IKO Cambridge vs CertainTeed Landmark in Vancouver: Real-World Differences That Matter

Why These Two Shingle Lines Get Compared in Vancouver

Why These Two Shingle Lines Get Compared in Vancouver

IKO Cambridge and CertainTeed Landmark are compared so often in Vancouver because they sit in the same real-world decision tier for homeowners. Both are architectural (laminate) asphalt shingles, and both are commonly positioned as the step up from basic 3-tab shingles during a roof replacement.

Across Metro Vancouver, these two products dominate residential reroofs—especially on detached homes, duplexes, and townhouses built from the 1980s onward. They’re widely available, competitively priced, and familiar to most roofing crews. When homeowners ask for “a better shingle without going premium,” these are usually the two names that surface first.

The comparison matters more here than in drier climates because Vancouver stresses roofs differently. Persistent rain, shaded roof planes, moss growth, and frequent wind events expose weaknesses faster. A shingle that performs fine in theory can behave very differently after five to ten wet winters.

Homeowners often assume these products are interchangeable. On paper, they look similar. In practice, subtle differences in design, weight, granule behavior, and installation tolerance can matter—especially once local conditions start taking their toll.

Core Design & Material Differences

Core Design & Material Differences

At a glance, both Cambridge and Landmark are laminated shingles designed to add thickness, shadow lines, and depth compared to flat 3-tabs. But their visual character and construction philosophy differ.

IKO Cambridge uses a multi-layer laminate approach with a slightly more matte, textured appearance. The color blends tend to be softer and more muted, which often pairs well with Vancouver’s cedar-heavy streetscapes and older neighbourhoods. On craftsman homes or traditional west coast styles, Cambridge shingles tend to read as understated rather than bold.

CertainTeed Landmark leans into a more dimensional, high-contrast look. Their layering creates sharper shadow lines, and the color palettes often have stronger contrast between granule tones. This can enhance curb appeal on newer builds, west coast modern homes, or properties where homeowners want the roof to visually “pop.”

From a material standpoint, Landmark shingles are typically heavier per square than Cambridge. That extra weight comes from thicker layering and denser granule application. In theory, this contributes to durability and wind resistance. In practice, it also affects handling, fastening, and how the shingle behaves once installed.

Granule coverage also differs. Landmark shingles tend to have a more aggressive granule load, which enhances UV protection but can influence how they shed water and debris over time. Cambridge granules are slightly finer and more uniform, which changes how moss and dirt accumulate in shaded areas.

Aesthetics aren’t just cosmetic here—they influence drying behavior, heat absorption, and how quickly organic growth takes hold on north-facing slopes.

Performance in Rain, Wind & UV — What You Actually See

Performance in Rain, Wind & UV — What You Actually See

In real Vancouver conditions, performance differences show up gradually, not dramatically.

Wind uplift is often cited in manufacturer literature, but field performance depends heavily on installation quality. That said, Landmark shingles generally feel stiffer and more rigid, which can help resist edge flutter in exposed areas. Cambridge shingles are slightly more flexible, which can be beneficial on complex rooflines but may show more movement on high-wind slopes if nailing is inconsistent.

Rain exposure is where granule adhesion becomes noticeable over time. In long wet seasons, shingles don’t get many full dry-out cycles. Landmark’s heavier granule load tends to hold up well initially, but when granules do release, the contrast can be more visible. Cambridge shingles may show more uniform aging, with less dramatic patchiness—but potentially earlier softening in high-exposure zones.

UV resistance and color fade also behave differently. In Vancouver, UV damage is less about scorching sun and more about long-term exposure without drying. Landmark colors tend to hold contrast longer on sunny south-facing slopes. Cambridge colors often fade more evenly, which some homeowners prefer aesthetically.

Moss and algae resistance is heavily influenced by shade, ventilation, and maintenance—but granule texture plays a role. In shaded, tree-covered areas common across North Vancouver, Burnaby, and older parts of Vancouver proper, Cambridge shingles may show moss sooner if debris is allowed to accumulate. Landmark’s denser surface can resist initial attachment slightly better, though neither product is immune without proper ventilation and maintenance.

Local conditions accelerate wear not because the shingles are weak—but because they’re constantly damp. That’s where small material differences become noticeable over a decade.

Installation Reality — What Roofers Notice on the Job

Installation Reality — What Roofers Notice on the Job

From a roofer’s perspective, these products feel different the moment they come out of the bundle.

IKO Cambridge shingles are generally considered more forgiving during installation. They flex easily, align smoothly, and tolerate minor deck irregularities better—something that matters on older Vancouver homes with uneven decking or legacy framing.

CertainTeed Landmark shingles demand more precision. Their rigidity means nail placement and alignment matter more. When installed correctly, they lock in tightly. When rushed or misaligned, they’re less forgiving of errors—particularly in valleys, hips, and around penetrations.

Nailing zones are clearly defined on both, but Landmark’s tolerance is narrower. Missed nailing or overdriving shows up faster in the long term. Cambridge gives installers a bit more margin, which can be an advantage when working in damp conditions where pacing is slower and decks aren’t perfectly uniform.

Edge and flashing integration also differs subtly. Landmark’s thickness can make transitions feel bulkier if details aren’t planned carefully. Cambridge tends to feather into flashings more easily, which can help with clean terminations at eaves and walls.

This leads to an important reality: installation quality outweighs brand choice. A perfectly installed Cambridge roof will outperform a poorly installed Landmark roof every time in Vancouver’s climate.

Warranty & Long-Term Coverage (Real vs Paper)

Warranty & Long-Term Coverage (Real vs Paper)

On paper, both IKO Cambridge and CertainTeed Landmark offer solid manufacturer warranties—but the real-world value of those warranties in Vancouver depends far less on the fine print and far more on how the roof is installed and maintained.

Both lines typically advertise long-term limited lifetime warranties on materials, with enhanced coverage available when installed as part of a full manufacturer system. Labor coverage, however, is often limited in duration and scope, and transferability can vary depending on registration, installer status, and timing. This is where expectations and reality begin to diverge.

In practice, homeowners rarely experience warranty claims as simple or fast. Claims often hinge on proving a manufacturing defect rather than installation error or environmental exposure. In Vancouver’s climate—where heavy rain, wind-driven moisture, and moss growth are constant—manufacturers frequently point to installation, ventilation, or maintenance issues as contributing factors.

This doesn’t mean warranties are useless—but it does mean they are conditional. Granule loss caused by standing moisture, algae buildup due to shade, or wind damage linked to fastener placement can all fall outside coverage if installation standards aren’t met precisely.

Proper installation is the single biggest factor in keeping any warranty valid. Missed nailing zones, inadequate ventilation, or improper underlayment sequencing can quietly void coverage long before a homeowner ever considers a claim. In real terms, the “best” warranty is the one that never needs to be used because the roof was built correctly for Vancouver conditions from day one.

Cost Considerations & Value Over Time

Cost Considerations & Value Over Time

At the point of purchase, IKO Cambridge is typically more budget-friendly than CertainTeed Landmark, both in material cost and total installed price. For many Vancouver homeowners, this makes Cambridge an attractive option—especially when replacing aging 3-tab shingles or working within a defined renovation budget.

Landmark usually carries a higher material cost, which can translate into a noticeable difference once labor, accessories, and disposal are included. That added cost is often justified through perceived durability, brand reputation, and warranty structure.

Where value becomes more nuanced is over time. A lower upfront cost doesn’t automatically mean lower long-term value, and a higher price doesn’t guarantee better performance. In Vancouver, longevity is influenced heavily by roof design, exposure, ventilation, and maintenance, not just shingle thickness.

Cheaper becomes more expensive when:

• Premature granule loss leads to early replacement
• Moss growth accelerates aging due to trapped moisture
• Installation shortcuts create repair cycles
• Decking damage spreads unnoticed

Replacement timing also affects ROI. A well-installed shingle that lasts five extra years can easily offset a higher upfront cost. Conversely, paying more for a product installed poorly often results in earlier failure and higher lifetime cost.

The true value equation isn’t Cambridge versus Landmark—it’s correct product, correct install, correct timing.

Real Homeowner Feedback & Patterns You See in Vancouver

Real Homeowner Feedback & Patterns You See in Vancouver

Over time, clear patterns emerge across Vancouver neighbourhoods and roof types.

Granule retention is one of the most noticeable differences homeowners comment on. Landmark shingles tend to hold granules more aggressively in high-sun, south-facing exposures, especially on steeper slopes where water sheds quickly. Cambridge shingles often show more uniform granule wear across the roof, which some homeowners perceive as more even aging.

Fade patterns differ based on orientation. South-facing slopes in open areas tend to show contrast fade sooner on Landmark shingles, while north-facing, shaded slopes reveal moss and algae first—regardless of brand. In heavily treed areas, both products require attention to ventilation and maintenance to avoid accelerated aging.

Repeat customers and multi-project homeowners often report that performance differences become more pronounced on complex rooflines. Valleys, low-slope sections, and shaded transitions are where installation quality and material behavior matter most.

Neighbourhoods with older homes and uneven decking often see better outcomes when shingles are forgiving during installation. Newer subdivisions with consistent framing and predictable airflow can support stiffer, heavier products more reliably.

Slope matters too. Steeper roofs tend to shed water and debris more effectively, reducing moss pressure and extending shingle life. On lower slopes, both products are stressed more heavily by Vancouver’s moisture.

Which One Makes Sense for Your Vancouver Roof

Which One Makes Sense for Your Vancouver Roof

IKO Cambridge is often a strong choice when:

• Budget sensitivity matters
• The home has traditional or craftsman styling
• Decking is older or uneven
• A softer, more muted aesthetic is preferred
• Availability and scheduling flexibility are important

CertainTeed Landmark may be favorable when:

• Homeowners want a bolder, dimensional appearance
• The roof has good exposure and consistent framing
• Warranty structure is a priority
• The project emphasizes long-term finish and visual impact
• Installation will be done with strict attention to detail

Ultimately, the best choice depends less on brand loyalty and more on roof pitch, exposure, ventilation, shading, and budget realities. A north-facing roof under heavy tree cover has different needs than a steep, south-facing roof in an open area.

Inspection-guided selection matters. Understanding how your specific roof handles water, airflow, and sun exposure leads to better outcomes than choosing a shingle based on reputation alone.

In Vancouver, the “right” shingle is the one that matches the roof it’s going on—and is installed with the climate in mind.

Frequently Asked Questions

Are these both good upgrades from 3-tab shingles?

Yes—both are architectural (laminate) shingles and are commonly chosen as the practical step-up from basic 3-tab roofs during replacement.

Which one is better under trees and heavy shade?

Shade and debris pressure are bigger drivers than brand. In heavily treed areas, consistent ventilation, clean valleys/eaves, and basic maintenance habits often matter more than the shingle label.

Does “heavier per square” automatically mean better performance?

Not automatically. Weight can contribute to rigidity and wind feel, but Vancouver performance still depends heavily on roof geometry, detailing, and installation precision.

Why do warranties feel different in real life than on paper?

Because many claims hinge on proving a manufacturing defect rather than installation, ventilation, or maintenance factors—especially in wet climates where moisture behavior is complex.

What matters most if I’m choosing between these two?

Match the shingle to your roof’s slope, shade, detail complexity, and the crew’s installation discipline. A well-installed system is the real performance multiplier in Vancouver.
