Roof maintenance, as with any part of the building, is essential in order to comply with the waterproofing system guarantee and to ensure maximum performance and life expectancy.


Access to the roof must only be allowed under supervision of the BuildingManager or the person responsible for building maintenance.All personnel given permission to access the roof must be instructed touse the dedicated access/walkways provided and be fully advised of thehealth and safety procedures required by the site or that of the individualroof concerned. Where roof working/access, other than light foot trafficis required, adequate protection must be provided.


During routine maintenance to plant or the building fabric, the flat roofingsystem must be protected against damage by point loading, spillages ofsolvents and sharp objects such as nails, fixings, trims, glazing panels etc.The roof must not be used as a storage area.Any materials used by following trades must be cleared on completion.


Additional units, penetration or fixings that may be required should be referredto IKO Polymeric or the original roofing contractor prior to any works beingcarried out.Any approved additional waterproofing works must be carried out withthe full knowledge of IKO Polymeric and by the IKO Polymeric approvedcontractor.


The roofing should be inspected twice yearly, preferably in the spring andautumn, and/or after extremes of weather conditions.

It is important to check the following:

  • Check that roof outlets are functioning and gratings arenot blocked.
  • Check waterproofing to roof light kerbs.
  • Check flashings to perimeter upstands, ensuring metal cappings aresecure.
  • Check flashings to expansion joints and that cappings are secure.
  • Check upstand flashings to support legs.
  • Check walkways and around access points to ensuredamage/displacement has not occurred to walkway or concretepaviours.

Any algal growth or silt build up should be cleaned off using a soft bristlebroom and clean water.

Check condition of any flexible sealants in use that they still provide aweatherproof finish; arrange to replace any that are not.


Generally clean water and a soft broom should be used. A mild householddetergent can be added to the water. The area should be hosed with cleanwater on completion. Please contact the local authority for approval for the useof any detergents that may wash into the drainage system.

Accidental Damage

In the event of accidental damage occurring to the membrane, the installingcontractor and/or IKO Polymeric should be notified immediately in order that apractical solution to the problem can be agreed and any remedial actions taken.Failure to make contact with IKO Polymeric could invalidate any guarantees. As a temporary measure a self-adhesive tape can be applied to the surface of the membrane to prevent water ingress. Under no circumstances should a bituminous based tape product be used.
