CertainTeed Landmark shingles are the company’s flagship architectural line, priced at $30 to $45 per bundle in 2026. The certainteed landmark family includes Landmark Standard, Landmark Pro, Landmark Premium, and Landmark IR (impact-resistant), giving CertainTeed the deepest architectural lineup of the big-three manufacturers. Here is how each tier compares, where the line wins and loses against GAF and Owens Corning, and which Landmark SKU actually makes sense for your roof.
This is an independent review. We have spent the last six months reading installer feedback, pulling spec sheets, comparing warranty fine print, and tracking regional pricing. Our verdict is in section one. The fine print runs through 18 sections plus FAQs.
The short version
- The Landmark line has four tiers: Standard ($30 to $36), Pro ($34 to $40), Premium ($38 to $44), and IR ($40 to $45). Installed cost ranges from $450 to $700 per square depending on tier and region.
- Landmark Pro is the volume seller and the value pick for most US homeowners. It carries a 15-year StreakFighter algae warranty, which is the strongest in the big-three.
- Wind rating is 110 mph standard, 130 mph with the SureStart PLUS warranty extension. Class 3 impact under UL 2218, with Class 4 on the Landmark IR variant.
- Landmark is heavier per square than GAF Timberline HDZ or OC Duration, which contributes to a stronger visual shadow line and slightly better wind performance through mass alone.
- ClimateFlex (SBS-modified) is the cold-weather story. Standard Landmark seals reliably down to about 45 degrees F; Landmark IR with ClimateFlex performs better at lower temperatures.
- Best for: humid-climate homeowners who want the longest mainstream algae warranty, and hail-belt residents who can step up to Landmark IR for Class 4 plus insurance discount. Not for: anyone whose primary criterion is the strongest wind rating, where Duration STORM at 150 mph is the better SKU.
The short answer: four Landmark tiers and pricing
CertainTeed structures the Landmark line as a four-tier hierarchy. Most homeowners end up choosing between Landmark Pro (the volume seller) and Landmark IR (the hail-belt upgrade). Landmark Standard is a value tier that exists primarily in builder-grade and rental property installations. Landmark Premium is a heavier shingle aimed at premium residential renovations where shadow-line depth and visual presence matter.
| Tier | Per bundle pricing | Weight per square | Wind warranty | Impact rating | Algae warranty |
|---|---|---|---|---|---|
| Landmark Standard | $30 to $36 | ~240 lbs | 110 mph (130 with SureStart PLUS) | Class 3 | 15 yrs (StreakFighter) |
| Landmark Pro | $34 to $40 | ~270 lbs | 110 mph (130 with SureStart PLUS) | Class 3 | 15 yrs (StreakFighter) |
| Landmark Premium | $38 to $44 | ~300 lbs | 110 mph (130 with SureStart PLUS) | Class 3 | 15 yrs (StreakFighter) |
| Landmark IR | $40 to $45 | ~275 lbs | 110 mph (130 with SureStart PLUS) | Class 4 | 15 yrs (StreakFighter) |
The price spread from Standard to IR is roughly $300 to $500 across a typical 22 to 30 square roof. That spread is the lever that matters. The right pick is rarely Premium. The interesting comparison is Standard versus Pro for budget-conscious buyers, and Pro versus IR for hail-belt residents.
Landmark Standard: entry-level architectural
Landmark Standard is the four-tab dimensional shingle at the entry of the line. Weight is about 240 pounds per square, which is competitive with GAF Timberline HDZ (240 lbs) and a touch heavier than OC Duration Standard (230 lbs).
The shingle uses standard asphalt (not SBS-modified). The granule color blend is the same as Pro, giving it the same visual identity from ground level. The differences between Standard and Pro are not visible to the homeowner; they are structural.
Where Standard makes sense: rental properties, builder-spec installations, garage and outbuilding roofs, and detached structures where a full Pro premium does not pencil. Where Standard does not make sense: primary residence renovations where the $4 to $6 per bundle delta to Pro is small money over a 25-year horizon.
Landmark Pro: the mid-tier and the volume seller
Landmark Pro is the most-installed Landmark SKU and the right pick for most US homeowners. The weight bump to ~270 pounds per square is meaningful. The extra mass contributes to:
- Stronger shadow lines. Thicker laminate creates deeper visual definition, the look most homeowners actually want when they upgrade from a 3-tab shingle.
- Better wind performance through mass. Heavier shingles resist initial wind uplift better than lighter alternatives, independent of nailing technology.
- Improved walkability during install and post-install repair. Heavier laminate is less prone to scuffing under foot traffic from HVAC or solar work.
Pro uses the same standard (non-SBS) asphalt as Standard. The SBS-modified upgrade is only on Landmark IR and Landmark Solaris. If you want cold-weather flexibility in a non-IR product, Pro is not the SKU; that requirement points to the IR variant or to OC Duration FLEX.
Landmark Premium: higher TG-points, premium price
Landmark Premium adds another mass increment (~300 lbs per square) and a slightly deeper shadow profile. The economic case for Premium over Pro is narrow. The extra $4 to $6 per bundle ($300 to $500 across a roof) buys visual presence rather than functional performance. Wind rating, impact rating, algae warranty, and color palette are unchanged from Pro.
Where Premium makes sense: high-end residential renovations where the roof is a visible architectural element (steep pitches, prominent street-facing facades, custom homes with slate or wood-shake aesthetic goals). Where Premium does not make sense: standard suburban tract roofs where ground-level visual difference from Pro is minimal.
Landmark IR: Class 4 impact for hail-belt states
Landmark IR is the impact-resistant SKU. It uses SBS-modified (rubberized) asphalt that provides Class 4 impact resistance under UL 2218 while also delivering improved cold-weather flexibility.
The economic case in hail-belt states is strong. Insurance premium discounts on Class 4 roofs:
| Carrier | Typical discount range | Strongest states |
|---|---|---|
| State Farm | 10 to 25 percent | TX, OK, KS, CO |
| Allstate | 5 to 20 percent | TX, OK, KS, NE |
| Travelers | 15 to 30 percent | TX, OK, KS |
| USAA | 15 to 30 percent | TX, OK, CO, KS |
In Texas, where average wind-and-hail premiums run $2,400 to $3,800 annually, a 20 percent discount recovers the IR upgrade premium in 3 to 5 years. For homeowners staying 7 plus years, this is a clear positive expected value. Verify the discount with your specific carrier before installation, because policy terms vary.
Pricing comparison across the 4 tiers
| Region | Standard | Pro | Premium | IR |
|---|---|---|---|---|
| Southeast | $30 to $34 | $34 to $38 | $38 to $42 | $40 to $44 |
| Texas | $30 to $34 | $34 to $38 | $38 to $42 | $40 to $45 |
| Midwest | $32 to $36 | $36 to $40 | $40 to $44 | $42 to $45 |
| Northeast | $34 to $36 | $38 to $40 | $42 to $44 | $44 to $45 |
| Mountain West | $32 to $36 | $36 to $40 | $40 to $44 | $42 to $45 |
| Pacific | $34 to $36 | $38 to $40 | $42 to $44 | $44 to $45 |
Installed cost lands at $450 to $675 per square for Standard, $500 to $700 for Pro, $550 to $725 for Premium, and $575 to $725 for IR. For a 22 to 30 square roof, total installed cost ranges from $11,000 to $22,000 across the line. Our broader breakdown is at /how-much-does-a-new-roof-cost/.
Wind rating: 110 to 130 mph under ASTM D7158
Standard Landmark wind warranty is 110 mph. With SureStart PLUS warranty extension (requires CertainTeed integrated system installation), the wind warranty extends to 130 mph. This is lower than GAF Timberline HDZ (130 mph standard) or OC Duration (130 mph standard) at the entry warranty level.
The wind warranty distinction matters less than the rating itself. Landmark Pro tests well in independent wind events, and the heavier mass per square contributes to real-world wind performance that often exceeds the 110 mph warranty number. The warranty is conservative. The product behaves better than the label.
For high-wind coastal applications (sustained design wind speeds above 130 mph: South Florida HVHZ zones, coastal Texas, parts of North Carolina), neither standard Landmark nor SureStart PLUS gets you to the right rating. The right SKU for these zones is a non-Landmark product or a Landmark IR with site-specific engineering.
Impact rating: Class 3 standard, Class 4 on IR
Landmark Standard, Pro, and Premium are all Class 3 under UL 2218. Landmark IR is Class 4. The Class 4 differentiation is the entire value proposition of the IR SKU. If you do not need Class 4 (and you do not, outside hail-belt and severe-storm zones), Pro is the right pick.
One installer note. Landmark IR’s SBS-modified asphalt is slightly stickier in warm weather, which can make handling during install more challenging on hot days. Crews experienced with the product handle it cleanly; new crews report higher rates of granule disturbance on hot-weather installs.
ClimateFlex technology: the cold-weather story
ClimateFlex is CertainTeed’s SBS-modified asphalt formulation. It is present in Landmark IR and several CertainTeed accessory products (cap shingles, valley material). The benefits in cold-weather installation:
- Improved flexibility at low temperatures. Standard asphalt becomes brittle below about 25 degrees F. ClimateFlex remains flexible at sub-freezing temperatures, reducing crack risk during shoulder-season install.
- Better thermal cycling tolerance. Freeze-thaw cycles in northern climates stress shingles. SBS modification reduces fatigue crack propagation over decades.
- Cold-weather sealing. ClimateFlex seals at lower ambient temperatures than standard asphalt, though all asphalt shingles benefit from some warmth for the self-seal strip to fully bond.
The product gap in the Landmark lineup: there is no ClimateFlex variant in Landmark Pro. If you want SBS modification without Class 4 impact, you have to step into Landmark IR (which adds the impact rating you may not need) or look at OC Duration FLEX. This is a real consumer-choice gap in the CertainTeed line.
Warranty breakdown: Lifetime Limited explained
| Coverage period | What is covered | How payouts work |
|---|---|---|
| Years 1 to 10 (SureStart period) | Full material plus tear-off and disposal labor | Non-prorated |
| Years 11 to lifetime | Material only, prorated | Depreciation schedule |
| Algae (StreakFighter) | 15 years | Material only, prorated after year 1 |
| Wind (standard) | 15 years at 110 mph | Material plus labor first 10 years, material only after |
| Wind (SureStart PLUS upgrade) | 15 years at 130 mph | Requires integrated system installation |
| 4-Star Extended (SELECT ShingleMaster) | 50 years material plus 25 years workmanship | Full coverage if conditions met |
The SureStart period (first 10 years non-prorated) is the same structural concept as GAF’s Smart Choice and OC’s TruPROtection. After year 10, the warranty depreciates aggressively. By year 25, the material payout is a small fraction of replacement cost. This is the category convention; do not penalize CertainTeed specifically for it.
SureStart vs SureStart PLUS warranty extensions
SureStart is the baseline 110 mph wind warranty for 15 years. SureStart PLUS is the upgrade extension that does three things:
- Raises the wind warranty from 110 mph to 130 mph
- Extends the non-prorated period in certain configurations
- Requires installation of CertainTeed integrated roofing system components (CertainTeed underlayment, CertainTeed starter strip, CertainTeed hip and ridge, CertainTeed ventilation)
The economic logic: if you are paying for Landmark Pro or Premium, the marginal cost to add the CertainTeed accessory bundle is small (a few hundred dollars across a roof) and the 130 mph wind warranty is worth the upgrade. Most CertainTeed-Certified installers default to this configuration unless the homeowner explicitly opts out.
The 4-Star Extended warranty (also called Integrity Roof System warranty) is the strongest CertainTeed warranty. It requires SELECT ShingleMaster contractor installation. SELECT ShingleMasters are the top tier in the CertainTeed installer network, comparable to GAF Master Elite and OC Platinum Preferred.
Color options: 29 plus across the line
The Landmark color palette runs 29-plus colors across the four tiers. Common stocked colors at most US supply yards:
| Color family | Common stocked | Regional or special order |
|---|---|---|
| Grays and blacks | Moire Black, Charcoal Black, Driftwood, Pewter, Silver Birch | Cobblestone Gray, Atlantic Blue, Heather Blend |
| Browns | Weathered Wood, Burnt Sienna, Resawn Shake, Heather Blend, Hickory Blend | Mountain Timber, Maximum Russet, Color Blend Heather |
| Greens and accent | Hunter Green | Georgetown Gray, Birchwood, Terra Cotta |
Some Landmark colors carry CRRC-rated solar reflectance values that qualify for cool-roof codes (Title 24 in California) and utility rebates. Silver Birch and Pewter are common cool-roof qualifying colors. If energy compliance or rebates matter, check the specific CRRC rating for your color on coolroofs.org before signing.
Landmark vs GAF Timberline HDZ
| Spec | CertainTeed Landmark Pro | GAF Timberline HDZ |
|---|---|---|
| Wind rating (standard) | 110 mph (130 with SureStart PLUS) | 130 mph |
| Wind rating (premium) | 130 mph with integrated system | No max with WindProven |
| Impact rating (standard) | Class 3 (Class 4 on Landmark IR) | Class 3 |
| Algae warranty | 15 years (StreakFighter) | 10 years (StainGuard Plus) |
| Weight per square | ~270 lbs (Pro) | ~240 lbs |
| Color options | 29 plus | 24 plus |
| Per bundle pricing (mid-tier) | $34 to $40 (Pro) | $35 to $50 |
| Top installer scarcity | ~3% (SELECT ShingleMaster) | ~2% (Master Elite) |
Landmark Pro wins on algae warranty (15 versus 10 years), weight (a real factor in wind and visual presence), color depth, and entry price. HDZ wins on standard wind rating (130 versus 110 mph at the entry warranty level). The choice frequently comes down to which contractor network is stronger in your zip code, and whether algae resistance or wind rating is the higher local concern. Our full HDZ analysis is at /gaf-timberline-hdz-review/.
Landmark vs Owens Corning Duration
| Spec | CertainTeed Landmark Pro | OC TruDefinition Duration |
|---|---|---|
| Wind rating | 110 to 130 mph | 130 mph (150 on STORM) |
| Impact rating | Class 3 (Class 4 on IR) | Class 3 (Class 4 on STORM) |
| Algae warranty | 15 years | 10 years |
| Nailing technology | Conventional nailing strip | SureNail (woven fabric reinforcement) |
| Weight per square | ~270 lbs | ~230 lbs |
| Color options | 29 plus | 28 plus |
| Per bundle pricing | $34 to $40 (Pro) | $32 to $48 |
Landmark wins on algae warranty and weight. Duration wins on nailing technology (SureNail is a meaningful engineering reinforcement that Landmark does not have an equivalent of) and on standard wind rating without requiring a warranty upgrade. The cold-weather story slightly favors Duration via the FLEX SKU, which has no clean Landmark equivalent below the IR tier. Our full Duration review is at /owens-corning-duration-shingles-review/.
CertainTeed SELECT ShingleMaster requirement
SELECT ShingleMaster is the top of the CertainTeed contractor network, comparable in scarcity to GAF Master Elite and OC Platinum Preferred. Roughly 3 percent of US roofing contractors hold this certification, which makes it slightly more accessible than the competitor top tiers.
SELECT ShingleMasters can offer the 4-Star Extended warranty (50 years material plus 25 years workmanship), which is the strongest CertainTeed warranty. If you are paying for Landmark Pro, Premium, or IR and your installer is not SELECT ShingleMaster, you are leaving warranty value on the table. For contractor vetting guidance, see /how-to-choose-a-roofing-contractor/.
The CertainTeed installer hierarchy:
- CertainTeed Credentialed. Basic agreement, training completion.
- CertainTeed Quality Master. Demonstrated quality track record.
- CertainTeed SELECT ShingleMaster. Top tier. 5 plus years experience, ongoing training, customer satisfaction screening, financial stability.
The Integrity Roof System: components and accessory math
CertainTeed packages Landmark as part of the Integrity Roof System, the company’s branded integrated installation package. The system includes specific CertainTeed components at each layer. The 4-Star Extended warranty (the strongest CertainTeed warranty) requires the full Integrity Roof System installed by a SELECT ShingleMaster.
- Underlayment. RoofRunner (synthetic) is the volume seller. DiamondDeck is the premium synthetic. Both outperform 15 lb felt in tear resistance and walkability.
- Ice and water shield. WinterGuard is the standard CertainTeed product. Required at eaves and valleys in northern climates per code. Often the highest-impact upgrade in cold climates.
- Starter strip. SwiftStart from CertainTeed is the volume starter. Factory-cut starters seal more reliably than field-cut starter from cap shingles.
- Hip and ridge. Mountain Ridge or Cedar Crest, depending on visual aesthetic. Mountain Ridge has a deeper visual profile that matches Landmark Pro and Premium well.
- Ventilation. CertainTeed Ridge Vent products integrate with the system. As discussed throughout this review series, attic ventilation is the under-recognized roof-life factor. Proper NFA calculation is non-negotiable.
The full Integrity Roof System bundle adds roughly $400 to $900 to the cost of a typical roof beyond Landmark shingle material. For 4-Star Extended warranty eligibility, the bundle is required. For SureStart PLUS warranty, the bundle is also required (this is how the 130 mph wind upgrade is achieved on the warranty side).
Real installer feedback: alignment and nail-line considerations
We pulled three months of contractor commentary from NRCA forums, RoofingTalk, and the CertainTeed SELECT ShingleMaster community.
What installers like. The heavier Pro and Premium variants are easier to align cleanly because the laminate has more visual edge definition. Color consistency across pallets is good. The 15-year algae warranty closes deals with humid-climate homeowners more easily than competitor 10-year warranties. CertainTeed’s regional supply network is dense; same-day or next-day color availability is usually achievable.
The alignment consideration. Landmark’s reveal alignment is sensitive to course straightness. Crews who chalk and snap lines on every third course produce excellent results. Crews who eye-ball alignment occasionally produce roofs with subtle wave patterns that catch the light unfavorably from certain angles. This is a contractor-quality variable more than a product issue, but Landmark is less forgiving than GAF HDZ for sloppy alignment.
Nail-line visibility. Heavier shingles with deeper shadow lines (Landmark Premium especially) can show nail-line telegraphing if nails are driven slightly proud. This is true of all premium architectural shingles. Installers who set nail-gun pressure correctly avoid the issue. Hand-nailing virtually eliminates it.
Cold-weather sealing. Landmark Standard and Pro behave like other non-SBS asphalt shingles. They seal reliably above 50 degrees F and benefit from hand-sealing assistance below. Landmark IR with ClimateFlex performs better at lower temperatures.
Landmark IR economics: the worked Class 4 case
The Landmark IR upgrade decision deserves the same worked-numbers treatment as Duration STORM. Example using mid-range numbers from a 25-square roof in Oklahoma City:
| Line item | Landmark Pro | Landmark IR | Delta |
|---|---|---|---|
| Per bundle | $37 | $43 | +$6 |
| Per square (3 bundles) | $111 | $129 | +$18 |
| Total material (25 sq) | $2,775 | $3,225 | +$450 |
| Installed total | $14,000 | $15,500 | +$1,500 |
| Wind-and-hail premium baseline | $3,200/yr | $3,200/yr | — |
| Class 4 discount (25% typical for OK) | $0 | $800/yr | -$800/yr |
| Years to recover upgrade premium | — | 1.9 years | — |
For Oklahoma residents specifically, the recovery period is under 2 years. For Texas, Kansas, and Colorado, 2 to 4 years is typical. For homeowners staying 5 plus years, IR is the right choice. Verify the discount magnitude with your specific carrier before signing; not all carriers offer the same Class 4 reduction, and some require third-party certification documentation.
Where Landmark falls short
Standard wind rating is 110 mph, the lowest of the big-three flagship lines. This is offset by SureStart PLUS extension to 130 mph, but the marketing position is weaker.
No SBS-modified option below the IR tier. Cold-climate buyers who do not need Class 4 impact have a real product gap in the Landmark line. OC Duration FLEX fills this gap better.
Premium is hard to justify economically. The Premium tier exists primarily for high-end aesthetic upgrades. Most homeowners should stop at Pro or step directly to IR.
SELECT ShingleMaster availability varies by market. Coverage is good in major metros but thin in some rural areas, putting the 4-Star Extended warranty out of reach for some buyers.
Lifetime warranty prorates aggressively after year 10. Same structural pattern as competitors. The “Lifetime” label is depreciation-schedule fine print.
Reading a Landmark quote: what each line item should look like
A reasonable Landmark Pro quote from a SELECT ShingleMaster in a mid-cost US market for a 25-square roof should resemble the breakdown below. If your quote is dramatically different in proportion, the questions are why.
| Line item | Typical share of total | Notes |
|---|---|---|
| Tear-off and disposal of existing roof | 10 to 15 percent | Higher for multiple existing layers |
| Decking inspection and replacement allowance | 3 to 8 percent | Quoted as allowance with overage billing |
| Underlayment (synthetic) plus WinterGuard | 5 to 8 percent | Required in northern climates per code |
| Landmark Pro shingles | 18 to 28 percent | Higher proportion on smaller roofs |
| Integrity Roof System accessories | 5 to 10 percent | SwiftStart, Mountain Ridge, drip edge, flashing |
| Ridge ventilation upgrades | 2 to 5 percent | Critical for warranty and roof life |
| Labor (install, supervision) | 30 to 40 percent | Largest single bucket |
| Warranty registration and overhead | 3 to 6 percent | Contractor margin and admin |
Two flags. First, if the accessory bundle is bundled into a vague “system” line, you cannot verify 4-Star Extended warranty eligibility. Demand itemization. Second, if a contractor offers Landmark Standard pricing but is using Landmark Pro material, that is good for you, but it might also indicate a contractor who is not careful about specification matching, which affects warranty filings later.
Best for, not for: the decision framework
Best for:
- Humid-climate homeowners (Gulf Coast, southeast, Pacific Northwest) where the 15-year StreakFighter algae warranty is a meaningful upgrade over 10-year competitor warranties
- Hail-belt residents who can step up to Landmark IR for Class 4 plus insurance discount
- Homeowners who want a heavier shingle with deeper shadow lines (Pro or Premium) for visual presence
- Markets with strong CertainTeed SELECT ShingleMaster contractor coverage
- Buyers in the southeast where CertainTeed’s manufacturing and distribution density is strongest
Not for:
- Buyers prioritizing the strongest standard wind rating (Duration at 130 mph and HDZ at 130 mph beat Landmark’s 110 mph baseline)
- Cold-climate homeowners who do not need Class 4 impact and want SBS modification (OC Duration FLEX is the cleaner pick)
- Markets where SELECT ShingleMaster contractor coverage is thin and the 4-Star Extended warranty is unreachable
- Buyers shopping the cheapest path to a flagship shingle (GAF Natural Shadow or OC Oakridge are the value tiers, not Landmark Standard)

FAQs
Is CertainTeed Landmark better than GAF Timberline HDZ?
Better is feature-dependent. Landmark Pro has a stronger algae warranty (15 years versus 10), heavier weight per square, and slightly deeper color palette. HDZ has a stronger standard wind rating (130 mph versus 110 mph) and a more accessible top-tier installer network. The choice frequently comes down to which contractor network is stronger in your zip code, and whether algae resistance or wind rating is the higher local priority.
How long does CertainTeed Landmark Pro last?
Realistic service life is 22 to 30 years in moderate climates with proper installation and attic ventilation. Hot-climate installations commonly see 20 to 25 years. Cold-climate installs with good ventilation can reach the upper end. The “Lifetime” warranty label refers to a prorated depreciation schedule, not service expectation. See /asphalt-shingle-roof-lifespan/ for full breakdown.
What is the difference between Landmark Standard, Pro, Premium, and IR?
Standard is the entry weight (~240 lbs per square) at the lowest price point. Pro adds mass (~270 lbs) and stronger shadow lines, same wind and impact specs. Premium adds more mass (~300 lbs) for visual presence, same functional specs. IR uses SBS-modified asphalt for Class 4 impact resistance and cold-weather flexibility. The IR is the only Class 4 SKU in the line.
Do I need a SELECT ShingleMaster contractor?
You need SELECT ShingleMaster to qualify for the 4-Star Extended warranty (50 years material plus 25 years workmanship). The standard Lifetime Limited warranty is available with any qualified CertainTeed-Credentialed installer. SELECT ShingleMaster certification is held by roughly 3 percent of US roofing contractors.
Is Landmark IR worth the upgrade premium?
In hail-belt states (TX, OK, KS, NE, CO, the Dakotas), almost always. The Class 4 rating typically qualifies for 10 to 30 percent insurance premium reduction, which recovers the upgrade cost in 3 to 5 years. Outside hail-belt zones, IR is over-spec for most homeowners and Pro is the right pick.
What does StreakFighter actually do?
StreakFighter is the copper-containing granule system that suppresses Gloeocapsa magma algae growth. CertainTeed warrants visible algae streaking against the shingle surface for 15 years from installation. This is the strongest mainstream algae warranty among GAF, Owens Corning, and CertainTeed. Atlas Pinnacle Pristine extends further at 25 years.
Can I install Landmark in winter?
You can install Landmark Standard and Pro in winter, but the self-seal strip will not bond until temperatures rise above about 50 degrees F. Hand-sealing each shingle with roof cement is the standard cold-weather mitigation. Landmark IR with ClimateFlex performs better at lower temperatures and is the right choice for shoulder-season installs in northern climates.
Is the CertainTeed warranty transferable?
Yes, once. The transfer must happen within the first 20 years of installation. The new owner’s coverage converts to a fixed-term warranty rather than continuing as Lifetime. The 4-Star Extended warranty has slightly different transfer terms; read the specific warranty document for your install year.
