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.

The basic flashings for modular roof tiles include: modular barge flashing, Upper barge flashing and side barge flashings, Omega and barrel-shaped ridge caps, ventilation eaves battens, valley gutters, sidewall flashings, under-gutter strips, over-gutter flashing, and drainage gutters.

Yes, modular roof tiles are relatively easy to assemble. Thanks to their small size and light weight, modular roof tiles pose no assembly problems, even on complex roofs with steep slopes. During assembly, be sure to handle the metal roof tiles properly (e.g., avoid using tools that could damage the protective coating). Assembly can be made even easier by using standard flashings, such as ridge flashings, over- and under-gutter flashing, valley gutters, and barge flashings.

Installing photovoltaic panels on modular roof tiles is a viable and widely used option. The durability of the roofing material, a specific mounting system designed for panel roof tiles, and safety are the key factors that must be considered for this type of assembly. Many manufacturers also offer special mounting brackets for photovoltaic panels that are compatible with various models of metal roof tiles. These brackets ensure the safe and proper assembly of the panels. You can find the mounting brackets available in our product range at this link: Photovoltaics Brackets
