What materials are best for a flat roof replacement? To replace a flat roof, we recommend using a modern rubber membrane and a suitable water-based deck adhesive. If you are installing onto concrete or metal, rather than a timber deck, use a roofing bonding adhesive instead. Flat roofs with rubber membrane can be fully sealed with an edge and gutter trim system.
How to repair a flat roof. Depending on the nature and scale of the damage and the type of roofing installed, a flat roof can be repaired in several ways. First identify the source of the leak and locate the damaged area. Prepare the surface for a patch repair on a rubber roof and apply an EPDM patch to a clean, primed surface. Seal cracks
What is a flat roof? A flat roof is never truly flat but is instead installed with a slight fall to allow rainwater to runoff efficiently. Typically, this gradient is designed to a minimum fall of 1:40. The gradient can be created during the timber deck construction or with the use of tapered insulation boards beneath the membrane.
What is EPDM roofing? Ethylene Propylene Diene Monomer (EPDM) is a synthetic rubber, single-ply membrane popular in flat roofing. EPDM can elongate over 300%, is durable, UV stable, temperature and weather resistant with a service life expectancy of 50 years. EPDM roof systems are commonly used in domestic and commercial installations.
To waterproof a shed, we recommend using an EPDM membrane. Start by measuring the length and width to calculate the size of the membrane you will need. Add 300mm to allow for overhang. Strip back the old roof covering and prepare the surface area, before applying adhesive and the new EPDM membrane.
Sedum vegetation can be placed over the RubberCover EPDM membrane, provided that a root-resistant geotextile is used between the vegetation and the membrane. A distance of 30 cm must be taken into account between the vegetation and every roof installation detail.
