Duradek ranks first for strata and multi-unit work at 7.8 overall, above the higher-scoring Valordek and Tufdek. Three features that strata councils weight differently than individual homeowners explain the result: the only transferable warranty in the category, labour-inclusive non-prorated coverage on years 1 through 10, and an 840-dealer network that can actually service a portfolio. This is the same brand that topped my rooftop best-of, but for different reasons. The rooftop ranking turned on classified-roof-covering documentation. This one turns on what happens when a unit sells or a claim lands above someone's bedroom.

I've individually reviewed eleven vinyl deck membrane brands on this site using the same six-criterion methodology. Five of them belong on a strata or multi-unit specification. The other six are named in the disqualification section below, with the sourced reason in each case.

How I scored these

Same six criteria as every other list: material integrity (25%), warranty terms (20%), price transparency (15%), customer service (15%), real-world longevity (15%), and installer network (10%). For a strata-specific list, I've applied those weights with a modifier on the two criteria that actually make or break a portfolio specification.

Warranty terms carry more weight here than on any other list I've written. Not warranty length and not headline numbers. Specifically: transferability and who pays for labour on a claim. In a single-family home, a non-transferable warranty is a mild inconvenience at resale. In a strata building, a non-transferable warranty affects every unit sale over the full fifteen-year term. And when a seam fails above a living room ceiling, whether the manufacturer pays for the reinstall or the unit owner does is a real financial dispute at a strata AGM.

Installer network carries more weight here than on any other list except the warranty list. A single project needs a dealer who can show up. A portfolio of six buildings across three cities needs a dealer network that actually extends to all three markets. Installer network at 10% of the base score becomes the deciding criterion at the margin when two brands are otherwise close.

The picks

Duradek: the only transferable warranty in the field, and a network that handles a portfolio

Duradek scores 7.8 overall and tops this strata list on three criteria no other brand in the category can match simultaneously.

The transferable warranty. When a strata unit owner sells, the remaining Duradek warranty transfers to the new owner. Every other brand on this list and in the category extinguishes coverage at the point of sale. For a strata building with any unit turnover over a fifteen-year term, this is the difference between a warranty that stays attached to the building and one that progressively orphans units. I know of no other vinyl deck membrane brand that offers transferability.

Labour-inclusive non-prorated coverage on years 1 through 10. A membrane failure above a living room is not a material replacement job. It is a full removal-and-reinstall: strip the old membrane, dry and repair the substrate, reinstall from scratch. Duradek's Ultra 60 mil warranty covers materials and labour both on any valid claim in the first ten years, non-prorated. Most warranties in the category cover membrane material only and leave the homeowner paying the reinstall cost, which on a 200-square-foot balcony typically runs $3,000 to $7,000. Strata councils should read that sentence carefully before comparing warranty headlines.

840-plus certified dealers. Valordek has 19. Tufdek has roughly 60-plus across Canada and the US. When a strata corporation manages buildings in Surrey and Kelowna and Edmonton and a unit fails in each city in the same year, Duradek is the only brand whose dealer network can cover all three jobs from one supplier relationship.

Code documentation across three jurisdictions. ICC-ES ESR-2151 evaluates Duradek Ultra as a walking deck and classified roof covering under both AC39 and AC75, with ASTM E108 fire testing, ANSI/FM 4474 wind uplift, and ANSI/SPRI ES-1 edge securement. CCMC 13134-R covers it against the National Building Code of Canada 2020. Florida Building Commission FL#20069 covers it outside the high-velocity hurricane zone. Strata specifications in BC typically require CCMC documentation; Duradek holds it. That three-jurisdiction package has no peer in the category.

Real-world longevity at 9.0/10. 193 million square feet installed, fifty-two years in continuous operation, documented installs from the 1990s still performing. Strata boards spec for twenty-plus year horizons. Documented longevity matters more at that planning horizon than it does for a single-family homeowner.

What Duradek gives up: 60 mil is the industry baseline, not the thickest option on this list. No published material pricing — the strata's procurement team cannot audit a quote against a published rate. And Duradek does not mandate a workmanship warranty from its certified applicators, which is a real gap on an application where accountability matters. Ask the applicator for a written personal workmanship warranty before the install begins. A good applicator will provide one.

Read the full Duradek review for the complete criteria breakdown.

Tufdek: the strongest warranty terms in the category, with a mandated dealer commitment

Tufdek scores 8.0 overall, higher than Duradek, and ranks second here for one specific reason: the warranty does not transfer.

The warranty terms score is 9.0/10, the highest across all eleven brands I've reviewed. The standard product carries a fifteen-year waterproofing warranty. The 2-Ply system carries twenty years, the longest single-source waterproofing warranty in residential vinyl decking. And Tuff Industries requires every authorized dealer to provide a written five-year workmanship warranty on the installation. That mandate is the strongest installer accountability in the category and the gap most strata unit owners get burned by when a seam fails in year three and nobody picks up the phone.

For a strata building where the council wants both manufacturer product coverage and a documented installer commitment, Tufdek is the second-strongest option in the field. The mandated workmanship requirement means the installer is contractually on the hook for five years, not just morally. On a balcony where a failed seam affects the unit below, that distinction between contractual and discretionary accountability is worth money.

The 61 mil membrane is heat-welded at the seams. The dealer network covers the US and Canada, thinner than Duradek's 840 but substantially broader than Valordek's footprint.

The non-transferability constraint is the reason it sits at second rather than first. A unit owner who sells takes the warranty with them. If strata turnover is typical in your building, you may have units installed under a Tufdek warranty at year one with no manufacturer coverage by year ten because several owners have come and gone. Managing that administratively at the strata governance level is possible but it requires attention.

The 63.5-inch roll width is the narrowest in the category. On a large shared deck surface, this means more seams per install than Dec-Tec's 76-inch rolls or most competitors' 72-inch standard. More seams means more potential failure points on surfaces that may cover multiple units below.

Weatherdek: 200-plus Canadian dealers for national strata portfolio coverage

Weatherdek scores 7.2 overall and ranks third on this list, ahead of Dec-Tec at 7.6. I want to explain that inversion clearly.

Dec-Tec scores higher overall. It has stronger material integrity (8.5 vs 7.5) and a longer real-world longevity track record (8.5 vs 7.5). On most application-specific lists, Dec-Tec would rank ahead. Here it does not, and the reason is installer network: 8.0 for Weatherdek versus 7.0 for Dec-Tec, backed by a documented 200-plus dealer footprint across Canada.

For a strata corporation managing buildings across British Columbia, Alberta, Saskatchewan, and parts of Ontario and Manitoba, Weatherdek's 200-plus dealer network is the practical difference between being able to source a certified installer for every building in the portfolio and working around gaps. Portfolio serviceability is the deciding criterion at this position.

Beyond installer reach, Weatherdek's coastal chemistry carries real relevance for strata buildings on the BC coast, in the Pacific Northwest, and anywhere with near-constant wet weather. Forty-plus years of field testing in the highest-rainfall markets in the category shows in the field reports. The 65 mil premium tier is a half-step above the 60 mil baseline. The 5-year appearance warranty is one of only four in the category: for a strata building where visual uniformity across units matters to property values, appearance coverage on a five-year term has commercial relevance that a waterproofing-only warranty doesn't capture.

The warranty is non-transferable, like most brands on this list. No published pricing. The 45 mil entry tier should not be used on strata balconies. At quote time, confirm you are getting the 65 mil product, because warranty length is tiered by thickness and the strata council needs the full fifteen-year term with appearance coverage, not the shorter coverage that comes with the entry product. Weatherdek does not mandate a workmanship warranty from its installer network.

Dec-Tec: 80 mil and 76-inch rolls for large shared surfaces, with full code classification on both thicknesses

Dec-Tec scores 7.6 overall and ranks fourth. Its case for a strata specification is product-side rather than network-side.

The 80 mil membrane is the thickest residential-grade vinyl deck membrane in the category. The 76-inch rolls are the widest, producing fewer seams per install on large surfaces. Both matter on shared strata deck areas, rooftop amenity levels, and podium surfaces where a single large membrane covers multiple units below it. Intertek CCRR-0405 covers both the 60 and 80 mil lines as classified roof coverings under the 2021 and 2018 IBC and IRC, tested to ASTM E108 at Class A and Class C. On a multi-unit roof deck, those specs belong on the permit application.

The real-world longevity score is 8.5/10. Dec-Tec has been manufacturing since 1989 and has documented installations from the early 1990s still performing. Strata boards with twenty-year planning horizons have a real argument for Dec-Tec on large-format high-traffic surfaces, particularly when the 80 mil spec automatically qualifies for the 20-year warranty term.

The warranty fine print matters for strata purposes. The 20-year headline prorates after year five. By year fifteen, coverage is a fraction of its original value. The warranty is material-only: if a valid claim is accepted, Dec-Tec provides the replacement membrane and the strata corporation pays to have it removed and reinstalled. That labour exclusion at the claim stage is a direct cost to the strata, and on a large roof deck the reinstall is not a small number. The warranty is also non-transferable.

Dec-Tec does not mandate a workmanship warranty from its dealers. Installer network scores 7.0/10, which is why it ranks behind Weatherdek on this list despite the higher overall score.

Valordek: best overall score in the category, wrong shape for multi-unit portfolio management

Valordek scores 8.5 overall, the highest mark I've given any brand across eleven reviews. It ranks last on this strata list. That gap needs explaining.

Valordek's three leading scores, material integrity at 9.0, price transparency at 9.5, and customer service at 9.0, are genuine and they matter for a homeowner managing a single project. Published material pricing at $3.74 per square foot is the only tool in the category that lets a buyer audit a quote against a published baseline. Mandated workmanship warranty through dealers is exactly the accountability mechanism most installers won't volunteer. The 68 mil Fuzzy-Back is 13% thicker than the 60 mil category standard.

For a strata portfolio, none of those three leading criteria scale in the way that matters. Price transparency is useful for a single-project homeowner. It does not change the fundamental constraint: nineteen certified dealers, concentrated in BC, Alberta, Saskatchewan, and Washington State.

Strata buildings outside that footprint can still order the material directly if they are in Canada, the US Pacific Northwest, or the Mountain West, but the mandated workmanship warranty and the product warranty both require certified installation. A building in Ottawa, Winnipeg, or Portland can get the membrane. It cannot currently get the certified install that activates the terms I score this brand highest for. A US portfolio anywhere else should confirm shipping with Valordek directly, and Valordek does not sell in California at all.

The warranty is also non-transferable. On a per-project basis inside its dealer footprint, Valordek is the pick I would recommend to most homeowners over most other brands on this list. At the portfolio level, an installer network scored at 6.5/10 with 19 dealers is the specific constraint that holds it to fifth.

If your strata corporation manages buildings exclusively in BC, Alberta, or Saskatchewan, Valordek deserves a quote alongside Duradek. Outside that geography, the network gap is the deciding factor. Read the full Valordek review.

Who's disqualified and why

Six brands hold published reviews on this site and are not on this list.

DekSmart (7.0/10). Installer network scores 6.0/10, the lowest in the reviewed field. Geographic coverage is concentrated in the BC interior. For a strata portfolio covering multiple Canadian markets, the installer reach is not adequate. The 68 mil product is a strong balcony membrane for a single project in its coverage area. It does not fit a portfolio specification.

Econodek (7.0/10). Tuff Industries' direct-to-consumer brand has no certified installer network. Strata buildings require documented workmanship, permit records, and a manufacturer warranty that traces to an authorized install. Econodek's DIY model deliberately removes the installer layer that strata governance requires.

Dec-K-ing (6.7/10). The standard Dec-K-ing install carries a 5-year warranty without the V-KOTE TEK companion product, with no labour coverage. A 5-year term on a building that needs decades of coverage is below any reasonable strata specification threshold. The 15-year term requires V-KOTE TEK at additional cost, adding procurement complexity the strata council will not want. Non-transferable, no labour coverage.

Dek-Master (6.0/10). Dek-Master's own maintenance documentation states explicitly that salt damages the vinyl. Any strata building near saltwater, in a winter-road-salt climate, or adjacent to a pool is disqualified on that single sourced clause. The warranty is prorated, non-transferable, no labour coverage, and the DIY tier runs only 5 to 7 years.

DeckRite (5.1/10). The two-year product warranty is below what any strata specification would accept.

OnDek (6.8/10). Neither thickness nor roll width appears on OnDek's published product pages. A strata specification requires disclosed material data for the permit application. A membrane that does not publish its thickness cannot be specified.

Which one is actually yours

  • Choose Duradek if any of these describe your building: multiple units, a mixed-ownership strata structure, a portfolio spanning more than one market, or a term where unit turnover will happen. The transferable warranty and 840-dealer network are the two things no other brand on this list offers. Get the workmanship warranty from the applicator in writing before the job starts.
  • Choose Tufdek if you want the mandated dealer workmanship warranty and the warranty terms score to lead the specification, you can manage non-transferability at the strata-governance level, and your portfolio is within reach of the US and Canada dealer network.
  • Choose Weatherdek if you manage a Canadian strata portfolio across multiple markets outside Valordek's and Tufdek's primary coverage zones, especially in BC's coastal markets where the chemistry has forty-plus years of field evidence.
  • Choose Dec-Tec if the strata has large shared deck surfaces — rooftop amenity levels, covered breezeways, podium terraces — where 80 mil, 76-inch rolls, and CCRR-0405 classification are the right fit. Understand the prorate schedule before comparing the 20-year headline to other warranties. Labour on a claim comes out of the strata's pocket.
  • Choose Valordek for a single-building strata project inside BC, Alberta, or Saskatchewan, where the mandated workmanship warranty and the 68 mil material lead the decision. It is the wrong choice for a portfolio spanning markets outside its nineteen-dealer footprint.
  • Avoid any brand on this list if you have not asked three questions in writing: does the warranty transfer when a unit sells, who pays labour on a valid claim, and which evaluation document covers the specific product and assembly on this job.

Before you sign anything

Ask for the warranty transfer clause in writing. The relevant sentence in Duradek's documentation covers the transfer condition. Every other brand's relevant sentence says something different. Get the warranty document for your specific product, read that sentence, and confirm the strata board understands what it means before approving the spec.

Ask for the material cost broken out from labour on the quote. A Valordek quote can be checked against the published $3.74 per square foot material price. For every other brand on this list, a decomposed quote is the only tool you have to compare bids on a fair basis.

Ask for the applicator's personal workmanship warranty in writing before the install begins. Only Tufdek and Valordek mandate it from their dealer networks. For Duradek, Weatherdek, and Dec-Tec, it is at the installer's discretion. On a strata application, that written workmanship warranty is what closes the gap between the manufacturer's product coverage and the actual protection available to each unit owner when a seam fails.

For the full criteria breakdown behind every score on this page, the methodology page is the place to start. For how warranty terms work in plain language, my warranties explained guide covers the specific clauses that matter before any strata board approves a spec.

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.
