The modular, certified roof maintenance concept.

Regular maintenance of a flat roof is essential if you want to enjoy a long service life and useful life. Flat roofs are subjected to heavy loads every day. They are exposed to thermal influences such as heat and, in the summer months, constant strong UV radiation. Precipitation, on the other hand, leaves your flat roof helplessly exposed to moisture and possibly even standing water. This has a negative effect on waterproofing. Over time, these weather-related influences inevitably lead to leaks in your roof.. 

Regular maintenance checks help to identify leaks or weak spots on your flat roof at an early stage. Mechanical stress on the supporting structure caused by work on superstructures or walking on the roof surface also affects the service life and useful life of your flat roof and can damage the roof waterproofing or lead to material fatigue. For the maintenance of your flat roof, take advantage of our Roof Protection Plan for professional roof management and regular inspection of your roof surfaces.
