Overview

EN 544:2011 - produced by CEN - is the European product specification and test-method standard for bitumen shingles with mineral and/or synthetic reinforcements. It specifies required properties, test methods, marking and conformity assessment for finished shingles prior to installation. The standard applies to shingles intended for pitched roofs and/or wall cladding where watertightness is achieved by overlapping and/or adhesive systems according to the manufacturer’s instructions. Design requirements, installation techniques and whole roof system performance are explicitly excluded.

Key topics and requirements

This standard defines the measurable attributes and test procedures that manufacturers and test laboratories must use. Major technical topics include:

• Materials and construction

  • Requirements for bitumen content, mineral and synthetic reinforcements, and surfacings (upper and underside).
  • Multilayer shingles: each layer must use the same type of reinforcement and coating (see Clause 8).

• Geometrical properties

  • Shingle shapes, widths, heights and overlapping surfaces required for consistent manufacturing and installation fit.

• Mechanical properties

  • Tensile strength and nail shank tear resistance tests to verify mechanical durability and fastening performance.

• Durability and ageing

  • Tests for water absorption, resistance to UV radiation, blistering, flow resistance at elevated temperature, and adhesion of mineral granules/slate flakes.

• Fire performance

  • Reaction to fire and external fire performance requirements and test methods.

• Sampling, test methods and conformity

  • Detailed sampling procedures, laboratory test methods, Initial Type Testing (ITT) and Factory Production Control (FPC) requirements.
  • Rules for designation, marking and labelling, and guidance for an EC Declaration of Conformity and CE marking (Annex ZA).

Practical applications - who uses EN 544:2011

• Manufacturers: to develop, certify and quality-control bitumen shingles and to prepare product data sheets.
• Test laboratories: to perform standardized sampling and laboratory tests for compliance.
• Specifiers and architects: to select products based on standardized mechanical, durability and fire attributes.
• Building authorities and procurement teams: to assess conformity, CE marking and documentation under EU Construction Products rules.
• Roofing product certifiers and inspectors: to audit Factory Production Control and verify marking/labeling.

Related standards and documents

• Annex ZA links this standard to the EU Construction Products Directive (CPD) for CE marking and conformity assessment.
• EN 544:2011 supersedes EN 544:2005; consult national standards bodies for endorsed national versions and complementary standards for roofing materials and installation best practice.
