Roof service life
All SPRA membrane products must have current independent certification from British Board of Agrément or BRE Global. These state anticipated service life based on field study and artificial ageing and range from 25-40 years.
Single ply membranes themselves require no maintenance during service. However, subject to safe access being available, it is recommended that all roofs are inspected once or preferably twice per year to check for damage, obstructed rainwater outlets, condition of designated walkways and so on. Single ply membranes can be cleaned if required using water and a soft brush.

Compliance with education and health technical criteria
Over 60% of UK construction is refurbishment and it is challenging, given the demands of carbon reduction, IT integration and safety considerations. Single ply is available in three methods of attachment and two system options, with the added bonus of compatibility with green roof systems. SPRA members have the experience to offer durable, low carbon yet attractive solutions. No use of hot materials or disruptive plant means work can often be done during continuous occupation of the building.
