Mosses and lichens most often attack roof tiles on shaded sections of the roof, especially when the house is located near a forest or in an area sheltered by trees. They are particularly fond of natural ceramic and cement roof tiles, as well as metal roofing. But they can also appear on glazed ceramic roof tiles with a very smooth surface. It’s only a matter of time.

In such situations, we recommend using a specialized product designed to remove algae, moss, and lichen—for example, products from ALTAX. Most products of this type are relatively easy to use — simply spray the moss and lichen generously, and after a few days, rinse the dead vegetation with water—most of it should wash away on its own, and the rest should be removed with a brush and clean water (without detergents). It’s also worth remembering that once the roof has dried, you should spray its surface again with a suitable protective treatment and let it dry. This will protect the surface from regrowth, as the protective treatments will significantly delay the process.

Keep in mind that fungicides and algicides are strong chemicals, so you must exercise extreme caution when applying them. Gloves and safety goggles are required. Another very important aspect is to protect the area around the building so that water containing chemicals does not run directly into the soil or flower beds. The best solution is to block the outlets of downspouts, for example by placing plastic barrels or containers underneath to catch the water containing the chemicals.

Caution must be exercised when using copper, as copper oxides are highly corrosive and cause corrosion of other metals. For this reason, it must not be combined with other types of metals on buildings (copper reacts upon contact and causes electrolytic corrosion of other metals).

This is directly related to its light weight. In the case of old roofs, the roof trusses of renovated houses are often already somewhat worn down by time. Therefore, it is safer to use metal roof tiles, which weigh around 4.7 kg/m², rather than ceramic roof tiles, which are nearly ten times heavier. However, it’s always a good idea to have a specialist inspect the condition of the roof truss and confirm whether it requires renovation or replacement after all. In such cases, the safety of the building’s residents or employees, as well as the installation crew, is always the top priority. In most situations, however, the condition of the structure allows for the use of metal roof tiles without major issues, whereas the use of ceramic roof tiles would no longer be possible.

Modern roof coverings preclude the use of angle grinders for cutting. Using this method to cut the material will void the Warranty.
An angle grinder generates a great deal of heat during operation and cutting, which in turn damages the edges of the sheet metal as well as its protective coating. Additionally, the metal shavings produced during operation become embedded in the sheet metal’s surface, creating potential corrosion sites.
The proper way to cut sheet metal is to use automatic nibblers or hand shears. These tools use mechanical force to cut the sheet metal without exposing it to extreme temperature fluctuations. Additionally, it’s worth remembering that after cutting, it’s a good idea to protect the cut edges with a dedicated protective varnish or special paint.

Yes, every roof requires periodic inspections to check for any damage. Most products offered by the Blachy Pruszyński Company are available with various types of specialized coatings (covered by Warranty) that increase the service life and durability of metal roofing. Maintenance mainly involves removing soot and chimney dust, which, if left for an extended period, can damage the metal sheeting. Particular attention should be paid to the areas around chimneys, which are critical due to more demanding operating conditions. If localized damage to the paint coating is noticed during an inspection of the roofing, touch-up painting should be performed. In such situations, the best solution is to use dedicated touch-up paints matched to the specific coating. The Blachy Pruszyński Company offers such paints as part of its regular product line, and it is strongly recommended to use the company’s products that are recommended for the specific coating.
