Extreme strains caused by snow, hail, rain, cold and heat. Add to that the exposure to atmospheric conditions like UV- and infrared rays, leading to the aging of the material plus sediments of dust and dirt, causing unwanted growth of plants. In addition to that, structural stresses strain the roof as a construction part. The failure of the roof’s sealing has mostly grave consequences including damages of the roof construction, the roof system and the building itself.
o never let it get so far and to avoid high financial charges the owner should leave nothing to chance when it comes to flat roof constructions and should rely on an expert’s maintenance to diminish the many risks. Prevention and maintenance can secure a long serviceable life of a professionally constructed roof. inplastics has compiled for you the most important care and maintenance works for a professional inspection. Comprehensive information is available in the Professional Rules. Roof inspections, maintenance and restoration are integral parts of the “Guidelines for Flat Roofs” (2005) as well as the DIN 18531 regulation (Sealings of roofs, that are not in use, 2005). In addition, the relevant technical literature points out the necessity of care and maintenance. For greened roofs, the services defined in the “Green Roof Guidelines” (FLL, 2008) are to be considered. Supplementary information is available from the “Principles of Care and Maintenance of Roof Greening” (2002). The minimum requirements defined in the Professional Rules should always be he contractual basis of any maintenance contract.
A maintenance plan for inspections guarantees that all necessary measures are taken and that the roof will be fully functional even after many years. Like a specification sheet the plan keeps record about when inspections have to be held and what works have to be carried out. In case of the roof being insured, the maintenance plan constitutes a written documentation of the professional maintenance, which is the requirement for sustaining an insurance cover. In most cases, the insurance cover seizes if the maintenance works are not documented or carried out in due time. This is also valid for material- and system guarantees. Most manufacturers combine such (voluntary) guaranteeing with a maintenance contract. Assurance companies like Allianz and R+V offer insurances from 15 years (Allianz) to 20 years (R+V). To make sure that the building’s owner always has the maintenance book at his or her disposal it should be kept with the building passport. In the case of a change in ownership the maintenance plan has to be transferred to the new owner. For professional and regular inspections it is advisable to close a maintenance contract with a specialist. Roof areas are usually maintained in spring and in autumn. The type and range of the necessary maintenance works depend on the type of flat roof e.g. extensive roof greenings require far more comprehensive care and maintenance than roof constructions without any superimposed load. In addition to the standard maintenance works, roof greenings have to be – if necessary – re-planted, fertilized or watered and the drainage facilities have to be cleaned of plant cover, leaves and other sediments so as to ensure the proper drainage
of rainwater at any given time.
The following maintenance works should be the minimum services carried out regularly:
• cleaning of roof gutters and down pipes as well as other drainage facilities
• removal of severe dirt sediment
• cleaning of gravel beds especially from unwanted plant cover
• inspection of silicone grooves
• inspection of fittings and exclusions of built-in components
• rust prevention on metal parts
• replacement of damaged roof materials
• surface protection on roof sheets
• restoration of damaged façade fittings
• inspection of the joints of uncovered roof areas
• inspection and cleaning of rooflight domes and other lighting elements
• inspection of running boards and other mounting parts
