The Pruszyński Company guarantees that each individual order will be produced in the same color (shade). However, due to the complexity of the coating processes, slight variations in shade may occur between individual shipments. Liability for color is therefore limited to a single delivery.
For this reason, when reordering sheets from a specific batch, please indicate on the order form or inform your sales representative that this is a follow-up order and provide a color sample.
To ensure color consistency between sandwich panels and other elements, such as flashings, please order them from a single supplier.

Product Description

Valley flashings

Valley flashings are installed where two roof slopes meet at an angle, forming what is known as a roof valley. This is one of the most critical areas of the roof, where water from two roof slopes flows into a single point, creating a high risk of leaks. Valley flashings are intended to direct rainwater into the gutter system, ensuring effective drainage and protecting the roof structure. Roof valleys are most often made of galvanized or coated sheet metal, properly profiled to ensure proper water flow. Valley flashings are often reinforced with additional insulation or sealing tapes to ensure complete watertightness.

Valley gutter

The Valley gutter is the basic version of this product in our lineup. It is versatile and suits most roofs and roofing materials. The Valley gutter is manufactured on professional machinery and made from the same materials as our roof coverings, ensuring complete color consistency and the same durability as the roof itself. Additionally, specifically designed for our single-panel metal roof tiles (such as PŁASKA or PŁASKA Plus), as well as standing-seam roof panels, we offer a dedicated second variant of the basket gutter:

Do you have any questions?

What types of flashings are available for metal roof tiles?

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. You can find all the flashings available in our product range at this link: TYPICAL METAL FLASHINGS

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.

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).

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.

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.

How much do trapezoidal sheets cost?

The prices of trapezoidal sheets depend on many factors, such as the type and thickness of the protective coating, the surface finish, the sheet thickness, and the height of the trapezoidal profile. The high quality of trapezoidal sheets directly affects their price and the length of the Warranty
