Solar + Roofing Quote Checklist: Compare Both Scopes

A useful solar roofing quote checklist keeps roofing and photovoltaic work separately understandable even when one company sells, finances, or manages both. Normalize the roof assembly, PV design, prices, milestones, changes, warranties, and responsible legal entities before comparing totals. A single contract can coordinate well; two contracts can coordinate well. Neither structure protects you unless every handoff is written.

This guide is for a New England homeowner who has decided to price roof work with solar, not someone still deciding whether the roof needs replacement. Teamsun offers a solar and roofing project discussion, but its current project scope, roofing products, contractors, licenses, flashing details, warranties, pricing, and schedule must be confirmed in a written proposal. Apply this worksheet to Teamsun and every other bidder.

The 60-second rule: Do not compare a blended total. First write down a gross cash roof price, gross cash solar price, separately priced electrical or other work, and the gross combined price. Then reconcile each number to its scope, financing documents, tax assumptions, responsible party, acceptance evidence, and change-order rule. If the four numbers cannot be reproduced from the documents, pause.

What must a combined solar and roofing quote show?

A signable quote must expose two complete construction scopes and the interface between them. It should let a second contractor, building official, lender, warranty reviewer, or future service provider identify what is being installed, by whom, for what price, in what sequence, and under which acceptance test.

Use this first-pass checklist before reading warranty headlines or monthly payments:

Required section	Minimum written evidence	Pause when
Contract identities	Seller, roof contractor, solar contractor, electrician, permit applicants, lender/system owner	A brand or division appears without its legal entity
Separate cash prices	Roof, solar, and other scopes; total reconciles	Only one bundled price or monthly payment appears
Roofing assembly	Tear-off, exact covering and accessory products, underlayment, leak barrier, flashing, ventilation, decking rules	“Architectural shingles” or “complete roof” is the specification
Solar system	Exact models, quantities, DC/AC ratings, layout, production inputs, attachments, electrical scope	“Premium panels” or an unapproved “equivalent” can replace the design
Unknown conditions	Investigation, evidence, allowance or unit price, approval, deadline, decline path	“Additional work as needed” has no control
Responsibility interface	Roof-to-PV measurement, penetrations, vent moves, sequence, dry-in, inspections, leak response	Each contractor disclaims the other’s work
Milestones	Evidence required before each payment and final acceptance	“Installation complete” is undefined
Warranty/service	Provider, covered work, labor/access/removal, exclusions, claim route, transfer	One long term is presented as complete coverage
Closeout	Inspections, utility authorization, as-builts, product records, registrations, monitoring, releases as applicable	Final payment is due before the promised records exist

The Federal Trade Commission’s home-improvement guidance says written estimates should describe the work, materials, completion date, and price, and it advises buyers to fill blanks and avoid paying the full amount upfront. The Department of Energy’s installer guide specifically tells solar buyers to ask whether a roof needs repair, who is responsible for damage or leaks, whether subcontractors are used, and whether roof repair or vent relocation is in the proposal.

Those are minimum controls. A combined project also needs a written bridge between the roof specification and the array design.

Is one combined contract better than two coordinated contracts?

Choose the structure with the clearer enforceable responsibility, not the smaller number of signatures. One prime agreement can reduce commercial handoffs, but it may still contain separate affiliates, subcontractors, warranties, and lender documents. Two coordinated contracts can preserve specialist selection, but the owner may carry more scheduling and interface risk.

Decision	One prime contract	Coordinated roof and solar contracts
Who receives payment?	Prime entity; exhibits must show allocation and any direct third-party payment	Each contractor under its own schedule
Who owes completion?	Prime should accept responsibility for included subcontracted scopes	Each contractor owes its defined scope; coordination duty must be assigned
Who controls sequence?	Named prime project manager	Named coordinator—owner, roofer, solar contractor, or third party
Who resolves a scope gap?	Prime contract’s inclusion, exclusion, and change clauses	Interface exhibit signed or acknowledged by both contractors
Who responds to a leak?	One intake path can help, but cause review and remedies still need terms	First-response and investigation process must prevent immediate finger-pointing
What if one party closes?	Subcontractor failure may remain the prime’s risk only if contract says so	Remaining contractor is not automatically responsible for the other
What is the finance boundary?	Lender principal must reconcile to separately stated scopes	Separate financing may make allocation clearer but adds documents

Require one contract reconciliation page regardless of structure:

1. List every agreement, addendum, disclosure, warranty, and finance document by title and date.
2. Identify the legal party and payment amount in each.
3. State which document controls if terms conflict.
4. Confirm that a roofing contract does not create a second charge already included in a solar contract.
5. State whether cancellation, default, or delay in one scope affects the other.
6. Attach the same roof plan, solar layout, responsibility matrix, and milestone schedule to the controlling agreements.

This is not theoretical. Homeowners in forum discussions repeatedly ask whether a separately issued roof agreement duplicates a price already embedded in a solar contract, and whether verbal roof promises are enforceable when the solar agreement contains only PV detail (combined-contract discussion, missing roof-scope discussion). These threads inform the worksheet; anonymous comments are not legal or technical evidence.

Which roofing line items make two bids comparable?

A roof price is comparable only after the assembly and unknown-condition rules match. “Same shingle brand” is not the same roof. The quote should identify the covering, every promised accessory layer, preparation, metalwork, ventilation, disposal, site protection, warranty tier, and what happens when tear-off exposes damaged decking.

Roofing assembly schedule

Ask each bidder to complete every row, writing “not applicable” rather than leaving blanks.

Roof component or task	Detail the quote must state	Bid A	Bid B
Measurement basis	Roof area/squares, slopes, stories, pitch, planes, waste basis	___	___
Tear-off	Number/type of existing layers, disposal, dump fees, daily cleanup	___	___
Deck	Existing type/thickness if known; inspection; fastening; replacement unit and measurement	___	___
Covering	Manufacturer, product line/model, profile, color, rating represented in documents	___	___
Leak barrier	Exact product and locations: eaves, valleys, penetrations, other areas	___	___
Underlayment	Exact product, coverage, fastening, exposure limits if relevant	___	___
Starter and ridge	Exact starter, hip/ridge, ridge-cap, and related accessory products	___	___
Edge and metalwork	Drip edge, valleys, step/counter flashing, chimney, wall, skylight, pipe boots	___	___
Ventilation	Existing intake/exhaust assessment; retained, blocked, removed, or added products	___	___
Rooftop objects	Vents, antennas, satellite dishes, gutters, skylights, HVAC, chimneys	___	___
Solar interface	Attachment family/basis, flashing or waterproofing method, standoff timing, marked no-go zones	___	___
Site protection	Landscaping, siding, driveway, attic/interior, debris and magnetic sweep	___	___
Weather plan	Tear-off limits, overnight dry-in standard, emergency covering and notice	___	___
Warranty package	Manufacturer document, eligible system components, contractor workmanship, registration	___	___
Exclusions	Fascia, soffit, gutters, chimney, skylight, mold, hazardous materials, interior repair	___	___

Manufacturer documents show why generic labels fail. The current Owens Corning roofing document library separates shingles, leak barriers, underlayments, starter, hip/ridge, ventilation, deck requirements, installation instructions, and warranties. Its RhinoRoof U20 instructions also condition installation on a prepared, dry, structurally sound deck and applicable codes. This does not recommend Owens Corning or establish a product for your home. It demonstrates that “roof system included” is too vague to audit.

Decking allowance test

Concealed deck deterioration can be a legitimate unknown. Do not force a contractor to guess its quantity; control the price method. Record:

• included sheets or board quantity, if any;
• price per defined sheet, square foot, or linear foot beyond that allowance;
• material grade and thickness;
• who photographs and measures removal;
• who may approve work and how quickly the owner must respond;
• whether framing, hazardous material, or widespread replacement triggers a separate pause; and
• how the final quantity appears on the revised contract and invoice.

An allowance already included in a fixed roof price must not be added twice. If R is the fixed roof price, A is the decking allowance within R, and V is the verified cost under the agreed rule, the arithmetic-only reconciliation is revised roof price = R + (V − A). The letters are blank project inputs, not a Teamsun price or prediction.

Which solar line items must remain separate from roofing?

Keep PV design, equipment, production, electrical, interconnection, and commissioning visible even if one loan or invoice covers both projects. The roof is an enabling construction scope; it is not a substitute for a final solar design.

Solar scope	Required proposal evidence	Interface with roofing
Array	Exact module model, quantity, watts, total DC kW, dated layout	Same roof planes, vents, setbacks, obstructions, and measurements
Inverter system	Exact model(s), count, architecture, AC rating	Equipment locations and roof/conduit paths coordinated
Mounting	Racking and attachment family or final-selection basis; roof-type assumption	Roofer accepts penetrations/flashing conditions in writing where needed
Production	Year-one kWh estimate plus shade, weather, orientation, loss and degradation inputs	Layout revisions after reroof must update the estimate
Electrical	One-line, connection method, panel/service work, routes, disconnects, monitoring	Any roof/attic access and conduit penetrations assigned
Structural	Survey inputs, design criteria, reinforcement decision path	Deck replacement does not replace structural analysis
Municipal	Plan preparation, building/electrical permits, revisions and inspections	Identify whether roof permit is separate or combined locally
Utility	Interconnection application, study/upgrade treatment, completion filing, authorization	Roof completion is not permission to operate
Commissioning	Configuration, functional checks, owner monitoring account and records	Final roof punch list is a separate acceptance event
Closeout	Final models/serials, as-built, manuals, warranties, permits, inspection, utility evidence	One indexed package includes both trades without blending remedies

The DOE explains that rooftop solar generally moves through local permitting and inspection; exact requirements vary by jurisdiction. The quote should therefore assign application, correction, reinspection, and closeout responsibility without promising an authority’s timing or approval.

For roof attachments, require the final approved design and applicable manufacturer instructions. A current IronRidge XR installation manual, for example, has roof-cover-specific attachment instructions. It is evidence that attachment details depend on the selected system and roof, not evidence that Teamsun uses IronRidge or that this product suits a particular property.

If your bids differ beyond the roof scope, use the solar quote contents checklist and apples-to-apples solar comparison for the deeper PV comparison. B200’s narrower job is keeping the roof package and its interface from disappearing inside the solar total.

How should roof-to-solar responsibilities be assigned?

Every overlap needs a first responder, decision owner, cost rule, and acceptance evidence. The matrix can name a prime contractor or two separate contractors. “Coordinate as needed” is not an assignment.

Overlap event	First responder	Decision owner	Price/change rule	Acceptance evidence
Final roof measurement conflicts with solar layout	___	___	Redesign included / defined change: ___	Revised roof plan, layout, production report
Vent or obstruction conflicts with array	___	___	Retain / move / redesign; price: ___	Signed detail and permit plan
Deck damage appears at tear-off	___	___	Allowance/unit rule: ___	Photos, measured quantity, written approval
Structural concern appears	___	Engineer/AHJ as applicable: ___	Retainer and repair responsibility: ___	Written finding and revised design
Standoff or attachment timing changes	___	___	Mobilization/rework rule: ___	Approved sequence and installation record
Roof is exposed when weather changes	___	___	Emergency protection responsibility: ___	Dry-in inspection/photos and notice
Permit correction touches both scopes	___	Permit applicant/design authority: ___	Error versus owner/authority change: ___	Approved revision and passed inspection
Leak appears near array	One intake contact: ___	Cause-review process: ___	Access/removal/repair/interior treatment: ___	Service report and remedy closeout
Solar equipment must be removed for roof warranty work	___	___	Labor, storage, reinstallation, recommissioning: ___	System restored and monitoring verified
One contractor delays the other	___	Project coordinator: ___	Notice, resequencing, storage, extension: ___	Updated accepted schedule

The matrix must not predetermine fault. Its purpose is to prevent an exposed roof, leak, failed inspection, or idle crew from waiting while two parties debate whose scope starts first.

If you want a bidder to complete this matrix against a specific property, discuss your roof and solar project with Teamsun. Treat the reply as proposal evidence, not proof of a universal Teamsun crew model, roofing system, warranty, or schedule.

What makes a valid change order for a combined project?

A change order is valid for comparison only when it updates scope, price, time, design, financing, and both trades’ responsibilities before changed work proceeds. A legitimate concealed condition is not a blank check; a design correction is not automatically an owner expense.

Run this seven-part test:

1. Trigger: What buyer request, concealed condition, official requirement, or approved substitution caused the change?
2. Evidence: Which site photo, measurement, product notice, engineering finding, permit correction, or utility document proves it?
3. Scope: What is added, deleted, or revised in the roof and solar exhibits?
4. Price: Is it a fixed amount, allowance reconciliation, or measured unit price? Does the new total add correctly?
5. Consequences: What changes in schedule, production estimate, roof warranty, PV warranty, financing, or cancellation right?
6. Authority: Which owner and contractor representatives can approve it?
7. Decline path: Does work pause, revert, resize, terminate, or proceed under another documented option?

State contract rules differ. Connecticut says covered home-improvement contracts must contain the entire work-and-price agreement and that changes must be written and specific (Connecticut DCP contract guidance). Massachusetts’ current home-improvement contract requirements call for a detailed work/material description, total price, dollar payment schedule including finance charges, permit clauses, warranty notices, and disclosure of a lien or security interest; use counsel for application to mixed solar/roof documents.

Rhode Island’s solar rule is unusually explicit: residential solar proposals/contracts must itemize additional charges including roof replacement or repair, and on request the retailer must provide detailed solar equipment, labor/design, and anticipated permit/application charges (230-RICR-30-45-1). The Rhode Island Attorney General likewise tells buyers to request a price breakdown and a contract stating who performs work and what is or is not included.

These sources do not make one three-state contract form safe everywhere. Have a qualified attorney review a high-value, financed, disputed, or unusual agreement.

How should financing and tax language treat the two scopes?

A lender may fund both scopes, but the construction prices must remain traceable. Record the roof cash price, PV cash price, combined cash price, down payment, amount financed, APR, finance charge, total of payments, disbursement recipients, security interests, payment changes, and prepayment terms.

The CFPB’s solar-financing issue spotlight recommends comparing cash price with loan principal because financing costs can be embedded in the amount financed. Do not put the difference into “roof” or “solar equipment” merely to force the figures to reconcile. Ask the lender and seller for a written explanation.

As of August 10, 2026, the IRS says the homeowner Residential Clean Energy Credit under §25D is not available for property placed in service after December 31, 2025. The same current IRS page says traditional roofing and structural components generally did not qualify under the former credit. Therefore, a new 2026 residential quote should not subtract a 30% §25D credit from solar, roof, or combined cost, and bundling the prices does not create eligibility.

Do not ask a salesperson to invent a tax allocation. Keep the construction scopes separate, preserve invoices and change records, and ask a qualified tax professional whether any current federal, state, business-use, insurance, rebate, basis, or other treatment applies to your facts. This guide provides no personalized tax conclusion.

Which payment milestones prove progress?

Pay against defined evidence, not vague percentages or a seller’s internal label. The exact lawful schedule depends on state, contract, custom materials, lender disbursement, and project facts. The worksheet below leaves amounts blank.

Milestone	Roof evidence before acceptance	Solar evidence before acceptance	Amount/due rule
Contract/deposit	Executed scope, material schedule, cancellation forms	Executed design assumptions, equipment schedule, cash price	___
Site verification	Roof measurement/condition record; open deck conditions listed	Survey, electrical/structural inputs, revised layout	___
Final design	Assembly and flashing/ventilation decisions	Final array, one-line, production model, attachment basis	___
Permits/procurement	Required roof application/status; exact ordered products	Required solar applications/status; exact ordered models	___
Tear-off/dry-in	Deck change record; verified weather-tight state	Approved interface locations preserved	___
Roof completion	Roof punch list, cleanup, warranty eligibility documents	Roof released for array work by named decision owner	___
Solar installation	Penetration/attachment record and roof-interface inspection	Defined mechanical/electrical completion	___
Inspection/commissioning	Roof permit corrections closed where applicable	Passed required inspections; commissioning and monitoring evidence	___
Utility authorization/closeout	Final roof records and warranty contacts	Utility authorization, as-built, serials, manuals, service contacts	___

Do not let “materials delivered,” “roof complete,” “solar installed,” “inspection passed,” and “permission to operate” collapse into one event. They describe different evidence. Connecticut recommends payments aligned to work progress, while Massachusetts says covered contracts over $1,000 need a written agreement and limits advance payment subject to its special-order exception (CT DCP guidance, Massachusetts HIC homeowner resources). Verify the current rule and applicability for the property.

At closeout, reconcile original prices plus every approved change to every payment and lender disbursement. Request receipts, permit and inspection records, product/warranty documents, as-builts, monitoring ownership, utility authorization, and lien notices or releases where applicable. Rhode Island’s contractor board specifically identifies a homeowner right to request applicable lien releases (RI CRLB homeowner notice); obtain state-specific legal advice elsewhere rather than assuming one form works regionwide.

If the roof sizes, materials, solar designs, or ownership/financing differ, do not force a price ranking. First request a revised matched bid or label the difference and decide whether it adds value.

Stop, pause, or proceed?

Proceed only when authority, scope, price, interface, change, payment, warranty, and acceptance evidence all reconcile. Use the gate after the site survey and again before final signature.

Gate	Decision
Stop	Duplicate or irreconcilable roof charge; hidden legal party; unlicensed/unverified required trade; blank price; pressure to misstate tax eligibility; work or payment demanded without controlling documents
Pause	Deck, structure, electrical service, product, permit, utility, finance, roof-warranty, or responsibility condition is unresolved but has an investigation and decision date
Proceed to legal/financial review	Exact scopes and prices reconcile; entities and roles are named; changes require evidence and authority; milestones match acceptance; warranties and closeout are documented

A “proceed” is not a guarantee of schedule, approval, savings, or workmanship. It means the proposal is complete enough to compare and take through any needed contractor, municipal, lender, insurance, tax, or legal review.

Frequently asked questions about solar and roofing quotes

Should roof and solar prices be separate in one contract?

Yes. Separate, reconciled prices preserve scope comparison, financing review, change control, warranty ownership, and tax review. They can sit in one prime agreement, but each amount should connect to a complete exhibit and the combined total should add correctly.

Do I need two contracts if a solar company subcontracts the roof?

Not automatically. Contract structure depends on the companies and law. Identify who contracts with you, who gets paid, whether the prime accepts responsibility for the roofer, and whether a second agreement adds obligations or only documents the included scope.

What roofing materials should the quote name?

Name the roof covering product, leak barrier, underlayment, starter, hip/ridge, ventilation products, edge metal, valley method, flashing, pipe boots, fasteners where material, and promised warranty system. The correct assembly depends on roof type, manufacturer instructions, code, and design.

How should plywood or deck replacement be priced?

Use an included quantity or allowance plus a defined unit, material, evidence, measurement, authorization, and reconciliation rule. “Decking extra if needed” is incomplete because it states neither the price nor who decides.

Who should warranty solar roof penetrations?

The contract should name the provider and distinguish installation workmanship, roof-material coverage, penetration/leak response, diagnosis, access, array removal, repair, interior damage, and reinstallation. Do not infer complete coverage from one warranty duration.

Can a 2026 solar and roof loan include a 30% federal homeowner credit assumption?

It should not assume a new §25D credit. Current IRS guidance says the residential credit is unavailable for property placed in service after December 31, 2025. Ask a tax professional about other provisions and personal facts.

Should I compare combined projects by solar cost per watt?

Not using the blended roof-plus-solar price. Compare the matched core PV price per DC watt, then evaluate roofing, electrical, financing, and other work separately. The household budget still includes every accepted scope.

What if the roof design changes the solar layout?

Require a revised layout, equipment schedule, production estimate, attachment detail, permit documents where affected, price reconciliation, and schedule. The owner should approve the final combined design before dependent work proceeds.

Is the lowest combined quote the best?

No. A lower total can exclude deck work, exact roof accessories, electrical work, permits, monitoring, service labor, or closeout. Normalize scope and unknowns first; then compare price, responsibility, evidence, and fit.

When should final payment be due?

Use a lawful project-specific schedule tied to stated evidence. Roof completion, solar mechanical completion, passed inspection, commissioning, utility authorization, and full closeout are distinct events. Do not assume one universal final-payment rule across states and contracts.

Sources, research method, and limits

This article was researched on August 10, 2026 using exact-keyword, combined-contract, roofing-estimate, solar-proposal, New England consumer-law, IRS, DOE, CFPB, manufacturer-document, and homeowner-forum searches. Representative search results tended to cover either solar quote fields or roofing quote fields; few reconciled duplicate contracts, separate prices, roof/PV interface obligations, acceptance evidence, financing, and current post-2025 federal tax treatment in one worksheet.

Forum language shaped questions about duplicate roof contracts, incomplete roof exhibits, flashing coordination, decking adders, leak responsibility, and future array removal. No anonymous post supports a legal rule, cost, product, company, or performance claim. Manufacturer links illustrate why exact assembly and attachment documents matter; they are not product recommendations.

No verified Teamsun roof inspection, proposal, combined price, decking rule, roof product, attachment detail, contractor arrangement, license, warranty, project schedule, finance term, closeout package, or completed-project record was available for this article. The blank fields are deliberate. The live service page supports requesting a solar-plus-roof discussion, not assuming those project-specific facts.

Compare the documents before choosing the delivery model

A combined project is ready for selection when its roof price, solar price, combined price, scope exhibits, legal parties, change rules, milestones, financing, warranties, and acceptance records tell one consistent story. One contract may win; coordinated contracts may win. The document trail—not the bundle label—decides which structure protects the homeowner better.

Bring your existing roof report, attic or deck information, electric bills, proposed designs, and every contract or finance document. Discuss Your Roof + Solar Project and ask Teamsun to complete the same normalizer before you choose.
