N°07 — Sub-Hub Trade Bids
Roofing Bids for Subcontractors
$39/mo after a 7-day free trial. Card required, no charge today. Cancel anytime.
Roofing bid opportunities are not limited to one phrase. Public owners and general contractors describe the same work as roofing, reroof, roof replacement, TPO, membrane, built-up roof, shingles, flashing, coping, insulation, underlayment, gutters, or leak repair work. A useful roofing bid page has to watch those terms together, not as separate searches.
ConstructionBids.ai monitors 12,500+ public bid portals and helps subcontractors turn that spread of source language into a workable daily search. Sub-Hub Free lets roofing firms start without a credit card. Sub-Hub Pro adds the full match-score breakdown, AI scope analysis, alerts, saved bids, and document access for $39/mo after a 7-day free trial.
Use this page as a reference for where roofing bids appear, how GC bid invitations usually reach roofing subs, and what to prepare before asking to be added to a GC bid list.

N°04 — Beyond Public Portals
How GCs invite roofing subs
Sub-Hub itself lists direct public solicitations. The notes below cover the separate GC-invitation channel that runs alongside them, and how to get on those lists.
GC roofing invitations usually start from a bidder list built around roof-system experience, manufacturer certifications, safety record, service geography, bonding capacity, and whether the project is replacement, repair, or new construction. The invitation can arrive from a plan room, bid management platform, direct estimator email, or a facilities and maintenance bidder list.
Roofing scopes are often split across tear-off, substrate repair, insulation, membrane, shingles, flashing, coping, sheet metal trim, gutters, roof accessories, and warranty requirements. Smaller projects may bundle the full reroof. Larger schools, civic buildings, and facility programs may separate roof areas, alternates, or manufacturer systems so the GC can level coverage and warranty terms.
The best response confirms roof system, manufacturer, warranty, tear-off assumptions, moisture testing, deck repair allowances, safety plan, weather assumptions, and phasing. GCs want a clear position on penetrations, curbs, temporary dry-in, occupied-building access, and addenda that change roof details or square footage.
N°05 — Bid Better
Win more of the right bids
- Search beyond roofing. Include reroof, roof replacement, TPO, membrane, built-up roof, shingle, flashing, coping, gutter, leak repair, and roof insulation terms.
- State weather, temporary dry-in, occupied-building protection, material storage, and seasonal production assumptions when rain, wind, or temperature can affect work.
- Confirm manufacturer certification, warranty requirements, uplift ratings, insulation thickness, substrate repairs, moisture scans, and deck replacement allowances.
- Separate membrane, flashing, sheet metal, gutters, roof accessories, and Division 07 waterproofing details when the specifications blur scope boundaries.
- Check addenda for roof area changes, detail revisions, penetrations, curb work, flashing heights, alternate systems, and warranty language.
- Explain safety plan assumptions for fall protection, access, staging, crane or lift use, and occupied-site coordination before the GC levels your quote.
N°06 — How to Bid
How to Bid Roofing Work on Public Projects
- Step 01
Find public roofing solicitations
Search city, county, school district, higher education, housing authority, facility, SAM.gov, and state procurement portals for roofing, reroof, roof replacement, TPO, membrane, built-up roof, shingles, flashing, coping, gutters, insulation, leak repair, and roof accessories. Also monitor plan rooms where GCs invite roofing subs on facility renovations.
- Step 02
Read Division 07 requirements
Review Division 07 thermal and moisture protection, roof plans, details, addenda, alternates, and manufacturer requirements. Confirm tear-off, substrate repairs, insulation, membrane, flashing, coping, sheet metal, gutters, penetrations, curbs, moisture scans, temporary dry-in, warranty term, uplift rating, and whether related waterproofing is included.
- Step 03
Confirm eligibility and warranties
Check registration, insurance, bonding, safety, prevailing-wage, certified-payroll, manufacturer certification, warranty authorization, and occupied-site requirements before estimating. Public roofing jobs often require proof that the installer can provide the specified system warranty, follow fall-protection requirements, and coordinate work around school or facility operations.
- Step 04
Estimate roof system and access
Price tear-off, disposal, deck repair allowances, insulation, membrane or shingle system, flashing, sheet metal, gutters, accessories, safety, lifts, cranes, staging, material storage, temporary protection, and weather risk. State assumptions for moisture testing, deck replacement, penetrations, phasing, occupied-building protection, and seasonal production.
- Step 05
Submit with manufacturer and scope clarity
Follow the bid form, addenda, alternates, bonds, certifications, and upload instructions exactly. For GC invitations, send a scope letter naming roof system, manufacturer, warranty, inclusions, exclusions, phasing, safety assumptions, temporary dry-in, roof area basis, and who owns curbs, penetrations, sheet metal, deck repairs, and testing.
- Step 06
Track awards and warranty questions
After bid day, review tabulations, awards, and GC leveling questions. Roofing bids are often leveled around warranty compliance, system substitutions, deck repair allowances, safety, phasing, and occupied-building access. Capture those issues so future Division 07 bids separate warranty and weather risk earlier.
N°07 — FAQ
Roofing bid questions
Where can roofing subcontractors find public bids?
Roofing subcontractors can find public bids on city, county, state, school district, higher education, housing authority, facility, and federal procurement portals. Search NAICS 238160 with scope words such as roofing, reroof, roof replacement, TPO, membrane, built-up roof, shingles, flashing, coping, gutters, and leak repair.
How do roofing subcontractors get on GC bid invitation lists?
Start with a concise capability profile, insurance certificates, bonding capacity, service area, safety contact, manufacturer certifications, warranty capabilities, project-size range, and relevant public-project references. Tell estimators whether you pursue low-slope, steep-slope, service repair, reroof, sheet metal, or full Division 07 roofing packages.
Do roofing subcontractors need bonding for public work?
Bonding depends on project size, owner rules, and the GC's subcontract requirements. Public roofing work can involve material, warranty, safety, and occupied-building exposure, so GCs may ask for bonding capacity, a consent of surety, or proof that the firm can support the package.
What prequalification documents do GCs usually ask roofing subs for?
Common prequalification items include insurance certificates, safety history, EMR or OSHA information, bonding capacity, references, project-size range, financial information for larger packages, manufacturer certifications, warranty credentials, safety procedures, and similar low-slope, steep-slope, or reroof experience.
What project scopes are typical roofing bid opportunities?
Typical scopes include reroofing, TPO, EPDM, PVC, built-up roofing, shingles, underlayment, insulation, flashing, coping, gutters, downspouts, roof accessories, leak repair, deck repair allowances, moisture testing, temporary dry-in, and roofing work tied to schools, civic facilities, housing, utilities, and facility maintenance.
What NAICS code should roofing contractors use for bid searches?
The core NAICS code is 238160, Roofing Contractors. Use the code with text searches because many bid portals do not tag opportunities consistently by NAICS, especially when reroof, membrane, TPO, flashing, shingle, and repair scopes are listed separately.
How large are roofing subcontractor bid packages?
Roofing packages can range from small leak repairs and flashing replacements to full occupied-building reroofs with tear-off, insulation, membrane, sheet metal, access, safety, and warranty requirements. Review drawings, specifications, addenda, bonding requirements, weather exposure, material availability, and phasing before deciding whether the package fits your capacity.
Can Sub-Hub help roofing subs without a credit card?
Yes. Sub-Hub Free has no credit card requirement. Roofing subcontractors can start with bid discovery and upgrade to Sub-Hub Pro when they need full score breakdowns, alerts, saved bids, document access, and AI scope analysis.
How do roofing contractors bid public jobs without GC invites?
Start with public owner portals, SAM.gov, school district bids, housing authority listings, facility procurement pages, and plan rooms. Then contact bidding GCs with manufacturer certifications, warranty capabilities, safety information, service area, references, and bonding capacity.
What roofing warranty details should I check before bidding?
Read Division 07, manufacturer requirements, roof details, alternates, and addenda for warranty term, installer certification, uplift rating, membrane or shingle system, insulation, flashing, substrate repairs, and exclusions. Confirm the specified warranty can be issued by your firm before pricing.
