Advantages of EPDM

• EPDM waterproofing membranes are permanently flexible and have a life expectancy of at least 50 years
• EPDM waterproofing membranes are highly resistant to UV and infra red light, without the need for additional surface protection.
• EPDM waterproofing membranes offer exceptional resistance to the effects of weather, environmental chemicals and aggressive industrial emissions.
• EPDM waterproofing membranes are extremely resistant to heat, cold, ozone and ageing.
• EPDM gives off no toxic emissions in the event of fire and the membrane is suitable for thermal recycling even after it has been laid for many decades.
• EPDM is extremely elastic, with no shrinkage or dimensional changes over a temperature range from -40 to +120 Degrees Centigrade.
• EPDM is considered an Environmentally friendly alternative to traditional methods

Applications

• Flat Roof Extensions EPDM rubber roofing is the obvious alternative to traditional felt, bitumen or asphalt. Not only does it have superior resilience, strength, good looks and is environmentally friendly but the rubber membranes are also incredibly easy to install. Read More…..Flat Roof Extensions
• Flat Roof GaragesIf your garage is not attached to your home then in most cases it does need to comply with building regulations. If you intend to install an EPDM rubber roof to your garage you will need to ensure the sub base is flat and sound.Flat Roof Garages
• Green Roofs using Rubber MembraneA Green roof also known as eco-roof or living roof is a roof of a building that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane. EPDM Rubber is widely used as the waterproof membrane for green roof constructionGreen Roofs using Rubber Membrane
• Rubber Roof for Dormer windowThere is nowhere better than a dormer to fit a rubber roof! Dormer roofs are difficult to get to due to their height so its essential that you have a long lasting roofing system such as an EPDM rubber roof membrane.Rubber Roof for Dormer window

FAQ

• Can I walk on the EPDM Rubber Roof?

  The EPDM sheet supplied can be walked on both during and after installation EPDM is designed to take LIGHT foot traffic for occasional cleaning or maintenance. However common sense needs to be applied. Avoid studded boots and shoes. If you intend to use a ladder on the roof use a plank or board to spread the load.

• Is the EPDM membrane guaranteed?

  Yes. The expected lifespan of EPDM membrane is in excess of 50 years. Rubber4Roofs Ltd offers a membrane guarantee for 20 years on its ClassicBond One-Piece system.

• Can EPDM sheets be joined?

  The “One Piece” sheet comes in four widths 9.0, 6.0, 4.5 & 3.0 metres. If your project requires a size in one direction larger than this then the material can be easily joined. We will cut to length to suit your roof.

  There are times such as with an ’L’ shaped roof where it is more cost effective to buy two pieces and join rather than cut a corner out of one sheet and discard.

  It is important to consider the weight of any one piece of EPDM as it will need to be safely lifted into position on the roof. The One piece system weighs 1.27Kg/m2

  Fortunately the joining system is a very simple but effective solution. Typically a splice tape is used to provide a strong watertight seal. The correctly joined seam will be as strong as the material itself.

  The roof membranes to be joined must be primed where they overlap and touch dry prior to applying the splice tape. Please see our detailed One Piece training manual

• Which EPDM system is best for me?

  Our easiest system to install - The One Piece system is ideal for large uninterrupted flat or shallow pitch roofs such as garages, commercial flat roofs and residential properties. The One Piece is cheaper than the Self adhesive system and is fully BBA certified to comply with building regulations.

• How Do I Bond The EPDM Sheet To My Roof?

  In most cases the Water based bonding adhesive is used. Unlike the solvent based contact adhesive which must be used on vertical surfaces, the water based adhesive can be used in damp conditions and allows easy repositioning of the membrane whilst installing.

  The Contact adhesive may be used in place of the water based adhesive where the substrate requires.

  Please contact us directly for further information.

• Do I Need Any Special Tools?

  No! - Basic hand tools like scissors, paint rollers and disposable paintbrushes are all that is required. A soft bristle broom or squeegee is ideal for smoothing out the membrane to remove air pockets. In most cases you will require no special tools, we do however recommend purchasing a penny roller and flat seam roller for ensuring a watertight seal when joining membranes with splice tape of fitting pipe boot covers.

• What Is The Maximum Sheet Size?

  The “One Piece” sheet comes in four widths 9.0, 6.0, 4.5 & 3.0 metres by 30 metres long. If your project requires a size in one direction larger than this then the material can be easily joined using splice tape and primer.

  All orders are supplied by the fixed width and cut to length.

• Can EPDM Be Laid Over Existing Roof Coverings?

  EPDM membrane can be laid over existing felt, bitumen, Fibreglass, cement boards and steel roof cladding. In some cases these substrates may require specialist adhesives or mechanical bonding.
  Remember when installing any roof membrane it is equally important that the roof structure/decking is sound and rot free. This can normally only be assessed by removing the old waterproof material.
  Make sure all sharps are removed. If necessary fix a thin plywood board over the old roof cover to achieve a superior bond and finish to the EPDM rubber Sheet.

• How do I install slabs or tiles on a flat roof?

  Can I install tiles or slabs directly on to a flat roof?

  There are a couple of options here depending on the type of slab or tile.

  1) A slab space can be used to support the concrete slabs above the EPDM flat roof rubber membrane. These are a 15mm high circular plastic disc that supports the corner of 4 slabs in a standard check board pattern. Water will pass through the gaps in the slabs and safely away to the gutter.

  2) If you are installing a tile on the flat roof that requires fully bonding then subject to roof loads it is perfectly acceptable to install a minimum 50mm screed on top of the rubber membrane (using an underlay fleece to protect the rubber from sharps) Tiles or slabs can then be bonded and grouted on to the cement screed.

• Can I install a cement screed on top of the EPDM rubber membrane.

  Yes! EPDM rubber membranes are not effected by cement or the lime additive unlike TPO and plastic single ply membranes so the EPDM rubber membrane can be screeded over or bonded directly to a smooth concrete surface if required

• What is a Geo-textile underlay or underlay used for in relation to flat roofing?

  The Geotextile underlay fleece can be used in a number of ways:

  1. The Geotextile fleece can be used under the rubber membrane when installing directly over the old roof to protect it from sharps that may puncture the rubber membrane. In this scenario the rubber membrane can not be glued in place so is either secured using Russ strips (A Grid of mechanically fixed bonding strips) or ballasted in position with pebbles or a green roof.

  2. The Geo-textile underlay can be used on top of the rubber membrane to protect it from sharp objects when it is planned to either ballast (cover) the membrane with pebbles for fire protection.

  3. The Geo-textile underlay fleece can be used on top of the rubber membrane to protect it from sharp objects when a cement screed is being installed on top of the rubber membrane to provide a hard wearing surface for slabs or tiles.

• How is natural and synthetic rubber produced?

  Natural Rubber
  Today more than 90% of the natural rubber supply comes from Southeast Asia. As rubber trees require a hot, damp climate, they grow only in the “Rubber Belt,” an equatorial zone that stretches around the world. In 1876, the English, in recognition of the difficulties of securing quality rubber from the jungle, hit upon the idea of growing rubber on plantations. From their efforts, the cultivated rubber tree plantations of Southeast Asia and Africa have developed.

  Synthetic Rubber
  General purpose synthetic rubber has its origin in two gases: butadiene, a by-product of petroleum refining, and styrene, captured either in the coking process or as a petroleum refining by-product. When the two are mixed in the presence of soapsuds in a reactor, liquid latex results. The dry rubber in this milky liquid is then coagulated into crumbs, washed, dried, and baled ready for shipment.

• What was the first use of rubber?

  Joseph Priestley of England, best known for his discovery of oxygen, noted that pencil marks could be “rubbed out” by the substance. From this early use, rubber derived its name.

Training

The ClassicBond One-Piece system is easy & quick to install.

Whilst it is possible to overlay your existing waterproof surface, we strongly recommend removing the existing covering back to the original deck. It is important to ensure that the deck is clean, sharp free and void of any rot. Any trapped water will continue to rot your roof.

Our One-piece membrane can be ballasted into position using a fleece cover, edge fixings and river washed pebbles, however for a more professional, long-lasting and beautiful looking roof we recommend fully bonding the membrane to the deck without the use of a ballast.

Tools Required
Scissors, Penny Roller, silicon roller for seams and joins, Roller & Brush, soft broom

Products Required
ClassicBond One Piece Membrane, Deck adhesive, Primer, contact adhesive & edge trims

7 Easy Steps

1) Prepare the roof deck by removing any old roof coverings, sharp objects that could puncture the membrane and repair any rotten decking. Note: Carry out any angle grinding of brick-work to accept the up stand trim prior to exposing roof membrane.

2) Position the One-piece membrane allowing the excess to hang over the roof. Allow the membrane to relax for approximately 30 minutes.

3) Fold one half of the membrane back and apply water-based adhesive directly onto the deck simply using a paint roller. Note: Up stands – and roof perimeter, leave a 150mm adhesive free strip on the deck so that a contact adhesive can be applied.

4) Roll the membrane back into place using a soft broom or long handled squidgy to remove any trapped air bubbles and repeat for the second half of the roof.

5) Where the roof meets an up stand and around the perimeter of the roof deck apply a 150mm strip of contact adhesive to the deck and rubber membrane. Contact adhesive must be touch dry before rolling the membrane up to the corner.

6) Repeat step 5 for the up stand applying the contact adhesive directly to the brickwork or render. Install up stand trim following instructions supplied.

7) Install Rubber4Roofs edge and gutter trims for a really professional finish.
