Town of Cary - Inspections & Permits
No, Cary, NC does not require a permit for like-for-like roof replacement (Town of Cary - Inspections & Permits). A reroof of a single-family house in Cary costing $40,000 or less generally needs no building permit. The state exemption, G.S. 160D-1110(c), covers work "costing forty thousand dollars ($40,000) or less and performed in accordance with the current edition of the North Carolina State Building Code in any single-family residence" unless it involves "The addition, repair, or replacement of load-bearing structures", "The use of materials not permitted by the North Carolina State Building Code" or "The addition of roofing, excluding replacement." The state's R908.3 amendment adds that "Replacement of up to 15% of the total roof deck shall not be considered structural work." The Town's FAQ lists "roof coverings with the same materials" among work for which a residential permit is NOT required. Get a permit when the job exceeds $40,000, involves structural or load-bearing work, replaces more than 15% of the deck, adds new roof area, or is on a duplex, multi-family or commercial building; the Town charges double permit fees for work started without a required permit. Removing and reinstalling rooftop solar needs its own permit. Permits are applied for online; the permit office is on the first floor of Cary Town Hall, 316 N. Academy Street, open 8:30 a.m. to 5 p.m. weekdays; questions go to 311 or (919) 469-4000.

Registration details
- state_level: North Carolina licenses general contractors at the state level by the cost of the job. G.S. 87-1(a) treats as a general contractor anyone who undertakes to bid upon or to construct "any building, highway, public utilities, grading or any improvement or structure where the cost of the undertaking is forty thousand dollars ($40,000) or more". The Town's Residential Guide puts it this way: "In North Carolina, a contractor's license is only required for jobs that cost $40,000 or more." A roofing job below that cost is not reached by the general contractor licence; one at or above it is. G.S. 87-1(b)(2) exempts an owner who builds or alters a building on the owner's own land that is "intended solely for occupancy by that person and his family", with a presumption against the exemption if the owner does not occupy it for at least 12 months; the Town's forms page carries the state Owner Exemption Affidavit used to claim it. This record does not decide which side of the cost line a particular job falls on.
- city_level: The Town of Cary issues no contractor licence or registration of its own. Its plan reviewers verify contractors' state licences ("During that time, your contractors' licenses are verified"), permit applicants list each contractor's name, address and state license number, and licensed general contractors on work costing $40,000 or more file the Town's Workers' Compensation Insurance and License Tax Verification form.
Permit process note
A reroof of a single-family house in Cary costing $40,000 or less generally needs no building permit. The state exemption, G.S. 160D-1110(c), covers work "costing forty thousand dollars ($40,000) or less and performed in accordance with the current edition of the North Carolina State Building Code in any single-family residence" unless it involves "The addition, repair, or replacement of load-bearing structures", "The use of materials not permitted by the North Carolina State Building Code" or "The addition of roofing, excluding replacement."

Adopted code
The 2018 North Carolina Residential Code is the edition in force; the 2024 edition has been adopted but has no effective date. The Town does not write a building code of its own. Its NC Building Codes page states: "Per section 8-52 of the Town of Cary Code of Ordinances, the Town has adopted the North Carolina State Building Code. The only building regulations enforced by the Town are those found in the state-adopted Building Code in force at the time of permit for construction." The same page lists the "2018 North Carolina Residential Code" as in effect from January 1, 2019, and says "2024 Codes may be used as an alternative method" where "The plan set shall clearly identify that it is being submitted under the 2024 NC Building Codes." North Carolina's roofing amendments include R905.2.8.5, which reads "Drip Edge. Deleted. Not required unless required by the roof covering manufacturer installation instructions."
Repair permit threshold
North Carolina law exempts most single-family reroofs from a building permit. G.S. 160D-1110(c) reads: "No permit issued under Article 9 of Chapter 143 of the General Statutes is required for any construction, installation, repair, replacement, or alteration costing forty thousand dollars ($40,000) or less and performed in accordance with the current edition of the North Carolina State Building Code in any single-family residence, farm building, or commercial building unless the work involves any of the following: (1) The addition, repair, or replacement of load-bearing structures." Among the other listed exceptions are "(4) The use of materials not permitted by the North Carolina State Building Code" and "(5) The addition of roofing, excluding replacement." G.S. 143-138(b5) says the same: "No permit shall be required under the Code or any local variance thereof approved under subsection (e)" for such work. The North Carolina Residential Code's own reroof amendment draws the structural line: "R908.3 Roof replacement. Roof replacement shall include the removal of existing layers of roof coverings down to the roof deck and replacement of up to 15% of the total existing roof deck. Replacement of up to 15% of the total roof deck shall not be considered structural work." So a reroof of a single-family house costing $40,000 or less, with deck replacement of no more than 15% of the roof and no load-bearing work, needs no permit. A job over $40,000, one that repairs or replaces rafters, trusses or other load-bearing members, one that adds roofing rather than replacing it, and work on a duplex or other multi-family building all fall outside the exemption. The Town of Cary agrees: its permit FAQ, under "When is a residential permit NOT required?", lists "Replacement or repair of non-structural cosmetic building elements" including "roof coverings with the same materials". The FAQ names only same-material replacement; it does not address a change of roofing material, which the statute reaches only where the new material is permitted by the State Building Code. The Town's residential fee schedule for one- and two-family dwellings, published in its FY2027 budget document, has no reroofing line (its "Re-Roof" fee appears only in the commercial table), and the schedule states "Double permit fees shall be charged for work started without a permit". Solar owners should note the FAQ lists as permit work "Solar or photovoltaic equipment includes reinstalling equipment when a roof is replaced."
Roof layer limit / recover
Cary enforces the North Carolina Residential Code without local building amendments of its own (its NC Building Codes page says "The only building regulations enforced by the Town are those found in the state-adopted Building Code in force at the time of permit for construction"). North Carolina amends the reroofing section of the code: "R908.3 Roof replacement. Roof replacement shall include the removal of existing layers of roof coverings down to the roof deck and replacement of up to 15% of the total existing roof deck. Replacement of up to 15% of the total roof deck shall not be considered structural work." Whether a new covering may go over an existing one, and over how many, is set by the recover provisions of the 2018 North Carolina Residential Code (R908.3.1 and R908.3.1.1), which are not restated here; check them, or ask the Town, before quoting a recover.
Deck & sheathing requirements
The Town of Cary publishes no roof sheathing rule of its own; it states that the only building regulations it enforces are those of the state-adopted Building Code. Under the 2018 North Carolina Residential Code as amended by the state, a roof replacement includes "replacement of up to 15% of the total existing roof deck", and "Replacement of up to 15% of the total roof deck shall not be considered structural work." Replacing more of the deck than that, or any load-bearing framing, is outside the state's reroof permit exemption and needs a building permit. Sheathing materials, thickness and fastening follow the state residential code's roof sheathing provisions (Chapter 8), which are not restated here.
Sales & use tax
Cary lies mainly in Wake County, with parts in Chatham and Durham counties (the Town's budget describes it as "Primarily within Wake and Chatham counties, with a small presence in Durham County"), so the rate depends on the address. The North Carolina Department of Revenue lists these combined rates (the 4.75% state rate plus local and transit rates): Wake County 7.25% and Durham County 7.5%, each including the 0.50% transit tax, and Chatham County 7%. How the tax applies depends on the kind of roofing job, and the two treatments are different. NCDOR's taxability chart for services to real property lists "Complete replacement of roofing systems" and "Installation of complete roofing systems" as capital improvements: under a real property contract the roofer is the consumer of the materials and pays sales or use tax on them, and does not charge sales tax to the homeowner on the contract. The same chart lists "Repair, maintain, or partially replace all types of roofing systems" and "Repair, maintain, install, or replace roofing materials (asphalt, shingle, slate, tile, built-up, metal, single ply)" as "Taxable" repair, maintenance and installation services, charged to the customer at the combined rate for the job's county.
