Do you need a permit for Roof Replacement in Tompkins County?
In New York, a Roof Replacement requires a building permit.
Replacing a roof requires a building permit in virtually every jurisdiction (IRC R907). Minor repairs under roughly one square (about 100 sq ft), like patching a leak or swapping a few shingles, are usually exempt. A roof with three or more existing layers must be torn off to the deck before re-roofing (IRC R907.4). Plans are reviewed under the Statewide (exc. NYC) code (IRC 2024); apply through Ithaca Building Department before work begins.

With a growing population of around 104,537 residents, Tompkins County maintains a relatively streamlined permitting process compared to major urban hubs. Processing typically takes 1 to 3 weeks.
Code Compliance & Inspections
Because of severe winter weather in New York, any exterior structures or footings must be set below the local frost line to prevent shifting, as mandated by the NYS Uniform Fire Prevention and Building Code.
Technical Requirement: It is mandatory to install Ice and Water Shields on the roof eaves to prevent leaks from ice dams during New York winters.
Concurrent Permits & HOAs
For Tompkins County residents, we highly recommend reviewing your neighborhood HOA covenants before paying any municipal fees. Often, homeowners associations maintain stricter rules regarding materials and dimensions for your Roof Replacement than the county itself.
