EAVE flashings

Eaves flashings are one of the most important technical details of a roof, responsible not only for the aesthetic finishing of the slope edges, but above all for the proper functioning of the entire roofing system.

The most important tasks of eaves flashings include:

effective drainage of rainwater and meltwater into the gutter system,
protecting the roof layers against capillary rising,
protection of the eaves structure, fascia board, and facade against moisture,
ensuring the tightness of the roofing in the eaves area,
protecting the slope against wind-blown rain, snow, and strong winds,
ensuring proper ventilation of the roof slope,
drainage of condensate and moisture from the initial covering layer,
increasing the durability and operational safety of the roof.

Particular attention should be paid to the correct connection of eaves flashings with the roof membrane, gutter system, and ventilation elements. An incorrectly executed eaves detail can lead to moisture in the thermal insulation, degradation of the wooden structure, and limited effectiveness of the roof slope ventilation.

Under-gutter flashing

UNDER-GUTTER flashing is a roofing element responsible for protecting the slope and the facade against water seepage. It particularly protects the fascia board to which it is mounted, as well as the building wall, from the effects of rain, especially during heavy rainfall. For full roof functionality, especially in the eave area, we recommend installing other eave flashings alongside UNDER-GUTTER flashings, including OVER-GUTTER flashings from our offer:

Do you have questions?

Is it possible to make copper machining at the steel roof?

When using copper, be careful because copper oxides are very aggressive and cause corrosion of other metals. Therefore, on buildings, it cannot be combined with other metal species (copper enters into contact and causes electrolytic corrosion of other metals).

Why is the metal roofing sheets recommended for the renovation of old roofs?

This is directly related to its low weight. In the case of old roofs, the trusses of the renovated houses are often somewhat damaged by time. Therefore, it is safer to use a metal roofing tile, which weight oscillates at 4.7 kg/m2, than almost ten times a heavier ceramic tile than it. However, it is always worth verifying the condition of the roof truss, with a specialist and make sure that it does not require renovation or replacement. In such cases, the safety of residents or building employees, as well as the assembly team, is always a priority. In most situations, however, the condition of the structure without major problems allows the use of roof tiles, while the use of ceramic tile would not be possible.

Can you use an angle grinder when cutting sheets?

Modern roofing exclude the use of angle grinders for cutting. The use of this method of cutting the material is associated with the loss of warranty.The angle grinder during operation and cutting produces very large amounts of heat, which in turn damages the edges of the sheet, as well as the coating covering it. In addition, the filings extracting during operation blend into the surface of the blades, additionally creating potential corrosion outbreaks.The right way of cutting sheet metal is to use automatic jumps (so -called Nilerler) or hand scissors. They use the mechanical force to cut the sheet, without exposing it to high temperature jumps. In addition, it is worth remembering that after cutting it is good to train cut places with dedicated protective varnish or special paint.

Does the roof require maintenance?

Yes, each roof requires periodic inspections to check if there have been any damage. Most of the products offered by Blachy Pruszyński have various types of specialized coatings available (covered by the warranty), increasing the life and durability of sheet metal. Maintenance consists mainly in removing the deposits and chimney dust, which left for a longer period of time can lead to sheet metal damage. Particular attention should be paid to places around chimneys that are sensitive due to more demanding operating conditions. If during the coverage inspection, local damage to the paint coating will be noticed, paint corrections should be made. In such a situation, the best solution is to use dedicated gloss paints tailored to a given coating. Such paints are in a stringent offer of Pruszyńska sheet and it is strongly recommended to use company products, recommended for a given coating.

How to register and how does the warranty work?

In order to register the warranty, download the warranty registration available in files for download / printing or directly: Warranty registration and send it completed to the following address: guarantee@pruszynski.euThe warranty begins to apply on the day of purchase of the goods.
