Asphalt roof replacement service is one of six asphalt shingle roof services, priced from a $150 pipe-boot repair to a full tear-off and reroof at $5 to $8 per square foot installed, the architectural-asphalt range in our 2026 roofing cost report. Most contractor websites lump all six under “roofing services” and leave the homeowner to work out which one the roof needs. Calling a replacement crew for a leak that needed a $600 valley repair wastes thousands, and so does paying for repeat patches on a roof past its service life. The sections below price each service, name the materials involved and give the age-and-failure rule for choosing.
Service 1: full new install or replacement
Full replacement (tear-off plus install) is the largest service category. At the $5 to $8 per square foot architectural-asphalt range from our 2026 roofing cost report, a typical 2,000 to 2,400 square foot roof (20 to 24 roofing squares) lands at about $10,000 to $19,200 installed. Coastal California, the Pacific Northwest and parts of New England run toward the top of that band, and a steep pitch, multiple valleys or a second layer to remove each add labor. Our roof cost per square foot reference covers regional pricing.
Mainstream architectural lines in 2026 are GAF Timberline HDZ, Owens Corning Duration, CertainTeed Landmark, IKO Cambridge, Atlas Pinnacle Pristine, Tamko Heritage and Malarkey Vista (a polymer-modified asphalt line). The warranty terms differ in ways that matter. Owens Corning lists Duration wind resistance at 160 mph when its component requirements are met and starter shingles are installed on both eaves and rakes, with 25 years of algae resistance. CertainTeed lists Landmark with a 15-year, 110 mph wind-resistance warranty, upgradeable to 160 mph, plus 10-year SureStart protection. Atlas markets Pinnacle Pristine with a Scotchgard Protector algae coating. Our brand reviews cover the rest: GAF Timberline HDZ review, Owens Corning Duration review, CertainTeed Landmark review and Atlas Pinnacle Pristine review.
A proper full replacement includes tear-off of all existing layers down to the deck, deck inspection and replacement of any rotted plywood or OSB (typically billed at $75 to $125 per sheet of replacement), drip edge install on all eaves and rakes (IRC R905.2.8.5), ice and water shield in valleys and along eaves in cold-climate regions (to 24 inches inside the exterior wall line where IRC R905.1.2 requires an ice barrier), synthetic underlayment across the field, starter strip along all eaves and rakes, the field shingles, ridge cap shingles, and replacement of all penetration flashings (pipe boots, step flashing at sidewalls, apron flashing at chimneys, vent boots). Anything skipped on this list is corner-cutting; see shingle roofing services for the contractor side.
Service 2: partial replacement
Partial replacement (sometimes called a “section replacement”) swaps out one slope or one section of the roof while leaving the rest in place. Cost typically runs $2,500 to $8,000 depending on the section size. The work is most common when one slope took a hit (large branch impact, localized hail damage on one face) while the rest of the roof remains serviceable.
The catch with partial replacement is that the new shingles will not match the weathered shingles next to them. The granule color, the surface texture, and the visual depth all change over the first 24 to 36 months in service. A partial replacement done in 2026 next to a 9-year-old section will be visibly different for the first two to three years and then blend in as the new shingles weather. Some homeowners do not mind. Some do.
The other catch is insurance. Matching rules vary by carrier and state, and if the maker has discontinued your color, a claim may pay for the affected slope only, leaving a visible mismatch you cannot resolve. This is one of the cases where a 30 point roof inspection from an independent inspector helps you negotiate a full replacement payout instead.
Service 3: repair (the high-frequency, low-dollar category)
Repair is the highest-volume service category and the one where contractors make consistent margin. Sub-categories with typical 2026 pricing:
Single shingle replacement: $150 to $350 per visit. Lifting and re-securing a few wind-blown shingles on a recent roof falls in this band. A real fix matches the existing brand and color, or comes close enough that the patch is not obvious from the street; brand-by-brand specs are in our 2026 Shingle Brand Comparison Report.
Pipe boot or vent boot replacement: $150 to $450 installed. Boots are the EPDM or rubber-and-aluminum collars around plumbing vent stacks. They fail before the shingles do, typically at year 8 to 12, and they are the single most common source of slow leaks. We covered the signs in our how to fix a roof leak guide.
Valley repair: $600 to $2,200 depending on length and whether it is a closed-cut valley or a W-valley with metal. Valleys are the second most common leak point after flashings.
Patch repair (single small section, removing and replacing a handful of shingles around a leak): $200 to $500. The repair tech opens up the suspect area, finds the source (almost always a flashing or fastener), corrects it, and replaces the shingles. A real patch is invisible from below and dry from above.
Chimney flashing rebuild: $700 to $2,800 depending on chimney width and whether the existing flashing was step + counter (correct) or surface-mounted L-flashing with caulk (wrong, common, leaks). We walk through the right chimney flashing approach in our chimney flashing leak repair deep dive.
Sagging deck or rafter repair: $1,200 to $5,500 depending on the cause. A sagging line on the roof from below usually points to a structural problem (rotted decking, broken rafter, water-damaged truss chord). The fix is structural before any shingle work. We cover the diagnostic and repair path in our sagging roof repair guide.
Service 4: inspection
A real roof inspection takes 45 to 90 minutes and produces a written report with photos. Cost ranges from “free” (sales-driven inspection from a contractor angling for a replacement contract, often after a storm) to $650 (independent third-party inspector with no skin in the work). The middle of the market, $150 to $400, is a paid inspection by a small contractor or a roofing-specialized home inspector. The paid inspection is almost always worth the money if you are buying a home, selling a home, filing an insurance claim, or trying to decide between repair and replacement on an aging roof.
The free inspection is a sales call, so test the report: a useful one lists each defect with a photo, the slope it is on and a measurement (for example, the number of lifted tabs on the south slope), while a one-page recommendation for full replacement with no supporting detail is a pitch. We documented the warning signs in our roofing scams reference.
Service 5: maintenance plans
Maintenance plans are a newer service offering. The typical plan: annual visit, debris removal, fastener check, flashing seal check, gutter clearing, minor repairs included up to a stated dollar value, written report. Cost typically $250 to $650 per year. Some plans include a 10 percent discount on any repair work outside the included scope.
For an asphalt shingle roof past year 10, a $250 to $650 annual plan pays off because it catches small problems (lifted shingles, dried boots, loose flashings) before they become large problems (active leaks, decking damage, ceiling stains). For a roof in years 1 through 5, the maintenance plan is mostly a profit center for the contractor because the warranty covers almost everything the plan would address. We sized the maintenance economics in our annual roof tune up cost analysis.
Service 6: overlay or “lay-over”
Overlay means installing a second layer of shingles directly on top of the existing layer without tearing off. It costs less than a tear-off because demolition and disposal labor goes away. The catch is real: IRC R908.3.1.1 does not allow a roof recover where the existing roof already has two or more layers, so an overlay is a one-time option, and many jurisdictions restrict it further. The added weight can stress older framing, the new shingles cannot lie flat over the old texture, and a later replacement must tear off both layers at higher cost.
If a contractor is pushing overlay as the primary option, ask for the layer count, the framing check and the code section they are relying on in writing.
How to tell which service you actually need
Three diagnostic questions. First, how old is the roof. If it is under year 12, repair is almost always the right call unless storm damage exceeded 25 percent of the surface area. If it is between year 12 and year 18, repair is still typically right unless multiple issues are stacked or the shingles are visibly granule-stripped. If it is year 18 to 24, evaluate replacement carefully and weigh the repair cost against the remaining service life. If it is over year 24, replacement is usually the better long-term economics even if no active leaks exist. We covered the timing question in our signs you need a new roof guide.
Second, what is the failure pattern. Isolated failures (one boot, one valley, one wind-lifted section) point to repair. Distributed failures (multiple spots, multiple slopes, multiple flashing types) point to replacement. Granule loss across the field of the roof points to replacement.
Third, what does the insurance claim look like. If a storm caused the damage, an insurance carrier’s adjuster will inspect and assign either a partial payment or a full replacement allowance. The carrier’s call (and the policy’s language on matching, actual cash value vs. replacement cost value, and depreciation recovery) shapes which service is economically right for you.
If X, then Y: repair or replace by roof age
| If your roof is | Then |
|---|---|
| Under 12 years old | Repair, unless storm damage exceeded 25 percent of the surface area |
| 12 to 18 years old | Repair, unless multiple issues are stacked or the shingles are visibly granule-stripped |
| 18 to 24 years old | Weigh the repair quote against the remaining service life before deciding |
| Over 24 years old | Replace; the long-term economics usually beat repair even with no active leak |
| Failures on multiple slopes or granule loss across the field | Replace |
| One boot, one valley or one wind-lifted section | Repair |
What goes into a quote you can compare
A real asphalt shingle service quote names the work clearly. For full replacement: tear-off layers (state how many), deck inspection, decking replacement allowance (state per-sheet rate and assumed sheet count), drip edge brand and color, underlayment brand (the recommended options are in our best synthetic underlayment brands review), ice and water shield brand and coverage, starter strip brand and length, field shingle brand and color and warranty tier, ridge cap brand, all flashing replacements with materials specified, ventilation upgrades, debris haul-off and dump fees, manufacturer warranty registration. For repair: scope of work in writing, materials matching the existing roof, leak warranty period on the repair (12 months is standard, 24 months is excellent).
A vague quote (“furnish and install asphalt shingles, complete”) leaves the contractor room to substitute and the homeowner with no recourse. A clear quote with named brands and itemized line items is the price you can hold them to. We built sample contracts in our roofing contract template and quote-grading approach in our roofing estimate template.
The contractor selection question
All six service categories above (install, partial, repair, inspection, maintenance, overlay) can be handled by the same contractor or by different contractors. Most homeowners benefit from selecting one contractor for replacement and a separate repair specialist for ongoing service. Replacement contractors live on volume and high-margin jobs. Repair specialists live on speed and accuracy. The skill sets overlap but they are not the same.
The contractor selection criteria we walk through in how to choose a roofing contractor apply to all asphalt shingle services. Licensed, insured (general liability and workers’ comp), in the local market more than 5 years, willing to put material brands and warranty registration in writing, and willing to share three local references on jobs older than 3 years. Stack the criteria. Skip any contractor who hedges on any of them.
Final read
Asphalt shingle roof services are not one product. They are six. The right one for your roof depends on age, failure pattern, claim status, and budget. The right contractor matches the service. The right quote names every material and every line item. The right outcome is a roof and a contract you do not need to second-guess. Match the service to the actual need, vet the contractor on what they put in writing, and the rest of the decision becomes mostly arithmetic.
