The roof next door went on last spring, a soft gray you kept admiring from the sidewalk. You asked, and the neighbor’s answer was two words: CertainTeed Landmark. Getting the same roof sounds like one phone call. It nearly is, once you know which Landmark the roofer means, which wind rating the installation will earn, and which warranty that roofer is allowed to register.
Landmark measured by CertainTeed’s data sheet
CertainTeed’s Landmark technical data sheet, dated March 2023, describes a two-piece laminated shingle on a fiberglass mat, with ceramic-coated granules and self-sealing adhesive strips. The key figures:
| Spec | Landmark (2023 data sheet) |
|---|---|
| Size | 13 1/4 x 38 3/4 inches |
| Exposure | 5 5/8 inches |
| Shingles per square | About 66 |
| Weight per square | About 217 to 229 lb, by plant |
| Fire | ASTM E108 and UL 790 Class A |
| Wind tests | ASTM D3161 Class F, ASTM D7158 Class H |
CertainTeed’s product page adds a UL 2218 Class 3 impact rating and the NailTrak feature, which it describes as an extra-wide nailing area for accurate installation.
Landmark, Landmark AR and the related lines
The 2023 sheet covers both Landmark and Landmark AR, the algae-resistant version, and notes that AR shingles are not sold in every region. That sheet gave Landmark AR a 10-year algae warranty. CertainTeed’s current product page lists a 25-year StreakFighter algae warranty instead. The term on your paperwork depends on what is in the bundles. Ask the roofer to confirm the AR label and the algae term in writing.
Landmark also anchors a family. County Roofing Systems in Melville prices Landmark PRO at roughly $75 to $100 a square above standard Landmark. If hail resistance matters more than the Class 3 rating gives you, our impact-resistant shingles guide explains the higher class.
The 110 mph warranty and the upgrade above it
CertainTeed’s product page gives standard Landmark a 15-year, 110 mph wind-resistance warranty and says an upgrade to 160 mph is available. The stated requirement is CertainTeed starter and CertainTeed hip and ridge shingles. The 2023 data sheet names Shadow Ridge, Cedar Crest and Mountain Ridge as the CertainTeed caps for hips and ridges.
Long Island contractors do not always tell the upgrade story the same way. County Roofing’s comparison says Landmark reaches 130 mph with a special starter strip and a six-nail pattern. CertainTeed’s page says 160 mph. When a quote promises a Landmark wind upgrade, ask which speed, which starter and ridge products earn it, and how many nails per shingle the crew will use.
SureStart and the star levels above it
Every Landmark roof carries what CertainTeed calls SureStart protection. The product page puts it at 10 years, and the credentialing page describes it as non-prorated. On top of the lifetime limited, transferable material warranty, CertainTeed offers SureStart PLUS through credentialed contractors who install its Integrity Roof System. Its credentialing page lays out the levels:
- 3-Star. Full coverage up to 50 years including tear-off and disposal, with no workmanship coverage.
- 4-Star. The same, plus 15 years of workmanship coverage.
- 5-Star. The same, plus 30 years of workmanship coverage.
Those 50-year terms apply to single-family detached houses. For 4-Star and 5-Star, CertainTeed limits other structures to 25 years. The page says 3-Star coverage is fully transferable for 15 years and 4-Star and 5-Star for 20. Some contractor and third-party summaries give different workmanship lengths, so check the level named on your contract against CertainTeed’s current page.
Where Landmark meets low slopes and eave ice
Look up at the shallow roof over the porch or the addition before you sign. The data sheet limits Landmark to slopes greater than 2 inches per foot, and slopes from 2:12 up to 4:12 need extra underlayment. Where ice along the eaves can back water up, CertainTeed calls for its WinterGuard waterproofing underlayment or an equivalent. Our ice dams guide covers how they form and what keeps meltwater out.
CertainTeed also says the shingles need no routine maintenance when installed to its instructions. It still recommends an inspection at least once a year, and more often on an older roof.
What Long Island roofers charge for Landmark
In Melville, County Roofing Systems charges between $450 and $600 a square for Landmark with installation, roughly $9,000 to $12,000 across a 20-square roof. It gives Owens Corning Duration the same per-square range. LI Roofing Co. in North Massapequa counts Landmark among the three shingles its crews install most, with GAF Timberline HDZ and Owens Corning Duration. To weigh Landmark against those two, see our GAF vs Owens Corning vs CertainTeed comparison, and for how architectural shingles differ from 3-tab, the asphalt shingle roof page.
Before you sign for Landmark
- Confirm the product name. Landmark, Landmark AR and Landmark PRO are different shingles.
- Check that the starter and ridge caps are CertainTeed products, since the wind upgrade depends on them.
- Ask whether the roofer holds a CertainTeed credential, and which SureStart PLUS level they will register.
- If any section of the roof is low-slope, ask how the extra underlayment is handled.
- For a color match with a neighbor’s roof, look at full shingles, not a printed brochure.
