Yes, installation of EPDM is weather dependent. EPDM should only be installed in dry weather conditions. Do not install membrane if it is raining or if temperatures are below five degrees. Temperature is important, particularly if installing EPDM using water-based adhesives on a timber deck.
Blue roofing is designed to temporarily retain rainwater above the waterproofing layer. The water is gradually released at a pre-determined rate back into the local surface water drainage system. The purpose of blue roofing is to reduce the pressure on water systems, particularly in urban areas.
There are no specific materials that damage EPDM membrane. Damage that can occur is often accidental and caused by debris, such as tree branches falling during a storm. It is advisable to wear suitable footwear when installing EPDM, so that you do not accidentally puncture the membrane.
A breather membrane is a permeable, breathable layer that allows water vapour to escape roofing without the need for additional ventilation. It is used to reduce damp and condensation and acts as a secondary barrier to wind-driven rain. It should not be relied upon for primary waterproofing.
The Kingspan TR27 PIR insulation boards should be laid on a clean surface, free of debris. Suitable for a wide range of substrates and can be mechanically fixed or bonded. There are a variety of fixing patterns, depending on the specifics of the project. The correct fasteners and fixing patterns must be used in accordance with the manufacturer's guidelines.
Using a membrane as the base layer of a green roof gives the roof deck the waterproofing it needs. This is because green roofs become saturated with water through the planting mediums. We would recommend EPDM, which is available in large sheets, minimising the need for joins and often covering the project in a single piece.
We would always recommend that a new plywood roof is waterproofed with a membrane. Lay out the EPDM to rest in situ for 30 minutes, then fold back to expose the working area. Apply the adhesive to the deck and the membrane and leave to go off, before rolling the membrane back over the exposed roof and smoothing with a brush.
Clogged gutters can lead to serious damage to roofing decks and timbers if left for a length of time. When water cannot flow through the gutters freely, they quickly overflow and can track down roofing timbers. Over time, this can result in rot, which will mean replacing or repairing the roof structure. This is why it is important to address any issues as a priority.
EPDM sheet membrane can be custom-cut to a maximum of 60m x 15m in a single piece at PermaRoof UK.
What colour does EPDM membrane come in? RubberCover EPDM membrane is available in one colour – referred to as either slate grey or black.
