Pros and cons of the ventilated roof
Do you have doubts whether the ventilated roof can be an excellent solution for your home? We will help you discover in this article all the advantages and disadvantages of the ventilated roof , so you can clarify this topic and find the answers to all your doubts.
What is the ventilated roof ?
The ventilated roof , also called cold roof , is a type of coating that ensures excellent performance throughout the year, both in winter and in summer.
This solution is ideal both as an element to be taken into consideration when building a house from scratch, and as an improvement intervention on an existing home. It is very important to take care of the roof structure, as it is not an element in its own right but is the most important part of the house. It is that portion that is most exposed to climatic variations and if it is not kept correctly, it can give a whole series of problems to the entire building: starting from the upper part up to the inhabited rooms.
The ventilated roof prevents the possibility that there may be air trapped inside the upper part of the building, which in some way can also form moisture in the cavities, causing damage to the building structure. The aspect of ventilation is very important, because it ensures that fresh and clean air always enters the upper part of the house. A continuous exchange of air is therefore created, which benefits the entire structure of the house. The continuous and constant alternation of air allows to safeguard the stability of the building at the masonry level.
But how does the ventilated roof work ? This type of roof has a general scheme consisting of inclined pitches, which are accompanied by the construction of a cavity that has particular reference measurements. The thickness of the cavity must be between 6 and 10 cm in total, to ensure the functioning of the ventilated roof .

Advantages of the ventilated roof
Let's find out together the pros and advantages of the ventilated roof
|Pros of the ventilated roof|
|Elimination of condensation|
|Elimination of molds and fungi|
|Designed for safety even at low temperatures|
|Protects from sudden changes in temperature|
|Maintains a constant temperature as much as possible|
|The air is healthier|
Elimination of condensation
The circulation of air produced by the ventilated roof eliminates condensation, that is the formation of humid drops that constantly affect the structure of the housing complex. Humidity is very dangerous as it can violently consume everything in its path. This is a bit like what happens when humidity swells furniture or entrance doors, especially those of the past, deforming them due to the change in temperature. Over time these artifacts deteriorated to the point that, if they could not be fixed, they had to be totally replaced.
Elimination of molds and fungi
Another benefit of using the ventilated roofis that of the elimination of molds and fungi. In fact, in too humid environments molds are formed, which can be dangerous both for the housing structure and for the people who live inside it. Mold spores can attack the structure of the building making it fragile and destructible in this way. Secondly, the spores can also be harmful to humans. In fact, mold can lead to allergies or even to have asthma attacks: breathing unhealthy air can lead to difficult breathing. Furthermore, the spores of fungi and molds can produce toxic and dangerous substances such as ketones and alcohols in the environment. These are the elements that give the typical damp smell in environments that are not adequately ventilated.
Designed for safety even at low temperatures
Roofs that lack adequate ventilation are more exposed to the formation of ice and frozen snow. In fact, ice forms because there is no uniform temperature between the outside and the inside of the roof. Over time the snow melts, but later freezes and becomes heavy. This can cause both an overload to the roof structure and ice fall, a very dangerous factor for the inhabitants of the house, but also for passers-by who could be exposed to this event.
Protects from sudden changes in temperature
If there is proper ventilation inside the roof structure, you are more isolated from the outside and, therefore, you avoid sudden changes in temperature during the hottest hours of the day. The presence of air, in fact, can avoid that there are peaks of increase in degrees inside your home.
Maintains a constant temperature as much as possible
The ventilated roof allows to maintain a constant temperature, both in the part of the roof and in the areas below. This means that in winter it will be possible to turn on less heating and in summer the use of air conditioners will be moderate.
The air is healthier
The use of the ventilated roof ensures that the air present in the various rooms of the house is healthier, as there will not be too cold or too heated domestic areas.
Disadvantages of the ventilated roof
Let's find out together the cons and disadvantages of the ventilated roof
|Disadvantages of the ventilated roof|
|Problems in recovering spaces|
|Amplification of some noises|
The price to make a ventilated roof is quite high and can vary depending on various factors such as the materials chosen, the width of the roof surface, etc. The deductions provided for by law make it possible to recover half of the initial cost, but the problem that could arise is that of not having the initial sum to proceed with the work. So the choice to intervene on the roof must be made with awareness.
Problems in recovering spaces
Building a ventilated roof can cause problems in the recovery of spaces. Depending on the structure of the house, installing a series of layers can reduce the height of the ceiling or attic of the building, due to the thickness of these layers. It is therefore important to evaluate this aspect in advance and in the estimate with qualified professionals, in order to understand if this project can really be suitable for your needs and requirements.
Amplification of some noises
If you live in places that are not too quiet, installing a ventilated roof can cause the amplification of some noises coming from outside. In fact, the cavity can act as a real resonance chamber, capable of increasing the volume of some noises. To overcome this problem, a greater layer of insulating material is used, which however has the drawback of reducing the height of the ceiling of the room in the highest part of the house.
