Shingle Roof Replacement in Columbus: Cost, Code and Process

A standard architectural shingle roof on a typical 25-square Columbus house — 2,500 square feet of roof surface, low slope, one story — runs $9,225 to $16,375 on the estimator on this site. Economy 3-tab sits lower and luxury shingles higher; the same roof at a moderate pitch on a two-story house runs $11,159 to $19,807. Tear-off, underlayment, flashing, cleanup and the permit are inside those ranges.

What does a shingle roof replacement cost per square?

Roofers price by the square — 100 square feet of roof surface, not of floor area. Most Columbus houses carry 18 to 35 squares. The planning ranges below come from the rate tables behind the roof cost estimator on this site. They are all-in per square: tear-off and disposal, underlayment and ice barrier, the shingles and the labor to lay them, flashing and valley details, cleanup, and the permit line.

Shingle grade maps onto the three columns the estimator uses. 3-tab is the economy grade, architectural (laminated) is the standard grade, and luxury or designer shingles are the premium grade. Architectural goes on the large majority of Columbus re-roofs, so read the standard column as the default and the other two as the trade-down and the trade-up.

Those figures are built from a fixed block and a grade-scaled block. The fixed block does not change with shingle grade:

• Tear-off and disposal, $50 to $95 per square. Two layers cost more than one because there is twice the weight to move.
• Flashing, valleys and details, $28 to $60 per square. A roof with four valleys, two dormers and a chimney sits at the top of that line; a plain gable ranch sits at the bottom.
• Cleanup and nail sweep, $10 to $22 per square.
• Permit, dump fees and miscellaneous, $9 to $18 per square.

That fixed block totals $97 to $195 per square before a single shingle is bought, which is why a cheap shingle does not make a cheap roof. The grade-scaled block is underlayment and ice barrier at $22 to $40 per square plus shingle material and installation at $250 to $420 per square, and that block is multiplied by 0.88 for economy, 1.00 for standard and 1.25 for premium.

What is not in those ranges: replacing rotten decking, structural repair to rafters or trusses, ventilation upgrades beyond replacing what is there, gutters, skylight replacement, and whatever the deck shows once it is open. Get the per-sheet decking rate in writing before tear-off starts — it is the most common surprise on a Columbus re-roof.

What a whole roof costs, by size

You need a square count, not the size of the house. Measure the footprint, add the garage and porch roofs, then add for overhangs and slope: a 1,200 square foot ranch footprint usually comes out near 14 to 16 squares. The table is architectural shingles at standard grade, low slope (4/12 or less), one story.

Two multipliers move every one of those figures, and they multiply together:

• Pitch. Low, 4/12 and under, is 1.00. Moderate, 5/12 to 8/12, is 1.12. Steep, 9/12 and above, is 1.30. Most Columbus houses built after 1950 are moderate; the older four-squares and Victorians in German Village, Olde Towne East and Clintonville are frequently steep.
• Height. One story is 1.00, two stories 1.08, three or more 1.18. You are paying for staging, ladder work and fall protection, not materials.

Multiply straight through. A 25-square roof at moderate pitch on two stories: $9,225 to $16,375 multiplied by 1.12 and 1.08 gives $11,159 to $19,807. A 30-square roof at steep pitch on two stories: $11,070 to $19,650 multiplied by 1.30 and 1.08 gives $15,542 to $27,589. A floor applies at the bottom of the scale — no job prices below $1,200 at the low end — so a small porch roof does not cost a tenth of a full roof.

"What does a 1,710 square foot roof cost in Columbus?" That is 17.1 squares. At standard grade on a low-slope, one-story roof, 17 squares at $369 to $655 per square is $6,273 to $11,135. Put the same roof on a moderate pitch with two-story wall height and it lands near $7,600 to $13,500.

"What is the average cost of a roof on a 1,600 square foot two-story house?" Watch the units. That is floor area across two floors, so the footprint is roughly 800 square feet and the roof is usually 10 to 13 squares, not 16. Ten squares of standard shingles on a low-slope, one-story roof is $3,690 to $6,550; at moderate pitch on two stories that is about $4,500 to $7,900. Add an attached garage and a porch and the count climbs toward the 15-square row.

These are planning ranges, not quotes. They exist so you can tell whether the three estimates on your kitchen table are in the same universe as each other.

What moves the number in Columbus

Six things account for most of the spread between a low bid and a high bid on the same house.

Pitch

Above roughly 7/12 a roofer cannot stand on the slope without roof jacks and staging, and material has to be carried rather than slid. That is the 1.12 and 1.30 multipliers. Pitch also decides whether shingles are allowed at all: below 2/12 asphalt shingles are not a permitted covering, and a low-slope section needs a membrane instead — the flat roof replacement guide covers those.

Stories

A second story adds 8 percent and a third 18 percent, all of it labor and safety. Access counts too: on a tight lot there may be nowhere to park a dumpster, and swapping a smaller one twice is a line on the bid.

Layers to tear off

One layer is the assumption in the table. A second layer roughly doubles the $50 to $95 tear-off line and adds a day. Ohio caps you at two layers, so a house already carrying two has no overlay option left.

Decking

Nothing above covers new sheathing. Columbus houses built before about 1955 often have plank decking with gaps wider than modern nailing allows, and 1950s-70s ranches often have half-inch plywood delaminated around an old leak. Rot is invisible until the shingles are off, so agree a written per-sheet price in advance.

Ventilation

Ohio requires balanced attic ventilation and a large share of Columbus attics do not have it — soffit vents buried in insulation, a gable vent fighting a ridge vent, a bath fan dumping into the attic. Fixing it during a re-roof is cheap, but it is still an add. Skipping it shortens shingle life and feeds winter ice dams.

The permit and the inspection

Permit and dump fees sit in the $9 to $18 per square line. The cost of not pulling one shows up years later, at sale or on a claim. Columbus and every surrounding jurisdiction require a permit for a full replacement — see the Columbus roofing permits guide.

When does a shingle roof need to be replaced?

A residential asphalt shingle roof in central Ohio typically lasts 20 to 30 years, depending on shingle quality, attic ventilation, exposure and installation. Age alone is not the signal: a roof at 18 years in good shape may have life left, and one at 12 in poor shape needs to come off.

The clearest signs a roof is near the end of its service life:

• Age past 20 years for 3-tab shingles, 25 or more for architectural
• Granule loss — sandy buildup in gutters, bald patches on the slope, granules at the downspout splash zone. The National Roofing Contractors Association lists it among the earliest indicators of shingle failure
• Curling, cupping or clawed edges — the asphalt has dried out and lost flexibility
• Cracked shingles across the field of the roof, not isolated damage
• Repeat leaks in the same area despite previous repairs
• Sagging rooflines — a structural concern; get it inspected immediately
• Moss and algae that will not stay gone after treatment
• Storm damage — wind tears, missing shingles, hail bruising, limb strikes

One missing shingle or a single leaking pipe boot is not a replacement trigger — that is a repair. Replacement makes sense when the assembly is failing, not when one component has a fixable problem. For how the layers work together, see how a residential shingle roof works.

3-tab, architectural or luxury: which grade belongs on your house?

Grade moves the total by a few thousand dollars on a typical Columbus roof, and it changes expected service life more than the brand does.

3-tab (economy, $336 to $600 per square) is a single-layer shingle with a flat look and the lowest wind and impact ratings of the three. It suits a rental, a flip, a detached garage or a house being sold soon. On a 25-square roof the economy column saves roughly $800 against standard at the low end, and that saving is the whole argument for it.

Architectural or laminated (standard, $369 to $655 per square) is two layers bonded together: thicker, heavier, better wind performance, a dimensional shadow line, a longer manufacturer term. It is the default on Columbus re-roofs.

Luxury or designer (premium, $437 to $770 per square) is a heavier laminate shaped to imitate slate or shake, and where impact-rated Class 4 products usually live. On a 25-square roof it adds roughly $1,700 over standard at the low end — worth it where the roof is a visible part of the elevation, where an insurer discounts Class 4, or where a historic district expects a profile.

For the profile-by-profile comparison, read 3-tab vs. architectural vs. luxury shingles. If you are weighing asphalt against a longer-life system, the metal roof replacement guide has the same cost tables for standing seam and metal shingles.

Worth saying plainly: grade matters less than installation. A premium shingle over rotten decking, with reused flashing and a starved attic, fails before a standard shingle installed correctly.

Tear-off vs. overlay: what Ohio code allows

When you replace a shingle roof there are two paths.

1. Tear-off (full replacement) — strip everything to the deck, inspect and repair the sheathing, then install all new underlayment, ice and water shield, flashing and shingles.
2. Overlay (roof recover) — lay new shingles directly over the existing layer.

Ohio allows both, with limits. Under the reroofing provisions of the Ohio Residential Code (Section R908), a recover is not permitted when the existing roof is water-soaked or deteriorated past serving as a base, when the existing covering is slate, clay, cement or asbestos-cement tile, or when the roof already carries two or more layers.

That last condition is the one that catches people. In Ohio you cannot legally have more than two layers of shingles on a roof. If yours already has an overlay, the next replacement is a tear-off by law. Several Ohio jurisdictions go further and require tear-off outright — Kettering, for example, treats overlay as an option only for a single existing layer over sound sheathing.

Even where an overlay is legal it is usually the wrong economy. The deck stays hidden, so soft sheathing cannot be found or fixed. No new ice barrier goes down, and Ohio requires it from the eave to 24 inches inside the exterior wall line (ORC R905.1.2). Old step flashing, valley metal and drip edge stay, and flashing is where roofs leak. Two layers run hotter than one, so overlays commonly give 15 to 20 years where a tear-off gives 20 to 30 — and manufacturers routinely limit coverage on shingles laid over shingles.

The full arithmetic, including what the saving really is once the next replacement is priced in, is in tear-off vs. overlay.

The replacement process, step by step

A residential tear-off and re-roof in Columbus takes one to three days for an average home, weather permitting. What happens, in order:

1. Inspection and estimate. The roof is measured and documented and a scoped estimate written. Get at least three, each describing the same scope so the numbers compare.
2. Permit. Pulled by the contractor, in the contractor's name, before work starts.
3. Delivery and site protection. Tarps over landscaping, deck, condenser and patio; magnetic sweepers staged.
4. Tear-off. Shingles, underlayment, flashing and pipe boots come off to the bare deck — usually one day on an average house.
5. Deck inspection and repair. Every square foot checked for rot and soft spots, damaged sheathing replaced at the agreed per-sheet rate.
6. Ice barrier and underlayment. Self-adhering membrane at eaves and valleys, then synthetic or felt underlayment across the rest of the deck.
7. Drip edge and flashing. New metal at eaves and rakes, new step and counter-flashing at walls and chimneys, new pipe boots. Reused flashing is the commonest corner cut on a cheap bid.
8. Starter strip and field shingles. A dedicated starter course at eave and rake, then shingles course by course to the ridge.
9. Ridge vent and cap. The slot is cut and the vent set before hip and ridge cap go on; short soffit intake is corrected at the same time.
10. Cleanup and walk-through. Repeated magnetic sweeps of the perimeter, gutters cleared, tarps down, warranty paperwork handed over.
11. Inspection. The inspector verifies the work and closes the permit. Keep the record.

What Ohio code requires on a shingle re-roof

These are the provisions a Columbus inspector actually checks, from the 2019 Residential Code of Ohio, which adopts the International Residential Code with state amendments.

• Asphalt shingles, R905.2. Shingles go on a solidly sheathed deck, only on slopes of 2/12 and above, with double underlayment between 2/12 and 4/12.
• Fastening, R905.2.5. Minimum four fasteners per strip shingle, nails penetrating at least three-quarters of an inch into the deck or fully through thinner sheathing. Six is common on steep and wind-exposed roofs.
• Ice barrier, R905.1.2. Required from the eave edge to at least 24 inches inside the exterior wall line — two courses of 36-inch membrane on most houses, and central Ohio's freeze-thaw cycle is why.
• Underlayment, Table R905.1.1. Must conform to ASTM D226, D4869 or D6757.
• Flashing, R903.2. Required at wall intersections, valleys and every penetration, in corrosion-resistant metal at least 0.019 inch thick.
• Ventilation, R806.2. Net free ventilating area of 1:150 of the attic floor, or 1:300 where intake and exhaust are properly balanced.
• Reroofing, R908. Sets the recover limits above and requires deteriorated decking and flashing to be repaired or replaced.
• Wind resistance. Shingles rated to ASTM D7158 Class G or H, or D3161 Class F, for the Franklin County design wind speed.

Columbus permits, inspections and the CRA tax abatement

The City of Columbus requires a building permit for a residential roof replacement, and so does every surrounding jurisdiction — Upper Arlington, Bexley, Worthington, Grandview, Dublin, Westerville, New Albany. It applies to a tear-off and an overlay alike. The contractor pulls it in their own name; one who asks you to pull it as an owner-builder is moving liability onto you.

The permit triggers an inspection. Some jurisdictions look at the deck and ice barrier after tear-off, most inspect at completion, and the sign-off enters the property record permanently — which is what a buyer's inspector looks for at sale. Fees by jurisdiction and what inspectors check are in the Columbus roofing permits guide.

There is a second reason the permit matters here. Columbus administers Community Reinvestment Areas, a state-authorized program under Ohio Revised Code Chapter 3735 in which qualifying improvements can earn an abatement on the property tax attributable to the added value, often for 10 to 15 years. A permitted roof replacement can qualify; unpermitted work cannot, because there is no record to abate.

Boundaries are set by City Council and change, so check an address rather than assume. Large parts of Franklinton, the Near East Side, Linden, the Hilltop, Milo-Grogan and the Near South Side sit inside designated areas; higher-value neighborhoods generally do not. The neighborhood list and how to apply are in the roof permit and tax abatement post.

Choosing a contractor in Ohio

Ohio has no statewide residential roofing license. Registration is handled at the county and municipal level, so the checks fall to you:

• Local registration with the building department that will issue your permit
• General liability insurance, with a certificate you verify by calling the carrier yourself
• Workers' compensation — required for employees in Ohio, and without it an injury on your roof becomes your problem
• Manufacturer certification, which is what makes extended system warranties available
• Local references from the last year that you can drive past
• A written contract covering scope, material specifications, the per-sheet decking rate, warranty terms, payment schedule and dates
• No large deposit — a modest amount to schedule and order material is normal; half up front is not

Compare bids on scope before price. If one estimate is thousands under the others, find the line it is missing: reused flashing, ice barrier only at the edge, no ridge vent, no permit, a blank decking rate. And do not sign on a first visit, especially after a hailstorm — a contractor who intends to still be here in five years will give you a day.

What to expect after the work is done

A finished shingle roof should come with an inspection sign-off, a manufacturer warranty on the materials, a workmanship warranty from the installer, registration filed in your name, and a documentation set you keep: invoice, permit, warranty certificates and material list.

For the first few rains, some granule wash-off is normal — loose granules from shipping and installation, not failure. By the second season it should be negligible.

For the first year, look in the attic during heavy rain and after the first hard freeze. Staining, condensation under the deck or ice at the eaves are warranty items, not aging, and easier to resolve while the job is fresh. A properly installed shingle roof in central Ohio gives 25 years or more; where it does not, the cause is nearly always an installation decision.

What to do next

Start with a square count and a pitch, put them into the roof cost estimator, and use the number as the yardstick you hold the bids against. Then get three scoped estimates and compare the lines, not the totals.

If you are weighing systems rather than grades, the metal roof replacement guide covers standing seam and metal shingles with the same cost tables, and the flat roof replacement guide covers the low-slope sections most Columbus houses have somewhere — a porch, a dormer or an addition.
