Roofing Subcontractor for General Contractors

A Roofing Sub That Works Inside Your Schedule

Spartanburg's construction pipeline runs from new industrial build-to-suit projects along I-85 to retail and healthcare tenant work closer to downtown. We work as a roofing subcontractor to general contractors on new construction, additions, and reroofing scopes tied to larger renovation jobs, and we know the difference between working alone on a roof and working as one trade in a sequence of many.

Bid Packages and Estimating Turnaround

We provide itemized bid packages that break out membrane, insulation, flashing, and accessory scope separately so your estimator can compare against other subs cleanly. Takeoffs are done from drawings or a site walk, whichever the project stage calls for, and we flag ambiguities in the roof spec before bid day instead of leaving them for a change order later.

When a project moves fast, we can turn a budget number quickly and follow with a firm bid once drawings are issued for construction. We'd rather flag a schedule risk during preconstruction than discover it once steel is up and the roof is the next trade in line.

Submittals and Spec Compliance

Architect-specified roof systems come with submittal requirements: manufacturer data sheets, wind uplift calculations, fire rating documentation, and shop drawings for flashing details. We prepare and submit these on the timeline your project schedule requires, and we track revisions through the architect's review cycle so submittal delays don't become the reason the roof falls behind.

• Itemized bid packages broken out by scope for clean comparison
• Submittal packages prepared to match architect spec requirements
• Schedule coordination with steel, mechanical, and other rooftop trades
• Daily manpower reporting on multi-trade job sites when required
• Punch list turnaround tracked against project closeout dates
• Warranty and closeout documentation delivered to GC and owner

Sequencing With Other Trades

Rooftop mechanical units, solar arrays, and communications equipment all compete for the same roof deck timeline. We coordinate curb placement and dry-in sequencing with the mechanical and electrical subs on a job so nobody is waiting on a roof that isn't ready, and so we're not flashing around equipment that was set before we had a chance to review the layout. On new construction, getting the building watertight early protects interior trades from weather delays, and we prioritize dry-in scope accordingly when a GC needs it.

Manufacturing and distribution projects in this market often move on aggressive schedules tied to a tenant's opening date. We staff crews to match that pace when the schedule calls for it, without cutting installation steps that affect the manufacturer warranty.

Change Orders and Field Conditions

Existing-building reroofing tied to a larger renovation frequently uncovers deck conditions that weren't visible from drawings, rotted substrate, undersized drains, or prior repair patches that don't meet current code. We document these conditions with photos and a written scope description before proceeding, so the change order process moves quickly and doesn't stall the rest of the project.

We also flag conflicts between the roof spec and field conditions early, rather than installing to a spec we know won't perform, and rather than making a unilateral change that creates a dispute at closeout.

Safety and Site Requirements

Multi-trade job sites have their own safety plans, orientation requirements, and insurance documentation demands. We complete site-specific safety orientation, carry the certificates of insurance your project requires, and follow the GC's fall protection and site access rules rather than defaulting to our own standard procedure when it conflicts with the job's site plan.

Closeout and Warranty Handoff

At project completion we deliver manufacturer warranty documents, as-built flashing details, and material data sheets formatted for the owner's facilities file. We coordinate directly with the GC's closeout process rather than treating roof documentation as a separate track that shows up late.

Working Industrial and Retail Projects Across the County

The mix of work available to a roofing sub in this market runs from build-to-suit industrial shells near Duncan and Wellford to tenant improvement and reroofing scope on retail and office buildings closer to downtown Spartanburg. Each project type carries different scheduling pressure. A build-to-suit industrial project is usually driven by a tenant's occupancy date, which makes dry-in speed the priority. A retail tenant improvement is usually driven by store-opening deadlines and requires closer coordination with interior trades working underneath an active roof crew.

We staff and schedule differently depending on which type of project we're bidding, and we tell a GC upfront if a schedule assumption in the bid documents doesn't match what we think is realistic given current material lead times or crew availability, rather than agreeing to a date we don't expect to hit.

Common Questions From GCs and Estimators

Can you turn a bid quickly for a fast-track project?

Yes. We can provide a budget number early and follow with a firm itemized bid once construction drawings are released, and we'll tell you upfront if the schedule is tight enough to affect material lead times.

Do you handle submittals for architect-specified systems?

Yes. We prepare manufacturer data sheets, uplift calculations, and shop drawings to match the spec, and track them through the architect's review and revision cycle.

How do you coordinate with mechanical and electrical trades on the roof deck?

We review curb and penetration layouts with the other rooftop trades before dry-in begins, so equipment isn't set before flashing details are finalized around it.

What happens if you find bad deck conditions during a reroof?

We stop, document the condition with photos, and submit a written change order description before proceeding, so the GC and owner can approve the added scope without delaying the rest of the project longer than necessary.

Can you meet a multi-trade site's insurance and safety orientation requirements?

Yes. We carry standard commercial general liability and workers' comp coverage and complete whatever site-specific safety orientation your project requires before crews mobilize.
