No. The City of Twin Falls does not publish a dedicated roofing permit application. Re-roofing is permitted under the general Residential Interior Remodel or Commercial Remodel building permit application and is fee-assessed using the standard valuation-based Building Permit Fee schedule, since the Master City-Wide Fee Schedule explicitly defines 'roofing' as part of declared project value.
