywall, insulation, and most finishes are exposed, so a roofer who hits the dry-in window protects the whole downstream schedule. Coordination pitfalls concentrate at penetrations: HVAC curbs, plumbing vents, solar mounts, and anything another trade cuts through the roof after the roofer leaves. Since new California homes generally require photovoltaic systems, agree early on who flashes the solar attachments and who owns a leak at them. In California, product selection also runs through Title 24, which sets aged reflectance and emittance minimums for cool roofs, stricter on low-slope than steep-slope, with compliance products rated through the CRRC directory. In designated fire hazard severity zones, Chapter 7A requires Class A roof assemblies, so confirm the rating applies to the specified assembly rather than the shingle alone. Ask bidders what their workmanship warranty covers separately from the manufacturer's material warranty, and whether the manufacturer's enhanced warranty programs require an installer credential. Before award, we recommend confirming license and insurance status: California roofing work typically falls under the CSLB C-39 Roofing classification, with a free public lookup at cslb.ca.gov. Texas has no statewide roofing license; registration is municipal where required, and the RCAT credential is voluntary.
As soon as the roof deck is complete and any required deck nailing inspection has passed, because dry-in gates insulation, drywall, and interior finishes. On tile and some metal roofs plan a second mobilization for the finish roof, including crane or conveyor time for loading. Treat the dry-in date as a critical path milestone and confirm the sub can hold it before award.
The California Energy Code sets minimum aged solar reflectance and thermal emittance values for roofing on new construction and most reroofs, with stricter reflectance thresholds on low-slope roofs than steep-slope. Products used for compliance need a Cool Roof Rating Council rating, so confirm the specified product appears in the CRRC directory before ordering material.
In mapped fire hazard severity zones, Chapter 7A of the building code requires roof assemblies with a Class A fire rating. The rating applies to the assembly as tested, not the shingle alone, so verify the full assembly including underlayment matches a listed Class A configuration for the project location.
This is one of the most common sources of roof leak disputes. HVAC, plumbing, and solar crews routinely penetrate a finished roof, and if the roofer does not flash those penetrations the workmanship warranty usually excludes them. Sequence penetrations before the roofer demobilizes where possible, and put in the subcontract that the roofer returns to flash late penetrations.
The manufacturer's warranty covers material defects, while workmanship is warranted by the installing contractor, and enhanced manufacturer warranties that add workmanship coverage typically require the roofer to hold that manufacturer's installer credential. Ask each bidder what their own workmanship warranty covers, for how long, and whether the specified system qualifies for an enhanced warranty with them installing it.
We recommend confirming the license classification and status where one applies (in California, CSLB C-39 Roofing, with a free public lookup at cslb.ca.gov), current liability and workers' comp insurance, and fall protection practices. Texas has no statewide roofing license, so check municipal registration requirements and note that the RCAT credential there is voluntary.
