Recommendations

Transport and storage

Packages should be stored in dry and well-ventilated spaces, without humidity condensation between the sheets. Collective packages should be put on blocks about 20cm height upon the surface. If panels are stored more than 3 weeks from the production date – panels should be checked and separators should be put between to allow for free air circulation. All information about the way and period of storage are on the protective foil, product labels and our catalogues, assembly instructions and website.
Protective foil is used to safe the roof panels against mechanical damages. It should be removed directly at the assembly stage and it should protect panels against humidity and sun during the storage period. Non compliance with above rules may cause difficulties when removing the foil from sheets and dirty after the glue

Maintenance and washing

In order to extend durability of roofs and elevations it’s recommended to check and conservative it.
Inspection – One time a year (it’s best in spring) there should be inspection of roof/elevation in order to early detection of possible damage.
Cleaning of steel sheet – Roof and elevation made of steel sheets require cleaning at least once a year. Stratifying dirt on steel sheet may cause uneven discoloration of lacquer (because of uneven impact of UV beams), and lower protection to corrosion(dust traps humidity on steel sheets which causes damage). Dirty and stained spots can be cleaned by soft brush and water (temp. max. 60c). If it is necessary it is permitted to use some light detergent (ph 6/7, max 10% solution). There also can be used pressed water(max. 100bar) to cleaning, however the beam of water cannot be applicated too near of surface of sheets(min. 30 cm), also it shouldn’t be perpendicularly to surface. Near the connections water beam should be directed to bottom, to avoid water of entering cracks near connections. With old surfaces of steel sheets we should deal with high cautiously. Cleaning should be conducted from top to bottom, and cleaned spots should be rinsed out immediately.
It is not permitted to use scouring powders, nitro solvent, chlorine liquor, aromatised substances, substances with Amon chloride or sodium.
Damages – Possible damages during guarantee should be consulted with Contractor of roof/elevation and can be repaired only with his written permission.Repair of damages on small surfaces is done with quick-drying varnish. However painting big surfaces should be done with special industrial paints to renovating coverings. Painting should be limited only to special damaged spots (scratches to steel, centres of corrosion etc.)Preparation of surface to painting should be done with generally accepted rules. It is necessary to precisely remove all signs of corrosion – best with special brush or close-grained sandpaper. Then that surface should be undusted, degreased and cleaned. To degrease extraction naptha or water with addition of surfactant(best with 1-2%solution of ammoniac) can be used. Repaired spots may be different in colour compared to original steel sheets because of natural impact of atmospheric phenomenon (ageing of varnish due to impact of UV radiation)
ATTENTION!– During inspecting, cleaning, conservation and repair all work safety regulations should be obeyed.Pruszyński Sp. z o.o. is not in charge of possible accidents during carrying out all following actions.

Do you have questions?

Is it possible to install copper flashings on a steel roof?

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).

Why are metal roof tiles recommended for renovating old roofs?

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.

Can I use an angle grinder to cut sheets?

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.

Does the roof need maintenance?

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.
