The Short Answer
A full roof replacement in Hudson requires a permit from the City of Hudson Building Department. Partial repairs under 25% of roof area and like-for-like patching may be exempt, but any tear-off-and-replace or material change triggers permitting.
Hudson, Ohio enforces the 2017 IRC standard, and the city's building department processes roofing permits through its online portal with a typical over-the-counter approval for like-for-like replacements (same material, same slope). What sets Hudson apart from surrounding Summit County communities: Hudson explicitly requires a deck inspection report during the permit review if any existing shingles will be removed, and the city flags any roof with three or more existing layers for mandatory tear-off rather than overlay — a rule that catches many homeowners off guard in this area where older homes commonly have 2-3 layer buildup. The city also requires ice-and-water shield extended 24 inches from eaves on any roof, reflecting the region's freeze-thaw cycling and occasional ice-dam risk. Permit fees in Hudson run $150–$300 depending on roof square footage, typically calculated at 1.5–2% of estimated project cost. The city's online portal allows you to upload photos of existing conditions and material specs before submitting, which speeds approval; most like-for-like replacements clear in 5–7 business days.

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

Hudson roof replacement permits — the key details

Hudson requires a permit for any full roof replacement, any tear-off-and-replace (regardless of size), any material change (shingles to metal, shingles to tile, etc.), or any replacement exceeding 25% of the roof area. The trigger is in IRC R907.4 and the city's local adoption: if you are removing existing roofing to expose the deck, you need a permit. If you are pulling more than three layers of shingles, Hudson's building department mandates a full tear-off — overlays are not allowed over three layers. The city also requires you to submit a pre-permit deck inspection report if the existing roof is 2+ layers; this report certifies the deck is sound (no rot, no sagging) and meets fastening requirements. Many roofers skip this step and homeowners end up with a permit denial and a contractor sitting idle on the roof. The deck inspection is not an extra cost if your roofer uses their own inspector; if you hire a third party, budget $150–$250. Like-for-like replacements (asphalt shingles on an asphalt shingle roof, same slope, no structural changes) often clear over the counter in 5–7 days; anything involving a material change, a slope change, or structural work triggers a full plan review (10–14 days).

Hudson's climate zone 5A and 32-inch frost depth mean the city enforces strong underlayment and ice-and-water shield rules. IRC R905.1.1 requires ice-and-water shield on any roof, but Hudson's building department specifically requires it extended 24 inches inward from the eaves on all pitches — not just low-slope or special condition roofs. This is critical in Hudson because freeze-thaw cycles and late-season snow melt create ice-dam conditions every 3–5 years; the extra membrane protects the house if shingles fail to shed water properly. Your roofer must specify the exact underlayment product (name, model, rating) on the permit application; generic descriptions like 'standard roofing felt' will result in a request for information. Similarly, fastening patterns are scrutinized: the city requires a copy of the shingle manufacturer's installation guide showing nail type, spacing, and deck fastening schedule. Roofing contractors licensed in Ohio (which most legitimate firms are) know this; unlicensed handyman work often fails because fastening specs are missing from the permit.

Material changes and structural concerns are where Hudson's permitting gets granular. If you are switching from asphalt shingles to metal, stone-coated steel, or tile, you must include a structural engineer's letter certifying the new material weight does not exceed the deck's load capacity. Metal roofing is lightweight and almost never an issue, but clay or concrete tile can be 700–900 lbs/square (vs. 250–350 lbs/square for asphalt), and older homes in Hudson (many built in the 1950s–1970s) sometimes have deck scantling that cannot carry the load. The structural letter costs $300–$600 and adds 5–7 days to the permit review, but it is required by IBC 1511.3 if there is any doubt. If you skip the engineer's letter and the inspection later reveals an undersized deck or inadequate bracing, the city can issue a stop-work order and demand you remove the tile at your expense — a $3,000–$8,000 reversal. Aesthetic upgrades like metal roofing are worth doing right; the structural letter is insurance against that outcome.

Hudson's online portal submission process is straightforward but requires specificity. You upload: a completed permit application (available on the city's website), a roof plan showing dimensions and slope, a materials specification sheet (manufacturer name, product code, color), the deck inspection report (if applicable), photos of the existing roof, and — for material changes — the structural engineer's letter. The portal flags missing items immediately and typically will not allow submission until all required documents are attached. Once submitted, the city sends an email confirmation within 24 hours. Over-the-counter approvals (same material, sound deck, no changes to slope or penetrations) are issued the same day or next business day; full plan reviews go to a roofing specialist and take 7–14 days. Hudson does not charge for resubmissions if you add missing info, but every resubmission resets the clock, so get it right the first time. The permit is valid for 180 days; if you do not start work within that window, it expires and you must renew it (no additional fee, just a quick reapplication).

Inspection and approval timing: once your permit is issued, you can schedule the work. Hudson requires an in-progress inspection (deck nailing/fastening check) if you are doing a full tear-off; this is typically done after the old roof is stripped and the deck is exposed, before new underlayment goes down. The inspector checks nail spacing, deck condition, and flashing details. For overlay work (if the roof has fewer than three layers and is in excellent condition), the in-progress inspection is sometimes waived for like-for-like asphalt-to-asphalt jobs, but the city reserves the right to inspect anyway. Final inspection must happen after all roofing is installed, flashing is sealed, and cleanup is done. The inspector verifies material type, fastening pattern compliance, underlayment integrity, ice-and-water shield placement, and flashing seal. If everything passes, you receive a Certificate of Occupancy for the roof (or a permit sign-off if no CO is required for the work). If issues are found, you get a punch list and have 14 days to correct them before a reinspection. Most roofing jobs pass final inspection on the first try if the contractor is licensed and followed the permit specs. Budget 1–2 hours per inspection; the city typically schedules within 2–3 business days of your call or online request.

Three Hudson roof replacement scenarios

Scenario A
Full asphalt-to-asphalt shingle replacement, 1,800 sq ft, single-layer existing roof in good condition, Stow-style ranch in Hudson proper
You have a 1980s-era ranch with a single layer of 25-year-old architectural shingles showing granule loss and curling. You want to replace with new 30-year architectural shingles, same slope (6/12 pitch), no structural changes. This is a classic like-for-like case and Hudson approves it over the counter. You submit a permit application with roof dimensions (18,000 sq ft of living space, 1,800 sq ft of roof), the manufacturer's spec sheet for your chosen shingle (e.g., Owens Corning Duration 30-year, color Architectural Gray), and photos of the existing roof. Because there is only one layer, Hudson waives the deck inspection report. You submit on a Monday morning; the city reviews it the same day and emails approval by 3 PM. Permit fee is $200 (roughly 1.5% of the $13,000 estimated project cost). Your licensed roofer can start work immediately. An in-progress inspection happens after the old roof is stripped — the inspector checks deck fastening and any spots where the old roof was nailed directly to the underlying sheathing without a gap (common in older homes, and sometimes causes rust stains or nail pops in the new roof). The inspector signs off on deck condition in 30 minutes. Work resumes, new underlayment and shingles go down over 2–3 days. Final inspection is scheduled; the inspector verifies shingle fastening density (typically 4–6 nails per shingle per IRC R905.2.7), underlayment overlap, ice-and-water shield extended 24 inches from eaves, and flashing caulked and sealed. Pass, permit closes, you're done. Total timeline: 10–14 days from permit issuance to final sign-off, including work days.
Permit required | $200 permit fee | Deck inspection waived (single layer) | Ice-and-water shield to 24 inches required | No structural letter needed | Over-the-counter approval 1 day | Final inspection 1–2 hours | Total project cost $12,000–$16,000
Scenario B
Asphalt-to-metal roof replacement, 2,100 sq ft, two existing layers (asphalt + tar paper), Colonial in Summit County jurisdiction near Hudson, slope change from 6/12 to 7/12 proposed
You own a 2000s Colonial in an unincorporated Summit County area near Hudson; the county follows the same 2017 IRC but with slightly different administration. Your existing roof has two layers of asphalt shingles plus an old tar-paper underlayment. You want to upgrade to a standing-seam metal roof and are also increasing slope from 6/12 to 7/12 by adding strapping. This is a material change plus a structural modification, so Hudson-area permitting (or the county equivalent) requires a full plan review plus a structural engineer's letter. The metal roof itself is light (50–80 lbs/square), so the slope increase does not overload the deck, but the engineer's letter certifies this and shows the new roof load on the plan. You submit a permit with: roof plan showing old and new slopes, the metal roof manufacturer's spec sheet (e.g., Standing Seam, 26-gauge Galvalume, 24-inch panel width), the deck inspection report (required for two layers), the structural engineer's letter, and photos. The building department issues a request for information: they want the roofer's flashing detail plan (how the metal panels will connect at the ridge, valleys, and eaves). Your roofer supplies this within 2 days. Full plan review then takes 7–10 days. Permit fee is $280 (based on roof area and material change surcharge). The city wants to ensure the slope change does not affect gutters or create drainage issues, so they may request a site plan showing gutter routing. Once approved, an in-progress inspection is mandatory after tear-off and deck prep (checking for rot, nail fastening, and strapping installation). The inspector verifies the new strapping is properly sized and fastened to the deck. Another in-progress happens after underlayment and before the metal panels go down. Final inspection checks metal panel fastening, sealing at penetrations, flashing details, and ridge/valley alignment. Budget 4–6 weeks from permit issuance to final approval if the structural letter is ready upfront. If the engineer needs time, add 1–2 weeks.
Permit required | $280 permit fee | Structural engineer letter required ($400–$600) | Deck inspection required ($0 if roofer's inspector, $150–$250 if hired) | Full plan review 7–10 days | Two in-progress inspections | Material change and slope change | Metal roof install 3–5 days | Total project cost $18,000–$26,000
Scenario C
Repair of 300 sq ft wind-damaged section, partial tear-off and re-cover, three existing layers (limit repair scope to avoid full strip), Hudson historic district
You have a 1960s Cape Cod in Hudson's historic district (which includes parts of downtown and the neighborhood near the library). A windstorm damaged about 300 sq ft of the roof on the east slope — about 17% of the total roof area. Your roofer says they can patch it by removing the damaged shingles and the two layers underneath that section, then re-cover with new asphalt shingles. Since the work is under 25% and it is a tear-off-and-replace of a discrete section, Hudson technically allows it as a repair permit rather than a full re-roof permit. However, the historic district overlay adds a complication: the Historic District Review Board may require approval of roof changes, including material, color, and visible profile. You must check with Hudson's Planning Department before filing the roofing permit. If the repair can use the same shingle type and color as the existing roof, the HDC usually approves it by administrative review (5–7 days). If you want to switch materials (e.g., upgrade to a higher-grade shingle or a different color), the HDC may require a full review meeting (2–3 weeks). Once HDC approves, you file the roofing permit with the Building Department, documenting that the three-layer discovery in the repair section will trigger a deck inspection. The Building Department then either issues a permit for the limited repair or, upon closer inspection of the rest of the roof, may recommend a full tear-off (if deterioration is visible elsewhere). Permit fees for a partial repair are $120–$180. The inprocess and final inspections are the same as for a full roof, but only the repair area is inspected. Total timeline: 2–4 weeks if HDC approval is quick, 5–8 weeks if a meeting is required. The permit is conditional on no additional damage being discovered during tear-off; if the roofer uncovers rot or structural issues, the scope may expand and the city may mandate a larger repair.
Repair permit required (under 25% area) | Historic District overlay approval required | $150–$180 permit fee | HDC administrative review 5–7 days (likely) | Deck inspection required | Three-layer discovery may trigger full-tear-off requirement | In-progress and final inspections | Total repair cost $4,000–$8,000

Ice-and-water shield and freeze-thaw in Hudson's climate

Hudson, Ohio sits in climate zone 5A with 32 inches of frost depth and experiences 3–5 significant freeze-thaw cycles per winter, plus occasional ice dams when wet snow falls late in the season and then refreezes at the eaves. The 2017 IRC R905.1.1 requires ice-and-water shield, and Hudson's building department has amended this to require 24 inches of ice-and-water shield from the edge of the eaves on all slopes, not just low-slope roofs. This is a local addition, not found in all surrounding jurisdictions, and it reflects the city's experience with ice-dam damage in the 1990s and early 2000s.

Why does this matter? Standard asphalt shingles shed water poorly in the first 12–18 inches of the roof above the eaves if ice dams form. If water backs up under the shingles and seeps into the attic or insulation, it can cause interior damage, mold, and structural rot. Ice-and-water shield is a self-adhering rubberized membrane that remains pliable in freezing temperatures and creates a seal even if water flows backward. Extending it 24 inches (vs. the IRC minimum of ~12 inches at roof edges) provides a safety margin for Hudson's climate.

During permit review, the city inspector checks that the ice-and-water shield is specified by product name on the application (e.g., 'Owens Corning WeatherLock Ice and Water Barrier, 36 inch wide'). They also verify on final inspection that it is visible along the eave edge and that the seams are overlapped correctly. If your roofer tries to skimp by using felt instead of ice-and-water shield, the permit will be denied or flagged during final inspection. Budget an extra $300–$500 for ice-and-water shield on a typical 1,800 sq ft roof.

One more detail: if your roof has gutters, the ice-and-water shield should extend under the gutter edge so water flowing backward flows into the membrane, not into the attic wall. This coordination is something the inspector checks. If gutters are old or clogged, fix them as part of the re-roof scope.

Material change permits and structural review for tile, slate, or heavy roofing

If you are planning to replace asphalt shingles with clay tile, concrete tile, slate, or any material significantly heavier than shingles, Hudson requires a structural engineer's letter. Asphalt shingles weigh roughly 250–350 lbs per square (a square is 100 sq ft); clay tile weighs 700–900 lbs/square, and concrete tile runs 800–1,200 lbs/square. A typical 1,800 sq ft roof is 18 squares. Going from asphalt to clay tile means adding roughly 8,000–10,000 lbs of weight to the roof structure. Most homes built after 1980 can handle it, but many 1960s–1970s homes in Hudson have roof trusses or rafters sized for 40 lbs/sq ft live load plus shingles, not for 70–80 lbs/sq ft from heavy tile.

The engineer's letter must certify that the existing roof structure (rafters, trusses, collar ties, connections, and load paths to the foundation) can safely carry the new material. The engineer typically charges $300–$600 and requires a site visit plus a review of the home's construction documents (framing plan, if available). The letter becomes part of the permit and is reviewed by the building department. If the structure is inadequate, the engineer will recommend sistering (doubling) rafters or reinforcing collar ties — work that adds $2,000–$5,000 to the project and extends the timeline by 1–2 weeks.

Stone-coated steel roofing and metal shake-profile roofing (a lighter-weight metal designed to mimic traditional shakes) are typically 100–150 lbs/square, so they do not require structural review and are often treated like asphalt replacement. Always confirm with your roofer before planning a material change. If you want tile aesthetics without the weight penalty, metal-tile-profile roofs (installed in Hudson) are a growing option and clear permits faster.

Common questions

Do I need a permit to repair a few missing shingles or a small leak?

No. Repairs of less than 25% of the roof area do not require a permit if you are not removing the underlying layers. Patching a few shingles, replacing flashing, or sealing a leak is exempt. However, if the repair uncovers rot or requires pulling back multiple layers, contact the Building Department to confirm you stay within the exempt threshold. When in doubt, call the city — unpermitted work can become a problem at resale.

My roofer found three layers of shingles when they started work. What happens now?

IRC R907.4, which Hudson enforces, prohibits overlay onto a roof with three or more existing layers. The roofer must stop, inform you, and notify the Building Department. You will need to amend your permit to include a full tear-off (not just the damaged section) or have the work stopped. A full tear-off will increase the scope and cost by 20–30%, but it is required by code. The inspector will ensure all three layers are removed and the deck is inspected before new roofing goes on.

Can I overlay new asphalt shingles over the existing roof without tearing off?

Only if you have one existing layer (or two in some cases) and the deck is in good condition. Hudson will allow a two-layer overlay if the deck inspection confirms no sagging, rot, or structural issues. An overlay avoids tear-off labor but adds weight and may not extend roof life as long as a full replacement. If you have three or more layers, tear-off is mandatory. Overlay also means you cannot change roof slope or repair underlying deck issues.

What if I am upgrading to metal roofing? Do I need a structural engineer?

For most homes in Hudson, no. Standing-seam metal roofing weighs 50–80 lbs/square, which is lighter than asphalt shingles. Metal panels do not require structural review in the Building Department's standard practice. However, if you are also increasing roof slope, changing the roof load path, or your home is a historic structure with uncertain framing, the city may request an engineer's letter. Ask the Building Department upfront when you submit the permit; include a note that the new material is metal and specify its weight.

The permit application asks for a deck inspection report. Can my roofer do it, or do I need to hire a third party?

Your roofer can perform and sign the deck inspection report if they are licensed. No additional fee. If you want an independent inspection (for your peace of mind before committing to the job), hire a home inspector or structural engineer; expect $150–$250. The inspection checks for rot, structural sagging, nail fastening compliance, and deck sheathing condition. Once the report is submitted with the permit, the Building Department may still conduct its own inspection during construction — the deck inspection report does not waive the city's right to inspect.

How long is my roof permit valid if I don't start work right away?

Hudson roofing permits are valid for 180 days (six months) from the date of issuance. If you do not start work within that window, you must renew the permit. Renewal is free; you just submit a quick reapplication and the permit is reissued for another six months. If more than 180 days have passed and conditions have changed (e.g., new code adoption, material discontinuation), the city may require updated specs.

What happens if I hire an unlicensed roofer and they pull a permit in my name?

You become responsible for the permit and the work. If the unlicensed roofer installs the roof incorrectly (wrong fastening, missing ice-and-water shield, poor flashing), the final inspection will fail and you must pay to have it corrected — often by a licensed roofer, at a higher cost. Unlicensed roofers may not know the current code requirements (e.g., Hudson's 24-inch ice-and-water shield rule) and often cut corners. In Ohio, hire only a licensed roofing contractor; verify their license through the state contractor registration website. Licensed roofers carry liability insurance and are held to code standards.

Can I pull the roofing permit myself as an owner-builder, or must the roofer pull it?

You can pull the permit as an owner-builder if you are the owner of the property and it is owner-occupied. You do not need to be the one doing the work. However, you are responsible for submitting complete specs, scheduling inspections, and ensuring the work meets code. Most homeowners and roofers find it easier to let the roofer (as the contractor of record) pull the permit; they handle the paperwork and inspections as part of the job. Ask your roofer's process upfront.

If I don't get a permit, can the city force me to remove a new roof and reinstall it correctly?

Yes. If you are caught with unpermitted roofing work, the city can issue a stop-work order, require you to remove the new roof, have it reinspected, and sometimes pay fines ($250–$500). The roofer may face license penalties. At resale, Ohio's disclosure law requires you to reveal unpermitted work; the buyer can demand removal, price reduction, or walk away. Most lenders will not finance a home with unpermitted roof work until it is corrected and inspected. It is not worth the risk.

My home is in Hudson's historic district. Do I need extra approval for a re-roof?

Yes. If your home is within a designated historic district, you must submit your roof plan and material choice to the Historic District Review Board (HDRB) before or concurrently with the roofing permit. The HDRB reviews visible roofing materials and color for compatibility with the historic character. For most repairs using the same material and color, approval is administrative and takes 5–7 days. If you want a different color or material, the HDRB may schedule a review meeting, which adds 2–3 weeks. Metal roofing, modern standing-seam, and non-traditional colors sometimes require HDRB approval, so plan accordingly.
