Roof hatches are special openings in the roof that provide access to its surface. They are often used when it is necessary to regularly or periodically climb the roof, for example to inspect, maintain or repair installations on the roof.

These products are also often used to access flat roofs or roofs with slopes where there are no fixed stairs or ladders to access the roof surface. This allows them to serve as a convenient entry point, especially when roof work needs to be carried out.
In some cases, such exits to the roof are also used as a source of daylight, as they allow natural light to enter the rooms under the roof.
About the function of roof hatch is a kind of hatch that has the additional function of letting daylight through. They work by letting sunlight into the rooms under the roof, which makes it possible to reduce the cost of electricity needed to illuminate these rooms during the day.

Building regulations
Polish law regulates the issue of roof hatches as part of the construction regulations. These regulations are designed to ensure the safety of people who use roof hatches, as well as to ensure that the articles will meet certain technical requirements.
In Poland, technical standards for construction specify requirements for roof hatches, including dimensions, load capacity and method of installation. These provisions can be found, m.in others, in the following legal acts:
- Construction law – specifies that they must be made in accordance with technical requirements and must not pose a threat to people or property.
- The Regulation of the Minister of Infrastructure on the technical conditions to be met by buildings and their location – contains detailed technical requirements for exits / entrances to the roof, including minimum dimensions and load capacity.
- Building standards – in Poland, there are a number of construction standards that regulate various aspects of construction, including requirements for elements that facilitate access to the roof.
It is important that they are carried out in accordance with the law and technical standards, because an improperly made element can pose a threat to the safety of people using the roof or under it.
Gravitational ventilation
Such an opening in the roof sheathing can have a significant impact on the natural ventilation in the building. Gravitational ventilation is based on the natural flow of air inside the building, which is created as a result of differences in air pressure. If there is an exit to the roof installed in the building, it affects these pressure differences and thus the gravitational ventilation.
Such roof exits are usually equipped with special ventilation elements, such as ventilation grilles or air penetrations, which allow air to flow between the interior of the building and the outside. In this way, air can flow through the skylight and provide additional ventilation for the rooms under the roof.
If there is no exit to the roof in the building, natural ventilation may be limited, which can lead to increased humidity in rooms and the appearance of fungi and mold. Therefore, if your building lacks proper ventilation, installing a roof hatch can help improve indoor climates.
Materials
Good quality exits to the roof should be made of materials that are resistant to weather conditions, durable, and resistant to mechanical loads. Depending on the application, they can be made of different materials.
Aluminium – it is a light and durable material that is resistant to corrosion and weather conditions. Outputs made of aluminium are easy to install and have an aesthetic appearance.
Stainless steel – is a material that is characterized by resistance to corrosion and weather conditions. Roof exits made of this material are durable and resistant to mechanical damage.
Plastics – e.g. polycarbonate, acrylic or PVC, are materials that are characterized by low weight, ease of processing, and resistance to weather conditions. Roof exits made of plastic are easy to install and have an aesthetic appearance.
Glass – tempered or laminated glass are materials that are characterized by exceptional resistance to weather conditions and a low degree of deformability. Exits to the roof made of glass are aesthetic and allow for better lighting of the rooms.
Thermal insulation – Insulated roof access window is a special door that allows access to the roof from the attic level, which is additionally insulated to ensure better thermal insulation of rooms in the attic. This solution is particularly important in buildings where the attic serves a residential or utility function.
Avoid buying poor or poor quality solutions
Roof elements of unknown production and origin should be avoided because they do not have the right quality and do not meet the requirements for these products. They can be made of low-quality materials, leading to faster wear and damage, and they may not meet safety standards, which poses a risk to users and leads to serious accidents.
In the case of products manufactured in China, special care must be taken, as in recent years there have been many cases of roofing elements of this origin that did not meet quality and safety standards. Many manufacturers from China try to reduce production costs at the expense of quality, as well as use dangerous and unsuitable materials. In addition, roofing products from China do not always fully comply with European requirements, which can lead to problems during installation and use, and can also cause problems with warranty and after-sales service.
Therefore, if you want to be sure of the quality and safety of the roof hatch, it is worth choosing products from proven manufacturers from the EU or other countries who offer products that meet high quality and safety standards. Choosing a high-quality roof access window is especially important for buildings with a higher height, where access to the roof is difficult and potentially dangerous.
