Accounting Policies [Abstract] |
Consolidation, Policy [Policy Text Block] | Principles of Consolidation—RGC Resources, Inc. is an energy services company primarily engaged in the sale and distribution of natural gas. The consolidated financial statements include the accounts of Resources and its wholly owned subsidiaries: Roanoke Gas and Midstream. Roanoke Gas is a natural gas utility, which distributes and sells natural gas to approximately 62,500 residential, commercial and industrial customers within its service areas in Roanoke, Virginia and the surrounding localities. The Company’s business is seasonal in nature as a majority of natural gas sales are for space heating during the winter season. Roanoke Gas is regulated by the SCC. Midstream is a wholly owned subsidiary created primarily to invest in the LLC. The Company follows accounting and reporting standards established by the FASB and the SEC, including certain provisions allowed under the smaller reporting company exceptions.
Public Utilities, Policy [Policy Text Block] | Rate Regulated Basis of Accounting—The Company’s regulated operations follow the accounting and reporting requirements of ASC 980, Regulated Operations. The economic effects of regulation can result in a regulated company deferring costs that have been or are expected to be recovered from customers in a period different from the period in which the costs would be charged to expense by an unregulated enterprise. When this situation occurs, costs are deferred as assets in the consolidated balance sheet (regulatory assets) and recorded as expenses when such amounts are reflected in rates. Additionally, regulators can impose liabilities upon a regulated company for amounts previously collected from customers and for current collection in rates of costs that are expected to be incurred in the future (regulatory liabilities). In the event the provisions of ASC 980 no longer apply to any or all regulatory assets or liabilities, the Company would write off such amounts and include them in the consolidated statements of income and comprehensive income in the period which ASC 980 no longer applied. Regulatory assets and liabilities included in the Company’s consolidated balance sheets as of September 30, 2025 and 2024 are as follows:

Amortization of $101,141 and $116,085 of regulatory assets for the years ended September 30, 2025 and 2024, respectively, is included in operations and maintenance expense on the consolidated statements of income. Amortization of $131,673 and $211,863 of regulatory assets for the years ended September 30, 2025 and 2024, respectively, is included in other income, net on the consolidated statements of income. Amortization of $114,187 of regulatory assets for both years ended September 30, 2025 and 2024 is included in interest expense on the consolidated statements of income. As of September 30, 2025, the Company had regulatory assets in the amount of $5,897,920 on which the Company did not earn a return during the recovery period.
Regulatory Depreciation and Amortization, Policy [Policy Text Block] | Utility Property and Depreciation—Utility property is stated at original cost and includes direct labor and materials, contractor costs, and all allocable overhead charges. The Company applies the group method of accounting, where the costs of like assets are aggregated and depreciated by applying a rate based on the average expected useful life of the assets. In accordance with Company policy, expenditures for depreciable assets with a life greater than one year are capitalized, along with any upgrades or improvements to existing assets, when such upgrades or improvements significantly improve or extend the original expected useful life. Expenditures for maintenance, repairs, and minor renewals and betterments are expensed as incurred. The original cost of depreciable property retired is removed from utility property and charged to accumulated depreciation. The cost of asset removals, less salvage, is charged to “regulatory cost of retirement obligations” or “asset retirement obligations” as explained under Asset Retirement Obligations below. Utility property is composed of the following major classes of assets:
|  | September 30 |
|  | 2025 |  |  | 2024 |
Distribution and transmission |  | $ | 330,895,437 |  |  | $ | 312,999,348 |
LNG storage |  |  | 15,863,849 |  |  |  | 15,437,447 |
General and miscellaneous |  |  | 20,084,067 |  |  |  | 17,427,213 |
Total utility property in service |  | $ | 366,843,353 |  |  | $ | 345,864,008 |
Provisions for depreciation are computed principally at composite straight-line rates over a range of periods. Rates are determined by depreciation studies, which are required to be performed at least every 5 years on the regulated utility assets of Roanoke Gas. The most recent depreciation study was completed and approved by the SCC staff in fiscal 2024. The composite weighted-average depreciation rate was 3.26% for both years ended September 30, 2025 and 2024. The composite rates are composed of two components, one based on average service life and one based on cost of retirement. As a result, the Company accrues the estimated cost of retirement of long-lived assets through depreciation expense. These retirement costs are not a legal obligation but rather the result of cost-based regulation and are accounted for under the provisions of ASC 980. Such amounts are classified as a regulatory liability. The Company reviews long-lived assets and certain identifiable intangibles for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. These reviews have not identified any impairments which would have a material effect on the results of operations or financial condition. From time to time, the Company recognizes AFUDC related to large infrastructure investments. This treatment allows capitalizing both the equity and debt financing costs during the construction phases. The Company did not capitalize any financing costs related to projects for the years ended September 30, 2025 and 2024.
Asset Retirement Obligation [Policy Text Block] | Asset Retirement Obligations—ASC 410, Asset Retirement and Environmental Obligations, requires entities to record the fair value of a liability for an ARO when there exists a legal obligation for the retirement of the asset. When the liability is initially recorded, the entity capitalizes the cost, thereby increasing the carrying amount of the underlying asset. In subsequent periods, the liability is accreted, and the capitalized cost is depreciated over the useful life of the underlying asset. The Company has recorded AROs for its future regulatory obligations related to purging and capping its distribution mains and services upon retirement, although the timing of such retirements is uncertain. The following is a summary of the AROs:
|  | Years Ended September 30 |
|  | 2025 |  |  | 2024 |
Beginning balance |  | $ | 11,142,095 |  |  | $ | 10,792,831 |
Liabilities incurred |  |  | 72,502 |  |  |  | 86,483 |
Liabilities settled |  |  | (138,391 | ) |  |  | (168,913 | )
Accretion |  |  | 564,229 |  |  |  | 582,383 |
Revisions to estimates and other |  |  | — |  |  |  | (150,689 | )
Ending balance |  | $ | 11,640,435 |  |  | $ | 11,142,095 |
Cash and Cash Equivalents, Policy [Policy Text Block] | Cash, Cash Equivalents and Short-Term Investments—From time to time, the Company will have balances on deposit at banks in excess of the amount insured by the FDIC. The Company has not experienced any losses on these accounts and does not consider these amounts to be at risk. For purposes of the consolidated statements of cash flows, the Company considers all highly liquid debt instruments purchased with an original maturity of three months or less to be cash equivalents.
Accounts Receivable [Policy Text Block] | Customer Receivables and Allowance for Credit Losses—Accounts receivable include amounts billed to customers for natural gas sales and related services and gas sales occurring subsequent to normal billing cycles but before the end of the period. The Company provides an estimate for losses on these receivables by utilizing historical information, current account balances, account aging and current economic conditions. Customer accounts are charged off annually when deemed uncollectible or when turned over to a collection agency for action. A reconciliation of changes in the allowance for credit losses is as follows:
|  | Years Ended September 30 |
|  | 2025 |  |  | 2024 |
Beginning balance |  | $ | 153,347 |  |  | $ | 155,164 |
Provision for credit losses |  |  | 278,606 |  |  |  | 110,676 |
Recoveries of accounts written off |  |  | 140,727 |  |  |  | 173,660 |
Accounts written off |  |  | (429,769 | ) |  |  | (286,153 | )
Ending balance |  | $ | 142,911 |  |  | $ | 153,347 |
Lessor, Leases [Policy Text Block] | Lease Accounting—The Company leases certain assets including office space and land classified as operating leases. The Company determines if an arrangement is a lease at inception of the agreement based on the terms and conditions in the contract. The operating lease ROU assets and operating lease liabilities are recognized as the present value of the future minimum lease payments over the lease term at commencement date. As most of the leases do not provide an implicit rate, the Company uses an estimate of its secured incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The incremental borrowing rate is determined by management aided by inquiries of a third party. The operating lease ROU asset also is adjusted for any lease payments made and excludes lease incentives and initial direct costs incurred. The Company’s lease terms may include options to extend or terminate the lease at certain dates, typically at the Company’s own discretion. The Company regularly evaluates the renewal options and when they are reasonably certain of exercise, the Company includes the renewal period in its lease term. Lease expense for minimum lease payments is recognized on a straight-line basis over the term of the agreement. The Company made an accounting policy election that payments under agreements with an initial term of 12 months or less will not be included on the consolidated balance sheet but will be recognized in the consolidated statements of operations on a straight-line basis over the term of the agreement.
Inventory, Policy [Policy Text Block] | Inventories—Natural gas in storage and materials and supplies inventories are recorded at average cost. Natural gas storage injections are priced at the purchase cost at the time of injection and storage withdrawals are priced at the weighted average cost of gas in storage. Materials and supplies are removed from inventory at average cost.
Revenue [Policy Text Block] | Unbilled Revenues—The Company bills its natural gas customers on a monthly cycle; however, the billing cycle for most firm customers does not coincide with the accounting periods used for financial reporting. As the Company recognizes revenue when gas is delivered, an accrual is made to estimate revenues for natural gas delivered to customers but not billed during the accounting period. The amounts of unbilled revenue receivable included in accounts receivable on the consolidated balance sheets at September 30, 2025 and 2024 were $1,373,512 and $1,294,798, respectively.
Income Tax, Policy [Policy Text Block] | Income Taxes—Income taxes are accounted for using the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the years in which those temporary differences are expected to be recovered or settled. A valuation allowance against deferred tax assets is provided if it is more likely than not the deferred tax asset will not be realized. The Company and its subsidiaries file consolidated state and federal income tax returns.
Debt, Policy [Policy Text Block] | Debt Expenses—Debt issuance expenses are deferred and amortized over the lives of the debt instruments. The unamortized balances are offset against the carrying value of long-term debt.
Over/Under Recovery of Natural Gas Costs [Policy Text Block] | Over/Under-Recovery of Natural Gas Costs—From time to time, the Company enters into forward purchases of natural gas at fixed prices through its asset manager. As management believes it is probable these purchases will physically settle, the Company has applied the normal purchase and normal sale exception to derivative accounting. Pursuant to the provisions of the Company’s PGA clause, the SCC provides the Company with a method of passing along to its customers increases or decreases in natural gas costs incurred by its regulated operations, including gains and losses on natural gas derivative hedging instruments, if utilized. On at least a quarterly basis, the Company files a PGA rate adjustment request with the SCC to increase or decrease the gas cost component of its rates, based on projected price and activity. Once administrative approval is received, the Company adjusts the gas cost component of its rates to reflect the approved amount. As actual costs and usage will differ from the projections used in establishing the PGA rate, the Company may either over-recover or under-recover its actual gas costs during the period. Any difference between actual costs incurred and costs recovered through the application of the PGA is recorded as a regulatory asset or liability. At the end of the deferral period, the balance of the net deferred charge or credit is amortized over an ensuing 12-month period as amounts are reflected in customer bills.
Fair Value of Financial Instruments, Policy [Policy Text Block] | Fair Value—Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between willing market participants at the measurement date. The Company determines fair value based on the following fair value hierarchy which prioritizes each input to the valuation methods into one of the following three broad levels:
| • | Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
| • | Level 2 – Inputs other than quoted prices in Level 1 that are either for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, or inputs that are derived principally from or corroborated by observable market data by correlation or other means.
| • | Level 3 – Unobservable inputs for the asset or liability where there is little, if any, market activity which require the Company to develop its own assumptions.
The fair value hierarchy gives the highest priority to unadjusted quoted prices in active markets (Level 1) and the lowest priority to unobservable inputs (Level 3). All fair value disclosures are categorized within one of the three categories in the hierarchy based on the lowest level that is significant to the valuation. See fair value disclosures below and in Notes 8 and 12.
Use of Estimates, Policy [Policy Text Block] | Use of Estimates—The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Excise and Sales Taxes [Policy Text Block] | Excise and Sales Taxes—Certain excise and sales taxes imposed by the state and local governments in the Company’s service territory are collected by the Company from its customers. These taxes are passed through to the state and local governments and included within accounts payable on the Company's consolidated balance sheets.
Earnings Per Share, Policy [Policy Text Block] | Earnings Per Share—Basic EPS and diluted EPS are calculated by dividing net income by the weighted-average common shares outstanding during the period and the weighted-average common shares outstanding during the period plus potential dilutive common shares, respectively. Potential dilutive common shares are calculated in accordance with the treasury stock method, which assumes that proceeds from the exercise of all options are used to repurchase common stock at market value. The amount of shares remaining after the proceeds are exhausted represents the potentially dilutive effect of the securities. The computation of diluted EPS for the years ended September 30, 2025 and 2024 excludes potentially dilutive shares of 1,926 and 2,542, respectively, because to include them would be antidilutive for the period. However, these shares could potentially dilute EPS in the future. A reconciliation of basic and diluted EPS is presented below:
|  | Years Ended September 30 |
|  | 2025 |  |  | 2024 |
Net income |  | $ | 13,279,970 |  |  | $ | 11,760,896 |
Weighted-average common shares |  |  | 10,304,109 |  |  |  | 10,152,909 |
Effect of dilutive securities: |  |  |  |  |  |  |  |
Options to purchase common stock |  |  | 4,577 |  |  |  | 3,571 |
Diluted average common shares |  |  | 10,308,686 |  |  |  | 10,156,480 |
Earnings per share of common stock: |  |  |  |  |  |  |  |
Basic |  | $ | 1.29 |  |  | $ | 1.16 |
Diluted |  | $ | 1.29 |  |  | $ | 1.16 |
Concentration Risk, Credit Risk, Policy [Policy Text Block] | Business and Credit Concentrations—The primary business of the Company is the distribution of natural gas to residential, commercial and industrial customers in its service territories. No sales to individual customers accounted for more than 5% of total revenue in any period. No individual customer amounted to more than 5% of total accounts receivable at September 30, 2025 and 2024. Roanoke Gas currently holds the only franchises and/or CPCNs to distribute natural gas in its service area. These franchises generally extend for multi-year periods, are renewable by the municipalities and are intended for perpetual duration, including exclusive franchises in the cities of Roanoke, Salem and the Town of Vinton. All franchises are set to expire December 31, 2035. Roanoke Gas is currently served by three primary pipelines that provide the natural gas supplied to the Company’s customers. Depending upon weather conditions and the level of customer demand, failure of one or all of these transmission pipelines could have a major adverse impact on the Company.
Derivatives, Policy [Policy Text Block] | Derivative and Hedging Activities—ASC 815, Derivatives and Hedging, requires the recognition of all derivative instruments as assets or liabilities in the Company’s consolidated balance sheet and measurement of those instruments at fair value. The Company’s hedging and derivatives policy allows management to enter into derivatives for the purpose of managing the commodity and financial market risks of its business operations. The Company’s hedging and derivatives policy specifically prohibits the use of derivatives for speculative purposes. The key market risks that the Company may hedge against include the price of natural gas and the cost of borrowed funds. From time to time, the Company has entered into collars, swaps and caps for the purpose of hedging the price of natural gas in order to provide price stability during the winter months. The fair value of these instruments is recorded in the consolidated balance sheets with the offsetting entry to either under- or over-recovery of gas costs. Net income and other comprehensive income are not affected by the change in market value as any cost incurred or benefit received from these instruments is recoverable or refunded through the PGA as the SCC allows for full recovery of prudent costs associated with natural gas purchases. At September 30, 2025 and 2024, the Company had no outstanding derivative instruments for the purchase of natural gas. The Company has six interest rate swaps associated with certain of its variable rate debt. Roanoke Gas has two variable rate term notes in the amounts of $15 million and $10 million, with corresponding swap agreements to convert the variable interest rates into fixed rates of 2.00% and 2.49%, respectively. Midstream has four swap agreements in the amounts of $14 million, $4 million, $20.6 million, and $15 million, corresponding to the $53.6 million variable rate term note. The swap agreements convert the note into a fixed rate instrument with effective interest rates of 3.24%, 2.443%, 5.061%, and 5.061%, respectively. The swaps qualify as cash flow hedges with changes in fair value reported in other comprehensive income. No portion of the swaps were deemed ineffective during the periods presented. See Notes 7 and 8 for additional information on the swaps and fair value.

New Accounting Pronouncements, Policy [Policy Text Block] | Recently Adopted Accounting Standards In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures, which enhances and expands the current annual and interim requirements on segment information disclosures. The new guidance requires disclosure of significant segment expenses that are regularly provided to the chief operating decision maker (CODM) and included within each reported measure of segment profit or loss, an amount and description of the composition of other segment items to reconcile to segment profit or loss, and the title and position of the entity's CODM. The provisions within the guidance are to be applied retrospectively for all comparative periods and are effective for the Company for the fiscal year that began October 1, 2024 and interim periods within fiscal year beginning October 1, 2025. The Company adopted ASU 2023-07 effective for the year ended September 30, 2025, with retrospective application of the additional segment information for the year ended September 30, 2024. Additional information regarding the Company's reportable segments is included in Note 3 to the consolidated financial statements, with no impact on results of operations, cash flows, or financial condition of the Company. Recently Issued Accounting Standards In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The new guidance requires that on an annual basis public business entities disclose specific categories in the rate reconciliation table and provide additional information for reconciling items that meet a quantitative threshold (items equal to or greater than 5 percent of the amount computed by multiplying pretax income or loss by the applicable statutory rate). The required disclosures will provide more granularity regarding the payment of income taxes to federal, state and foreign entities. The Company does not expect certain requirements of this ASU to have a significant impact to its current disclosures as all of its operations are domestic and reside in two states. Changes to the rate reconciliation table will result in additional disclosure. The new guidance is effective for the Company for annual periods beginning October 1, 2025. In November 2024, the SEC issued ASU 2024-03, Income Statement - Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures. The new guidance requires public business entities to disclose certain additional detail about expenses including, among other items, purchases of inventory, employee compensation, depreciation and intangible asset amortization included within each income statement expense line items within continuing operations. The guidance also requires disclosure of the total amount of selling expenses and the Company’s definition of selling expenses. Such disclosures must be made on an annual and interim basis and integrated with existing disclosure requirements in a tabular format in the footnotes to the financial statements. Further, in January 2025, the FASB issued ASU 2025-01, Income Statement - Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures: Clarifying the Effective Date, which clarified the effective date of ASU 2024-03. The new guidance is effective for the Company for annual periods beginning October 1, 2027 and interim periods within fiscal year beginning October 1, 2028. The Company is currently assessing the impacts of the new guidance on its financial statement disclosures. Other accounting standards that have been issued or proposed by the FASB or other standard–setting bodies are not currently applicable to the Company or are not expected to have a significant impact on the Company’s financial position, results of operations and cash flows.
