Cleaning and maintenance

Roofs and façades are parts of the building that are particularly stressed by the weather. Sun and wind, rain and snow, as well as permanent moisture (in the forest or in the shade) have an effect on the building cover. Dirt deposits (e.g. dust, leaves, needles, etc.) can impair the function and appearance of the roof covering, façade or the roof drainage (e.g. blockage). Therefore, it is advisable to check and clean roof coverings and façade claddings, as well as roof drainage systems at certain intervals. In this way, changes, dirt and damage can be detected and eliminated in a timely manner and prevent consequential damage.

Depending on the degree of soiling, leaves, dirt and, if necessary, ice and snow should be removed from roof drainage systems at regular intervals. This is particularly important to consider for PREFA rain flaps, PREFA water collectors and PREFA leaf catchers. In special situations, the sieve of the water collector and the leaf catcher should be closed over the winter months. 

Tips on care and maintenance: In the case of light soiling, such as a layer of dust or similar: clear, lukewarm water, detergent or care products for car paintwork (no scouring agents!). For oil or grease: conventional car polish or suitable universal cleaner. The manufacturer’s instructions for cleaning agents must be observed. 

Use water and a cleaning sponge for cleaning.

Attention

After each cleaning process, rinse sufficiently with clear water. Do not clean in direct sunlight! Never use acetone, nitro thinner or similar solvent or products with an abrasive effect for cleaning.

Attention

For safety reasons, the gutter may not be entered or walked on!
