What happens if you skip the permit (and you needed one)
- Stop-work order and $250–$500 fine from Farragut Building Department; if city discovers unpermitted roof after installation, you'll owe double permit fees ($300–$700) plus re-inspection costs.
- Insurance claim denial: if storm damage or other loss occurs post-replacement, insurers investigate permit history and may deny payout if the roof was installed without permit (common rejection in Knox County area).
- Home sale blocked or appraised lower: Tennessee Transfer Disclosure Statement (TDS) requires disclosure of unpermitted work; buyers' lenders will deny financing if roof isn't permitted and inspected, costing you the sale or forcing a costly tear-off and redo.
- Lien attachment: contractor hired without a permit can file a mechanic's lien in Knox County for non-payment, and you lose your right to dispute the bill if no permit was pulled (TN mechanic's lien law favors documented work).
Farragut roof replacement permits — the key details
Farragut's Building Department enforces the International Residential Code (IRC) R907 (reroofing) and R905 (roof-covering requirements), which dictate when a roof permit is mandatory and what the installation must meet. The core trigger is simple: any tear-off of existing roofing material down to the deck requires a permit. Additionally, IRC R907.4 states that if a roof has three or more layers of existing shingles or felt, the old roof MUST be torn off before a new one is installed—no overlays allowed. This is a hard-stop rule in Farragut; the city inspector will cite this code section in any rejection. A repair that touches less than 25% of the roof area and does not involve removal to the deck (e.g., patching a valley or replacing a few cracked shingles) may be exempt from permitting, but the moment you begin stripping shingles or tearing into the deck, you've crossed the permit threshold. Farragut's Building Department requires all roof applications to include the existing roof condition (number of layers, material type) and a proposed material specification before the permit is issued. If the applicant or contractor cannot confirm the number of layers, the city may require a field inspection or decay-condition affidavit before approval.
