The Short Answer
A full roof replacement or any tear-off-and-replace requires a permit from the City of Paris Building Department. Like-for-like patching under 25% of roof area may be exempt, but once you're tearing off the existing roof, you need a permit.
Paris does not have a separate municipal building code; it adopts the Texas Building Code, which incorporates the 2015 IBC and IRC. This means you're subject to IRC R907 (reroofing) nationwide rules, but Paris-specific enforcement hinges on the Building Department's current staffing and review speed — which can vary significantly. Unlike larger Texas cities with dedicated plan-review teams, Paris often handles permits on a faster, over-the-counter basis for straightforward reroof jobs. The critical Paris-local factor: because the city sits in both 3A and 4A climate zones (depending on exact location), flashing and ice-and-water-shield requirements shift — a roof in north Paris (4A) needs more stringent eave protection than one in south Paris (3A). Confirm your exact address climate zone with the Building Department before submitting; this determines whether you need water-shield to 24 inches or 12 inches from the eave. Permits typically cost $150–$300 depending on roof square footage (often calculated at $1.50–$2.50 per square). Most like-for-like reroof jobs are over-the-counter approvals; full applications with underlayment specs and fastening details are reviewed within 3–7 business days.

What happens if you skip the permit (and you needed one)

Paris roof replacement permits — the key details

IRC R907.4 is the core rule: if there are already three or more layers of roofing on the deck, you MUST tear off all layers down to the deck before applying new material. This is a fire-safety rule (too much weight, fire propagation risk) and is enforced nationwide. Paris Building Department inspectors will require photographic proof of how many layers exist before you start; if you miss this and a third-layer is discovered during framing inspection, the city will issue a stop-work order and require complete removal. If you're doing a tear-off-and-replace (whether the roof has 1, 2, or 3+ layers), that is always a permitted scope. Like-for-like patching of fewer than 10 squares (a square = 100 sq ft) on a sound deck, without tear-off, falls into the exempt repair category — but once you exceed 25% of total roof area or you're peeling off the existing membrane, you've crossed into replacement and need a permit. The permit application requires you to specify existing roof material (asphalt shingles, metal, tar-and-gravel, etc.), new material, square footage, and whether you're doing a full tear-off or overlay (if 2 or fewer existing layers).

Underlayment and flashing specs are the second major checkpoint. IRC R905 mandates synthetic or asphalt-saturated felt underlayment under asphalt shingles; metal roofs require a vapor-permeable membrane. Paris inspectors will ask for the product name and fastening pattern (nail size, spacing, whether ring-shank or smooth-shank). For ice-and-water-shield, Texas Building Code 2015 (which Paris adopts) requires it in areas prone to ice dams; because Paris straddles climate zones 3A and 4A, the requirement varies. If your property is in the panhandle or northern Paris area (4A), you'll need ice-and-water-shield extending at least 24 inches from the eave, or one course up from where the roof meets the wall, whichever is greater. In central Paris (3A), 12 inches is typically sufficient. Flashing at valleys, ridges, penetrations (vents, chimneys, skylights) must match the roofing material (metal flashing for metal roofs, lead or copper for tile or slate). Submit a one-page spec sheet with your permit application; most over-the-counter approvals don't require architectural drawings, but clarifying this with the Building Department upfront avoids delays.

Material changes trigger structural review. If you're switching from asphalt shingles to clay tile or concrete tile, or from asphalt to standing-seam metal, the structural load increases significantly. IRC R905.2 requires the roofer to confirm the existing deck can handle the new weight; for tile (which can exceed 16 psf), you may need a structural engineer's letter. Paris doesn't require this for metal (which is lighter than shingles in most cases), but the Building Department will request it for tile or slate. If your application includes a material upgrade to tile and you don't submit structural verification, the permit will be marked conditional pending that review. Budget an extra 2–3 weeks and $300–$800 for a structural engineer's site visit and letter if tile is in the plan.

Owner-builder status and contractor licensing matter in Paris. Texas allows owner-occupants to pull permits for work on their primary residence without a licensed contractor; this is valid in Paris as well. However, if you hire a roofer to do the work, that contractor must hold a current Texas roofing license (TREC — Texas Roofing, Insulation & Siding Contractors' Board, or equivalent). Many roofers pull permits on behalf of homeowners; confirm your contractor will include permit in their quote. If a contractor refuses to pull a permit or suggests skipping it, that's a red flag — they may lack proper licensing or insurance. For owner-builder work, you'll be the permit holder and attend the inspections; the Building Department may ask proof of ownership and occupancy.

Inspection sequence and timeline: submit your permit application with roof measurements, existing layer count (documented with photos), new material specs, and flashing details. Over-the-counter approval typically happens same-day or within 24 hours for routine like-for-like reroof; plan-review cases (material change, structural concerns, missing specs) take 3–7 business days. Once approved, you have 180 days to start work (standard in Texas). Inspections are triggered at two points: (1) deck framing, after tear-off but before underlayment is laid (Building Department checks nail pattern, deck condition, moisture, structural integrity), and (2) final, after all roofing and flashing is complete. Call ahead to schedule inspections; the Building Department may coordinate directly with your contractor or require homeowner notification. Budget 1–2 weeks for the whole process if you're doing a straightforward like-for-like asphalt reroof on a single-story home; add 2–4 weeks if structural review or architectural drawings are needed.

Three Paris roof replacement scenarios

Scenario A
Two-layer asphalt shingle tear-off and replacement, single-story home in central Paris (3A zone), no structural changes
You're replacing a 1,500 sq ft asphalt shingle roof with the same material (e.g., GAF Timberline to IKO Dynasty). The existing deck has two layers of asphalt shingles; you're doing a complete tear-off down to the wood decking. This is a straightforward permitted scope under IRC R907. You'll submit a one-page application listing the existing material (2-layer asphalt), new material (architectural asphalt shingles), square footage (1,500), tear-off plan, and underlayment spec (e.g., Synthetic U30, 30-year rating). Underlayment and 12-inch ice-and-water-shield are required; flashing details (if any valleys or skylights) must be specified. The Building Department will approve this over-the-counter, typically within 24 hours — no additional drawings or engineer letter needed. Permit cost is $150–$250 (based on ~$1.50–$1.75 per square foot). Schedule a deck-inspection after tear-off and before underlayment installation; final inspection after roofing is complete. Timeline is 1–2 weeks total (permit approval + tear-off + re-roof + inspections). No structural concerns.
Permit required | Over-the-counter approval | 2 inspections (deck, final) | Estimated permit: $180–$250 | Material + labor: $6,000–$9,000 | 7–10 business days start to finish
Scenario B
Upgrade to standing-seam metal roof, same 1,500 sq ft, north Paris (4A zone), existing two-layer asphalt, no skylights
You're replacing two-layer asphalt with standing-seam metal (lighter weight, better longevity). Material change doesn't require structural engineer letter in Paris for metal (metal is lighter than asphalt and doesn't exceed deck capacity), but you must specify: existing tear-off (2-layer asphalt), new material (e.g., Vicwest or Nucor standing seam, 24-gauge), fastening pattern (clips per manufacturer, typically 2-foot spacing), and underlayment (vapor-permeable synthetic, e.g., Grace Ice & Water Shield or Titanium or Metroflashing UDL). Ice-and-water-shield requirement shifts to 24 inches from the eave (4A zone — more stringent than 3A). Flashing at penetrations (if any) must be metal-compatible (painted steel or aluminum, not lead-based). This is a plan-review case, not over-the-counter, because the material change requires Building Department confirmation that underlayment and fastening are correct. Allow 5–7 business days for review. Permit cost is $200–$300 (metal reroofs are often charged at a slightly higher rate because of the fastening review). Inspections: deck framing (to confirm no structural damage and proper substrate prep), and final. Timeline is 2–3 weeks total. Metal requires more detailed spec than asphalt; be prepared to submit product cut sheets if asked.
Permit required | Plan review (5–7 days) | Material change to metal | 24-inch ice-water-shield (4A zone) | Estimated permit: $240–$300 | Metal + labor: $9,000–$14,000 | 14–21 business days
Scenario C
Partial asphalt shingle repair, 8 squares (800 sq ft), existing 2-layer roof with localized leak, same material
Your roof is leaking in one section (around a chimney flashing or valley). The affected area is roughly 8 squares (800 sq ft), which is 53% of a 1,500 sq ft roof but under the 25% threshold only if the rest of the roof is still sound. Here's the key: if you're NOT tearing off the existing shingles and simply patching over them (nailing new shingles over old), and the existing 2-layer roof is stable, this is a repair exempt from permitting. You can hire a roofer or DIY this work without a permit — no application, no inspections, no fees. HOWEVER, if the tear-off is necessary (the existing flashing is compromised, nailing substrate is soft, or you discover a third layer underneath), then you've crossed into replacement and a permit becomes required. The trick: if you start the work and discover a third layer, you're now in violation of IRC R907.4 (can't have 3+ layers), and the city will require stop-work. The safest approach is to call the Building Department or a roofer and do a quick site visit to confirm you have only 2 layers and can patch without tear-off. If that's confirmed and you're staying under 800 sq ft with no tear-off, no permit needed; if tear-off is required or the existing roof has 3 layers, upgrade to a full permitted reroof. Material change (shingles to metal in a repair) also triggers permitting, so stay with matching asphalt shingles to keep this exempt.
No permit required (repair, <25%, no tear-off, like-for-like) | Confirm 2-layer max before starting | ~$2,000–$3,500 material + labor | No inspections | Same-day/next-day completion possible | If tear-off needed, escalates to Scenario A permit required

Paris climate zones and ice-and-water-shield requirements

Paris, Texas spans two IECC climate zones: 3A (most of the city) and 4A (panhandle areas and northernmost parts). Climate zone determines ice-dam risk and flashing requirements. Zone 3A has mild winters with rare sustained freezing; ice dams are uncommon but occasional ice can form at the eave. Zone 4A (panhandle) has longer, colder winters and more frequent ice-dam conditions. The Texas Building Code, which Paris adopts, mirrors IECC requirements: zones with sustained sub-freezing temperatures need ice-and-water-shield extended further up the roof to prevent ice-dam leakage.

For central Paris (3A), ice-and-water-shield must extend at least 12 inches from the eave, or one full course up from where the roof meets the exterior wall (whichever is greater). This protects against occasional ice-dam overflow. For north Paris (4A), extend to 24 inches or two courses minimum. Inspectors will measure this during the final inspection — if you install only 12 inches in a 4A property, the permit may be marked incomplete. When you apply, state your address and ask the Building Department to confirm your exact zone; they can do this in minutes and clarify the requirement. If you're unsure, use the more stringent 24-inch standard; it doesn't add much cost and avoids re-inspection delays.

Water intrusion from ice dams can cause attic mold, rafter rot, and insulation damage — expensive problems that insurance often denies if ice-dam prevention wasn't up to code. This is why inspectors check it so carefully. On your permit application, specify the ice-and-water-shield product by name (e.g., 'Grace Ice and Water Shield, 3-foot roll, applied 24 inches from eave' or 'IKO ArmourGard, 36-inch width'); don't just say 'ice and water shield as required' — be specific so there's no ambiguity during final inspection.

Permitting workflow and over-the-counter vs. plan-review timelines in Paris

The City of Paris Building Department handles permits without a dedicated full-time plan-review division; most review is done by the building inspector or permit technician. This is typical for smaller Texas cities and actually works in your favor for routine roofing: like-for-like asphalt reroof jobs are often approved over-the-counter (same day or next morning) because there's minimal risk and the inspector can eyeball the specs without lengthy deliberation. Material changes (shingles to metal or tile), structural concerns, or missing specs bump you into a 3–7 day review cycle.

To expedite approval, submit a complete application packet: permit form, roof measurement (total square footage and breakdown by slope if multi-pitched), existing layer documentation (photo showing current material and condition), new material name and spec sheet, underlayment product name, ice-and-water-shield requirement statement (with climate zone), and flashing details. Include the contractor's license number if a contractor is pulling the permit. When you call to submit or drop off, ask the permit technician: 'Is this over-the-counter or do you need plan review?' For like-for-like, you'll likely hear 'over-the-counter, back tomorrow morning.' For material changes or structural concerns, expect 'plan review, 3–5 business days.'

Once approved, you'll receive a permit number, approval letter, and inspection request forms. Post the permit placard on the jobsite (usually a card stapled to a window or door frame). Call or email the Building Department to schedule inspections — don't assume they'll show up unannounced. Deck inspection (after tear-off, before underlayment) typically takes 24–48 hours to schedule; final inspection can be scheduled during the roofing stage or after completion. Some inspectors prefer to do final the day after roofing is done (while they can still see all the details clearly); others will come within a week. Budget 1–2 weeks for the whole permitting plus inspection cycle on a straightforward job, longer if you have structural or material-change concerns.

Common questions

Does Paris require a permit for gutter and flashing repair only?

No. Gutter replacement, downspout work, and flashing-only repairs (not involving roof membrane replacement) are exempt from permitting. However, if flashing repair requires roof tearback or if you're replacing flashing as part of a roof replacement, that's part of the roof permit scope. Call the Building Department if you're unsure whether your flashing work is standalone or bundled with roofing.

What if I discover a third layer of roofing during tear-off?

Stop work immediately and call the Building Department. IRC R907.4 prohibits a third layer; you must tear off all existing material down to the deck before continuing. The city will likely issue a stop-work order if they find a third layer mid-project without prior permit approval for full tear-off. This is why pre-permit layer inspection is critical — confirm layer count before submitting your application or starting any work.

Does my roofer's license matter if I pull the permit myself as an owner-builder?

As an owner-occupant, you can pull the permit yourself without a licensed contractor if you're doing the work or closely supervising. However, if you hire a roofer to do the labor, that contractor must hold a valid TREC or equivalent roofing license. The city typically won't ask, but if there's an issue (quality complaint, insurance claim), lack of contractor licensing can complicate matters. Confirm your roofer is licensed before hiring.

How much does a roof permit cost in Paris?

Permits typically range from $150–$300, calculated at approximately $1.50–$2.50 per square foot of roof area, or a flat rate based on scope. A 1,500 sq ft roof costs ~$225–$375. Material changes (asphalt to metal) or cases requiring plan review may be charged at the higher end. Call the Building Department with your square footage for an exact quote.

Can I install a metal roof directly over my existing asphalt shingles?

Overlay of metal over asphalt is possible if there are only two existing layers and the deck is sound. Most roofers and inspectors prefer tear-off for longevity and to eliminate weight-and-moisture issues. If you want to overlay, confirm with the Building Department that your two-layer deck can handle the added weight (usually fine for metal, which is lighter than tile). The permit will be marked 'overlay' and inspections will check the existing roof condition and fastening into solid substrate.

What if I'm reroofing and upgrading to hurricane straps or wind-resistant shingles — do I need special permits?

No separate permit for hardware upgrades, but if you're adding structural reinforcement (like hurricane straps or collar ties), that's a different scope and may require structural drawings. For wind-resistant shingles (Class A or D-rated), those are part of the roofing spec and noted in the permit application; inspectors will verify proper fastening and nailing pattern during inspection. Confirm with the Building Department if you're planning any structural upgrades alongside the reroof.

How long do I have to complete my roof replacement once the permit is approved?

Texas standard is 180 days from permit issuance to start of work; if you exceed this without extension, the permit expires and you must reapply. Once work starts, you typically have 6–12 months to finish, but confirm with Paris Building Department. If delays occur, request a permit extension in writing before the deadline.

Will my homeowner's insurance cover unpermitted roofing work?

Most homeowner policies require permits for roof replacement; unpermitted work may void coverage for that loss or even the entire policy. If you have a claim (hail, wind damage) and the insurer discovers unpermitted roofing, they can deny it outright. This is one of the biggest financial risks of skipping permits — don't gamble with your insurance.

Do I need a structural engineer's letter if I'm changing from asphalt shingles to metal?

No — metal is lighter than asphalt and doesn't require structural review in Paris. If you're upgrading to clay tile or concrete tile, then yes, a structural engineer must confirm the deck can handle 16+ psf; budget $300–$800 and 1–2 weeks for that review. For metal, no engineer letter is needed unless the deck is visibly damaged or sagging.

Can I submit my roof permit application online or by email?

Confirm with the City of Paris Building Department directly — they may accept email submissions or have an online portal (check paristexas.com). Many smaller Texas cities still prefer in-person or phone submission for clarity. Call (903) 732-8000 or visit City Hall to confirm their preferred method and whether they'll process same-day if you submit in person.
