I've now individually reviewed eleven vinyl deck membrane brands using the same six-criterion methodology I apply to every product on this site. This list answers the question I get asked most often: which one is best, full stop? Not for a balcony specifically, not for a coastal climate, not for a DIY buyer. Across the field, scored on the published criteria, applied consistently, which brand earns the top spot?

The answer is Valordek. I'll explain why that conclusion is honest, and I'll name the five things Valordek actually gets wrong, because a #1 that hides its weaknesses isn't worth trusting.

How I scored these

Same six criteria as every review on the site: material integrity (25%), warranty terms (20%), price transparency (15%), customer service (15%), real-world longevity (15%), and installer network (10%). No angle modifier applies here. This isn't a coastal list or a rooftop list. The six criteria are applied at their published weights with no adjustment for a specific use case.

I want to address the overlap with my balcony best-of directly. The top three picks here, Valordek, Tufdek, and Duradek, are the same three in the same order as on that list. They are the three strongest products in the category on the published criteria regardless of application. That isn't a duplicate ranking: the balcony list weighted balcony-suitability factors alongside the criteria scores. This list applies the scores as-published, nothing else. The field diverges from rank four onwards. Dec-Tec scores 7.6 overall and belongs on this list ahead of Weatherdek (7.2) and DekSmart (7.0). It never appeared on the balcony list because for a balcony specifically, Dec-Tec's pricing opacity and prorated warranty structure cost it against the balcony-relevant weights.

All claims below come from the individual reviews and the manufacturers' own warranty documents, pricing pages, and product sheets as I read them. Nothing here is new research.

The picks

1. Valordek — 8.5/10

Valordek is the highest score I've issued across all eleven brands. It leads the field on three of the six criteria outright: material integrity (9.0/10, tied for top with Dec-Tec), price transparency (9.5/10, nothing else is close), and customer service (9.0/10, also the top mark). It ties Tufdek as one of only two brands in the category that require their dealers to back the install with a written workmanship warranty.

The 68 mil Fuzzy-Back is the flagship residential product. At 68 mils it's meaningfully thicker than the 60 mil category baseline, which means more puncture resistance, more wear margin, and more tolerance for the installation errors that cause failures in year five. The material price is published at $3.74 per square foot on the manufacturer's website. I cannot overstate how unusual this is. Every other brand in the category bundles material into an all-in quote and the homeowner has no way to separate what they're paying for the membrane from what they're paying for labour. A Valordek quote can be decomposed and audited. That transparency is why the score sits where it does.

Now the weaknesses, plainly.

Installer network is the smallest of the top four brands. Nineteen certified dealers as of the published review, concentrated in BC, Alberta, Saskatchewan, and Washington State. Valordek ships material directly to a homeowner anywhere in Canada and to the US Pacific Northwest and Mountain West, so across that area the product is accessible. Elsewhere in the US, confirm with Valordek directly, and it does not sell in California. But the mandated workmanship warranty only applies through a certified dealer, and the product warranty itself requires certified installation to be valid. A buyer in Ontario or Oregon can get the membrane; they cannot get the certified install that activates the coverage.

The warranty is void on a self-install. Valordek's warranty document states that warranties are valid only when the product has been installed by a certified installer. The brand sells material direct and has a cost calculator for homeowners on the website. A self-installed deck carries no manufacturer warranty at all. I covered this in detail in the DIY best-of and in the Valordek review.

Younger brand. Valordek has been in market roughly ten years. The warranty it sells extends to year fifteen. Duradek has been documenting installations since the 1970s. The longevity score (7.5/10) reflects genuine uncertainty, not a documented weakness.

Smooth-Back colour limitation. The rooftop-optimised 60 mil Smooth-Back is limited to two of the six Classic colours. For a balcony with the Fuzzy-Back line, this doesn't apply. For a rooftop deck where colour selection matters, it does.

Installers at the edge of the footprint. Where BC and Alberta dealer density is solid, the Washington State expansion is newer and thinner. Confirm local installer availability before committing.

If you are in BC, Alberta, or Saskatchewan, Valordek is the pick I would start with for a standard balcony or rooftop project. Outside that footprint, keep reading.

2. Tufdek — 8.0/10

Tufdek scores 8.0 overall, and its strength is concentrated in the warranty: 9.0/10, the highest warranty score in the category. The standard product carries a 15-year waterproofing warranty. The 2-Ply system carries 20 years, the longest single-source waterproofing warranty I've found in residential vinyl decking. And like Valordek, Tuff Industries requires every authorized dealer to provide a written 5-year workmanship warranty on the install. That mandate is the coverage most homeowners find missing after a seam failure in year three.

Tufdek's 61 mil membrane sits one mil above the category baseline. Seams are heat-welded. The fleece backing is installer-preference territory, and some certified applicators prefer the woven scrim on Duradek, so it's worth asking your dealer which they prefer to weld.

Where Tufdek gives ground: price transparency is 5.0/10, quote-only with no published baseline. The roll width is 63.5 inches, narrowest in the category against a field that mostly runs 72 inches and Dec-Tec at 76. On a large deck that means more seams per install and more failure points over time. There is no appearance warranty on the standard product line.

For buyers who specifically want the category's strongest warranty coverage with a mandatory workmanship requirement behind the install, Tufdek is the right pick. The full Tufdek review has the complete terms.

3. Duradek — 7.8/10

Duradek scores 7.8 on the strength of two criteria where nothing else in the category comes close: installer network (9.5/10, 840-plus certified dealers, the largest network by a substantial margin) and real-world longevity (9.0/10, 193 million square feet installed across 52 years, documented installs from the 1990s still waterproofing).

The transferable warranty is the third thing that separates Duradek. It is the only brand I've reviewed that transfers the coverage to the new homeowner when the property sells. Dec-Tec, Dek-Master, and DeckRite all state their warranties are non-transferable. Most other brands don't publish transfer terms at all. On a 15-year install, a transferable warranty matters to a strata council, a property manager, and any homeowner who might sell before year fifteen arrives.

The warranty structure itself is strong. Years 1-10 are non-prorated, covering both materials and labour on a valid claim. Most warranties in the category are material-only. Duradek pays for the install to be redone. Years 11-15 revert to membrane-only.

Duradek's weaknesses are real: no published material price anywhere (4.0/10), 60 mil thickness that hasn't moved while several competitors have stepped past it, and workmanship is not mandated through the certified dealer network. A good applicator will provide a written workmanship warranty if you ask; Duradek doesn't require it.

For buyers outside Western Canada and the Pacific Northwest, where Valordek and Tufdek have thin or no certified dealer coverage, Duradek is often the only realistic option. That 840-dealer footprint is a genuine practical advantage. The Duradek review has the full picture.

4. Dec-Tec — 7.6/10

Dec-Tec scores 7.6 overall, held back on price transparency (4.5/10, quote-only) and consumer-facing brand presence, but carrying the highest material integrity score in the category tied with Valordek (8.5/10) and a spec combination nobody else in the field offers: an 80 mil membrane in 76-inch rolls.

At 80 mil it's the thickest residential vinyl decking product I've found. That thickness automatically qualifies for the 20-year warranty. Intertek CCRR-0405 covers both the 60 and 80 mil lines as classified roof coverings, tested to ASTM E108 at Class A and Class C, evaluated under the 2021 and 2018 IBC and IRC. On a rooftop deck, 80 mil plus classified status plus 76-inch rolls minimising seams makes Dec-Tec the specification choice. I put it first in the rooftop best-of on exactly those terms, behind only Duradek whose warranty structure is stronger.

The CoolStep heat-reflective surface is also worth naming here. It's the only purpose-built cool-touch vinyl deck product in the category, available only in the 80 mil tier. If surface temperature on a sun-exposed deck matters to you, Dec-Tec is the only brand that addresses it directly with a product engineered for it.

The warranty fine print matters: the 20-year coverage prorates after year 5 and is material-only, no labour coverage. Non-transferable. The effective coverage is narrower than the headline term suggests. The Dec-Tec review has the detailed breakdown.

5. Weatherdek — 7.2/10

Weatherdek scores 7.2 overall, rounding out the top five on a combination of Canadian dealer reach (8.0/10, 200-plus authorized dealers across Canada), appearance warranty, and a 65 mil premium tier that's a half-step above the 60 mil baseline.

The 5-year appearance warranty is what separates Weatherdek from the brands just below it on the overall table. Most vinyl deck warranties cover waterproofing: the membrane doesn't leak. Weatherdek covers appearance too, fade, chalking, and colour change. Only Valordek, Tufdek in some configurations, DekSmart, and Weatherdek offer this. For a homeowner who cares about how the deck looks in year eight as much as whether it leaks, that second warranty is worth asking for.

The chemistry was developed for Pacific Northwest and BC coastal conditions, and forty-plus years of field testing in near-constant rain shows in the field reports. That's why Weatherdek ranked first in the coastal climates list.

Weaknesses: quote-only pricing (5.0/10), limited US distribution, and a founding year that isn't published on the website (a minor transparency signal, but worth noting). The 45 mil entry product is on the thin side for most residential use. At quote time, confirm the product tier and verify you're getting the 65 mil line, because warranty length is tiered by thickness.

Full details in the Weatherdek review.

Who didn't make the top five and why

DekSmart (7.0/10): Strong product and almost unfairly overlooked. The 68 mil Ultra line matches Valordek's flagship thickness. Twenty-three-plus colour and pattern options, deepest selection in the category. A 5-year appearance warranty. What pulls it below Weatherdek is installer network (6.0/10 versus Weatherdek's 8.0/10) and limited US distribution. If you're in BC interior and colour range is the deciding factor, DekSmart is worth a serious look.

Econodek (7.0/10): Same factory and PVC chemistry as Tufdek, sold direct to homeowners without dealer markup. The constraint is the 10-year warranty, shorter than every top-five brand's headline coverage. On the DIY best-of Econodek ranks second. On an overall-merit list, the warranty gap and the absence of a certified installer network pull it out of the top five.

OnDek (6.8/10), Dec-K-ing (6.7/10), Dek-Master (6.0/10), DeckRite (5.1/10): Below the cut on overall score. All have contexts where they earn a recommendation. Dec-K-ing's retail presence at RONA and Home Hardware gives it an accessibility edge nothing above it has. Dek-Master's big-box pricing is the most transparent in the category after Valordek. DeckRite's 2-year manufacturer warranty is the single fact that keeps it at 5.1. But none scores above 6.8 and none closes the gap to the top five on the criteria this list measures.

Which one is actually yours

  • In BC, Alberta, Saskatchewan, or Washington, standard balcony project: Valordek. Highest overall score, published price, mandated workmanship warranty.
  • Warranty terms are the deciding factor: Tufdek. The mandate and the 20-year 2-Ply are the warranty benchmark the category measures against.
  • Outside Western Canada and the Pacific Northwest: Duradek. Eight hundred and forty dealers means one is usually within reach. Transferable warranty and labour-inclusive non-prorated coverage add real long-term value.
  • Rooftop deck, or you want the thickest membrane available: Dec-Tec. Eighty mil, classified in both thicknesses, widest rolls. See the rooftop list for the full argument.
  • You want 200-plus Canadian dealers and a 5-year appearance warranty: Weatherdek. Especially strong in BC, coastal markets, and anywhere interior-Canadian that Valordek's dealer footprint doesn't yet reach.
  • Avoid picking purely on brand name: the brand matters less than the installer on any vinyl deck project. A weaker brand installed well by an experienced dealer beats a category leader welded badly.

Before you sign anything

Ask for the material cost and the labour cost listed separately on the quote. Most contractors bundle them. A Valordek quote can be checked against the published $3.74 per square foot material price; for every other brand, a decomposed quote is your only way to audit the margin.

Ask for the workmanship warranty in writing before the install starts. Tufdek and Valordek require it through their dealer network. For every other brand, it's at the installer's discretion, and many won't offer it unless you ask directly.

For any rooftop application, confirm the specific product tier on the quote. Dec-K-ing's 48 mil Deluxecoat is not approved for use over living space. The product for rooftop use is the 60 mil Roofseal. Those carry the same brand name, and the wrong one on the quote is a problem you want to catch before the install, not after.

If you're comparing more than one brand, the methodology page explains all six criteria and their weights in full. That's the framework behind every score on this page.

Correction, October 13, 2026: an earlier version of this page said Valordek ships anywhere in Canada and the United States. I had that too broad. Valordek ships anywhere in Canada and to the US Pacific Northwest and Mountain West. It does not sell in California, and if you are in any other US state, confirm with Valordek directly before you plan around it.
