Tri-State code checkpoints · official references
Start With the Project’s Actual Jurisdiction
Energy and building-code requirements differ between New York City, the rest of New York State, New Jersey, and Connecticut. Confirm the code edition, amendments, existing-building rules, permit date, occupancy, and scope with the local authority and qualified design professional before setting insulation or roof-system assumptions.
New York State outside NYC
New York City has a separate code framework. Check the state code and any more restrictive local standards for the project municipality.
New Jersey
The state’s current code listing identifies the commercial energy subcode as ASHRAE 90.1-2022; confirm adoption and applicability for the permit and project.
NJ Department of Community Affairs · Current Construction Codes
Connecticut
The state lists the 2022 Connecticut State Building Code, based on 2021 International Codes, for applicable permit applications.
This guide does not calculate code compliance. A single R-value or “cool roof” rule should not be assumed to apply across all three states or every roof project.

Not Maximum Roofing pricing. The values above are third-party published estimates or a modeled scenario. They are not bids, verified paid costs, or Maximum Roofing project records. The snapshot does not provide a comparable general overlay rate. Ask each contractor to state tear-off or recovery, disposal, insulation, cover board, flashing, drainage, deck repairs, access, permits, and warranty scope.
Field documentation
Commercial Roof Condition: Evidence to Collect
A repeatable record helps owners, facility teams, contractors, and consultants discuss the same roof conditions. Arrange safe access and use inspection methods appropriate to the roof assembly.
| Observation | Record | Questions for follow-up |
|---|---|---|
| Membrane blistering, open seams, or delamination | Location, extent, close photographs with scale, membrane type if known, and whether the area changes after weather. | Is the condition isolated or widespread? What do the surrounding layers and seams show? |
| Cracking or surface wear on built-up / modified-bitumen roofing | Photo and roof-plan location; note whether reinforcement or underlying layers appear exposed. | Does the finding require a closer assessment or a core sample? Is the deck condition known? |
| Standing water or drainage concern | Drain and overflow locations, approximate ponding boundaries, photos, and time observed after rainfall. | Could blocked drains, low areas, insulation, slope, or deck conditions contribute? Check applicable warranty documents. |
| Suspected wet insulation or interior moisture | Interior leak locations, dates, weather, thermal images if taken, and any test method or report. | What method was used, what did it measure, and where should findings be confirmed by targeted investigation? |
| Flashing, curbs, penetrations, and roof edges | Photos of transitions, equipment, nearby seams, previous patches, and any recent rooftop work. | Are details compatible with the existing system and the proposed repair or restoration scope? |
Thermal images, moisture surveys, electronic leak detection, and core samples have different purposes and limits. A test result should be interpreted with its method, conditions, roof assembly, and inspection scope documented.
Decision framework
Compare the Scope Before Comparing the Total
Repair
Ask which defect is being addressed, what nearby materials were inspected, and whether recurring leaks suggest a wider issue. Record any temporary measure separately from permanent work.
Restoration or coating
Ask whether the existing roof is suitable, how moisture and damaged areas will be evaluated, what repairs and preparation are included, and which product and warranty conditions apply.
Replacement
Compare removal, disposal, substrate and insulation assumptions, drainage, flashing, edges, penetrations, access, occupied-space protection, and how concealed conditions are handled.
Operating and financial assumptions
Separate quoted project costs from estimates for future repairs, disruption, energy, financing, and tax. Identify who supplied each assumption and how uncertain it is.
Facility handover checklist
Build a Useful Roof Record
- Mark the roof areas on a plan and assign consistent location names.
- Record roof type, approximate age, known repairs, leak dates, and available warranty documents.
- Store dated photographs with the observer, location, weather context, and any test method.
- List drains, overflows, rooftop equipment, access points, and sensitive areas below.
- For each proposal, note included areas, preparation, materials, exclusions, schedule, cleanup, and approval steps for extra work.
- After work, retain closeout photos, invoices, product information, warranty documents, and maintenance requirements.

Cost references and calculator notes
40 Price and Planning FAQs
Prices in these answers are published third-party New York estimates from the source links; they are not Maximum Roofing quotes. Each range retains its source assumptions. The figures do not establish pricing in New Jersey or Connecticut.
Does the calculator provide a contractor quote?
No. It models costs from values entered by the user and does not produce a site-specific quote or determine roof suitability.
Does the calculator determine code compliance?
No. Code requirements vary by jurisdiction, project scope, permit date, and building conditions. Check the applicable authority and qualified design professional.
Are insurance or energy savings guaranteed?
No. Enter savings only when supported by building-specific estimates or written information from the relevant professional, utility, insurer, or broker.

What is the modeled PVC price with R-30 insulation?
The model lists $17.25–$18.50 per sq. ft. for PVC with R-30 insulation, with tear-off/disposal included as described by the source. This is not a project-specific specification or bid. Roof Observations source.
What PVC range is listed in the Queens guide?
FlatMasters NY lists $12–$18 per sq. ft. for PVC and states that roof removal is excluded; the guide lists tear-off separately at $2–$4 per sq. ft. FlatMasters NY source.
Does the modeled New York table provide a standing-seam price without added insulation?
No. Its table does not show a comparable no-added-insulation option. It lists $15.30–$25.50 per sq. ft. for standing seam in its R-30 scenario. Roof Observations source.
What standing-seam range does the NYC / Long Island guide publish?
Elite Roofing NY lists $13–$25 per sq. ft. for standing seam. Confirm panel material, roof pitch, insulation, tear-off, flashing, and other scope in the actual proposal. Elite Roofing NY source.
Does the Queens source list standing-seam metal pricing?
The price snapshot does not include a standing-seam rate from the Queens guide. Use the specific published ranges elsewhere in the snapshot only with their stated source and scope, or compare written bids.
What published price is listed for silicone roof coating restoration in NYC?
NYC Renovators publishes an estimate of $3.50–$7 per sq. ft. for silicone coating restoration. It is not a replacement-roof price; preparation, repairs, roof condition, coating requirements, and warranty scope affect suitability and cost. NYC Renovators source.
Is silicone coating the same as an overlay roof replacement?
No. The cited $3.50–$7 per sq. ft. is a published silicone-restoration estimate. The New York price snapshot does not establish a comparable general overlay price, and a coating should not be assumed suitable without project-specific inspection and product requirements. NYC Renovators source.
What overlay price per square foot should I use from this snapshot?
The snapshot does not provide a verified, comparable New York overlay rate. Ask each bidder to state whether the scope is a recover/overlay or tear-off and replacement, what existing layers remain, and any insulation, deck, and warranty conditions.
How much extra does tear-off add in the Queens guide?
FlatMasters NY lists tear-off at $2–$4 per sq. ft., separate from its system ranges. Its listed installation rates exclude removal, so do not add this twice if another quote already includes tear-off. FlatMasters NY source.
How much extra does tear-off add in the NYC / Long Island guide?
Elite Roofing NY lists tear-off/disposal separately at $1.50–$3 per sq. ft. This is one publisher’s estimate; disposal, access, layers, and actual scope may differ. Elite Roofing NY source.
How much extra does tear-off add in the NYC flat-roof guide?
MGR Restoration lists tear-off at $2–$5 per sq. ft. separately from its system ranges. Verify the number of existing layers, disposal, access, and included work before using it in a comparison. MGR Restoration source.
Is tear-off already included in the Roof Observations modeled system figures?
The published New York model says it includes $1.50 per sq. ft. for tear-off and disposal in its 25,000-sq.-ft. scenario. Do not add another tear-off allowance to those modeled figures unless changing the scenario deliberately. Roof Observations source.
What insulation upgrade add-on does the NYC flat-roof guide list?
MGR Restoration lists an insulation-upgrade range of $2–$8 per sq. ft. Its application depends on the project scope; it is not an independent R-value specification or code recommendation. MGR Restoration source.
Why does the New York snapshot show different prices for the same roof system?
The publishers use different assumptions and scopes. The snapshot identifies examples such as tear-off inclusion, insulation, system type, and ply count. Compare the proposal details rather than averaging the separate published figures.
Can I call these Maximum Roofing prices?
No. These figures are third-party published estimates and a third-party modeled scenario. They are not Maximum Roofing bids, verified paid costs, or project records. Request a project-specific written estimate for company pricing.
Do these New York figures apply to New Jersey and Connecticut?
They are New York-published references only. The snapshot does not establish equivalent market prices for New Jersey or Connecticut; local labor, code, access, material, and scope should be checked for each project.
Are the published figures guaranteed or a current bid?
No. They are planning references from their respective publishers, not guaranteed prices. Confirm current material, labor, access, tear-off, insulation, repair, and warranty scope with bidders.
How should I compare two commercial roof estimates?
Compare the same roof area and system, then list tear-off/recovery, disposal, insulation, cover board, flashing, drainage, deck repairs, access, permits, schedule, and warranty requirements. Record exclusions and allowances beside each total.
How do I use the published prices in the calculator?
Use the calculator to enter the actual written proposal rates and project assumptions. If you test a third-party published range, label it as a scenario and keep its source, included tear-off, insulation assumptions, and date with your notes.
What BUR range does the Queens guide publish?
FlatMasters NY lists $11–$16 per sq. ft. for built-up roofing and states roof removal is excluded; the guide separately lists tear-off at $2–$4 per sq. ft. FlatMasters NY source.
How can I convert a published per-square-foot rate into a rough roof total?
Multiply the stated rate by the measured roof area for a rough arithmetic scenario only, then account separately for scope items the source excludes. For example, do not treat a third-party range as a bid or as a total project estimate without confirming area, tear-off, insulation, repairs, access, disposal, and other proposal terms.
