ClassicBond One Piece EPDM Rubber Roof Covering 1.20mm – Cut to Size

ClassicBond 1.20mm EPDM Rubber Roof Covering is a durable, flexible and long-lasting flat roofing membrane with a proven service life of more than 50 years.

Manufactured by Carlisle SynTec, a pioneer of EPDM roofing systems since the 1960s, ClassicBond provides a reliable waterproof covering for extensions, garages, garden rooms, sheds, dormers, porches and other flat or low-slope roofs.

The 1.20mm standard-grade EPDM membrane can be supplied in exceptionally large sheets, up to approximately 15.25m wide x 30m long. For most domestic flat roofs, this allows the entire roof to be covered using a single piece of EPDM without seams across the main roof area.

Combined with the appropriate ClassicBond adhesives, edge trims, flashing products and accessories, the result is a professional, low-maintenance rubber roofing system designed for decades of service.

One-Piece EPDM Rubber Roofing

One of the biggest advantages of ClassicBond EPDM is the size of membrane available.

The 1.20mm membrane can be supplied from large sheets starting at approximately 1m wide, increasing in 1m width increments, with lengths available up to 30 metres and a maximum sheet width of approximately 15.25 metres.

Where your required membrane falls within the available sheet dimensions, ClassicBond can normally be supplied as one continuous piece.

This eliminates the need for field seams across the main roof area, making installation quicker and reducing the number of joints that require waterproof detailing.

Cut to Size for Your Flat Roof

Rather than purchasing multiple small rolls of roofing material, ClassicBond EPDM can be cut specifically to suit your project.

This makes it particularly suitable for:

• Flat roof extensions
• Garages
• Garden rooms
• Sheds
• Porches
• Dormer roofs
• Workshops
• Outbuildings
• Flat roof repairs
• Replacement flat roofs
• New-build flat roofs

For most domestic applications, a single sheet can cover the entire main roof area.

Important: Add 150mm to Every Roof Edge

When measuring your roof, you must allow additional EPDM membrane for roof edges, upstands and perimeter detailing.

Add approximately 150mm to every edge of the roof.

For a straightforward rectangular roof, this normally means adding approximately 300mm to the overall roof length and 300mm to the overall roof width.

For example:

Actual roof size: 5.7m x 2.7m

Recommended membrane size:

6.0m x 3.0m

The additional material provides approximately 150mm around each edge for the required perimeter detailing.

Always measure the actual roof carefully before ordering.

Roofin cannot accept responsibility for membrane ordered using incorrect measurements.

Bespoke Cut-to-Size Product

ClassicBond EPDM membrane is cut specifically to the dimensions selected when placing your order.

As this is a bespoke cut-to-size product, it cannot be returned once dispatched.

Please check the roof dimensions carefully before ordering and remember to include the required additional membrane for edges, upstands and other roof details.

1.20mm Standard-Grade ClassicBond EPDM

ClassicBond EPDM is available in two principal membrane thicknesses:

• 1.20mm Standard Grade
• 1.52mm Commercial Grade

This product is the 1.20mm standard-grade membrane, making it an excellent general-purpose choice for domestic flat roofing applications.

For projects requiring a heavier-duty membrane specification, the 1.52mm commercial-grade ClassicBond EPDM is also available.

Fully Adhered EPDM Roofing System

ClassicBond is installed as a fully adhered roofing system.

The membrane is bonded to the appropriate roof substrate using compatible ClassicBond adhesives, with different adhesive products used according to the roof deck and detail.

A typical timber-decked installation may use:

• Water Based Deck Adhesive across the main horizontal roof area
• Contact Bonding Adhesive around the roof perimeter
• Contact Adhesive around upstands and appropriate vertical details

Additional ClassicBond tapes, primers, flashing materials and accessories can then be used to complete corners, penetrations, outlets and other roof details.

BBA Certified EPDM Roofing System

ClassicBond is a BBA certified roofing system, providing independent technical assessment for appropriate roofing applications.

Its established performance and straightforward installation make it suitable for professional roofing projects as well as competent DIY installations.

More Than 50 Years of EPDM Roofing Performance

EPDM has been used as a roofing material for decades and has established an extensive track record in both domestic and commercial flat roofing.

ClassicBond is manufactured by Carlisle SynTec, which pioneered EPDM roofing systems in the 1960s.

The system offers a proven service life exceeding 50 years, providing a long-term alternative to roof coverings that may require more frequent replacement.

UV & Ozone Resistant

EPDM is particularly well suited to long-term external exposure.

ClassicBond membrane provides excellent resistance to:

• UV radiation
• Ozone
• Weathering
• Seasonal temperature changes
• High and low temperatures

This allows the membrane to maintain its flexibility and waterproofing properties over an extended service life.

Performs Across Extreme Temperatures

ClassicBond EPDM is designed to remain flexible across a wide temperature range.

Within a stated range of approximately -40°C to +120°C, the membrane is resistant to:

• Cracking
• Peeling
• Splitting

This flexibility allows the EPDM to accommodate normal thermal and structural movement within the roof.

Strong Yet Lightweight

ClassicBond EPDM combines durability with relatively low weight, making the membrane easier to handle and install than many traditional multi-layer flat roofing systems.

Its flexibility also makes it easier to dress around roof edges, upstands and other details when installed using the appropriate ClassicBond system components.

Slate Grey Appearance

ClassicBond EPDM has a natural slate grey finish, providing a clean and understated appearance on both modern and traditional buildings.

The membrane can be combined with appropriate ClassicBond or Sure Edge perimeter trims to create a neat finished roof edge.

Depending on the roof design, these can include:

• Gutter drip trims
• Kerb edge trims
• Wall trims
• Corner trims
• Other compatible EPDM perimeter details

Suitable for DIY Flat Roofing

The combination of a large one-piece membrane and cold-applied adhesive system makes ClassicBond particularly suitable for competent DIY flat roofing projects.

Where a roof can be covered using a single membrane, there is no requirement to construct multiple seams across the main roof area.

The membrane can be positioned over the roof, allowed to relax and then bonded using the appropriate ClassicBond adhesive system.

Complex roof shapes, penetrations and drainage details may require additional tapes, primers and accessories.

ClassicBond 1.20mm vs 1.52mm EPDM

Both ClassicBond membrane thicknesses provide the benefits of an EPDM rubber roofing system, but they are intended to offer different specifications.

ClassicBond 1.20mm

The standard-grade membrane and an excellent choice for:

• Domestic flat roofs
• Extensions
• Garages
• Garden rooms
• Porches
• Dormers
• Sheds and outbuildings
• General flat roof refurbishment

ClassicBond 1.52mm

The thicker commercial-grade option, suitable where a heavier-duty EPDM membrane specification is preferred.

For most standard domestic flat roofing projects, ClassicBond 1.20mm provides the established general-purpose solution.

Complete ClassicBond Roofing System

ClassicBond EPDM can be combined with a comprehensive range of compatible roofing accessories to complete the roof.

Depending on the project, these may include:

• Water Based Deck Adhesive
• Contact Bonding Adhesive
• Rubber Primer
• 3 Inch Splice Tape
• 6 Inch Cover Tape
• 9 Inch Elastoform
• Internal and external corner patches
• Pipe boots
• Internal drains
• Horizontal drains
• Kerb edge trims
• Gutter drip trims
• Wall trims
• Mastics and sealants

This allows everything from a straightforward rectangular garage roof to more complex roofs with walls, pipes, outlets and other penetrations to be detailed using compatible system components.
