Methodology

How the estimates were built: data sources, modelling approach and validation steps.

Research approach

A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.

Market size estimation, this report

The estimate is built upward from unit volumes and realised prices for breathable roofing felt, starting with square metre shipment volumes reported by manufacturers of polypropylene and polyethylene nonwoven substrates, then applying average selling prices by type and by end-use tier: residential underlayment versus premium PTFE and PU membranes used in commercial and high-specification renovation work. Regional production capacity and customs codes covering nonwoven roofing underlayment provide a cross-check on shipment volumes where manufacturer disclosure is incomplete. The resulting bottom-up total is compared against revenue disclosed by the largest named suppliers in their building-materials segments; where a gap appears, the underlying volume or price assumption is corrected, not the total itself.

The four stages

The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.

What the build rests on, and what checks it

The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.

The bottom-up build rests on
  • Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
  • Realised pricing by tier and channel, rather than one blended average applied across the whole market
  • Take-up and frequency: how much of the addressable base buys, and how often it repeats
The build is checked against
  • Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
  • Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
  • Trade and customs flows, where the product crosses borders in a separately recorded form

Data sources

Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.

Primary — who is interviewed
  • Commercial and product leadership at the companies that supply the market
  • Procurement and specification leads at the organisations that buy it
  • Distributors, integrators and channel partners, where the market is served indirectly
  • Regulatory and standards specialists, where approval governs what can be sold at all
Secondary — what is read
  • Company filings, annual reports and investor disclosure
  • Government statistics, customs records and regulatory registers
  • Trade association output and standards-body publications
  • Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Primary research design, this report

Primary outreach targets procurement managers at roofing contractors and distributors, technical specifiers at architecture and building-envelope consultancies, and regulatory affairs contacts at national roofing and waterproofing trade associations: specification decisions for breathable membranes sit with these roles, not with end building owners. Sampling weights Europe, where building-envelope airtightness codes are most developed and adoption is furthest along, alongside North America and the fastest-growing Asia Pacific markets where construction activity is concentrated. Conversations focus on which membrane properties (vapor permeability rating, tear strength, UV exposure tolerance) actually drive a purchase decision, and how distributor stocking patterns differ between new-build and renovation channels.

Secondary sources, this report

Desk research draws on national building-code registers that set vapor-permeability and airtightness requirements for pitched roofs and walls, customs trade data filed under the harmonised code covering nonwoven roofing underlayment, and construction-output statistics published by national statistical offices and by Euroconstruct for the European renovation market specifically. Trade-body benchmarks from national roofing contractor associations and waterproofing material associations provide shipment and specification trends where company disclosure is silent. Public filings and investor materials from the named manufacturers supply revenue and capacity detail used in the top-down check described above.

Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.

Forecasting

The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.

Forecast approach, this report

The forecast is built from the pace at which national building codes extend airtightness and vapor-control requirements from new construction into renovation work. That extension moves demand from the mature new-build channel into the faster-growing retrofit channel. Polymer feedstock pricing is normalised against its recent volatility instead of projected forward at spot levels, since membrane manufacturers typically pass cost swings through with a lag. Adoption of PTFE and PU membranes in premium and commercial specification is assumed to continue displacing PE at the rate observed over the last two historical years, without assuming a step change in either regulation or material substitution.

Triangulation and validation

No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.

Validation, this report

Each forecast year is back-tested against the compound growth actually recorded between 2020 and 2025 for the corresponding sub-segment, so a projected acceleration must be explained by a specific driver, not carried forward by default. Segment-share shifts between membrane types and between new construction and renovation are reviewed against the same specification contacts consulted in primary research to confirm the direction, not just the magnitude, is credible. Sensitivities are run on polymer feedstock pricing and on the pace of renovation-driven code adoption in Europe: these are the two assumptions the forecast is most exposed to if either moves faster or slower than assumed.

Confidence and limitations

Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.

Confidence framing, this report

Estimates for the by-type split and for the largest national markets in Europe and North America rest on reasonably firm shipment and pricing data and are the most reliable figures in this report. The distribution-channel and construction-type splits are triangulated from a thinner set of disclosures and should be read as directional rather than precise. Asia Pacific volumes carry more uncertainty because reporting from regional manufacturers is less consistent than in Europe or North America. A structural risk to the entire forecast is a slower-than-assumed extension of airtightness codes into renovation work, shifting volume back toward the lower-margin new-build channel.
