What happens if you skip the permit (and you needed one)
- Stop-work orders from Clovis Code Enforcement can result in $300–$500 fines per day until the permit is pulled and deck inspection passed retroactively.
- Your homeowner's insurance may deny claims for roofing leaks or wind damage if the re-roof was unpermitted, leaving you liable for repairs ($5,000–$25,000 for full deck replacement).
- Seller's Disclosure (required at sale in NM) must list all unpermitted work; buyer can demand a price reduction or walk away, costing you 2–5% of sale price in lost negotiating power.
- Lender refinance will flag unpermitted roof work on title search; FHA and VA loans explicitly require permits for roofing, blocking your refi or requiring expensive remediation.
Clovis roof replacement permits — the key details
The foundational rule is IRC R907, which Clovis has adopted directly: any re-roofing project (defined as replacing 25% or more of the roof area, or any full tear-off-and-replace, or any change of material) requires a permit and at least two inspections. The first inspection occurs after the roof deck is exposed (or after removal if you're tearing off) to verify deck nailing per IRC R905.2.2 (typically 6 inches on-center for typical residential metal or asphalt). The second (final) inspection is after installation of the roofing material and all flashing. Clovis Building Department references the 2021 International Building Code (IBC 1511 and IRC R905-R908 for roofing) as the adopted standard. If your existing roof has three or more layers, IRC R907.4 mandates a complete tear-off — no overlay permitted. This is where homeowners often get surprised: the city will not issue an overlay permit if the field verification shows three layers, even if the original building permit from 1985 claimed two. You will be required to tear off all existing material and dispose of it properly (Clovis landfill accepts roofing waste; see Curry County Solid Waste section for tipping fees). The tear-off adds $1.50–$3.00 per square to your total cost.
Clovis' high desert climate (4B-5B, 5,000+ feet elevation, 24–36 inch frost depth, annual precipitation 14–18 inches with hail risk) creates two specific code amendments relative to other New Mexico cities: ice-and-water shield is required minimum 24 inches from the eave in all valleys and on all north-facing slopes — this is stricter than the standard 6 inches in the IRC baseline and reflects Clovis' freeze-thaw cycles. Second, wind rating is critical: asphalt shingles must be rated ASTM D3161 Class H (120 mph) minimum; some areas of Clovis in Curry County's Wildland-Urban Interface are subject to additional wind exposure, requiring impact-rated shingles or metal. Your roofer should know whether your property sits in a designated wind-exposure zone (the Building Department can confirm). The caliche layer and expansive clay soil in Clovis mean that gutter and drainage systems require proper slope and termination (IRC R903.3 on water management) — failed gutters can cause ponding, which Clovis inspectors will flag as a code violation at final inspection.
Exemptions are narrow and must meet ALL of the following: the work must be repair (not replacement), must affect less than 25% of the roof area, must not change material type, and must not require deck nailing or structural repair. Patching a few shingles, replacing flashing on a single wall, or sealing a small leak are exempt. Re-covering a 30% section of roof with new shingles of the same type? Permit required. Changing from asphalt to metal? Permit required — material change always requires a permit, regardless of square footage, because metal has different attachment and wind-resistance requirements. Some homeowners ask if 'just adding drip edge' is exempt: if you're adding drip edge as part of the re-roof process, it's considered part of the re-roof and the whole project requires a permit. If you're adding drip edge to an existing roof as a standalone upgrade (no shingle replacement), it's usually exempt. Gutters and downspouts are exempt unless they're part of a larger water-management modification tied to the roof replacement.
Clovis' online permit portal (accessible via the city's website under 'Building Services' or 'Permits') requires you to upload: a completed residential building permit form (available as a PDF download), a roof-area calculation (in squares — one square = 100 sq ft), a material specification sheet (brand, type, wind rating, color), a copy of the contractor's license (if applicable), proof of homeowner's insurance, and a site photo showing the existing roof condition. If you're doing the work yourself (owner-builder), you must include a declaration that you own the property and will perform the work personally — Clovis allows this for owner-occupied homes but not for investment properties. The city typically accepts roofing permits over the counter (OTC approval same day) for like-for-like asphalt-to-asphalt re-roofs with no structural issues; tear-off projects, material changes, or multi-layer scenarios go to full plan review (3–7 days). Once approved, the permit is valid for 180 days. You must have the roof inspection scheduled at least 24 hours in advance by calling the Building Department.
The inspection sequence matters for your timeline and budget. After tear-off (if required), the deck is inspected for rot, missing or split sheathing, and nailing pattern — if the inspector finds rot affecting more than isolated patches (say, 5% of the deck), you'll need to budget for underlayment replacement ($0.50–$1.00 per sq ft). Once the deck passes, you can install underlayment and begin roofing. A second inspection occurs after all roofing material and flashing are installed but before cleanup. The inspector will walk the roof to verify fastening density (typically 4 fasteners per shingle, 8–10 inches from butt), proper overlaps, ice-and-water shield placement (24 inches minimum in valleys), and flashing detail. Common rejection points: fasteners not visible or spaced too far apart; valleys not sealed properly; ice-and-water shield cut short of the required 24-inch line in this climate; gutter hangers not reinstalled to code; skylights or vents flashed improperly. If the inspector finds a defect, they issue a 'Notice of Deficiency' and you have 14 days to correct and reschedule. Plan for 2–3 inspections if there are any complications.
Three Clovis roof replacement scenarios
Clovis' high-altitude and freeze-thaw climate: why ice-and-water shield requirements are stricter here
Clovis sits at approximately 4,700 feet elevation in the high plains of eastern New Mexico, with a 4B-5B climate zone (average winter low -5°F, occasional dips to -20°F, and 24–36 inch frost depth). The standard IRC R905.1.1 specifies ice-and-water shield six inches from the eave on unheated spaces; Clovis Building Department amendments extend this to 24 inches minimum in all valleys and on north-facing slopes. Why? The freeze-thaw cycle is aggressive here: daytime sun melts snow on south-facing roofs, meltwater runs down to the eaves (colder, shadowed areas), and freezes at night, creating ice dams. If ice-and-water shield doesn't extend far enough up-roof, water seeps under the shingles and into the attic. Clovis inspectors specifically look for the 24-inch line at final inspection and will flag any ice-and-water shield installed less than 24 inches up-roof as a deficiency.
The city's soil conditions (caliche, expansive clay, volcanic) also drive this requirement: caliche is a hard calcium carbonate layer that sits 2–4 feet below grade in most of Clovis, creating drainage challenges. Gutters and downspouts that fail to direct water away from the foundation can cause ice pooling on the roof edge and gutter overflow into the attic soffit area — another failure mode the 24-inch ice-and-water shield mitigates. When you're planning a roof replacement, budget for synthetic ice-and-water shield (e.g., Peel-and-Stick Cetco, Grace Ice & Water Shield) at roughly $0.50–$0.75 per sq ft; for a 28-square roof with 24-inch valleys and north-slope coverage, that's 8–10 squares of ice-and-water shield, or $400–$600 in materials.
Hail is another climate driver: eastern New Mexico is in the 'hail alley,' with spring and early-summer hailstorms common. Clovis inspectors are familiar with hail-damage claims and will require impact-rated shingles (ASTM D3161 Class 4 or Class H) if a re-roof is occurring after major hail. While not strictly mandated by code for all re-roofs, the Building Department may recommend it and your insurance may offer a discount (5–10% premium reduction) for impact-rated shingles. Metal roofing, popular in Clovis for this reason, must be impact-rated as well and requires stainless-steel fasteners to prevent rust if the roof gets dinged during future hail storms.
Clovis' three-layer rule and why the City won't grandfather old overlay permits
IRC R907.4 states that if a roof has three or more existing layers, a tear-off is required — no overlay permitted. Clovis Building Department enforces this strictly, regardless of when the original layers were installed. Here's the surprise: many Clovis homes built in the 1970s–1990s had roofs applied as overlays (layer on top of layer) because the previous homeowners did unpermitted work or because the city didn't enforce the three-layer limit strictly decades ago. When you apply for a permit today, the inspector will often conduct a pre-permit field verification or require you to do an attic inspection to prove the layer count. If the inspector finds three or more layers in the field (visual inspection from the attic side, counting shingle butt lines, or by extracting a shingle sample), the city will not issue an overlay permit — you will be required to tear off all layers, no exceptions. The cost difference is significant: an overlay (no tear-off) runs $4,000–$6,000 for a 20-square home; a tear-off-and-replace runs $6,000–$9,000. Homeowners who hoped to save money by overlaying sometimes get hit with this surprise at plan review.
Why the strict enforcement? Structural integrity and inspection accessibility are the reasons cited by Clovis code officials. Three layers of asphalt shingles add 15–20 pounds per square to the roof load; if the deck was built to support two layers (typical for homes from the 1950s–1980s), adding a third layer creates a safety risk, especially in high-wind zones or if the deck has any existing rot or weakness. Additionally, once three layers are in place, it's nearly impossible for an inspector to assess the condition of the underlying layers or the deck itself — a potential hazard if the deck is failing. The city prioritizes this inspection point in its three-layer rule. If you're buying a home in Clovis with multiple layers visible, ask the seller for documentation of the previous roof permits; if there's no documentation and the attic inspection shows three or more layers, budget for a tear-off when you plan your roof replacement.
Owner-builders (homeowners doing their own re-roof) still must comply with the three-layer rule and still require a permit. Clovis allows owner-builder permits for owner-occupied residential homes, but the inspector will still conduct the layer-count verification, and if three or more layers are found, the owner-builder must perform the tear-off themselves (the city won't allow an exemption from the tear-off requirement, though the owner-builder can hire a tear-off crew separately). This is an important clarification: 'owner-builder' doesn't mean 'no permit' or 'no inspection' — it means you, the homeowner, are signing the permit and taking responsibility for code compliance, but the City of Clovis still inspects the work. Plan accordingly.

Common questions
Do I need a permit if I'm just replacing a few shingles or patching a leak?
No, if the repair affects less than 25% of the roof area (about 5 squares for a 20-square roof) and does not require deck work or material change, you don't need a permit. However, if you discover deck rot or structural damage during patching, you must stop and contact the Building Department — that triggers a permit requirement for deck repair. Always notify your insurance of repairs so the work is documented.
The previous owner overlaid the roof twice already. Do I have to tear off all layers?
Yes. If an attic or field inspection reveals three or more layers of shingles, Clovis Building Department will require a complete tear-off — no overlay permitted under IRC R907.4. This applies regardless of when the previous layers were installed or whether they had permits. Budget an additional $2,000–$3,000 for tear-off and disposal. Ask for a pre-permit walkthrough from the Building Department to confirm the layer count before you apply for the permit so there's no surprise at plan review.
I want to switch from asphalt shingles to metal roofing. Is that a big deal for the permit?
Yes, a material change always requires a permit and triggers full plan review (5–7 days) rather than over-the-counter approval. Metal roofing has different fastening requirements, wind ratings, and underlayment specifications than asphalt. You'll need to provide the material spec sheet with wind rating (150 mph minimum recommended in Clovis' high-wind zones) and may need a structural engineer's letter if the deck requires reinforcement. Permit fee is typically $200–$300 for material changes. The inspection process is more detailed, with 4–5 inspection points instead of the usual 2–3.
What's the ice-and-water shield requirement in Clovis?
Clovis requires ice-and-water shield 24 inches minimum from the eave on all north-facing slopes and in all valleys — stricter than the standard IRC six inches. This is because of the freeze-thaw cycles and hail risk in the high-altitude climate. Budget $0.50–$0.75 per sq ft of ice-and-water shield; for a typical home, this is $400–$600 in materials. Even exempt repairs are expected to comply with this requirement if they're in a valley or on a north slope.
Can I do the roof replacement myself (owner-builder) without a contractor?
Yes, Clovis allows owner-builder permits for owner-occupied residential homes. You'll file the permit application yourself, sign a declaration that you own the property and will perform the work personally, and the Building Department will conduct the same inspections as a contractor job. However, if the field inspection reveals three or more layers, you still must tear off all layers — the city won't exempt owner-builders from the tear-off requirement, though you can hire a tear-off crew to handle that portion. Permits are not allowed for investment properties.
What happens at the deck inspection, and what causes rejections?
After tear-off (or after removal of old shingles), the inspector examines the deck for rot, missing or split sheathing, and nailing pattern per IRC R905.2.2 (typically 6 inches on-center). If rot is limited to isolated patches (<5% of deck), you can patch those areas. If rot is widespread, you may need to replace sections of sheathing, which adds $1–$3 per sq ft. Common rejections: nailing too sparse, split or cupped sheathing, deck settlement or sag (a sign of structural issues), or missing nails. If rejected, you have 14 days to correct and reschedule the inspection.
How long does the whole permit and roof replacement process take in Clovis?
For a like-for-like asphalt re-roof with no tear-off needed, the permit is issued same-day or next-business-day (OTC), and inspections can be scheduled within 1–2 weeks, giving a total timeline of 2–3 weeks from filing to final inspection. For a tear-off or material change, plan review takes 5–7 business days, and the total timeline is 3–4 weeks. Your roofer must schedule inspections 24 hours in advance by calling the Building Department.
What's the permit fee for a roof replacement in Clovis?
Permit fees typically range from $75–$150 for like-for-like asphalt re-roofs and $150–$300 for tear-offs or material changes. The fee is usually calculated based on roof area in squares (one square = 100 sq ft). A 20-square like-for-like re-roof might be $100; a 28-square tear-off with metal roofing might be $250–$300. Call the Building Department or check the online portal for the current fee schedule.
Do I need impact-rated shingles in Clovis?
Impact-rated shingles (ASTM D3161 Class 4 or Class H) are not mandated by code for all re-roofs, but they're strongly recommended in Clovis because of the hail risk (Curry County is in 'hail alley'). Your insurance company may offer a 5–10% premium discount for impact-rated shingles, which can offset the higher material cost ($0.50–$1.00 per sq ft more than standard shingles). Metal roofing is also popular for hail resistance and must be impact-rated. The Building Department will recommend impact-rated shingles if a re-roof is following major hail damage.
What if I discover I have an unpermitted roof from a previous owner?
If you're selling the home, New Mexico Seller's Disclosure law requires you to disclose unpermitted work (including roofing). The buyer can request a price reduction or demand remediation before closing. If you're staying in the home and planning a roof replacement anyway, the new permit and inspection will bring the roof into code compliance going forward — the prior unpermitted work can't be retroactively permitted, but the replacement permit is a fresh start. If you discover unpermitted roofing while refinancing, your lender (FHA, VA, conventional) may require proof of a new permit and final inspection before approving the refi. Don't ignore unpermitted roof work; it creates liability and resale complications.
